Selenium-rich soil fertilizer for planting selenium-rich vegetables

Abstract

The invention discloses a selenium-rich soil fertilizer for planting selenium-rich vegetables. The selenium-rich soil fertilizer is prepared from, by weight, 15-20 parts of animal fecal biochar, 15-25parts of selenium-rich malt shell powder, 5-10 of alfalfa powder, 6-10 parts of Cardamine Hupingshanesis powder, 5-10 parts of waste bacterium stick powder, 2-4 parts of amino oligosaccharins, 5-10 parts of selenium-rich malt meal and 3-6 parts of enzyme bacteria. The selenium-rich soil fertilizer obtained in the invention is rich in organic selenium which can be absorbed and utilized by vegetables and other plants, and also can improve the aggregate structure of soil, activate nutrient elements and improve the chemical fertilizer utilization rate; and the selenium-rich soil fertilizer also can balance minerals and nutrients in the soil, adjust the pH value of the soil, enhance the activity of various enzymes in the soil, effectively promote the absorption of nutrients by roots of vegetables and other plants, increase the number of soil microorganisms, promote the activities of the microorganisms, maintain the diversity of the soil organisms, promote the circulation of soil nutrientsand the flow of energy and promote the growth of vegetables and other plants.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a selenium-rich soil fertilizer for planting selenium-rich vegetables. Background technique [0002] Selenium is an essential trace element for the human body and participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins, and has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers. The metabolite methyl enol has strong anticancer activity. At the same time, selenium has the effect of reducing and alleviating the toxicity of heavy metals. [0003] At present, with the continuous improvement of people's living standards, people's pursuit of health is more urgent, and the demand for selenium-rich foods is also increasing. Biological...

Problems solved by technology

[0004] At present, most selenium fertilizers are obtained by adding chemical selenium salts or tin ores to common fertilizers. Although these selenium salts or selenium-enriched ores are easy to obtain, they have certain toxicity. Improper use will pollute the soil, and selenium ores and The selenium in selenium salt is not easy to be absorbed by plants. To obtain vegetables with high selenium content, the amount of fertilizer must be increased, which not only increases the cost, but also causes problems such as excessive fertilization and hardening of the soil.
