Problems solved by technology

[0003] For a long time, there is no systematic and perfect high-yield cultivation method for peanut planting, so that the planting density of peanuts is not high, and the ventilation and light transmission conditions are poor, and the peanuts cannot perform photosynthesis well. The level of yield per mu is limited, usually 200-300 kg per mu

Abstract

The invention discloses a selenium-enriched peanut cultivation nutrient solution. A preparation method of the selenium-enriched peanut cultivation nutrient solution comprises the following steps: (1) preparation of raw materials: preparing 100 parts of purified water, 0.6-1.0 parts of L-selenomethionine and 0.1-0.3 part of hydroxyethyl cellulose; and (2) mixing the raw materials in the step (1), grinding into thick liquid to obtain pulp, sterilizing, cooling to the temperature of 25 DEG C, inoculating matured bacillus subtilis liquid strain in the pulp according to the volume percent of 5-10%, placing in a fermenting tank, feeding sterile air in the fermenting tank, carrying out stirring fermentation, after fermentation is finished, rapidly heating to the temperature of 70 DEG C, maintaining for 0.5-1.0 hour, and inactivating to obtain the final product.

Description

technical field [0001] The invention relates to the technical field of peanut planting, in particular to a selenium-enriched peanut cultivation nutrient solution. Background technique [0002] Peanut (peanut), formerly known as groundnut (scientific name: Arachis hypogaea Linn.), is a kind of nut with abundant output and wide consumption in my country. Peanut fruit contains protein, fat, sugar, vitamin A, vitamin B6, vitamin E, vitamin K, and mineral calcium, phosphorus, iron and other nutrients, contains 8 kinds of amino acids and unsaturated fatty acids needed by the human body, and contains lecithin , choline, carotene, crude fiber and other substances. The fat content is 44-45%, the protein content is 24-36%, and the sugar content is about 20%. Rich in vitamin B2, PP, A, D, E, calcium and iron. It also contains thiamine, riboflavin, niacin and other vitamins, which can promote the development of human brain cells and enhance memory. Peanut is an important economic cr...
