Irrigation is the key point of orchard maintenance. Fruit trees in the north are prone to drought when there is insufficient precipitation in early spring. Fruit trees are in a period of vigorous growth and must have sufficient water sources. Therefore, adopting spring irrigation and moisture conservation farming techniques to prevent spring drought is the key to increasing yield. There are many orchards in the mountains in the south, and the irrigation conditions are limited, and droughts are prone to occur in summer. Therefore, the adoption of irrigation and water-storage cultivation is an important measure to ensure high yield and high quality. 2. The orchard hole storage fertilizer and water plus plastic film covering technology. This technology has low application cost, is easy to operate, can improve soil, and can increase yield and increase fruit. Currently, it has been promoted in Shandong, Hebei, Shanxi, Liaoning, Shaanxi and other places for millions of hectares, which can increase yield by about 20-30%. 3. The orchard infiltration irrigation, drip irrigation, sprinkler irrigation and other technologies have been gradually promoted, and the yield has been significantly increased. Among them, the efficient and practical infiltration irrigation technology can save water as high as 60%-80%. Brief introduction of several common water-saving irrigation techniques: 1. Wide hole fertilizer storage technology: After the soil is thawed in spring, 4-8 circular soil holes are dug under the tree canopy. The hole diameter is about 30 cm and the depth is 30-40 cm. Grass handle, and then use 50 grams of urea, 50-100 grams of superphosphate, 50-100 grams of potassium chloride, mix with soil, fill around the grass handle, cover soil for 1 cm, then cover with mulch, and poke a hole with As an import for future watering and fertilization, the orifice is usually covered with clods. 2. Infiltration irrigation. It is an irrigation method in which water seeps from the ground to the soil, which can save 70-80% of water compared with flood irrigation. It is a water-saving technology with less investment, labor saving and high efficiency. 3. Drip irrigation, sprinkler irrigation, micro-sprinkler irrigation. Drip irrigation is widely used, low cost, labor-saving and simple, and is more suitable for mountain orchards. Complete equipment and technology are available for purchase. Care should be taken to prevent clogging. Sprinkler irrigation is more suitable for flat orchards. Supporting equipment and special technology can also be purchased. The latest micro-sprinkler irrigation technology is more resistant to clogging than drip irrigation, and the effect is better by using local spring irrigation.

Precautions for the use and maintenance of drip irrigation belts 1. The pipes and drippers of drip irrigation are easy to block and have high water quality requirements, so it is necessary to install filters; 2. Drip irrigation cannot adjust the microclimate of the field, and is not suitable for irrigation during the freezing period, and the drip irrigation system cannot be used in vegetable irrigation. . 3. The investment in drip irrigation is high, and the economic benefits of crops should be considered; 4. Pay attention to pressing and compacting the film when laying the drip irrigation belt, so that the film is as close to the drip irrigation belt as possible, and there should be no space between the film and the drip irrigation belt. Avoid the sunlight passing through the condensation formed by the water droplets. Before planting, the land should be leveled to reduce the phenomenon of many pits and depressions in the land. Prevent clods, rocks and weeds from holding up the mulch, causing water vapor to accumulate under the mulch to form a lens effect and burn the drip irrigation belt. When laying, the drip irrigation tape can be buried to avoid focus burns. The correct use of the patch drip irrigation tape is as follows: 1. SMD drip irrigation tape should pay attention to the water pressure. The pressure should be moderate to avoid rupture of the soft tape of the patch drip irrigation tape. 2. The proportion of fertilizer nutrients is suitable. 3. Prevent patch drip irrigation tape from being blocked. Clean the filter regularly, and make sure to dissolve it well and remove impurities when topdressing. 4. Keep the plastic pipes well. When not in use in summer, the pipes and soft belts placed on the ground should be collected and stored in a place protected from light and low temperature. When reused, check for cracks, leaks or blockages, and then re-arrange them after maintenance.

