Foliar spray fertilizer production of leafy vegetables is significant

Leafy vegetables (such as Chinese cabbage, celery, spinach, etc.) have higher yields, more nitrogen is needed in each growth stage, and the foliar fertilizer is mainly urea. The general spraying concentration is 2%, and the dosage per acre is 50 kg. The liquid is sprayed 2 to 4 times in the middle and late stages, and the 0.1% concentration of borax solution is sprayed once in the middle to prevent the "stem cracking" of celery, the "dwarf disease" of spinach, and the "bad leaf disease" of Chinese cabbage. Generally increase production by 15%-30%.
