With the popularization of smart greenhouses, especially glass greenhouses with high construction costs and long service life, more and more soilless cultivation technology is applied! Soilless cultivation technology can make full use of the limited planting space, not only limited to the surface plane, but also three-dimensional planting!
The main nutrient source of the current three-dimensional soilless culture technology is a nutrient solution, and the crops need water and fertilizer to complete the planting method of vegetable nutrient supply. Plant nutrient liquid fertilizer, which is prepared from an organic substrate dominated by industrial and agricultural waste after high temperature fermentation, can provide necessary nutrients for the growth of plants, not only can reduce environmental pollution problems at a corresponding level, but also can be used for soilless cultivation The vegetables are given sufficient organic fertilizer nutrients. It can also greatly reduce the problem of repeated cropping caused by continuous soil cropping, as well as the infestation of soil soil-borne diseases!
