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. Datian Micro Spray 10

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. Drip Irrigation 99

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.
