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

[0022] The selenium-enriched peanut cultivation nutrient solution is obtained by the following preparation method:

[0023] 1) Preparation of raw materials: prepare 100 parts of purified water, 0.6 parts of L-selenomethionine, and 0.3 parts of hydroxyethyl cellulose;

[0024] 2) After mixing the raw materials in step 1), put them into a high-pressure tank and pressurize to 4kg / cm 2 , make the pressure uniform, and keep it for 2-3min, and then return to normal pressure within 1-3s to obtain a slurry, insert and cultivate mature liquid strains of Bacillus subtilis at 25°C at 5% by volume, and put it into a fermenter In the fermentation tank, sterile air was introduced into the fermenter to carry out stirring and fermentation, the stirring speed was 250r / min, the fermentation time was 3h, and the temperature was kept at 35-37°C. get.

Embodiment 2

[0026] The selenium-enriched peanut cultivation nutrient solution is obtained by the following preparation method:

[0027] 1) Raw material preparation: prepare 100 parts of purified water, 1.0 part of L-selenomethionine, and 0.1 part of hydroxyethyl cellulose;

[0028] 2) After mixing the raw materials in step 1), put them into a high-pressure tank and pressurize to 4kg / cm 2 , make the pressure uniform, and keep it for 2-3min, and then return to normal pressure within 1-3s to obtain a slurry, insert and cultivate mature Bacillus subtilis liquid strains at 25°C with a volume percentage of 10%, and put it into a fermenter In the fermentation tank, sterile air was introduced into the fermenter to carry out stirring and fermentation, the stirring speed was 250r / min, the fermentation time was 4h, and the temperature was kept at 35-37°C. get.

Embodiment 3

[0030] The selenium-enriched peanut cultivation nutrient solution is obtained by the following preparation method:

[0031] 1) Preparation of raw materials: prepare 100 parts of purified water, 0.8 parts of L-selenomethionine, and 0.2 parts of hydroxyethyl cellulose;

[0032] 2) After mixing the raw materials in step 1), put them into a high-pressure tank and pressurize to 4kg / cm 2, make the pressure uniform, and keep it for 2-3min, and then return to normal pressure within 1-3s to obtain a slurry, insert and cultivate mature Bacillus subtilis liquid strains at 25°C with a volume percentage of 8%, and put it into a fermenter In the fermentation tank, sterile air was introduced into the fermenter to carry out stirring and fermentation, the stirring speed was 250r / min, the fermentation time was 3h, and the temperature was kept at 35-37°C. get.

Abstract

The invention discloses a selenium-enriched peanut culture nutrient solution. A preparation method of the selenium-enriched peanut culture nutrient solution includes the steps of firstly, preparing raw materials, to be more specific, preparing 100 parts of purified water, 0.6-1.0 part of L-selenomethionine and 0.1-0.3 part of hydroxyethyl cellulose; secondly, mixing the raw materials in the first step, placing into a high-pressure tank, pressurizing to 4kg / cm<2>, allowing the pressure to be even, keeping the pressure for 2-3 minutes, restoring to normal pressure in 1-3 seconds to obtain slurry, inoculating a mature bacillus subtilis liquid strain into the slurry at 25 DEG C according to the volume ratio of 5-10%, placing into a fermentation tank, feeding sterile air into the fermentation tank, performing stirring fermentation, rapidly rising the temperature 70 DEG C after the fermentation, keeping the temperature for 0.5-1.0 hour, and deactivating to obtain the selenium-enriched peanut culture nutrient solution.

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...
