As a modern agricultural technology, soilless cultivation has received extensive attention and application in recent years due to its advantages of water saving, fertilizer saving, high yield, cleanliness and pollution-free.

Soilless cultivation can be roughly divided into hydroponics, aeroponics, substrate culture, etc.

Soilless cultivation replaces the soil environment with an artificially created crop root environment, which can effectively solve the contradiction in the supply of water, air and nutrients that is difficult to solve in traditional soil cultivation, and puts the crop roots in the most suitable environmental conditions, thereby giving full play to the crop's yield potential.
