Selenium-enriched rice and its production technology
In most areas of China, selenium is poor in soil. In recent years, various regions have researched and developed selenium-enriched agricultural products production technology. The development of selenium-enriched rice has important social and economic benefits for improving the people's health, improving the quality of rice, increasing the added value of rice, and increasing the income of farmers. In particular, the development of selenium-enriched nutrition under the current conditions of low grain yield Rice is an effective way to increase efficiency. Selenium in selenium-enriched rice has the physiological functions 1, strong anti-oxidation ability, similar to vitamin e, but has a greater effect and can regulate the rate of redox reaction in the body, and has natural detoxification and detoxification effects. 2. It has strong antagonistic effects on certain carcinogens. 3, can maintain the normal structure and function of the cardiovascular system, prevention of cardiovascular disease. 4, protect the visual organs. Second, selenium-enriched rice production technology in the rice break to the heading period with 1 bag of selenium-enriched production agent for foliar spray, can significantly improve the late mature phase, increase seed setting rate, increase grain weight, early maturation, increase production, And can double the selenium content. The selenium-enhancing agent can generally increase rice production by more than 5%. The maturity period is 2 days earlier. The selenium content in rice is increased by 2-7 times compared with the control. At present, there are many selenium-enriched products on the market. In general, selenium is added to solid foliar fertilizers containing large, medium, and micronutrients. Application method: Apply 1 bag of selenium-enriched agent per acre to the foliar spray from rice breakage to heading stage. Dissolve the parent agent in the bag with a small amount of water, then add the rest, and mix it with a sprayer. Evenly spray the surface. Spray time should be selected as soon as possible, such as spraying within 8 hours after the rain, to re-spray.
