Soilless vegetable culture nutrient solution and preparation method

Abstract

The invention relates to the field of nutrient solutions, in particular to a soilless vegetable culture nutrient solution and a preparation method. The soilless vegetable culture nutrient solution is prepared from sodium nitrate, urea phosphate, potassium nitrate, ammonium sulfate, magnesium chloride, Fe-EDTA, boric acid, manganese chloride, zinc sulfate, copper sulfate, sodium molybdate, mixed nitrogen-fixing bacterium solution and a nostoc extracting solution. The nutrient solution is simple and convenient to prepare, comprehensive in nutrient ingredient, high in biological activity and good in homogeneity, can decompose self-toxic materials produced by vegetables, remarkably improve the resistance, yield and the quality of the vegetables.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation. Specifically relates to a nutrient solution for soilless cultivation of vegetables and a preparation method thereof. Background technique [0002] In traditional vegetable planting, due to the intensive production of the soil year after year, large-scale application of chemical fertilizers and pesticides, and frequent rainwater leaching, the chemical residues in the soil are high and the effective fertilizer efficiency is reduced, resulting in a serious imbalance in the soil ecology, resulting in the production of vegetables. Low quality, poor quality, serious physiological diseases. Moreover, the current traditional production mode has disadvantages such as cumbersome management, heavy labor, low land use efficiency, and poor economic benefits. [0003] The emerging soilless cultivation mode can effectively prevent the occurrence of soil-borne diseases because its cultivation envi...

Its operation is cumbersome and has high requirements for planters

[0004] There are many researches on the improvement and use of soilless culture nutrient solution in the present technology, such as the nutrient solution of a kind of soilless culture leafy vegetables and its preparation method that the patent number is CN200810014041.0, using calcium nitrate, potassium nitrate, sulfuric acid Ammonium, potassium dihydrogen phosphate, potassium sulfate, calcium chloride, magnesium sulfate, iron ethylenediaminetetraacetate, copper sulfate, manganese chloride, zinc sulfate, boric acid, molybdic acid, the configuration is simple, the nutrition is comprehensive, but the elements are constant, The nutrient solution itself does not have the function of regulating

Another example is that the patent No. is CN201210352920.0 a kind of plant nutrient solution for soilless cultivation of tomato, using potassium nitrate, calcium nitrate, magnesium sulfate, ammonium phosphate, potassium sulfate, potassium dihydrogen phosphate, Na2-EDTA0, Fe-EDTA , molybdic acid, manganese sulfate, sodium tetraborate, calcium superphosphate, zinc sulfate, copper sulfate, ammonium nitrate 0.00, urea, organic acid, β-cyclodextrin, vitamin B complex, chitosan, niacinamide, amino acid, caproic acid Diethylaminoethanol ester, gibberellin, water, this patent uses organic ingredients with growth-promoting effects, such as organic acids, chitosan, etc., on the basis of mineral nutrition, but the nutrient solution itself does not have biological activity, and the environment is resistant to stress poor sex

There is also a tomato soilless cultivation nutrient solution whose patent number is CN201310628017.7, which uses calcium nitrate tetrahydrate, sodium ferric diamine tetraacetate, ammonium nitrate, EM probiotic liquid, potassium nitrate, potassium magnesium phosphate, copper sulfate , manganese sulfate, boric acid, ammonium molybdate, and EDTA chelated iron, in which microbial components are added, but the pertinence is not strong, and the vegetable root metabolites in the nutrient solution cannot be effectively decomposed, and the components of the nutrient solution cannot be well fixed.

[0005] Although there are many studies on soilless culture nutrient solution, the exploration of soilless culture nutrient solution is the direction of efforts of people in the field, and there are relatively few studies on the microbial activity of soilless culture nutrient solution in the prior art
