Embodiment 1

[0039] According to the content of each component specified in Table 1, add humic acid, L-proline, magnesium sulfate and copper sulfate in water, stir and dissolve to obtain a mixed solution; add selenium ore powder and grass Mushroom powder, stirring, standing at 24°C for 6h, adding 30% of the total mass of the mixed solution, stirring, standing at 24°C for 6h, adding the rest of the mixed solution, stirring to obtain selenium-enriched nutrient solution A.

[0040] Among them, the bran fermentation broth is obtained by fermenting the bran for 7 days by inoculating 88 cfu / g of Trichoderma pseudokonii and Pichia kundori with a mass ratio of 1:1, and then filtering.

[0041] Sodium selenite and lotus leaf extract were added to the culture medium of Anabaena anabaena, and after culturing at 26°C for 2 days, an organic selenium culture medium was obtained. Add water to the mixture, boil for 3 hours, filter to obtain the filtrate and filter residue; crush the filter residue to obta...

Embodiment 2

[0045] Repeat the method of Example 1 with the content of each component specified in Table 1 below, wherein, according to the mass ratio of 1:3, the selenium-enriched nutrient solution A and the selenium-enriched nutrient solution B were mixed, and stirred at a constant temperature of 25°C for 40 minutes to obtain a rich Selenium-enriched nutrient solution, but the selenium-enriched nutrient solution applied to lettuce has a different selenium-enriched cultivation method, that is, after the seedlings germinate for 5 days, dilute the selenium-enriched nutrient solution by 20 times, and the root irrigation amount is 90kg / m 3 Carry out the root irrigation treatment every 4 days, a total of 5 times of root irrigation; when the plant grows 4 true leaves, dilute the selenium-enriched nutrient solution 35 times, and the root irrigation amount is 60kg / m 3 Carry out the root irrigation treatment every 7 days, and at the same time of the root irrigation treatment, the spraying rate is 5...

Embodiment 3

[0047] Repeat the method of Example 1 with the content of each component specified in Table 1 below, wherein, according to the mass ratio of 2:2, the selenium-enriched nutrient solution A and the selenium-enriched nutrient solution B were mixed, and stirred at a constant temperature of 20°C for 30 minutes to obtain a rich The selenium nutrient solution is applied to the selenium-enriched cultivation method of lettuce, and the corresponding test results are listed in Table 1.

Abstract

The invention provides a selenium-rich nutrient solution as well as a preparation method and application thereof. The selenium-rich nutrient solution comprises a selenium-rich nutrient solution A and a selenium-rich nutrient solution B, and the mass ratio of the selenium-rich nutrient solution A to the selenium-rich nutrient solution B is (1-2):(2-3). The selenium-rich nutrient solution A comprises the following raw materials in parts by weight: 8-10 parts of humic acid, 6-8 parts of L-proline, 2-4 parts of magnesium sulfate, 2-4 parts of copper sulfate, 3-6 parts of selenium ore powder, 10-15 parts of straw mushroom powder, 20-30 parts of bran fermentation liquor and 25-35 parts of water; and the selenium-rich nutrient solution B comprises the following raw materials in parts by weight: 7 to 11 parts of cassava starch, 9 to 15 parts of bamboo powder, 4 to 6 parts of sodium selenite, 8 to 15 parts of liquorice root decoction dregs, 12 to 16 parts of radix astragali decoction dregs, 4 to 8 parts of fructus crataegi decoction dregs, 12 to 15 parts of lotus leaf extract and 12 to 18 parts of anabaena culture solution. The prepared selenium-rich nutrient solution is applied to crop cultivation, green and environment-friendly selenium-rich crops with high organic selenium content and less inorganic selenium residues can be harvested, the quality and nutritional value of the crops can be improved, the preparation method is simple, the product is easy to use, and the selenium-rich nutrient solution is quite suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of selenium-enriched products, in particular to a selenium-enriched nutrient solution and its preparation method and application. Background technique [0002] Selenium is an essential trace element in the life activities of the human body and plays an important role in the metabolism of the human body. When the selenium element in the body is lacking or insufficient, it is easy to reduce the immune function of the body or cause obstacles, and then cause various diseases. Nowadays, people usually take selenium-enriched foods, health products or nutritional supplements to promote the body's absorption of selenium and increase the content of selenium in the human body. Selenium is not only a trace element needed by humans and animals, but also an important element needed for plant growth and development. [0003] Selenium exists in the form of inorganic selenium and organic selenium in nature. Usually, inorg...
