Soil improvement type selenium-rich special slow release fertilizer for soybeans, and preparation method thereof

Abstract

The invention discloses a soil improvement type selenium-rich special slow release fertilizer for soybeans. The soil improvement type selenium-rich special slow release fertilizer for soybeans comprises urea, cake-shaped rape seed dregs, soybean powder, corn starch, sucrose, saccharifying powder, yeast powder, a titanium compound, urea phosphate, potassium chloride, a magnesium potassium sulfate fertilizer, calcium humate, magnesium humate, boron humate, sodium humate, compound sodium nitrophenolate, a slow release agent and a selenium-rich additive. The invention also provides a preparation method of the soil improvement type selenium-rich special slow release fertilizer for soybeans. The special slow release fertilizer for soybeans contains abundant organic matters, inorganic matters and minerals, also contains abundant growth elements for promoting growth of soybeans, can effectively improve the nutrition structure of soybean growing soil, and improves the output and the quality of the soybeans; and coating of the slow release agent in the preparation process effectively improves the slow release performance of the fertilizer, makes nutrients be uniformly released and improves the growth efficiency of the soybeans, and the added selenium-rich additives can provide abundant selenium element for the growth of soybeans.

Description

technical field [0001] The invention relates to a slow-release fertilizer, in particular to a soil-improving type special slow-release fertilizer for selenium-enriched soybeans and a preparation method thereof. Background technique [0002] Selenium is an essential life element for the human body, and has been designated by the World Health Organization and the Chinese Medical Association as the third largest micronutrient health care element after iodine and zinc. Selenium is a component of human and animal glutathione peroxidase and a prosthetic group of the active site of the enzyme family. Selenium can participate in various metabolic processes of human tissues. Every important organ needs a certain amount of selenium to maintain normal functions. The human body has many functions such as anti-oxidation, preventing cancer, detoxification, enhancing human physical strength, and improving immunity. [0003] Soybeans in the prior art have single nutrients, low yield, and p...

AI Technical Summary

Problems solved by technology

[0003] The soybean nutrients in the prior art are single, the yield is low, and the quality is poor, which cannot meet people's needs. Therefore, it is urgent to design a special slow-release fertilizer for soil improvement type selenium-enriched soybeans to solve the problems in the prior art
