Soilless culture medium for vegetables

Abstract

The invention relates to a soilless culture medium and particularly relates to a soilless culture medium for vegetables. A preparation method of the soilless culture medium is characterized by comprising the following steps: uniformly mixing solid materials to obtain a solid medium; spraying a nutrient solution to the solid medium and uniformly mixing to obtain materials, placing the materials at 15-30 DEG C for 13-15 days, and naturally fermenting to obtain the soilless culture medium, wherein the solid materials comprise the following components in parts by weight: 2-3 parts of thoroughly decomposed furfural residues, 2-3 parts of thoroughly decomposed corn stalks, 0.5-1 part of perlite, 1-2 parts of vermiculite, 2-3 parts of furnace clinker, and a ratio of the nutrition solution to the substrate is (1-2) to 50. According to the soilless culture medium of the vegetables disclosed by the invention, the raw materials and the method are unique, the yield of the vegetables can be increased, the amount of pesticides can be reduced, the resource cyclic utilization is realized, and the production cost is lowered.

Description

technical field

[0001] The invention relates to a soilless cultivation substrate, in particular to a soilless cultivation substrate for vegetables. Background technique

[0002] The soilless cultivation substrate can artificially create a good root system environment, which can fully meet the needs of crops for mineral nutrition and other environmental conditions. Traditional soilless cultivation substrates mostly use peat and perlite as basic materials, and are mixed with vermiculite, stone sand, stone grains, foam plastics, fermented and carbonized plant straws and other materials through automated processes. The current development of cultivation substrates mainly has the following quantitative problems: on the one hand, peat, as a non-renewable resource, is bound to destroy the wetland environment and even the entire ecological environment due to over-exploitation, and the price is also increasing year by year. On the other hand, there are various obstacles in the culti...
