Cultivation of selenium-rich garlic
Selenium is an essential nutrient element for human beings and animals, and it is an important life element. Selenium deficiency in human body will lead to more than 40 kinds of diseases, such as Keshan disease, Kaschin-Beck disease, hypertension, coronary heart disease and various cancers.
The gardening experiment station of Northeast Agricultural University used garlic as Acheng purple garlic and liquid selenium fertilizer as new selenium-rich Kang. Xinfu selenium Kang is a kind of efficient organic foliar fertilizer composed of rare element selenium and natural humic acid, zinc, boron, aluminum, germanium and so on.
Foliar spraying, root irrigation and foliar spraying combined with root irrigation were used to soak seeds and the concentration of seed theory was 250x, 1000 and 4000 times. The seed soaking treatment was soaked with different concentration ratio of medicine solution for 24 hours before sowing, foliar spray irrigation root, foliar spraying combined with root irrigation treatment in garlic mother stage and bolting stage, respectively.
The application of Xinfu selenium Kang to garlic showed that the selenium content of garlic treated with 100 times solution was the highest in the safe edible range, which was the best way to supplement selenium.
While the yield of selenium-enriched garlic increases per mu, the selling price is also higher than that of ordinary garlic. when the concentration is 1000 times, the consumption per mu is 66ml, and the cost is 8.00yuan. The price of selenium-enriched garlic is 10ly15 yuan / kg higher than that of ordinary garlic, and the yield of one mu of selenium-enriched garlic is 350ly525 yuan higher than that of ordinary garlic.

Production technology of selenium-rich garlic
Garlic is a favorite food for people, it has many beneficial physiological effects on the human body, often eat garlic, can improve human immunity and prevent a variety of diseases. These physiological effects of garlic are related to the fact that it contains more selenium. Therefore, how to further improve the selenium content of garlic is of great significance not only to improve the therapeutic value of garlic, but also to increase the added value of garlic, increase the export of garlic and increase farmers' income. This paper introduces the production method of selenium-rich garlic to the majority of farmers for your reference.

Prevent the regeneration of degenerated leaves of garlic cloves
In a certain period of garlic growth, the scale buds begin to differentiate, the leaves degenerate, the scale buds gradually form cloves, and the scales outside the degraded buds form the outer skin of cloves, which is the general law of normal growth of garlic. At the same time when the garlic stalk is exposed, a circle of small garlic leaves grows around the garlic stalk, and 5Mel 7 leaflets grow around the garlic stalk. These leaflets are a long new leaf growing from the outer skin of the new garlic cloves along the garlic stalk, but the growth point of the new garlic cloves does not sprout. This is called the regrowth phenomenon of degenerated leaves of garlic, and some are called two.
