Abstract

The invention relates to the soiless culture field and in particular relates to a soiless culture nutrient solution; every liter of water comprises the following components by weight: major constituents consisting of 900mg-2200mg of much EM (Effective Microorganisms) probiotics liquid, 900mg-2200mg of brown sugar, 900mg-1000mg of calcium nitrate tetrahydrate, 700mg-900mg of potassium nitrate, 150mg-220mg of ammonium dihydrogen phosphate and 300mg-500mg of magnesium sulfate heptahydrate; micro constituents consisting of 20mg-25mg of EDTA (Ethylene Diamine Tetraacetic Acid) chelated iron, 2mg-3mg of boric acid, 2mg-3mg of manganese sulfate monohydrate, 0.1mg-0.5mg of zinc sulfate heptahydrate, 0.01mg-0.1mg of copper sulfate and 0.01mg-0.08mg of ammonium molybdate tetrahydrate. The soiless culture nutrient solution provided by the invention can be used for improvising the immunity of the soiless culture nutrient solution for resisting plant diseases and insect pests of the crops.

Description

technical field [0001] The invention relates to the field of soilless cultivation, in particular to a nutrient solution 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 solution widely used in the prior art is mainly inorgani...
