The first time before and after jointing (9 ~ 10 leaves), commonly known as attacking stalk fertilizer, the main purpose is to ensure the robust growth of corn plants, generally 10 kg of urea per mu, can also be applied high quality organic fertilizer 1000 ~ 1500 kg. The second time in the first 10 to 15 days before the heading of corn, commonly known as the earing fertilizer, this fertilization has a great effect on the number of ears and the number of grains per ear, and can apply 20 to 25 kg of urea per acre. The third time in the corn to male to flowering period, commonly known as attacking fertilizer, generally 10 kg per mu, this fertilization has an important role in preventing premature senescence and increasing grain weight. It should be pointed out that if the previous topdressing is more, corn growth Strong corn fields without de-fertilization can be used without fertilization. In order to prevent post-fertilization and ensure the robust growth of the plants, foliar fertilization can also be carried out in combination with pest control. 100 g of potassium dihydrogen phosphate per acre, 50 kg of water can be added, and the corn field can be sprayed. Zhuangsuiling is a cationic meridian active conditioning agent that does not contain pesticides, fertilizers or cytokinin components. It activates the plant's ecological growth positive energy, broadens the plant's conduit path, and enhances the plant's water absorption and absorption. Before each fertilization of corn, 50--80 kg of water plus Zhuangsuiling Capsules sprayed on corn leaf surface can increase the quality of corn pollination, fertilization and grouting, increase 1000-grain weight, and increase yield and quality.
