Leaf vegetable hydroponic nutrient solution and preparation method thereof

Abstract

The invention belongs to vegetable water planting nutrient solutions, and in particular discloses a leaf vegetable water planting nutrient solution and a preparation method thereof. The leaf vegetable water planting nutrient solution is prepared from effective amounts of calcium nitrate, potassium nitrate, monopotassium phosphate, magnesium sulfate, ferrochel, sodium nitrate, boric acid, sodium molybdate, zinc sulfate, manganese sulfate and sodium chloride which are dissolved in water and are compounded together. By adopting the leaf vegetable water planting nutrient solution, the problems that conventional water planting vegetable is high in both production cost and nitrate content are solved, and the leaf vegetable water planting nutrient solution has the advantages that the nutrient solution is easy to prepare and low in cost, various biological indexes and qualities of planted water planting vegetables are remarkably prior to those of control groups, the content of nitrate meets the national standard and the standard of green pollution-free vegetables, and the like.

Description

technical field [0001] The invention belongs to a vegetable hydroponic nutrient solution, in particular to a leafy vegetable hydroponic nutrient solution and a preparation method thereof. Background technique [0002] After the adjustment of the agricultural industry structure, the facility vegetables have been greatly developed and become the main channel for farmers to increase their income. However, there are still some problems in the production of facility vegetables. For example, in order to pursue high yield and high efficiency, excessive chemical fertilizers are applied blindly, resulting in waste of water and fertilizer resources and pollution to the soil environment; continuous cropping obstacles are serious when the same crop is planted for many years, resulting in soil salinization. And the rampant occurrence of soil-borne diseases, etc., will inevitably affect the quality of vegetable products. Soilless cultivation is one of the measures to fundamentally solve t...

AI Technical Summary

Problems solved by technology

my country's soilless cultivation, including hydroponics, started relatively late, and the area of ​​soilless cultivation in the 1980s was less than 10hm 2 , but with the development of soilless cultivation technology research, its agricultural production area has also increased rapidly, and by 2005 it had exceeded 1100hm 2 , but due to the high one-time investment in its facilities and equipment, the nutrient solution management requires high technology and other factors, there are many problems in large-scale and intensive production, such as different water quality in different regions, difficult nutrient solution formula and configuration, and vegetables Hydroponics has no buffer conditions for soil crops. Soilless cultivation changes the rhizosphere environment of crops from soil to water environment or matrix environment. The composition and concentration of nutrient solution must meet the absorption and growth of vegetables, otherwise it will cause unfavorable growth due to unbalanced solution and concentration.

The document with the patent number 201210551739.2 provides a simple process, sufficient raw materials, and easy-to-implement rapeseed hydroponic nutrient solution, which solves the problem of withered and yellow leaves of rapeseed cultivated by indoor hydroponics
