Our country has always been a big agricultural country with a farming civilization for thousands of years. The evolutionary history of farming for thousands of years is also the evolutionary history of various irrigation methods. From flood irrigation in the past, drip irrigation has begun to be used by more and more people with the development of science and technology. Irrigation is the foundation of crop growth and harvest, and the foundation of a country’s agricultural development. “In 2017, agricultural water demand decreased by 4.6 billion cubic meters compared with 2016, but still accounted for 62% of total water demand. In terms of water-saving irrigation, my country’s There is a clear gap with other countries, and there is still great potential for improving the efficiency of agricultural irrigation." The invention of water-saving irrigation technology like Israel not only created a miracle in the desert, but also made Israel's agricultural production technology famous all over the world. So in our country, what are the common irrigation methods? Which irrigation method is better?

Judging from the indicator of the actual water consumption per mu of farmland irrigation, from 439 cubic meters in 2004 to 394 cubic meters in 2015, the decline is relatively large. But from another point of view, the proportion of agricultural water used in 2017 is still estimated to be 62%, and the proportion in 2000 was 69%. The data shows that the proportion of water used in agriculture has gradually and slowly declined in recent years.

The water output of the irrigation machine can reach more than 50 cubic meters per hour. If the watering volume per mu is 20 cubic meters, it can reach more than 50 acres every day and night. The sprinkler irrigation nozzle has a low distance from the ground and a short time for water droplets to fall on the ground; it has no harm to crop seedlings and is suitable for watering needs of different crops. At the same time, the water evaporation is less, the evaporation rate is less than 5%, and the water saving effect is obvious.
Drip irrigation is currently the most water-saving irrigation mode, and the water utilization rate of drip irrigation can reach 95%. It saves 30%-50% of water than ground irrigation, and some crops can reach about 80%, and it saves 10%-20% of water than sprinkler irrigation. In addition, the evenness of the sprinklers is higher, which directly drops water to the roots of the crops, reducing evaporation and keeping the ground moist at all times.
