I. Causes of corn delivery
1, related to corn varieties. At present, the production of Xianyu 335, Huanong 138, etc., in the corn production has been seriously diverted. This is determined by the characteristics of the species.
2, related to corn weather conditions. This year, corn seedlings have been exposed to high temperature and drought for a long time under meteorological conditions. The growth of main stems of maize has been inhibited, and the latent buds at the leafhoppers have begun to differentiate and pump. With the arrival of watering or the rainy season, they have accelerated growth.
3. It is related to the nutritional status of corn seedlings. Due to the promotion of integration of seed fertilizers, maize has sufficient nutrients at seedling stage, and the main stem of maize is restrained from growing due to the weather, so it stimulates the growth and development of latent shoots.
Second, the solution
1, timely removal of childbirth. Because the childbirth will consume a large amount of nutrients, moisture, resulting in poor air ventilation in the field.
2, next year can be changed without crops or tiller light varieties for planting.
