Features

Through irrigation measures, to meet the plant's need for water, regulate the temperature of the land and the nutrients of the soil, in order to improve land productivity. Mainly through a variety of agricultural water irrigation facilities, to meet the crop's need for water, regulate the land temperature, humidity and soil air, nutrients, to improve land productivity. It is a kind of stable and high-yield agriculture.

So all over the world, especially on the banks of large rivers, such as the Mississippi River in North America, the Amazon River in South America, the Yangtze River in Asia, Africa's Nile River Basin, have developed irrigated agriculture. China's irrigated agriculture, since ancient times is very developed. As early as the early Warring States period, that is, the construction of Dujiangyan water conservancy project, so that a large area of farmland in the Chengdu Plain is irrigated, and is still playing a role in the benefits.
