Abstract

The invention discloses a preparation method and an application of a selenium-enriched organic water-soluble fertilizer. The preparation method comprises the following steps: dissolving, acidifying, chelating, cooling, mixing, compounding and concentrating, wherein before the dissolving step, the transformation of organic selenium is carried out, which comprises the steps of adding water to sodium selenite to obtain a sodium selenite solution, soaking semen cassia in warm water, placing in a greenhouse until semen cassia becomes green, spraying the sodium selenite solution onto semen cassia buds once every day, after 10-25 days, picking buds and mashing to obtain organic selenium. The invention also discloses an application of the selenium-enriched organic water-soluble fertilizer. By the absorptive transformation effect during the germination process, inorganic selenium is transformed into organic selenium, the prepared selenium-enriched organic water-soluble fertilizer is high in content of selenium; by scientifically applying the selenium-enriched organic water-soluble fertilizer to crops, the drought resistance and cold resistance of the crops can be increased, the content of chlorophyllin in the crops is effectively increased, the phenomenon of decay is decreased, the contents of nutrients and yield of the crops are greatly improved and the content of selenium in agricultural products is effectively increased.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a production method and application of a selenium-rich organic water-soluble fertilizer. Background technique [0002] Organic water-soluble fertilizer is a compound fertilizer that is completely soluble in water. It can be quickly dissolved in water, quickly absorbed by crops, and not fixed by the soil. It is widely used. Most of the organic water-soluble fertilizers currently on the market only solve the effect of increasing production and income in the growth and development of crops, but cannot increase the content of selenium in agricultural products, and the produced agricultural products do not have health care effects on the human body. [0003] According to statistics, 42 countries and regions in the world are deficient in selenium. About 2 / 3 of the regions from the northeast to the southwest of my country are selenium deficient to varying degrees, an...
