　　(1) Sprinkler irrigation Sprinkler irrigation saves 30% more water than diffuse irrigation, and is mainly used for densely planted crops in large fields, suitable for regional control, with the advantages of increasing yields and improving the utilization rate of arable land, etc. However, it consumes more energy to operate, has a larger evaporation loss, and requires a large-capacity water source, and can only be used in the conditions of no more than three winds.

　　(2) Micro-irrigation Micro-irrigation is an advanced water-saving irrigation technology, which can only provide the required amount of water to the water-demanding parts of the crop, and convert from "watering the ground" to "watering the crop". Micro-irrigation is used in facility agriculture and cash crops, adapted to all terrain and soil, with water saving, yield effect, irrigation uniformity, at least 50% water saving than sprinkler irrigation. Micro-irrigation can easily achieve water and fertilizer integration. However, micro-irrigation on water quality and daily system maintenance requirements are high.

　　(3) Drip irrigation Drip irrigation is an irrigation technology that has emerged in recent years. Since 1996, respectively, in Beijing, Tianjin, Jiangsu, Xinjiang, fast-growing forests, fruit trees, lawns, urban greening plants to implement underground drip irrigation, have been successful. Underground drip irrigation evaporation is very small, can be completely free from the influence of the wind, can implement three-dimensional accurate positioning of water and fertilizer irrigation. The utilization rate of water is as high as 0.98, and theoretically the loss of water is negligible. Facility loss is small, free from the influence of ultraviolet radiation, not easy to aging.
