Problems solved by technology

[0003] At present, the inorganic nutrient solution commonly used in soilless cultivation is composed of only mineral nutrients and lacks organic nutrients. The efficiency of fertilizer absorption and nutrient conversion is low, the performance of disease prevention and stress resistance is poor, and the nitrate content in the organs of planting products is too high. , basically does not meet the green food production standards and has poor safety and poor quality and taste
[0004] At present, the organic nutrient solution used in soilless cultivation is usually anaerobic fermentation liquid of nitrogen-containing cakes such as peanut cake and bean cake, and biogas slurry. The nutrient solution is not comprehensive in nutrients, and the solution is prone to corruption and odor, and the cultivated crops are prone to root rot. , dead trees, stunted growth, etc.
Whether it is an inorganic nutrient solution or a traditional organic nutrient solution, the water body is prone to produce algae, which affects the normal growth of crops, and the produced vegetables have poor taste and quality, which does not meet the standards of organic planting.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and relates to a biological-organic-inorganic composite nutrient solution and a preparation method thereof, a soilless cultivation method using organic nutrient solution carbon fertilizer, and in particular to a method using specific microorganisms and organic nutrients The preparation method of the novel soilless culture nutrient solution formed by compounding substances and mineral nutrients. Background technique [0002] Soilless cultivation is a cultivation technology that does not use natural soil, but uses nutrient solutions containing essential elements for plant growth and development to provide nutrition, so that plants can normally complete the entire life cycle. It was first applied to agricultural production in foreign countries in the 1940s. China has begun to research and apply it. In recent years, the promotion of soilless cultivation has become a hot direction to alle...
