Tower-type stereoscopic cultivation frame and tower-type stereoscopic cultivation device

Abstract

The invention discloses a tower-type stereoscopic cultivation frame and a tower-type stereoscopic cultivation device. The tower-type stereoscopic cultivation frame comprises at least two vertical supporting tubes; a plurality of transverse planting tubes are arranged from top to bottom among the vertical supporting tubes; the transverse planting tubes are of tubular body structures with openings along the axial direction. The bottom portion of the transverse planning tubes is covered by an arc plate; the inner side of the arc surface of the arc plate forms a drainage channel with the inner sides of the arc surfaces of the bottom portions of the transverse planting tubes; and the drainage channel is communicated with the drain holes reserved on the vertical supporting tubes. The transverse planting tubes incline a certain angle relative to the horizon so as to facilitate drainage of redundant irrigation water and nutrient solution in the tubes. Stereoscopic cultivation systems include a fertigation system and a water storage system except the stereoscopic cultivation frame. Operation cost of stereoscopic cultivation is greatly reduced; the tower-type stereoscopic cultivation frame and the tower-type stereoscopic cultivation device are easy to accommodate, low in cost and capable of facilitating promotion and application of the stereoscopic cultivation.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation and relates to a three-dimensional cultivation device. Background technique [0002] Substrate cultivation is an intensive modern agricultural technology, a new energy-saving and water-saving production method, which can give full play to the effectiveness of existing protected facilities and the advantages of local natural resources. It is an agricultural high-tech that does not use soil to cultivate plants. Because it replaces the soil environment with the artificially created crop root environment, it can effectively solve the contradictions of water, air and nutrient supply that are difficult to solve in traditional soil cultivation, and make the crop root system Under the most suitable environmental conditions, the potential of increasing crop production can be fully exerted, and the purpose of increasing yield per unit area, advancing or delaying the vegetable supply period,...

AI Technical Summary

Problems solved by technology

[0003] At present, it is known that the three-dimensional cultivation technology uses nutrient solution, and the nutrient solution must be sterilized by ultraviolet light and ozone, recycled and disposed of before being reused. If the nutrient solution is not thoroughly sterilized, the recycled nutrient solution can prevent Aobo root disease in the entire greenhouse. Infect other healthy plants, and in severe cases, a large number of crops will die. If the nutrient solution is not recycled and discharged directly, the discharged waste liquid will pollute the soil, surface water and groundwater, and the waste liquid directly discharged into the river will cause rivers or lakes. Eutrophication of water, while wasting a lot of water resources
