Preparation method of soilless culture substrate for improving quality of spinach

Abstract

The invention discloses a preparation method of a soilless culture substrate for improving the quality of spinach. The method comprises the following steps of mixing acrylic acid and a sodium hydroxide solution, conducting heating stirring, adding acrylamide to continue stirring evenly, adding wool protein and a compound adsorption slow release agent, and conducting heating stirring, filtering anddrying to obtain a prefabricated material; evenly mixing silkworm excrement, puffed soybean meal and the prefabricated material, and conducting disinfection to obtain the soilless culture substrate for improving the quality of the spinach. The preparation process of the compound adsorption slow release agent comprises the following steps of soaking vermiculite in a sodium hypochlorite solution, conducting standing and washing, adding bamboo charcoal powder, sawdust and rice husks for even mixing and grinding, and obtaining the compound adsorption slow release agent. The obtained soilless culture substrate is good in water and fertilizer retention effect, the yield of the spinach is significantly increased, the quality of the spinach is significantly improved, the culture method is convenient to operate, the adaptability is high, the soil-borne diseases are eliminated, the resource waste is reduced, the economic benefits are increased, and the problems can be solved that traditional soilless culture is high in production cost and causes pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation substrates, in particular to a method for preparing soilless cultivation substrates for improving the quality of spinach. Background technique [0002] With the continuous improvement of living standards, people's requirements for vegetable quality are also increasing. While increasing the yield of vegetables, the quality of vegetables should also be continuously improved. Soilless cultivation has become the preferred vegetable cultivation method because of its advantages of fertilizer saving, water saving, labor saving, drug saving, high yield, high quality and cleanliness, especially the organic substrate soilless cultivation method, which is rich in trace elements. It is a stable, strong buffering medium with a good root growth environment. The use of organic substrate soilless cultivation method can continuously increase the yield of vegetables and improve the quality of vegetabl...

Problems solved by technology

[0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a soilless culture substrate for improving the quality of spinach. The obtained soilless culture substrate has a good effect of water and fertilizer retention, is mainly composed of organic matter, and is compounded with organic fertilizers and minerals. Significantly improve the yield and quality of spinach. The cultivation method is easy to operate and widely adaptable. It eliminates soil-borne diseases, reduces waste of resources, improves economic benefits, and can overcome the problems of high production costs and environmental pollution caused by traditional soilless cultivation.
