High-yield and selenium-rich barley cultivation method

Abstract

The invention discloses a high-yield and selenium-rich barley cultivation method. Insecticidal and disinfection soil applied to each mu of land before seeds are sown is prepared from 250 ml of 40% phoxim emulsifiable concentrate or 40% isofenphos-methyl emulsifiable concentrate, 1-2 kg of mixing water and 25 kg of mixing fine sand soil. The high-yield and selenium-rich barley cultivation method includes uniformly broadcasting the insecticidal and disinfection soil to land surfaces before the lands are plowed, and plowing the insecticidal and disinfection soil under soil along with land plowing; mixing seed coating agents with the seeds; sowing the seeds in due time according to soil moisture statuses; spraying selenium-rich foliar fertilizers on leaf surfaces in calm and fogless early mornings or evenings at heading stages; spraying selenium-rich foliar fertilizers on the leaf surfaces in calm and fogless early mornings or evenings at initial filling stages; spraying selenium-rich foliar fertilizers on the leaf surfaces in calm and fogless early mornings or evenings at middle filling stages. Every 1.3 kg of selenium-rich foliar fertilizers sprayed on the leaf surfaces in the calm and fogless early mornings or evenings at the heading stages are mixed with 45-50 kg of water to be sprayed on the leaf surfaces in each mu of land. Every 1.3 kg of selenium-rich foliar fertilizers sprayed on the leaf surfaces in the calm and fogless early mornings or evenings at the initial filling stages are mixed with 35-40 kg of water to be sprayed on the leaf surfaces in each mu of land. Every1.3 kg of selenium-rich foliar fertilizers sprayed on the leaf surfaces in the calm and fogless early mornings or evenings at the middle filling stages are mixed with 35-40 kg of water to be sprayedon the leaf surfaces in each mu of land. Selenium-rich fertilizers comprise 80%-85% of urea, 8%-8.5% of potassium dihydrogen phosphate, 8%-8.5% of chitin and 0.045%-0.005% of organic selenium with theselenium content of 6 g / l. The high-yield and selenium-rich barley cultivation method has the advantages that the purpose of increasing the selenium content of barley and the yield of the barley canbe achieved, and diseases of the barley can be effectively controlled.

Description

technical field [0001] The invention relates to a high-yield selenium-rich cultivation method for barley. Background technique [0002] Selenium is an essential trace element for the human body and has a significant impact on the health of humans and animals. Studies have confirmed that selenium has important functions such as anti-oxidation, cancer prevention, immune function regulation, and participation in the synthesis of various proteins in the human body. However, the human body cannot synthesize selenium itself, and the selenium element in the human body is mainly absorbed through food. Therefore, the amount of selenium in food directly affects the level of selenium nutrition in the human body. In general, my country is a selenium-deficient country, and 72% of the soil is low-selenium or selenium-deficient soil, which means that the selenium content of crops planted on this soil is also very low, which cannot meet the needs of the human body. Studies have shown that...

In general, my country is a selenium-deficient country, and 72% of the soil is low-selenium or selenium-deficient soil, which means that the selenium content of crops planted on this soil is also very low, which cannot meet the needs of the human body. Studies have shown that in Two-thirds of my country's selenium intake is insufficient, seriously affecting the health of local residents
