Soilless vegetable hydroculture rack

Abstract

The invention discloses a multi-layer soilless vegetable hydroculture rack. The multi-layer soilless vegetable hydroculture rack comprises multiple layers of vegetable culture mediums spaced in an up-down manner, a liquid storage pool, a liquid distributor and a water pump. Culture liquid in the liquid storage pool is conveyed into the liquid distributor at the top by the water pump through a conveying pipe, flows into opposite vegetable hydroculture containers through overflow pipes, flows into lower vegetable hydroculture containers through overflow holes of upper vegetable hydroculture containers, and returns to the liquid storage pool through overflow holes of lowest vegetable hydroculture containers. Due to the adoption of a stereo mode of the multiple layers of culture mediums for soilless vegetable hydroculture, fertilizer can be fully utilized and the land resources are greatly saved; and particularly, the culture liquid adopts an open hierarchical flowing mode, so that the problem of high possibility of corrosion for the fixed culture liquid is solved, pathogenic bacteria can be more effectively prevented being bred, the culture liquid in the vegetable hydroculture containers can be quantitatively controlled, the vegetable growth is better facilitated, and the yield is increased by multiple times in comparison with the conventional planting method.

Description

technical field [0001] The invention relates to a shelf for growing vegetables, in particular to a soilless hydroponic vegetable shelf. Background technique [0002] China Patent Office published the application (patent) No. CN201010135324.8 on October 5, 2011, and the patent name is Soilless Cultivation - Hydroponic Combined Mini Vegetable Garden. The invention relates to the field of vegetable planting and is a kind of Invented technology for conveniently obtaining pollution-free vegetables. The technical scheme adopted by the present invention to solve the technical problem is: select specific leaves and bud vegetable varieties, and place them in specially designed double-layer seedling trays. The middle and upper layer of the seedling tray is a matrix layer containing slow-release fertilizer, the middle is an upper seedling tray grid, and the lower layer is a lower seedling tray water storage tray. The seedling trays are sterilized, dried and sealed for later use. Whe...

AI Technical Summary

Problems solved by technology

The above-mentioned patent documents have the following defects: the one is that the regular artificial water spraying method is mainly used, and if it is put into large-scale production operations, a large amount of manpower is required, which virtually increases the cost; The substrate layer, the middle is the upper seedling tray grid, and the lower layer is the lower seedling tray water storage tray. This structure is reasonable enough, too complicated, and the use of seedling trays needs to be sterilized, dried and sealed for later use, invisible The production cost is increased; the third is that the culture medium in the vegetable hydroponic vessel cannot be accurately quantitatively controlled. In the process of artificially adding liquid, there will be too much or overwater, which is not conducive to the survival and growth of vegetables.

The above-mentioned patent documents have the following defects: although the liquid circulation system is also adopted, due to the closed liquid supply mode, not only it is easy to breed bacteria, but also because the culture medium cannot fully contact with the air, even though it is also circulating, the oxygen cannot be fully dissolved. Into the culture solution, it is not conducive to enhancing the vitality of the vegetable root system, especially the way of planting with openings on the cultivation pipe network, and the cultivation pipe network of the cultivation support forms a support slope, which is not only not conducive to the survival and growth of vegetables, but also the device It is too bulky and occupies a relatively large area, so that the air resources are not fully utilized

In addition, the structure is only for home use and cannot be mass-produced
