Method for planting agricultural green ecological selenium-rich rice

Abstract

The invention discloses a method for planting agricultural green ecological selenium-rich rice, which comprises the steps of I, selecting seeds; II, pretreating a land; III, carrying out pest control;IV, sowing seeds; V, providing field management; and VI, harvesting. The seed selecting step includes following criteria. The seeds are necessarily non-transgenic; the seeds are necessarily of low adsorption to heavy metals in soil; the seeds are necessarily of a first-grade rice variety having good quality and good taste; and a plurality of samples are selected at a base, and heavy metal, pesticide residue and pH value data of soil are detected. According to the method of for planting agricultural green ecological selenium-rich rice, on the basis of original ecological soil, the scientific and technical production method is adopted, qualified green selenium-rich rice is planted according to technical data and experimental results of multi-year detection zoning comparison by optimizing and removing and roguing, the selenium content is rich, products of different grades can be divided according to the data, dietary and medicinal traditional culture methods are fully utilized, and the maximum value is achieved.

Description

technical field [0001] The invention relates to the technical field of hybrid rice seed production, in particular to a method for planting agricultural green ecological selenium-enriched rice. Background technique [0002] Food is the most important thing for people, and rice is the first food, and selenium is the most important thing in rice. "Selenium" is one of the 15 trace elements necessary for the human body. The human body cannot produce it by itself, so it must be supplemented by selenium in food. Selenium in food Selenium in the soil can be absorbed and transformed by water and photosynthesis to make food contain selenium, so selenium-enriched food emerges as the times require, but 72% of China is deficient in selenium, and nearly 80% of people need selenium supplementation. Relying on 28% of the country's land to produce selenium-containing food is far from enough for people's daily needs. 80% of the people want to eat food that is environmentally friendly, green, ...

AI Technical Summary

Problems solved by technology

During the growth of crops, soil selenium or selenium fertilizer must be formed through the growth period of the crop itself and the transformation from inorganic to organic, but most selenium-enriched products are mixed, and the quality cannot be guaranteed, resulting in selenium-rich foods. The development of a virtuous circle
