Selenium is one of the essential trace elements in the human body. Enjoy the "longevity element", "King of Cancer" and other reputations. Chinese famous nutritionist Yu Ruomu pointed out: "The lack of selenium in the human body is a major issue that affects the health of hundreds of millions of people. We should do a good job of supplementing selenium like iodine supplements."
For several consecutive years, the Jianping County Agricultural Technology Promotion Center planted selenium-enriched millet at the Blackwater Test Demonstration Base. After detection by the provincial authorities, selenium content was several times or even several times higher than that of ordinary millet. After several years of promotion, it has been possible to plant large areas in Jianping.
In 2017, the Agricultural Center conducted a selenium-enhanced fertilizer effect test on other crops. The potato as the fourth staple food crop was also among them. The test area was 50 mu. The introduction of "Kangxibao" selenium-enriched organic water-soluble fertilizer produced by Guangxi Pensiubao Co., Ltd. was used to spray the plant. The main technical point was to continuously spray 3 times during the growing period of potato tuber, namely budding period, early flowering period and flowering period. Each time, 60 ml per mu and 45-60 kg of water are exchanged, and the interval between sprays is 7-10 days, and the use is stopped 10 days before harvest.
