Problems solved by technology

[0002] Vegetables are leafy vegetables with fat and tender leaves and petioles. There are many varieties of vegetables, rich in nutrients, including chlorophyll, carotenoids, inorganic salts, vitamins, etc. In addition, vegetables also have strong antioxidant capacity, so Vegetables occupy an important position in people's daily life and agriculture; with the improvement of the quality of life, people pursue vegetables such as nutrition and pollution-free vegetables, and the cultivation of vegetables

Abstract

The invention provides a soilless culture nutrient solution and a preparation method thereof. The soilless culture nutrient solution is prepared by compounding mother liquor A, mother liquor B and mother liquor C; the mother liquor A comprises urea, calcium nitrate, monopotassium phosphate, magnesium sulfate, calcium chloride, ferric trichloride, borax, fresh agaric, corn straw and oysters; the mother liquor B comprises manganese sulfate, zinc sulfate, calcium nitrate tetrahydrate, potassium nitrate, diammonium hydrogen phosphate and ammonium nitrate; the mother liquor C comprises monopotassium phosphate, potassium sulfate, magnesium sulfate heptahydrate, red rice fermentation liquor and barley leaching liquor; the soilless culture nutrient solution disclosed by the invention is green andpollution-free, does not contain any harmful substances, is harmless to human bodies, has higher content of main nutrient components than soil-cultured vegetables, can reduce heavy metal pollution, and has very important significance in the aspect of hydroponic vegetables.

Description

technical field [0001] The invention relates to the field of crop nutrients, in particular to a soilless culture nutrient solution and a preparation method thereof. Background technique [0002] Vegetables are leafy vegetables with fat and tender leaves and petioles. There are many varieties of vegetables, rich in nutrients, including chlorophyll, carotenoids, inorganic salts, vitamins, etc. In addition, vegetables also have strong antioxidant capacity, so Vegetables occupy an important position in people's daily life and agriculture; with the improvement of the quality of life, people pursue vegetables such as nutrition and pollution-free vegetables, and the cultivation of vegetables in our country has changed from soil cultivation to greenhouse cultivation to soilless nutrition. From substrate cultivation to soilless nutrient solution cultivation, the nutrient solution cultivation technology in my country is still in the research stage at present, and there is still a certai...
