1. Save water and labor, increase production and income. Because during irrigation, water does not move in the air, does not wet the leaves, and does not evaporate the soil surface beyond the effective wet area, so the direct loss of water to evaporation is minimal; it is easy to control the amount of water, and it will not cause ground runoff and deep soil leakage. Therefore, it can save 35-75% of water compared with sprinkler irrigation.
It has opened up a new way to realize water conservancy in mountainous areas with few water sources and water shortages. Due to insufficient water supply between the plants, weeds are not easy to grow, so the interference between crops and weeds competing for nutrients is greatly reduced, and the labor for weeding is reduced. Since the root zone of the crops can maintain the best water supply and fertilizer supply state, it can increase the yield.
2. The drip irrigation system has higher requirements on the quality of management personnel and intensive planting of farmland, and the cost is higher than that of traditional canal irrigation, and the capillary dripper will be blocked due to the influence of the precipitation of impurities and minerals, and the uniformity of drip irrigation is not easy to guarantee. . These are all obstacles to the widespread promotion of drip irrigation technology. In order to promote the modernization and sustainable development of agriculture, my country is vigorously promoting high-efficiency water-saving irrigation technology, and the development prospect is broad.
