Selenium-containing microelement foliage fertilizer for selenium-enriched cultivation of crops and use method of selenium-containing microelement foliage fertilizer

Abstract

The invention discloses a selenium-containing microelement foliage fertilizer for selenium-enriched cultivation of crops and a preparation method of the selenium-containing microelement foliage fertilizer. The foliage fertilizer is prepared from the following raw materials in parts by weight: 5-7 parts of sodium borate, 2-3 parts of ammonium humate, 5-7 parts of chelated iron, 4-6 parts of sodium selenite, 8-12 parts of fulvic acid potassium, 5-7 parts of a selenium yeast extract, 4-8 parts of dual-enzyme yeast, 1-2 parts of allicin, 3-4 parts of selenomethionine, and 3-7 parts of glutamic acid fermenting mother liquor of which the pH is 3-4. The foliage fertilizer disclosed by the invention is rich in selenium elements, and other raw material drugs are matched for use, so that the adsorption of crop leaf surfaces to nutrient elements such as selenium and the like can be promoted, the content of elements such as selenium and the like in crops is increased, further the content of the elements such as the selenium, the iron and the like in crop products is increased, the nutrient growth, the reproduction and the growth of crops can be promoted at the same time, the fruiting rate is increased, the stress tolerance of the crops is enhanced, the utilization rate of fertilizer constituents is high, and the quality of products is improved.

Description

technical field [0001] The invention relates to the field of foliar fertilizers, in particular to a selenium-containing trace element foliar fertilizer for selenium-enriched cultivation of crops and a use method thereof. Background technique [0002] The distribution of selenium in the natural environment is extremely uneven. The soil in two-thirds of my country is in a state of selenium deficiency, and the crops grown are at a low or deficient level of selenium. Whether the human body is deficient in selenium mainly depends on the level of selenium content in the food. Selenium supplementation can be obtained through clinical administration of selenium salts and selenium preparations. Selenium preparations have serious side effects, and the dosage is difficult to control and popularize. The cost of taking selenium-containing health care products such as Golden Partner and Selenium Capsules is high, and it is unaffordable for the general working class and the masses. Food s...

Problems solved by technology

[0004] Most of the existing selenium-enriched foliar fertilizer products are selenite or a mixture of selenite and nitrogen, phosphorus, and potassium fertilizers. After spraying, they cannot be wetted and attached to the leaves of crops, and cannot effectively absorb selenium-enriched nutrient solutions. , so the waste is relatively high, and the crops at the production site cannot meet the requirements once sprayed; and the content of other elements in the existing selenium-enriched foliar fertilizer is small, which cannot promote the growth of plants very well
