Method for producing green selenium-enriched high-calcium nutritious rice

Abstract

The invention discloses a method for producing green selenium-enriched high-calcium nutritious rice. According to the method, biological organic selenium-enriched high-calcium ecological fertilizer is uniformly spread over fields at a time when the field is ploughed and before the rice is transplanted, and the green nutritious rice obtained by processing the paddy produced by the method richly contains organic selenium of 0.16 to 0.22mg/kg and organic calcium of 230 to 350mg/kg respectively. The method is easy to implement, the production process of the prepared fertilizer is simple and easily implemented, the time and labor are saved, and the paddy rice applied by the fertilizer has strengthened photosynthesis, is resistant to drought, diseases and insects and is also high in yield and quality; and the rice produced by the method is green and pollution free, does not contain any hormone and chemically synthesized somatotropin, is free of pesticide pollution and replenishes selenium and calcium. The rice produced by the method is rich in nutrition, so people regularly taking the rice are healthier and have long life.

Description

technical field [0001] The invention relates to the technical field of agricultural product production, in particular to a production method of green selenium-enriched and high-calcium nutritious rice. Background technique [0002] Selenium was discovered in 1817, and was recognized by the World Health Organization in 1973 as "a trace element necessary for human and animal vitality". More than 40 countries and regions in the world are selenium-deficient or low-selenium. In my country, 72% of the regions and two-thirds of the population live in low-selenium or selenium-deficient regions. Selenium is closely related to the vitality of the human body. Selenium deficiency will lead to a high incidence of various diseases in the human body, such as cardiovascular and cerebrovascular diseases, hypertension, diabetes, Kashin-Beck disease, Parkinson's disease, cancer and more than 40 kinds of diseases. Therefore, the World Health Organization recommends that supplementing the human...

Problems solved by technology

[0003] Calcium is an important element of the human body. The content of calcium in the human body accounts for about 2% of the total body. Calcium deficiency can affect human health. A large amount of calcium needs to be taken in every day. Therefore, people choose to take inorganic calcium tablets to supplement, but biological Low potency and poor absorption

[0004] Since ancient times, people have mainly relied on planting rice to produce rice to supplement selenium and calcium, but the content of selenium and calcium in the soil is low, especially the selenium content is very low, which cannot meet the needs of human health. After searching domestic and foreign patents for selenium and calcium supplementation of rice , from the technological process, technical operation to implementation are cumbersome, and it is necessary to spray selenium and calcium supplements on the leaves of rice multiple times during the seedling raising stage, before transplanting, tillering stage, booting stage, flowering stage, early and middle stage of grouting, and to the seed stage. Fertilizers require a lot of manpower and material resources, but the effect is not very satisfactory
