A wonderful way to enrich selenium in garlic

Garlic has many beneficial physiological functions to the human body. Often eating 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 the income of farmers. This paper introduces the production method of selenium-rich garlic to the majority of farmers for your reference.

Generally speaking, with the increase of ph value and soil texture from coarse to fine, the content of available selenium in soil increases gradually. At present, the average content of soil available selenium in garlic producing areas is 9.5 μ g / kg, and the supply of selenium in more than half of the soil is relatively low. therefore, it is very necessary to take appropriate measures to supplement the level of soil selenium supply for the production of selenium-rich garlic.

The common application methods of selenium fertilizer in the production of selenium-rich garlic are foliar spraying, soil selenium application and seed soaking, which are introduced below.

Spraying: one month before harvest, 500g of special selenium fertilizer per mu was sprayed evenly on the leaves of garlic, which could increase the yield by about 10%. The total selenium content of garlic increased from 0.072 mg / kg to 15 mg / kg, and selenium was obviously enriched.

Soil fertilization: before sowing garlic, applying 1500 grams of special selenium fertilizer per mu, combined with other base fertilizers, evenly applied in the sowing ditch, the total selenium content of garlic can be increased to 12 mg / kg.

Seed soaking: soaking seeds with special selenium fertilizer solution for 12 hours before sowing, the yield of garlic is generally increased by 10%, and the total selenium content of garlic is increased to 3 mg / kg.

Note: the use of selenium should be controlled accurately, too little can not play the role of enriching selenium, too much will produce toxic effect; when spraying and soil application, it must be uniform; spray should be used before 9 am and after 5 pm on a sunny day, and should be sprayed after rain.
