Green Food - Selenium-enriched garlic cultivation
Selenium is an essential element for humans and animals. It is an important element of life. Selenium deficiency in the human body can cause more than 40 diseases such as Keshan disease, Kashin-Beck disease, hypertension, coronary heart disease, and various types of cancer. Excessive intake of selenium by the human body can also cause toxic reactions such as fatigue, detachment of the skin, bone deformation, hemorrhage of the heart and renal cortex. This shows that selenium plays a very important role in human body function. The concentration of selenium in the human body lacks and poisons the concentration difference is very small, safe food inorganic selenium content is within the range of 0.1-1mg/kg, although medical use of selenium has been used chemical drugs, but the body's absorption and transformation effect is not ideal. Therefore, many scholars believe that natural food supplements selenium is a safer way. The Northeast Agricultural University Gardening Experiment Station uses garlic as Acheng Purple Peel, and the liquid selenium-containing fertilizer is Xinjian Selenium. New Selenium-rich Selenium is a high-efficiency organic leaf fertilizer composed of rare element selenium and natural humic acid, zinc, boron, molybdenum and bismuth. According to the requirements of green food production, soil, water and atmosphere should be monitored and implemented. Field trials were designed with a split-zone test, three replicates, four application methods, foliar spraying, root-irrigation, and foliar spray combined with irrigation and soaking. Each treatment used three concentration gradients of 250, 1000 and 4000 times. The soaking treatment was soaked for 24 hours with different concentration ratios before sowing. The leaves were sprayed with roots and the leaves were sprayed with roots. The treatments were carried out in the mother's retort stage and bolting stage. During the growth of garlic, the plant height and phenology period were regularly observed. Through the use of different concentrations, the results showed that the difference in selenium content in fresh garlic was extremely insignificant after treatment with 250-fold and 1000-fold garlic, and the difference in selenium content was very significant compared with the 4000-fold treatment. Therefore, selenium was supplemented. The best new selenium-enriched Kang concentration is 1000 times liquid and 250 times liquid, because the two concentrations are almost the same, in order to reduce the production cost should be used 1000 times liquid treatment. Since the newly-enriched selenium contains humic acid, it can promote the growth of garlic. The results showed that the garlic treated with the new selenium-enriched Kang can enter into the harvest period 1 to 2 days ahead of time, and the plant height is significantly higher than that of the control field. The garlic grown under the 250-fold solution has the best growing trend. The best garlic soaking treatment was significantly higher than other communities. It can be seen that the newly enriched humic acid in selenium can promote the growth of garlic. Selenium-enriched garlic can not only supplement the body's selenium elements, but also has certain economic benefits. According to the test results, the cost per mu for a dosage of 1,000 times is 66 yuan per mu, and the price for selenium-enriched garlic is 1 to 1.5 yuan per kg higher than that of ordinary garlic. An acre of land is 350 yuan more than regular garlic. ~ 525/yuan, which shows that the economic benefits of selenium-enriched garlic are very significant. Garlic is an indispensable condiment in people's daily life. Selenium-enriched garlic plays an important role in selenium supplementation for the human body and raises the nation’s health level. Therefore, the development of selenium-enriched garlic has broad market prospects and will increase economic, social and ecological benefits. It is very helpful. 1. The application of new selenium-enriched garlic to garlic showed that the selenium content of garlic soaked with 1000-fold solution was the highest in the safe edible range, and was the best method for selenium supplementation. 2. The new selenium-enriched Kang contains humic acid, which has a promoting effect on the growth of garlic, and its growth is significantly higher than that of the control. 3. The selenium-enriched garlic has an increase in mu production, and the selling price is also higher than that of ordinary garlic, so the economic benefit is very significant. 4. In the control, garlic was soaked with fresh water and its growth was higher than that of other controls. Therefore, it is recommended that soaking with water prior to garlic planting not only produces seedlings but also improves yield.
