Problems solved by technology

[0003] Our country started late in the research and application of soilless cultivation technology. At present, substrate cultivation is the most popularized method in soilless cultivation. It fixes the root system of crops in an organic or inorganic substrate, through drip irrigation or trickle flow. The method of irrigation supplies crop nutrition. The current cultivation substrate has poor water and fertilizer retention effect, and nutrients are easily lost with water flow, which not only indirectly increases the cost, but also pollutes the environment. It needs to be solved urgently.

Abstract

The invention discloses a low-cost soilless culture substrate special for vegetables. The raw materials comprise, by weight, 120-130 parts of organic nutrients, 4-10 parts of coconut shell powder, 2-8parts of kieselguhr, 2-8 parts of zeolite powder, 2-6 parts of humic acid, 1-5 parts of calcined kaolin, 1-2 parts of an EM microbial agent and 2-6 parts of a whey protein compound. The whey proteincompound is prepared through the following processes that whey protein is dissolved into water, the pH value is adjusted to range from 9.5 to 10.5, the temperature is adjusted, single epoxy terminatedpolysiloxane is added in the stirring state, stirring continues to be conducted, microwave processing is conducted, distillation is conducted to remove water, freeze drying is conducted, and the wheyprotein compound is obtained. Accordingly, the cost is low, the nutrients are extremely rich, the water and nutrient retention effect is good, the nutrients are not prone to losing, organic agricultural waste is fermented with beneficial microorganisms, the organic agricultural wastes are effectively and circularly utilized, and meanwhile the raw materials can be naturally degraded, and the environment is not contaminated.

Description

technical field [0001] The invention relates to the technical field of soilless culture substrates, in particular to a special soilless culture substrate for vegetables with low cost. Background technique [0002] Soilless cultivation refers to a cultivation method that uses substrate or nutrient solution to irrigate without using natural soil. It is mainly applied to vegetables. It is a high-yield, high-quality advanced technology that saves water, fertilizer and labor. At present, soilless cultivation technology has App development in more than 100 countries around the world. [0003] Our country started late in the research and application of soilless cultivation technology. At present, substrate cultivation is the most popularized method in soilless cultivation. It fixes the root system of crops in an organic or inorganic substrate, through drip irrigation or trickle flow. The method of irrigation supplies crop nutrition, the current cultivation substrate has poor water...
