Nutrient solution for soilless cultivation of vegetables

Abstract

The invention provides a nutrient solution for soil-free cultivation of vegetables. The nutrient solution comprises a mother solution A, a mother solution B and a mother solution C, wherein the mother solution A is prepared from potassium sulfate, ammonium dihydrogen phosphate, magnesium sulfate, urea and calcium nitrate in a weight ratio; the mother solution B is prepared from potassium nitrate and ammonium nitrate in a weight ratio; the mother solution C is prepared from EDTA, ferrous sulfate, boric acid, manganese sulfate, zinc sulfate, copper sulfate and ammonium molybdate in a weight ratio; water for preparing each mother solution is local tap water. The nutrient solution is prepared by mixing the mother liquor A and the mother liquor C according to a weight ratio being 5: 1 or mixing the mother liquor B and the mother liquor C according to a weight ratio being 5: 1 and alternately applied, the mother liquor A is not mixed with the mother liquor B in application, and the mother liquor C is diluted by 1500-1800 times to be applied as vegetable foliage fertilizer. The nutrient solution can meet the requirements for normal growth and development of the soil-free cultivated vegetable and various nutrients, immunity of the vegetables can be improved, the occurrences of pests and diseases are reduced, the preferable growth effects of vegetables are achieved, both yield and quality are increased and thus the income and benefits of vegetable growers are increased.

Description

Technical field: [0001] The invention relates to the field of soilless cultivation of crops, in particular to a nutrient solution for soilless cultivation of vegetables. Background technique [0002] In recent years, my country's soilless cultivation technology has developed rapidly. In soilless culture, crops rely entirely on nutrient solution to provide the nutrients and water needed for crop growth. Whether each nutrient and nutrient element meets the requirements of different growth stages during the growth of crops depends on the formula and concentration of the nutrient solution. [0003] Nutrient solution is the core issue of soilless culture production. In soilless cultivation of vegetables, the nutrient solution must have various nutrients needed to maintain their normal growth and development. Under the existing technology, the nutrient solution can only provide the most basic nutritional requirements for vegetables grown without soil, and the quality of vegetab...

AI Technical Summary

Problems solved by technology

Under the existing technology, the nutrient solution can only provide the most basic nutritional requirements for vegetables grown without soil, and the quality of vegetables cannot be effectively guaranteed. Especially in continuous cropping, the resistance of vegetables to diseases and insect pests will affect the yield and quality of vegetables and reduce Economic Benefits of Vegetable Farmers
