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

Embodiment 1

[0030]A cultivation method for selenium-enriched peanuts, comprising the steps of:

[0031] 1) Fertilization for soil preparation: Select suitable land and apply decomposed mixed fertilizer, then plow and ridge, the plow depth is 25-30cm;

[0032] 2) Seed selection and sowing: choose plump double-pod fruit peanut pods, dry the fruit for 2-3 days before sowing, and then peel off the shells. After peeling, select the complete large seeds as seed kernels, and then sow the seeds in good time after chemical seed dressing , sowing depth 3-7cm;

[0033] 3) Field management: pre-emergence weeding, phased fertilization, irrigation and drainage, and pest control are carried out after sowing, and timely harvesting;

[0034] It also includes spraying the cultivation nutrient solution on the leaves of the peanuts at the flowering and needle stage, the pod stage and the later stage of growth and development respectively, and the cultivation nutrient solution is obtained by the following pr...

Abstract

The invention discloses a method for cultivating selenium-rich peanuts. The method comprises the following steps of 1, soil preparation and fertilization; 2, seed selecting and sowing; 3, field management and further comprises the step that a cultivation nutrient solution is sprayed to leaves in the peanut blooming and seed growing period, the fruiting period and the later growth and development period. The cultivation nutrient solution is prepared through a method including the following steps that 1, raw materials are prepared, wherein 100 parts of purified water, 0.6-1.0 part of L-selenomethionine, 1.5-2.5 parts of water-soluble compound fertilizer with NPK being 15-15-15 and 0.1-0.3 part of hydroxyethyl cellulose are prepared; 2, after the raw materials in the step 1 are mixed, the mixture is placed in a steam cavity charge container, the pressure is 4 MPa, the mixture is heated to 150 DEG C, the temperature is kept for 2 min, then the pressure is fast released within 1 s to 3 s, slurry is obtained and inoculated with 5%-10% by volume of bacillus subtilis liquid strain cultured to be mature at the temperature of 25 DEG C, the mixture is placed in a fermentation tank, sterile air is introduced into the fermentation tank, stirring fermentation is carried out, after fermentation is completed, the temperature is fast raised to 70 DEG C to be kept for 0.5-1.0 h, inactivation is carried out, and the cultivation nutrient solution is obtained.

Description

technical field [0001] The invention relates to the technical field of peanut planting, in particular to a cultivation method for selenium-enriched peanuts. 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 crop in ...
