How does corn apply to seedling fertilizer and joint fertilizer?

 

A: The seedling fertilizer should be applied early, lightly applied and biased, with nitrogen fertilizer as the main. In the base fertilizer, which is not matched with quick-acting fertilizer or unfertilized fertilizer, early application and light application can make up for the lack of available nutrients, and it has the effect of promoting roots and strong seedlings. Jointing fertilizer should be applied stably, mainly organic fertilizer, and a small amount of available nitrogen and phosphate fertilizers should be mixed in moderation. Lack of basal, Seedling and weaker maize, should increase the amount of fertilizer, typically 10-15 kg per acre topdressing 3-5 kg of ammonium bicarbonate or urea. The jointing fertilizer is usually applied before and after the jointing of the corn, when about 7-9 leaves are opened, and the ground fertilizer and seedlings should be properly chased and less chased. The thin and weak seed should be applied early.
