Integrated method for producing organic selenium enriched rice

Abstract

The invention provides an integrated method for producing organic selenium enriched rice. The integrated method is characterized by specifically comprising the following steps: selecting seeds; preparing a rice field; accurately sowing seeds; managing a land for growing field crops; and harvesting, transporting, storing and treating by-products. The production of the organic selenium enriched rice is finished through the steps. The integrated method has the beneficial effects that the content of selenium in the rice can be quantitatively controlled and the requirements of different consumer groups are met. The content of the selenium in the rice can determined to a certain specific value of 0.04-0.3mg/kg in national standards through adjusting the unit use amount of a selenium enriched slow release fertilizer according to the content of the selenium in soil, so that the selenium enriched rice with different selenium contents is developed, the requirements on different selenium supplementing amounts of special consumer groups, such as women, children, old people or patients are met, and the quantification and functionalization of selenium supplementation are realized.

Description

Technical field: [0001] The invention relates to an integrated method for producing organic selenium-rich rice, which belongs to the field of agricultural high-tech. Background technique: [0002] Selenium (Se) is one of the essential trace elements for the human body. According to statistics, there are more than 40 countries and regions in the world that are deficient in selenium, and 2 / 3 of my country's land is internationally recognized as deficient in selenium, involving 22 provinces (cities, districts), of which Jiangsu, Zhejiang, Anhui and other regions are seriously deficient. In the selenium area, about 700 million people in the country have a long-term serious shortage of selenium intake. The per capita selenium intake in my country is only 36 micrograms per day, which is significantly lower than the minimum recommended values ​​of 50 micrograms and 60 micrograms per day by the Chinese Nutrition Society and the World Health Organization, and less than 1 / 3 of Japan a...

AI Technical Summary

Problems solved by technology

Since the production and processing of most selenium-enriched agricultural products has not formed an industrial cluster or the complete set of technologies is immature or local standards have not been formulated, the selenium content of the products exceeds or fails to meet the standard or the inorganic selenium content is low to varying degrees.
