Problems solved by technology

Therefore, the use of soilless cultivation is beneficial to meet its water requirements, and it can grow rapidly, but its roots are easy to rot, and the leaves are often green, but the roots are rotten, which is difficult to meet market demand.
Moreover, a large amount of nutrient solution is needed in the soilless cultivation process. If the nutrient solution in the cultivation process cannot be fully utilized, the recycling cost is relatively high, and it is easy to cause eutrophication if it is directly discharged into the water body or soil

Abstract

The invention discloses a Chinese cabbage soilless culture device capable of increasing the utilization rate of a nutrient solution. The device comprises a transparent cultivation box with an upper opening. A field planting layer, whose bottom is a hard mesh plate, is movably embedded in the opening of the transparent cultivation box. A hard water pipe, which communicates a nutrient solution and the upper surface of the filed planting layer, is throughly arranged in the field planting layer. The upper end of the hard water pipe is provided with a rotary nozzle. The device also comprises at least three telescoping cylinders for pushing the field planting layer to move up and down. In the transparent cultivation box, a first isolation layer, a stirring layer, a second isolation layer, an algae culture layer, an eggshell layer arranged on the bottom of the cultivation box, and a controller for controlling the telescoping cylinders and the motor to work are sequentially arranged. The device can fully utilize the nutrient solution and can harvest Chinese cabbage and algae at the same time.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, and more specifically, the invention relates to a soilless cultivation device and cultivation method of Shanghai greens which improve the utilization rate of nutrient solution. Background technique [0002] Shanghai Qing is a kind of Chinese cabbage. Shanghai Qing can provide the human body with vitamins and minerals needed by the human body. Frequent consumption of Shanghai Qing has great benefits for the blood vessels, skin and eyes of the human body. At the same time, Shanghai Qing has great effects on ulcers. Great inhibitory effect, the current demand for Shanghai Qing in the market is also very large. Because Shanghai Qing needs a lot of water and is afraid of stagnant water. Therefore, the soilless cultivation of Shanghai green is beneficial to meet its water requirements, and can grow rapidly, but its roots are easy to rot, and the leaves often appear green, but the root rot...
