1. Soak the seeds with 100% mg/kg sodium selenate solution for a few hours before sowing. Garlic production generally increases by 10%, and the selenium content increases.
2. Apply 13 grams of sodium selenate per mu in the soil before sowing garlic, combined with other basic fertilizers, and evenly apply it in the sowing ditch. Generally, the yield can be increased by about 15%, and it has a significant effect of increasing the selenium content.
3. Foliar spraying: One month before harvesting, sodium selenate is formulated to a concentration of 100 mg/kg, and the pure selenium applied per mu is 5 grams, and sprayed evenly on the garlic leaves, generally can increase garlic production by about 10%. And selenium is obviously enriched.
4. Precautions The amount of selenium used must be controlled accurately. Too much selenium will produce toxic effects, and too little will not have the effect of selenium enrichment. When applying soil and spraying, it must be uniform; spraying should be selected before 9 am on a sunny day , Use after 5 pm, spray after spraying in case of rain.