1. Fit the pipe belt accessories according to the row spacing, and measure the pipe belt and the supervisor. 2. Installation, one end of the main belt is connected with the hose (the hose is connected with the pressure water source and water pump), the other end is connected with the accessories, the micro spray belt is connected behind the accessories, and the tail is sealed. If there are small drop holes and impurities blocked, you can untie the tail of the micro-spray belt and rinse with water for about one minute. Scope of application: 1, suitable for wheat, corn and other crops, can also be used for seedlings, fruit trees sprinkler irrigation. 2, suitable for planting crops relatively short, does not affect the spraying of micro-spray belt, such as: lawn. 3, and other: vegetables, mushrooms, nurseries, orchards, flowers, greenhouse cultivation crops and so on. 4. It can also be applied to the micro-spray belt under the film. The spray belt is laid under the plastic film, and the water flow can form the drip irrigation effect under the shelter of the plastic film. 5, can also be used for greenhouse irrigation, field crop irrigation

Farmer friends are blessed! In the upcoming 2021, the state will further intensify agricultural subsidies for farmers, and the agricultural NongCunBu Treasury about to do a good job of agricultural production development project implementation in 2020 of the notice as mentioned in the, improve the optimization of agricultural machinery purchase subsidy and the full implementation of green ecological oriented agricultural subsidy system reform. So what kind of subsidies will farmers receive in the New Year? Small farmers lead everyone to understand it together! First, land transfer subsidies In recent years, the state has advocated land transfer and allocated special funds to subsidize it. For large farmers, a sum of money can be received every year! It should be noted that to receive this subsidy, the main qualification is to have a stable land transfer relationship, land transfer period of more than 3 years, and a single land transfer area of more than 1,000 mu (land share cooperative shareholding area of more than 300 mu). There are also some qualifications, because each place may differ, farmers can consult the village committee. In addition, small farmers in Shandong province, for example, will receive a fixed subsidy of 1 million yuan for each household with a planting area of 4,000 mu. The planting area is 400 mu, and the subsidy for each mu is 230 yuan. 2. Rural low-income subsidies With the deepening of poverty alleviation efforts, the number of poor people in China has dropped significantly, but the government will provide subsidies to poor rural people who are below the subsistence allowance standard. For eligible farmers, the village committee will collect information and include them into the scope of extreme poverty. For registered poor and subsistence allowance families, living subsidies will be provided accordingly, usually at 800 yuan and 400 yuan per year. Therefore, water-saving irrigation products will also be actively applied in the market

Water-saving irrigation scientific irrigation is an irrigation method that professional irrigation enterprises have been trying to promote, including drip irrigation, micro-jet irrigation, infiltration irrigation, sprinkler irrigation and other modern irrigation methods. , It is important to make a reasonable design according to the zero water characteristics, growth stage, climate, ten soil conditions of the corresponding fine matter, and formulate the corresponding irrigation system. the Local precise irrigation can be achieved by using dry water supplement to meet the important needs of orange growth. Besides, fertilizers and pesticides can be dissolved in water and combined with fertilizer injection pump Fertilizing and dosing operations were carried out by the substituting fertilizing device. Also can avoid the soil salinization, has appeared in the soil salinization, irrigation can be used to wash the soluble salt in the soil, to improve the soil. In addition, scientific irrigation can prevent fruit trees and vegetables from freezing, dry hot air and wind erosion. The advantages of water-saving irrigation Scientific irrigation can effectively maintain ten soil water, water, fertilizer. The good state of each phase, such as gas and heat, has many advantages, such as saving water, saving labor, saving energy, saving fertilizer, increasing production and income, etc., is gradually recognized and used by everyone, but due to the lack of capital and understanding, there is still a lot of work to be done by peers in the industry. Since modern times, with the rapid increase of population and the increasingly developed economy, the prominent contradiction between supply and demand of water resources has also been reflected in the irrigation industry worldwide. In addition, there are also problems such as further reducing construction and operation costs, improving irrigation benefits, and preventing the salinization and swamping of irrigated land. On the other hand, there is a serious problem that many water-saving irrigation projects do not work at all. Many countries have shifted the focus of irrigation development from developing new irrigated areas to rebuilding old irrigated areas and strengthening irrigation management Transfer. On the basis of absorbing the achievements of modern science and technology, irrigation technology will develop towards the direction of saving water and energy, optimizing dispatching, modern management, monitoring and forecasting, etc. In some areas of northwest, North and northeast China, where water resources are in serious shortage, water-saving irrigation and water-saving agriculture have become urgent affairs. It is also necessary to develop scientific irrigation methods in modern facility agriculture, horticulture and garden construction, which are flourishing in east and south China

