Problems solved by technology

However, most of the existing soilless culture fertilizers so far use water as the liquid phase carrier and add a large amount, medium amount or trace elements, but do not consider from the perspective of comprehensive utilization at all. There is no related report on the soilless culture solution made from the nutrients needed for the growth of crops

Abstract

The invention belongs to the technical field of soilless culture, and particularly relates to a soilless culture solution and a preparation method thereof. The soilless culture solution is prepared from, by weight, 20,000-60,000 parts of straw organic liquid, 0.1-0.5 part of a plant growth regulator, 2-5 parts of EM probiotic liquid, 5-10 parts of antiseptic bactericidal substances, 20-50 parts of urea, 10-40 parts of potassium nitrate, 10-40 parts of monopotassium phosphate, 1-5 parts of magnesium sulfate heptahydrate, 0.1-0.5 part of chalcanthite, 0.1-0.5 part of manganese chloride tetrahydrate, 1-3 parts of ethlene diamine tetraacetic acid ferric sodium salt, 0.5-1.5 parts of boric acid, 0.5-1 part of ammonium molybdate tetrahydrate and 0-10 parts of a pH regulator. According to the soilless culture solution, the straw organic liquid is adopted as a liquid phase carrier, and the soilless culture solution is low in production cost, high in nutrient element content and wide in application range; the preparation method is simple and reasonable and promotes industrial production.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a soilless cultivation liquid and a preparation method thereof. Background technique [0002] The so-called soilless culture (soilless culture) refers to the cultivation of crops without natural soil, but the cultivation of crops in nutrient solution or substrate, this nutrient solution can replace the natural soil to provide water, nutrients, oxygen, temperature to the crops, so that the crops can grow normally. Grow and complete the entire life cycle. Due to the advantages of soilless cultivation not limited by land conditions, low labor intensity, significantly reduced pests and diseases, high quality and high yield, and convenient factory production, it has attracted more and more attention. At present, soilless cultivation is developing rapidly in our country. Numerous scientific research institutes and production units have conducted a large number...
