Problems solved by technology

Selenium is divided into plant active selenium and inorganic selenium. Inorganic selenium generally refers to sodium selenite and sodium selenate, including yeast selenium and malt selenium with a large amount of inorganic selenium residues. They are obtained from by-products of metal mineral deposits. Inorganic selenium has Highly toxic and not easily absorbed, not suitable for human and animal use

Abstract

The invention provides a selenium-rich fertilizer capsule and a preparation method thereof. The preparation method of the selenium-rich fertilizer capsule comprises the following steps that 1, 30-60 parts of gelatin is dissolved into water at 35-45 DEG C, 1-2 parts of sodium selenite is added and heated to 45-60 DEG C, and a solution A is formed; 2, 15-30 parts of organic fertilizer or inorganic fertilizer is added into the solution A and stirred and dispersed for 40-70 minutes; 3, 5-10 parts of an emulsifier is added into the solution A and stirred for 40-70 minutes to obtain an emulsion, then the emulsion is cooled to room temperature and the reaction continues for 1-2 hours; 4, the emulsion obtained in step 3 is subjected to vacuum drying to obtain the selenium-rich fertilizer capsule.The selenium-rich fertilizer capsule can improve the selenium content in soil, so that the yield and quality of crops are improved, and selenium-enriched crops are cultivated. Meanwhile, the fertilizer can be controlled to be released by capsule fertilizer, so that the utilization rate of the fertilizer is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a selenium-rich fertilizer capsule and a preparation method thereof. Background technique [0002] In my country's agricultural production, the utilization rate of traditional chemical fertilizers is only about 30%. Excessive use of chemical fertilizers will cause soil compaction, water eutrophication, and environmental pollution. How to improve the utilization rate of chemical fertilizers, make crops "eaten", achieve high absorption and low pollution, this has become the direction of new fertilizer development. [0003] Selenium-enriched agricultural products, that is, agricultural products rich in selenium, can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium is a chemical element, the chemical symbol is Se, a non-metal, which is an essential nutrient element for animals and a beneficial nutrien...