Water-saving irrigation is a modern engineering technology. Whether it is engineering water-saving, agricultural water-saving and management water-saving, it must be established on the basis of industrial production of water-saving irrigation materials and equipment. It can be said that this is one of the prerequisites to be solved for large-scale and water-saving irrigation. Through more than 20 years of efforts, China has established a certain foundation in the research and engineering practice of water-saving irrigation technology. By contrast, the development of support industry and related industries is slow and difficult to adapt to the needs of large-scale popularization of water-saving irrigation, and the current situation is not optimistic. The equipment used in different forms of water-saving irrigation projects have certain commonalities, but most of them are characteristics, so the equipment is usually developed and matched around various water-saving irrigation technologies, forming their own systems. The current market demand process material equipment, pipeline water engineering material equipment and so on. Irrigation equipment: China's production of irrigation equipment is mainly large, medium, small, light irrigation machines, irrigation pumps, irrigation land buried pipes and ground mobile pipes, sprinkler heads, auxiliary equipment, etc. China's sprinkler irrigation project area has reached 19 million mu, of which about 75% use light and small sprinkler, large and medium-sized sprinkler irrigation area accounts for about 10%, semi-fixed pipe sprinkler irrigation accounts for about 15%. Micro irrigation equipment: the micro irrigation equipment produced in China mainly includes filter, fertilizer and other first hub equipment, pipes and connectors, drip irrigation pipe (belt), micro sprinkler head, infiltration irrigation pipe, etc. According to statistics, by the end of 1997 China's micro-irrigation area has reached 2 million mu, mainly used for fruit trees and facilities of agricultural crops irrigation. It is essential to realize precise irrigation automatic control equipment. Although such equipment has been developed in China, it has not formed products. In the future, we should guide the work in this respect to improve the supporting capacity and overall level of micro-irrigation equipment in China. Channel anti-seepage new materials and construction machinery: membrane material anti-seepage performance is good, adapt to deformation ability, simple construction, low cost advantages, widely used, China in the mid-1960s has used membrane material for channel anti-seepage, but there was no special anti-seepage membrane material. Low-pressure pipeline water conveyance equipment: During the seventh Five-year Plan period, the former State Science and Technology Commission and the Ministry of Water Resources organized key research on low-pressure pipeline water conveyance technology to meet the needs of water-saving in well irrigated areas, which promoted the development of related industries. Low pressure pipeline technology in China is in the early 80 s water saving irrigation urgent mission, but the shortage of investment and cases, in the developed area, therefore, positioning technology is low, the system positioning depend, to promote the all-round development of related industry, in turn, also restrict the development of the pipeline technology and expand in the field of application. Water-saving irrigation materials and equipment come from the enterprises that produce them, and the current situation of enterprises reflects the situation of products to a certain extent. The production scale is small: the products of many enterprises only account for a part or a small part of special materials and equipment for water-saving irrigation. The small scale of production restricts the development of enterprises, and also seriously restricts the updating and quality improvement of water-saving irrigation materials and equipment. Low degree of specialization: Many of the enterprises producing special materials and equipment for water-saving irrigation in China are based on the original production field, and some of them are converted to produce water-saving irrigation materials and equipment. Therefore, most of them are not specialized factories, with complex product structure and weak correlation. This situation determines that the production organization form is small batch production with common equipment and common technology, which makes it difficult to guarantee product quality and reduce production cost. Backward production technology and equipment, into the water saving irrigation production enterprise, is often seen in the 70 s and '60 s and 50 s production equipment, these devices have a plenty of the factory equipment, have is sell to the big businesses obsolete equipment, backward production technology and equipment also is one of the backward of the production process. Lack the action of industry bibcock enterprise: small and scattered processing production does not mean lag behind certainly, the key is to want to have bibcock enterprise to develop the action of main engine factory, small enterprise should undertake specialization around bibcock enterprise to produce.

Labyrinth-type drip irrigation belt installation instructions Drip irrigation water generally goes through pressure stabilization, filtration and fertilization at the head hub, then through the main pipe and branch pipe, and finally drops to the root of the plant by drip irrigation belt. The installation of drip irrigation belt is divided into the following steps: 1. Drill holes on the branch pipe The polyethylene branch pipe is first drilled with a special drilling tool. 2. The water pipe is connected with the drip irrigation belt As shown in the figure, a special bypass is used to connect the water delivery branch pipe with the drip irrigation belt. 3, cleaning and head After the drip irrigation belt and water pipe are installed according to steps 1 and 2, the water supply valve should be opened for flushing, and the impurities remaining in the system and drip irrigation belt should be washed away. Finally, the end of drip irrigation belt should be folded in two, and the end should be sealed with the cut drip irrigation head, as shown in the following Operation and use conditions of labyrinth drip irrigation belt 1. Drip irrigation belt must be used at an ambient temperature greater than 0℃. 2. Drip irrigation water must be filtered through a filter of more than 120 mesh. 3. When drip irrigation is carried out, it is necessary to slowly open the water main switch and gradually reach the rated working pressure, so as to avoid the damage to drip irrigation system caused by the instantaneous high pressure caused by the sudden opening of the valve. 4. When the drip irrigation belt is laid, the convex surface of the labyrinth runner should be upward. 5. Shear drip irrigation belt should be cut vertically, and the shear position should be between two flow channels. 6. The drip irrigation belt is used on the ground, and must not be buried underground.

