Description

Aeroponic plant factory rack for growth of big-leaf pasture

Technical Field

The invention relates to the technical field of plant cultivation, in particular to an aerial fog cultivation plant factory rack for growth of large-leaf pasture.

Background

Aerial fog cultivation is a feasible form for solving the moisture contradiction of root systems in all soilless cultivation technologies, and meanwhile, the aerial fog cultivation is easy to automatically control and carry out three-dimensional cultivation, so that the utilization rate of greenhouse space is improved. The aerial fog cultivation is a novel cultivation mode, and is a soilless cultivation technology which atomizes nutrient solution into small fog drops by utilizing an atomizing device and directly sprays the small fog drops to a plant root system to provide water and nutrients required by plant growth. Crops are hung in a closed cultivation device (a groove, a box or a bed), the root system is exposed in the cultivation device, and the nutrient solution is atomized by the atomizing device and then sprayed to the surface of the root system, so that the content of nitrate in the cultivated plants is reduced. The method can increase the crop yield by times, is an agricultural high and new technology for cultivating plants without soil or substrates, replaces the soil environment with the artificial creation of the crop root system environment, can effectively solve the contradiction of water, air and nutrient supply which is difficult to solve in the traditional soil cultivation, enables the crop root system to be in the optimum environment condition, thereby exerting the growth potential of the crops and greatly improving the plant growth amount and biomass.
