Stereoscopic circulating-type aeroponic cultivation system suitable for root vegetables

Abstract

The invention discloses a stereoscopic circulating-type aeroponic cultivation system suitable for root vegetables. The stereoscopic circulating-type aeroponic cultivation system comprises a support track, multiple groups of colonization cylinders, a cultivation box, a funnel-shaped cover body, an outlet port, an exhaust fan, a nutrient solution spray assembly and a controller, wherein the supporttrack comprises a spiral track and a U-shaped track; the multiple groups of colonization cylinders are sequentially arranged on the support track in a sliding manner; the cultivation box is horizontally arranged on the ground; the U-shaped track is arranged in an opening of a spray box at the upper half part of the cultivation box; a flow guide groove is arranged in the bottom of the spiral track;the funnel-shaped cover body covers the spiral track; multiple positioning plates are detachably embedded into the opening of the spray box; and the nutrient solution spray assembly comprises a liquid supply pipe I, a liquid supply pipe II, multiple automation nozzles I, multiple rectangular circulating slide rails and multiple automation nozzles II. According to the stereoscopic circulating-typeaeroponic cultivation system suitable for the root vegetables disclosed by the invention, an existing non-uniform large-area and large-flow spray process is replaced with a uniform small-area and small-flow spray process.

Description

Technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a three-dimensional circulating aerosol cultivation system suitable for root vegetables. Background technique [0002] Aerosol cultivation is a new type of cultivation method. It is a soilless cultivation technique that uses a spray device to atomize the nutrient solution into small droplets and spray it directly onto the roots of plants to provide the water and nutrients needed for plant growth. The crops are hung in a closed cultivation device (trough, box or bed), and the root system is exposed inside the cultivation device. The nutrient solution is atomized by the spray device and sprayed onto the root surface to reduce the nitrate content of cultivated plants. It can double the yield of crops. It is an agricultural high-tech that does not use soil or substrate to cultivate plants. Because it replaces the soil environment with the artificially created crop root enviro...

AI Technical Summary

Problems solved by technology

[0003] Although aerosol cultivation has such huge advantages, due to the current aerosol cultivation methods and facilities, it is necessary to perform intermittent large-scale uniform spraying of scattered large-area plant roots every few minutes, and the spray volume and spray area of ​​each time Large, poor uniformity and high energy consumption

The existing aerosol cultivation equipment is not suitable for large-scale promotion, and is only suitable for the cultivation of small-scale virus-free seed potatoes, etc.