Note when using microjet tape 1. Before laying the micro-spray belt, it is necessary to remove the pests in the soil with drugs to prevent them from harming crops and biting the micro-spray belt. 2. When laying, the micro-jet belt hole should be upwards and the tail is blocked. Then use a pump to absorb water and extrude. The water inlet is wrapped with gauze (filter screen) to prevent the holes from being blocked. In case of blockage, untie the tail end and rinse it with water for one minute. You can also pat the tube wall gently with your hands and other tools. 3. In the first use, according to your pump pressure, the working length of the micro-spray belt, first open the switch, it is best to open several switches, to prevent the pressure is too large to cause the micro-spray belt blasting. Turn off a few switches if the pressure isn't enough. You'll know how many switches to turn on the next time you use them. If that piece of water is tested, switch on first when changing the piece, and then turn off all the switches of the good piece to prevent blasting caused by improper use. 4. When changing the season, the micro spray belt should be pumped and extruded with water pump, washed, rolled, and put in the shade to prevent rats and other things from biting, so as to be used again next time.

First, save water and labor, increase production and income. Because during irrigation, water does not move in the air, does not wet the leaf surface, and does not evaporate the soil surface outside the effective wetting area, so the amount of water directly lost to evaporation is the least; It is easy to control the amount of water, surface runoff and deep soil leakage will not occur. Therefore, water can be saved by 35-75% compared with sprinkler irrigation. It opens up a new way to realize water conservancy in mountainous areas with few water sources and lack of water. Due to insufficient water supply among plants, weeds are not easy to grow, so the interference between crops and weeds competing for nutrients is greatly reduced, reducing weeding labor. Because the root area of crops can maintain the best water supply state and fertilizer supply state, it can greatly increase production. Second, the cost of drip irrigation system is relatively high. Due to the influence of the precipitation of impurities and minerals, riveting tube dripper will be blocked; The uniformity of drip irrigation is not easy to guarantee. These are all obstacles to the large-scale promotion of drip irrigation technology at present. Currently, it is generally used for economic crops such as vegetables, fruits, tea, flowers, medicinal materials, etc. II. Difference between drip irrigation and microspray irrigation (1) drip irrigation technology: refers to the irrigation water with a certain low pressure, which is transported to the last stage pipeline in the facility and the dripper installed on it through the low pressure transmission and water distribution pipeline, drip evenly and accurately into the soil surface near the root area of the crop or the soil layer where the root system of the crop is located with a small flow. Drip irrigation technology belongs to local irrigation method. (2) microspray irrigation technology: It uses tiny sprinklers, with the aid of transporting and distributing pipes to the last-stage pipelines in the facility and the micro sprinklers installed on it, irrigation methods and techniques for spraying pressure water evenly and accurately on the branches and leaves of each plant or on the soil surface around the root system of the plant. Microspray irrigation technology can be partial irrigation or comprehensive irrigation. III. Sprinkler irrigation automatic fertilization technology and advantages Irrigation and fertilization technology, irrigation and fertilization is an advanced agricultural technology that combines fertilization and irrigation. It uses solid or liquid fertilizer together through pressure irrigation system, therefore, irrigation water containing crop nutrition needs is generated. 1. Save water and fertilizer, and improve fertilizer utilization rate. Irrigation and fertilization use a little more water except for surface irrigation. In facility cultivation, drip irrigation and micro irrigation can save water by 30%-40%. Compared with ordinary fertilization, irrigation fertilization has the advantages of timely fertilizer supply, easy nutrient absorption by crops, fertilizer The characteristics of high utilization rate can generally save 30%-50% of chemical fertilizer and increase production by 10%. 2. Simplify field fertilization and reduce fertilization Labor.
