Abstract

The invention discloses a vegetable soilless culture nutrient solution and a manufacturing method thereof. The invention is characterized in that every liter of water contains 5-7 mg/L potassium nitrate, 7-9 mg/L ammonium nitrate, 4-6 mg/L potassium dihydrogen phosphate, 2-4 mg/L ammonium dihydrogen phosphate, 0.5-0.7 mg/L disodium edetate, 0.2-0.4 mg/L magnesium sulfate, 0.04-0.07 mg/L iron chelate, 0.06-0.09 mg/L minor element and 2-4 mg/L boric acid. The rotten cottonseed hull contains abundant organic matters, and has certain actions of the slow-release controlled-release fertilizer. The formula is reasonable, and the pH value is approximate to neutrality. The vegetable soilless culture nutrient solution provides nutritive elements required by vegetable growth, and the ion concentration can not easily change. The vegetable soilless culture nutrient solution can effectively fix the plant root system, and has the advantages of simple production operation, low cost, high vegetable yield and good quality.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a nutrient solution for soilless cultivation of vegetables and a preparation method thereof. Background technique [0002] Vegetables refer to plants other than food that can be cooked and cooked into food. They are one of the indispensable foods in people's daily diet. Vegetables can provide a variety of vitamins and minerals necessary for the human body. 90% of vitamin C and 60% of vitamin A are from vegetables. In addition, there are a variety of phytochemicals in vegetables, which are recognized as effective ingredients for health. Due to the high planting efficiency, vegetable planting has become a rapidly developing new industry in rural areas of our country. With the gradual expansion of vegetable production scale and continuous improvement of planting level in our country, as well as the increasingly high quality requirements of consumers for v...
