What are the fertilization methods for planting corn in summer? Please introduce that planting corn can refer to the following methods of fertilization: first, base fertilizer and seed fertilizer should be applied before sowing summer corn, mainly organic fertilizer, straw can also be directly returned to the field by using the previous stubble wheat, but appropriate amount of nitrogen fertilizer should be applied to adjust the ratio of carbon to nitrogen to accelerate the maturity of straw. The kinds of fertilizers are mainly available nitrogen, phosphorus and potassium fertilizers, such as diammonium phosphate (5-10 kg per 667 square meters), potassium sulfate compound fertilizer (45% content 10-15 kg per 667 square meters) and so on. Second, proper topdressing is very important. Topdressing plays an important role in the growth of maize. Available nitrogen is the main topdressing, and phosphorus and potash fertilizer is added according to different growth stages of maize. There are usually three times of topdressing, that is, seedling fertilizer, jointing fertilizer and panicle fertilizer. Summer maize needs more nitrogen, phosphorus and potassium at jointing and booting stage, so phosphorus and potassium fertilizer should be applied according to specific conditions. Third, skillfully using foliar fertilizer to spray 0.2% Mel 0.3% potassium dihydrogen phosphate 2-3 times at jointing stage can increase corn yield by more than 10%, and spraying 0.1% Mel 0.3% zinc sulfate aqueous solution at seedling stage and jointing stage can prevent the occurrence of corn white seedling mosaic disease. 4. careful application of special fertilizers at present, various names of special fertilizers in the agricultural materials market emerge in endlessly, among which there are many fake and shoddy products, so we should be careful when purchasing and using fertilizers, and select fertilizers according to the growth characteristics of corn and the nutrient content of the soil.
