Problems solved by technology

The problem is that these soilless culture nutrient solutions only provide the most basic nutritional requirements for crops, but the immunity of the crops themselves is low, and the ability to resist diseases and insect pests is weak, resulting in a reduction in the survival and yield of the crops.

Abstract

The invention provides a preparation method of a soilless culture nutrient solution, which is characterized in that the soilless culture nutrient solution comprises the following components by weight percentage: 30-40% of EM (Effective Microorganism) solution, 10-18% of brown sugar, 5-8% of calcium nitrate terahydrate, 3-14% of potassium nitrate, 13-26% of ammonium dihydrogen phosphate, 3-9% of manganese sulfate monohydrate, 4-13% of zinc sulphate heptahydrate and 2-5% of EDTA (Ethylene Diamine Tetraacetic Acid) iron chelate. According to the method, an ecological status in the nutrient solution can be rapidly and stably occupied, and a dominant community of effective microorganisms is formed, so that reproduction of pathogenic microorganisms and invasion to crops are controlled, reproduction of harmful bacteria is inhibited, a purpose of combating the harmful bacteria with the effective microorganisms is achieved, and the resistance and the immunity of the crops are improved. Therefore, the provided soilless culture nutrient solution can improve the immunity of disease and pest resistance of the crops.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a method for assembling nutrient solutions for soilless cultivation. Background technique [0002] The nutrient supply of soilless crops depends entirely on the nutrient solution. The nutrient solution is to mix and dissolve the macronutrients and trace elements required for the growth and development of the crops in water in a certain proportion to meet the growth needs of the crops placed in the water. nutrient supply. Because this kind of cultivation method can save a lot of land use compared with soil cultivation, and in terms of crop planting and cultivation, it will be less affected by the region. Therefore, soilless cultivation technology has been widely used in crop cultivation. [0003] In soilless cultivation technology, the preparation of soilless cultivation nutrient solution is the most critical. The soilless cultivation nutrient solut...
