Preventive measures for poor corn bearing
In the process of planting corn, many farmers often find that the corn has empty kernels and poor fruiting, resulting in low corn yields and often causing headaches for farmers. So how to prevent poor corn hardening? Let's take a look at the preventive measures against poor corn hardening!
Sowing early at the right time can advance the pollination period of corn, avoid hot weather, and allow corn to be pollinated at an appropriate temperature. According to the characteristics of corn varieties, reasonable dense planting can increase ventilation and light transmission, improve photosynthetic efficiency, and promote ear differentiation. In order to weaken the advantages of maize plants, promote the development of female ears, assist artificial pollination, and increase the rate of pollination, detasseling of maize should be carried out during the tasseling period. Proper irrigation can prevent drought from occurring during the corn flared period, and timely watering can promote corn ear development and normal pollination.
Scientific fertilization adopts formula fertilization technology. The base fertilizer is mainly organic fertilizer with appropriate amount of nitrogen, phosphorus, and potassium fertilizer. The top dressing is mainly nitrogen fertilizer, which is mainly applied in the jointing and booting stages, and appropriate top dressing in the later period. Strengthen the control of pests and diseases during corn tasseling and silking, pay attention to the control of corn borer and aphids, and chemical control mainly depends on spraying.
