Embodiment 1

[0020] Fengdao No. 14 planting field, weighed 6 grams of potassium selenate, 8 grams of sodium selenite and 2 grams of diammonium hydrogen phosphate, mixed evenly, dissolved in 800 grams of water, after dissolving, in the initial stage of rice flowering and flowering, use Agricultural sprayer spraying rice paddy leaves. After spraying, if it rains, it should be re-sprayed once in time. Using the 2,3-diaminonaphthalene fluorescence detection method, the selenium content per kilogram of rice was detected to be 1.23-1.81 mg.

Embodiment 2

[0022] Yunguang No. 14 planting field, weigh 14.5 grams of potassium selenate and 0.5 grams of disodium hydrogen phosphate, mix them evenly, dissolve them in 1350 grams of water, and after dissolving, use an agricultural sprayer to spray rice leaves face. After spraying, if it rains, it should be re-sprayed once in time. Process the cultivated rice into selenium-enriched rice. Using the 2,3-diaminonaphthalene fluorescence detection method, the selenium content per kilogram of rice was detected to be 1.24-2.06 mg.

Embodiment 3

[0024] For Yueyou 122 planting field, weigh 12 grams of ammonium selenite and 3 grams of magnesium hydrogen phosphate, mix them evenly, dissolve them in 1020 grams of water, and after the dissolution, use an agricultural sprayer to spray rice leaves superior. After spraying, if it rains, it should be re-sprayed once in time. Using the 2,3-diaminonaphthalene fluorescence detection method, the selenium content per kilogram of rice was detected to be 1.00-1.74 mg.

Abstract

The present invention features that the selenium-rich rice is produced with selenium-rich rice grain, which is produced via spraying once selenium-rich agent during the earing up and flowering period of rice. The selenium-rich agent consists of selenium-containing inorganic compound and phosphate in the weight ratio of 10-20 to 0.5-3. The selenium-rich rice has high selenium content and the said planting process has no obvious influence on the yield of rice while raising the content of selenium.

Description

technical field [0001] The invention relates to a selenium-enriched product, in particular to a selenium-enriched rice and its production method and application. Background technique [0002] Selenium is an essential micronutrient element for humans and animals. It has many important physiological functions, the most important of which is that selenium participates in the formation of glutathione in the form of selenocysteine ​​(SeCys) in humans and animals. Oxidase (GSH-Px), thereby removing excessive active oxygen free radicals in the body. Exogenous selenium can induce the increase of GSH-Px activity and the activity of catalase. When the body is in a state of selenium deficiency, the activity of GSH-Px decreases, causing the accumulation of lipid free radicals and peroxides, which may induce abnormal lipid peroxidation (LPO), leading to cell membrane damage, tissue damage, and tumorigenesis. The study found that within a certain range of selenium concentration, the con...
