Our country is an agricultural country with thousands of years of farming civilization. The evolution of farming in these thousands of years is also a history of the evolution of irrigation methods and irrigation tools.

As far as irrigation methods are concerned, before irrigation technology is perfected, irrigation is commonly used. Flood irrigation; . However. Flood irrigation; Not only time-consuming and laborious, but also easy to cause land salinization. With the development of irrigation technology, irrigation is now widely used. Drip irrigation; And; Spray irrigation ” .

Drip irrigation technology refers to the irrigation water of a certain low pressure is transported to the last stage of the pipeline in the facility and the drip head installed on it through the low-pressure water delivery and distribution pipeline. In a small flow, drop by drop evenly and accurately into the soil surface near the root zone of the crop, or into the soil layer where the root system of the crop resides. Drip irrigation technology belongs to local irrigation.

The advantages of drip irrigation technology can be summarized as one. Province; The word. Firstly, it saves water. During the growing period, it saves 40 % water compared with conventional ground irrigation. 50%. Second, save fertilizer. Water-soluble special fertilizer is applied near the roots of crops with water, which is easy to be absorbed by crops. It improves the utilization rate of fertilizer, and can save 20%~40% of fertilizer on average. It also saves land. By eliminating channels, drip irrigation saves 5 to 7 percent of farmland. It can be seen that drip irrigation technology not only saves water and energy, but also contributes to the sustainable development of natural resources.

Micro-sprinkler irrigation technology is to use tiny sprinkler heads to transport to the last stage of the pipeline in the facility through the water delivery and distribution pipeline and the micro-sprinkler installed on it, to evenly and accurately spray the pressure water on the branches and leaves of each plant or the soil surface around the plant roots. Micro-sprinkler irrigation technology can be local irrigation, but also can carry out comprehensive irrigation.
