Causes of Corn Lodging and Preventive Measures

The falling or rooting of corn stem has a great influence on the high yield and stable yield of corn. There are five factors that contribute to corn lodging:

1. Caused by natural conditions. Maize is a high stalk crop, and it is easy to fall down if it encounters strong winds and heavy rain during growth and development.

2. Improper selection of species. Some varieties are finer, softer, and have higher plant height and ear position. Plants are susceptible to lodging when exposed to harsh environments.

3. The planting density is too large. Field plants are turbulent, with poor ventilation and light transmission, and long stems. In addition, some corn plots do not seedling after sowing, resulting in a large field population and poor lodging resistance.

4. Improper fertilization. Some plots adopt the "big shelling" top dressing method at the seedling stage, so that the amount of nitrogen fertilizer in the seedling stage is too large, and phosphorus, potassium fertilizer and trace elements are less, resulting in unnecessary stalk growth, resulting in excessive basal internodes and plants. Too high, easy to fall
