technical field

The invention relates to the technical field of plant cultivation devices, in particular to a diversion cultivation device.

Background technique

Hydroponics technology can directly provide nutrients and water to roots through nutrient solution under controllable facility conditions, and produce vegetables with high yield, quality and economic value. To a certain extent, the safety problem of vegetable food has been alleviated. Especially leafy vegetables, the production cycle is short, the yield is high, and the hydroponic technology is simple, so the hydroponic technology is the most widely used in the production of leafy vegetables.

In the prior art, there are mainly two ways for the water supply and drainage of plant cultivation racks. The first one is that when water is supplied, the nutrient solution flows in from the top hydroponic layer rack, flows through each cultivation tank from top to bottom, and flows out from the bottom layer. Continuous liquid supply ensures the supply of nutrient solution. When draining water, the nutrient solution also flows through each cultivation tank from top to bottom, and finally flows out from the low-level cultivation tank. Although this method can make the components of the nutrient solution fully utilized, but When draining water, it also needs to flow through each cultivation tank, which takes a long time and affects work efficiency. Second, when water is supplied, the nutrient solution is simultaneously supplied to each cultivation tank through the water supply system. When draining, the cultivation tank is drained at the same time. , the nutrient solution process is short, the drainage time is short, but the nutrient solution flows through a short distance, and the nutrients cannot be fully utilized.
