Selenium-rich rice planting technology

Abstract

The invention discloses a selenium-rich rice planting technology. The selenium-rich rice planting technology comprises the following steps of land preparation, seed treatment, sowing, rice seedling raising, rice transplanting, fertilization, field management and harvesting, wherein the implementation mode of the land preparation is to select a land with sufficient water resources and fertile soiland away from serious pollution as a planting rice field; the implementation mode of the seed treatment is that seeds are soaked in a selenium-rich nutrient solution, then taken out and washed up, subjected to ultraviolet sterilization and soaked with clear water for pregermination. The selenium-rich rice planting technology has the advantages that the design is reasonable, the double selenium supplement effects of selenium-rich rice are achieved by soaking the seeds in the selenium-rich solution and applying selenium-rich fertilizers on growing rice seedlings, the selenium content in the riceis greatly improved, the difficulty that selenium elements are difficult to absorb completely in a selenium-rich rice technology in the prior art is overcome, and the selenium-rich rice planting technology is worth popularizing and using in the field of rice planting.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a technique for planting selenium-enriched rice. Background technique [0002] With the continuous improvement of people's living standards, people are paying more and more attention to their own health. Compared with some health foods, people are usually more willing to pursue some healthy and green foods, and use diet therapy instead of medicine supplements. [0003] Rice is the staple food of our country, and its selenium content is closely related to the nutritional status of human selenium. Rice is easy to store, can be sold for a long time, and consumers can also eat organic selenium rice for a long time, so that the selenium supplement can last longer and the effect will be more obvious. Therefore, organic selenium rice is the best way for ordinary people to supplement selenium. However, most of the existing selenium-enriched rice is sprayed with selenium-containing inorgani...

Problems solved by technology

However, most of the existing selenium-enriched rice is sprayed with selenium-containing inorganic salt on the rice leaf surface at the early stage of rice flowering and flowering. This method of page spraying makes it difficult for all selenium to be absorbed, and the selenium-enriched effect cannot be achieved.
