Root dressing:
Peanuts can be sprayed with 2%-3% of superphosphate solution 2-3 times, 7-10 days once, and if the flower growth is weak, 100-200 grams of urea can be added to spray. Zinc deficiency, boron deficient soil, in the case of basal zinc and boron in the case of no application, can spray 0.1% -0.2% of zinc sulfate or borax aqueous solution in the seedling stage to initial flowering period, sprayed continuously 2-3 times.
