Embodiment 1

[0028] Before wheat sowing, the nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., product model XJCP002) was applied to the field as a base fertilizer at an amount of 15 kg per mu, and then the seeds were sown after rotary tillage, and appropriate irrigation was carried out. Maintain proper moisture content in the soil, and carry out normal field water and fertilizer management, so that the high-selenium wheat can fully absorb and transform the selenium element in the nano-selenium plant nutrient and convert it into organic selenium. After the wheat is harvested, use a mixer and select The high-selenium wheat was mixed and selected by machine. The selenium content in the high-selenium wheat was detected to be 5.16mg / kg, the RSD value was 8.3%, and the proportion of organic selenium exceeded 70%.

Embodiment 2

[0030] Before wheat sowing, the nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., product model XJCP002) was applied to the field as a base fertilizer at an amount of 30 kg per mu, and then sowed after rotary tillage, and appropriate irrigation treatment was carried out. Maintain proper moisture content in the soil, and carry out normal field water and fertilizer management, so that the high-selenium wheat can fully absorb and transform the selenium element in the nano-selenium plant nutrient and convert it into organic selenium. After the wheat is harvested, use a mixer and select The high-selenium wheat was mixed and selected by machine. The selenium content in the high-selenium wheat was detected to be 12.1mg / kg, the RSD value was 16.2%, and the proportion of organic selenium exceeded 70%.

Embodiment 3

[0032] During the overwintering period of wheat, the nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., product model XJCP002) is evenly applied to the field at an amount of 30 kg per mu, and then properly irrigated to maintain proper soil moisture. And carry out normal field water and fertilizer management, so that the high-selenium wheat can fully absorb and transform the selenium element in the nano-selenium plant nutrient and convert it into organic selenium. After mixing and selecting, the selenium content in the high-selenium wheat was detected to be 30.6mg / kg, the RSD value was 18.6%, and the proportion of organic selenium exceeded 70%.

Abstract

The invention discloses high-selenium wheat. According to the high-selenium wheat, 5-150mg / kg of selenium and organic selenium being more than or equal to 70% are contained in the grains of wheat. The invention also discloses a production method of the high-selenium wheat, which is as follows: the high-selenium wheat is obtained by applying 15-30kg of nano selenium plant nutrient agents in each mu of soil during the sowing period, the wintering period, the period of seedling establishment, the elongation period and the pustulation period. The nano selenium plant nutrient agents are produced by Suzou SeTek Technology Co. Ltd. According to the high-selenium wheat, the selenium content is extremely high, the selenium mainly exists in an organic selenium form so as to be beneficial to the absorption of people or animals, the standardization of the selenium content is high, the demands of industrial production can be met, and the selenium content in a preliminarily processed product is stable.

Description

technical field [0001] The invention relates to a high-selenium wheat and a production method thereof, belonging to the technical field of functional food research and development. Background technique [0002] Wheat (wheat) is a kind of gramineous plant widely planted all over the world. Wheat is the food crop with the second total output in the world, second only to corn. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A, etc. It is one of the common foods for humans and animals. [0003] The selenium content of common wheat is generally between 10-30ug / kg according to regional differences. Most of the selenium-enriched wheat appearing on the market is obtained by page spraying technology or the technology of directly soaking seeds with selenium-enriched solution (such as China CN 101897266A), most of its selenium content is between 100-400ug / kg, and this method is very easy to cause poisonous effect on wheat, and t...
