Outdoor three-dimensional soilless culture apparatus and culture method by using outdoor three-dimensional soilless culture apparatus

Abstract

The embodiment of the invention discloses outdoor three-dimensional soilless culture apparatus. The apparatus comprises a culture device, a heat preservation device and a water supply atomization device; the culture device comprises a barrel-shaped culture frame, a base and a supporting column; the barrel-shaped culture frame is slidably connected with the base; the supporting column is arranged in the barrel-shaped culture frame; the top end of the supporting column is connected with the barrel-shaped culture frame; the inner side wall of the barrel-shaped culture frame is provided with a plurality of annular culture discs; the heat preservation device comprises a heat preservation film support and a heat preservation film; the heat preservation film covers the heat preservation film support; the bottom of the heat preservation film is fixed with the base; the water supply atomization device comprises a liquid conveying pipe and high-pressure atomizing nozzles; the liquid conveying pipe is arranged inside the supporting column; the liquid conveying pipe is connected with a plurality of the high-pressure atomizing nozzles; and the high-pressure atomizing nozzles spray a liquid to the annular culture discs. According to the invention, the problems of large occupied space and low culture solution utilization rate in existing soilless culture processes are solved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to an outdoor three-dimensional soilless cultivation device and a cultivation method thereof. Background technique [0002] Soilless cultivation uses peat or forest humus, vermiculite and other light materials as the seedling substrate to fix the plants, so that the roots of the plants can directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding to form seedlings at one time. For the cells, one seed is sown in one cell, and one seedling is planted in one cell. The root system of the seedlings and the substrate are intertwined with each other. [0003] The traditional seedling tray planting needs to occupy a large area, the space utilization rate is very low, and the cultivation of seedlings requires a large amount of manual labor. The seedlings are fixed in the seedling tray and cannot be moved. The growth of the see...
