Selenium-rich planting soil, preparation method thereof and application of soil

Abstract

The invention provides selenium-rich planting soil. Soil of a traditional land is improved into a culture medium suitable for culturing, and the culture medium is prepared from, by weight, 50-60 partsof common cultivated land soil and 3-10 parts of organic selenium-rich fertilizers. The organic selenium-rich fertilizers include selenium-rich fertilizers and organic fertilizers. According to the selenium-rich planting soil, the selenium-rich fertilizers prepared from protein materials, selenium ore powder and graphene oxide and the traditional plant straw organic fertilizers are combined, theselenium-rich planting soil serves as novel planting soil and can effectively enhance selenium-rich content in the soil and increase fertility of the soil, absorption of crops is facilitated, the absorption rate of the crops for selenium elements is greatly increased, growth of plants at stages is facilitated, and nutrition of the crops is enhanced.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, and more specifically, relates to a selenium-rich soil for planting and a preparation method and application thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. my country is a country with a large area of ​​selenium deficiency, and about 100 million people in 15 provinces and municipalities are in the selenium deficiency zone. Selenium-deficient adults supplemented with more than 50 micrograms of selenium per day can improve the body's immunity, especially in cancer prevention and suppression. Selenium is a rare element in nature. We mainly supplement the selenium we need through food and drinking water, which require high selenium content in food and drinking water. Therefore, selenium-rich food has become our health food. The use of selenium-rich fertilizers for crops will also increase the selenium content of their products. ...

AI Technical Summary

Problems solved by technology

[0004] Among the existing selenium-enriched products, selenium-enriched fertilizers are generally used to make the crops contain selenium, and the unit application rate is large, and the absorption rate of the crops is not high, resulting in great waste; after retrieval, the soil is enriched It is rare to add graphene raw materials to selenium improvement. The combination of traditional soil fertility and selenium-rich improvement is a blank in the field of agriculture.
