Problems solved by technology

However, the development of selenium-enriched food is less at present, which is far from meeting people's needs.
[0003] Moreover, the existing selenium-enriched rice planting method has not been widely promoted, and there are obvious defects, such as the unstable quality of the selenium-enriched rice obtained by planting, wherein the content of selenium element is uneven, and cannot be stably controlled; at the same time, the planting method is complex and technically The requirements are high, and it is difficult to carry out extensive promotion and application; moreover, the high cost of planting causes the cost of selenium-enriched rice to increase, hindering the promotion of selenium-enriched rice

Abstract

The invention discloses a planting method of organic selenium-rich rice. The planting method specifically comprises the following steps: planting astragalus sinicus in selenium-rich soil, and collecting the astragalus sinicus after planting; preparing an organic fertilizer by using the astragalus sinicus; improving the soil of land after the land is planted with the astragalus sinicus; selecting avariety with high selenium absorption capacity for soaking seeds and raising seedlings, then transplanting and planting the seedlings on the land after the soil is improved, and applying the preparedorganic fertilizer; and applying a selenium-rich yield increasing agent in the growth process of the organic selenium-rich rice. The planting method disclosed by the invention is scientific and effective, and can successfully produce rice with uniform and stable selenium content; and moreover, the disclosed overall method is simple to operate, low in technical requirements, low in production costand beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of selenium-enriched rice cultivation technology, and more specifically relates to a planting method of organic selenium-enriched rice. Background technique [0002] Rice is one of the most important food sources of human diet. Selenium is an essential trace element for the human body and a natural antidote for some heavy metal elements. Scientific planting and management and obtaining selenium-enriched rice can solve the deficiency in the normal diet. The problem of selenium deficiency in selenium crowds, and the prevention of various diseases caused by selenium deficiency. However, the development of selenium-enriched food is less at present, which is far from satisfying people's needs. [0003] Moreover, the existing selenium-enriched rice planting method has not been widely promoted, and there are obvious defects, such as the unstable quality of the selenium-enriched rice obtained by planting, wherein t...
