Problems solved by technology

[0003] In the process of fertilizing chives in the process of soilless cultivation of chives, nutrient solution is indispensable. The existing nutrient solution of chives cannot prevent the root of chives from rotting for a long time, and it is necessary to continuously apply nutrient solution, Moreover, chives are easy to breed diseases and insect pests such as chives maggots, the growth rate is slow, and the yield is low. It is necessary to apply a large amount of pesticides, pollute the environment, and affect the quality of chives. The soluble sugar content, crude fiber content, and soluble protein content of chives are low. The content of salt and nitrate is high, and nitrate will be converted into nitrite in the human body. This nitrite is a carcinogen that affects people's life and health. The plant height, leaf length, leaf width, and pseudostem thickness of chives , the number of leaves and the vitality of the root system did not increase significantly, and the vitamins of leeks were higher than those of leeks

Abstract

The invention discloses a water culture nutrient solution special for hotbed chives and preparation method of water culture nutrient solution. The water culture nutrient solution comprises urea, calcium nitrate, ferrous sulfate, magnesium sulfate, ammonium dihydrogen phosphate, potassium nitrate, boric acid, manganese sulfate, copper sulfate, zinc sulfate, a metabolic regulator, sodium sulfate, vitamins, a rooting agent, a bactericide and an appropriate amount of pH value regulation acid and purified water. According to the used metabolic regulator, the nutrient solution for hotbed chives is capable of promoting metabolic transformation of nitrate absorbed into Chinese chives to produce subsequent amino acids and proteins, so that accumulation of nutrients is facilitated, the flavor quality of the Chinese chives is improved, the content of the nitrate in the hotbed chives can be reduced, and the human health safety is protected; due to the added sulfur, the growth index of the Chinesechives is improved, the plant height, leaf length, pseudostem diameter, leaf width and number of leaves of the hotbed chives are improved, the root vitality of the hotbed chives is improved, and the yield and quality of the hotbed chives are improved. The nutrient solution special for hotbed chives is capable of preventing root rot of the hotbed chives for a long time.

Description

Technical field: [0001] The invention relates to the field of Chinese chive nutrient solution, in particular to a special hydroponic nutrient solution for Chinese chive and a preparation method thereof. Background technique: [0002] Vegetable hydroponic production has the characteristics of high yield, early maturity, water saving, light disease, and no pollution. The cost of nutrient solution used to produce 1 kg of vegetables is only a few cents, and urban residents can also use balconies and roofs for production. The hydroponic technology of several kinds of vegetables and watermelon is introduced now. Soilless cultivation does not have the buffer of soil and the action of microorganisms. The substrate and nutrient solution are the root environment for plants to survive. [0003] In the process of fertilizing chives in the process of soilless cultivation of chives, nutrient solution is indispensable. The existing nutrient solution of chives cannot prevent the root of ch...
