Soilless culture frame for vegetables

Abstract

The invention discloses a soilless culture frame for vegetables. The soilless culture frame for the vegetables comprises four vertical columns and a nutrient solution tank, wherein liquid storage troughs are uniformly fixed between the four vertical columns; planting plates are mounted above the liquid storage troughs; light supplementing lamps are fixed on the lower surfaces of the liquid storage troughs; the nutrient solution tank is located among the four vertical columns; a nutrition supplementing box and a controller are mounted on the upper surface of the nutrient solution tank; the controller is located on one side of the nutrition supplementing box; one side of the nutrient solution tank is communicated with a solution conveying pipe; the solution conveying pipe is communicated with a first solution guide pipe; the other side surface of the nutrient solution tank is communicated with a solution discharging pipe; the solution discharging pipe is communicated with a second solution guide pipe. The soilless culture frame for the vegetables is simple in structure; when nutrient substances are used, water resources are saved; the phenomenon that the nutrient solution in a bottom-layer device is surplus during simultaneous multilayer supplying is avoided, and the supply amount for each layer is equal, so that the service life of the device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a vegetable soilless cultivation frame. Background technique [0002] Vegetables contain many nutrients and are essential food for people's life. Traditionally, vegetables generally grow in a natural environment, requiring land, sunlight, irrigation equipment and many other equipment. Today, the supply of land is increasingly tight. Opening up a large area of ​​farmland for growing vegetables is quite a luxury for some cities, so soilless cultivation is gradually developed. The fundamental difference between soilless cultivation and conventional cultivation is that soilless cultivation refers to the use of substrates or only A cultivation method in which substrate is used for seedling cultivation and nutrient solution is used for irrigation after planting. Soilless cultivation of vegetables is the most advanced cultivation technology in the world today. In the curre...

AI Technical Summary

Problems solved by technology

[0003] Although the existing devices can be expanded on non-renewable cultivated land resources, they only have a single-layer device, and the degree of utilization is limited, and the most important thing in soilless cultivation is the nutrient solution. There are certain defects in the transportation, which will cause too much nutrient solution in some layers, and insufficient nutrient solution in some layers. After the nutrition in the nutrient solution in the device is absorbed, it is troublesome to replace the nutrient solution, and each Nutrients required for each stage are not exactly the same
