Precautions:

Choose the right variety There are many corn varieties on the market now. Lodging resistance must be considered when selecting maize varieties. Varieties with better comprehensive characters such as stress resistance. Last year, due to the poor stress resistance of many varieties, the temperature of maize was high when it bloomed and scattered, and the temperature was low when it rained and filled, which led to bald tips and grain shrinkage.

Rational fertilization Many growers use the method of one-time application without topdressing (the base fertilizer is uncontrolled release fertilizer), commonly known as one-time fertilization. However, this is not only unscientific, but also late fertilization of corn will lead to smaller ears, early maturity and bald tips. The correct application method is to apply nitrogen fertilizer lightly at seedling stage and pay attention to using nitrogen, phosphorus and potassium compound fertilizer at big bell mouth stage.
