Hydroponics nutrient solution for eruca sativa and preparation method of hydroponics nutrient solution

Abstract

The invention discloses a hydroponics nutrient solution for eruca sativa and a preparation method of the hydroponics nutrient solution, wherein a formula of the nutrient solution comprises the following components: 50-80mL of tofu waste water, 50-120mL of tea cake water, 20-30mL of molasses fermentation liquor, 80-100g of plant ash, 0.5-1.5mg of indole butyric acid, 0.5-1.5mg of naphthylacetic acid, 1.5-5mg of chitosan oligosaccharide, 220-250mg of ammonium nitrate, 5-8mg of sodium molybdate, 3-5mg of borax, 3-5mg of calcium nitrate, 6-10mg of ferrous sulfate, 1-3mg of manganese sulfate, 1-3mg of zinc sulfate, 1-3mg of copper sulfate and pig manure water supplemented to 1L. The hydroponics nutrient solution is prepared by the following steps: filtering waste water, heating the filtered waste water, carrying out chelation on the heated waste water and trace elements to form a complex, and regulating a pH value, the conductivity and a dissolved oxygen content finally. The hydroponics nutrient solution is beneficial to growth of the eruca sativa without spraying insecticides and applying a fertilizer any more when being used, is rich in raw material source and simple in preparation technology and has a larger popularization value.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a hydroponic nutrient solution of arugula and a preparation method thereof. Background technique [0002] arugula( Eruca sativ Mill) is also known as stinky cabbage, Northeast stinky cabbage, brassica, and piaoercai, which have high nutritional content and health value. According to analysis, every 100 grams of arugula contains 92% water, about 0.3 grams of protein, 0.1 grams of fat, and about 0.4 grams of carbohydrates. Arugula has stimulating, diuretic and stomachic effects, and arugula also has special effects on chronic cough. The seed oil of arugula has the functions of detoxification and diuresis. It can lower lung qi and treat chronic cough and frequent urination. Its tender stems and leaves contain a variety of vitamins, minerals and other nutrients. Arugula is vulnerable to pests and diseases during the planting and growth process. Flea beetle and diamo...

Problems solved by technology

[0004] At present, most of the hydroponic nutrient solutions for arugula use a combination of large amounts of elements and medium and trace elements. Although it can meet the fertilizer needs of arugula, it is still necessary to prevent and control the diseases, insect pests and viruses of arugula in hydroponic management, resulting in Chemical pollution of arugula, how to choose a suitable nutrient solution, can not only ensure the regularity of fertilizer requirements of arugula, but also repel insects and diseases in the later stage, use no or less pesticides, and truly realize the cultivation of pollution-free vegetables, even organic vegetables Production is particularly important
