The irrigation water source in Ningxia Plain mainly comes from the Yellow River, and the local climate is dry. After flood irrigation, the water evaporates violently, which is easy to cause land salinization. Moreover, flooding rice planting wastes a lot of water resources, which is not suitable for the water-deficient north.

The comprehensive cultivation of rice and fish here saves more than 25% water than ordinary rice, and the average income per mu reaches 3000 yuan, which is more than twice that of ordinary rice cultivation. Not only planted good food, but also planted benefits and landscapes.
