Description
Technical Field
The invention relates to selenium-rich soil, in particular to a selenium-rich soil additive and a preparation method and application thereof.
Background
Selenium is a nutrient element necessary for animals and also a nutrient element beneficial to plants. Selenium is divided into plant active selenium and inorganic selenium, wherein the inorganic selenium generally refers to sodium selenite and sodium selenate, is usually obtained from byproducts of metal mineral reserves, has high toxicity, is not easy to be absorbed, and is not suitable for human and animals; the plant active selenium is formed by combining biotransformation with amino acid, generally existing in the form of selenomethionine, and is a selenium source which is allowed to be used by human beings and animals.
A large number of researches show that selenium has the effects of resisting cancer, resisting oxidation and the like, can enhance the immunity of a human body, regulate the absorption and utilization of various vitamins and regulate the synthesis of protein, and is also an important component of the function of muscle. Selenium deficiency in humans can cause dysfunction of some vital organs, which in turn leads to decreased immune competence and the development of many serious diseases. At present, people with low selenium or selenium deficiency can prevent diseases such as tumor, liver disease and the like by supplementing selenium in a proper amount from diet, improve the immunity of the organism and maintain the normal functions of important organs such as heart, liver, lung, stomach and the like.
However, a plurality of countries in the world are in selenium-deficient areas, a plurality of provinces in China are also in selenium-deficient or low-selenium zones, and the selenium content in food and soil in one area has a direct relation with the incidence rate of cancers, so that the significance of researching selenium-enriched soil and further developing natural selenium-enriched agricultural products is great.
The Chinese patent application with publication number CN 107980541A discloses a selenium-rich soil for planting, which improves the soil of the traditional land into a cultivation medium suitable for cultivation, wherein the cultivation medium is prepared by mixing the following raw materials in parts by weight: 50-60 parts of common cultivated land soil and 3-10 parts of organic selenium-rich fertilizer; wherein, the organic selenium-rich fertilizer consists of two parts: comprises a selenium-rich fertilizer and an organic fertilizer, wherein the dosage of the selenium-rich fertilizer and the organic fertilizer is 1:5-10 by weight; the selenium-rich fertilizer is prepared from the following raw materials in parts by weight: 95-100 parts of protein raw material, 1-5 parts of selenium mineral powder and 0.5-1 part of graphene oxide; the organic fertilizer is prepared by retting 35-40 parts of crop straw padding and 60-65 parts of livestock and poultry manure by weight, and the straw is prepared from 30-50 parts of soybean straw, 10-20 parts of corn straw and 10-20 parts of wheat straw by weight. When the selenium-rich soil is used for planting the sweet potatoes, the selenium content is only 24.9 mug/kg, and the selenium content is lower.
In view of this, the invention is particularly proposed.
