How to cultivate selenium-rich garlic

The commonly used selenium application methods for producing selenium-rich garlic are seed soaking, soil selenium application and foliar spraying. The cultivation techniques for producing selenium-rich garlic are introduced below.

1. Soak the seeds with 100% mg / kg sodium selenate solution for a few hours before sowing. Garlic production is generally increased by 10%, and selenium content is increased.

2. Before sowing garlic with selenium in soil, applying 13 grams of sodium selenate per mu, combined with other base fertilizers, evenly applied in the sowing ditch can generally increase the yield by about 15%, and has a significant effect on increasing selenium content.

3. Foliar spraying one month before harvest, sodium selenate was mixed into a concentration of 100 mg / kg, and 5 grams of pure selenium was applied per mu, which was evenly sprayed on the leaves of garlic, which could increase garlic yield by about 10%, and selenium was obviously enriched.

4. precautions: the use of selenium should be controlled accurately, too much will have a toxic effect, and too little will not play the role of enriching selenium. Soil application and spraying must be uniform; spraying should be used before 9 am and after 5 pm on a sunny day, and should be sprayed after rain.
