Problems solved by technology

The soil conditioner is applied to the cultivation of clay-based cereal crops, which can effectively improve the selenium conversion rate of cereal plants, but cannot adjust the soil pH value, and cannot be used to improve saline-alkali land
[0005] The existing selenium-containing soil conditioners on the market are prepared by directly adding chemical selenium compounds to the conditioner instead of using natural selenium ore. It is easy to cause soil burden and soil compaction due to incomplete absorption
However, the selenium-containing soil conditioner prepared directly from selenium ore in the traditional process is difficult to absorb selenium and cannot be fully utilized

Abstract

The invention provides an environmental-friendly selenium-rich soil conditioner and a preparation method thereof. The soil conditioner is prepared from zeolite powder, desulfurized gypsum, grass ash,animal skin and bone, sawdust, selenium ore powder, humic acid, compound trace elements, sodium alginate, brown algae powder, a jerusalem artichoke extract, black fungus polysaccharide, and compositemicrobial bacterial liquid, wherein the zeolite powder is clinoptilolite having silica content of 58% to 60%, density of 3.4 to 3.7g / m<3> and fineness of 200 to 280 meshes. The selenium-containing soil conditioner with high absorption rate, which is prepared from natural selenium ores, has the functions of adjusting the pH value of soil, alleviating soil hardening, increasing the content of organic matter in soil and improving the function of aggregate structure.

Description

technical field [0001] The invention relates to the technical field of soil conditioning, in particular to a selenium-enriched and environment-friendly soil conditioner and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for humans and animals, and an important component to maintain enzyme activity, and participates in important physiological processes of immunity and anti-cancer. Studies have found that various diseases of the human body are related to selenium deficiency, such as anemia, cancer, hepatitis and so on. Adequate intake of selenium is very necessary to maintain human health. Although selenium is not an essential element for plant growth, it can affect the growth and development of plants, participate in photosynthesis and respiration of plants, and improve plant resistance to stress. [0003] Chinese patent CN103497041A discloses a selenium-rich fertilizer, including sodium selenite, urea, chlorinated paraffin...
