       Agricultural modernization develops with the development of agricultural technology modernization, so promoting the application of science and technology in the field of agriculture is the most important content at present. In the actual agricultural production, irrigation bears the important responsibility of improving soil environmental conditions, meeting crop growth needs and ensuring the safe growth of crops. The use of intelligent irrigation system to achieve automated and intelligent irrigation, not only can effectively save labor and reduce labor costs, but also can achieve efficient water-saving irrigation and precision irrigation, accelerate the pace of agricultural irrigation modernization in China.

 

       Drip irrigation equipment is an irrigation system that drips water slowly to the soil at low pressure through drippers on trunks, branches and capillaries, and supplies filtered water, fertilizers or other chemicals directly to the soil. It does not spray water or channel water, only let the water drip out slowly, and under the action of gravity and capillaries into Shilou. Dripping water near the root of a crop often keeps the soil in the main root zone of the crop in the optimum water condition. This is an advanced irrigation method.

 

       Compared with surface irrigation and sprinkler irrigation, drip irrigation has the following characteristics:

 

       1. Provide water and labor, increase production and income. Because water does not move in the air, does not wet the leaf surface, and does not evaporate on the soil surface beyond the effective wetting area, the amount of water directly consumed in the evaporation is the least; it is easy to control the amount of water, and does not cause surface runoff and deep soil leakage. Therefore, it can save 35-75% of water than sprinkler irrigation. It opens up a new way for realizing water conservation in mountainous areas with little or no water resources. Because of insufficient water supply between plants, weeds are not easy to grow, so the interference of competing for nutrients between crops and weeds is greatly reduced, and the weeding use is reduced. Because the crop root zone can maintain the best water supply and fertilizer supply, it can increase yield.

 

       2. The cost of drip irrigation system is high. Because of the influence of impurities and minerals precipitation, the capillary emitter will be blocked, and the uniformity of drip irrigation is not easy to guarantee. These are the obstacles to the large-scale promotion of drip irrigation technology. At present, it is commonly used in tea, flowers and other cash crops.
