The latest preventive measures for poor fruiting of corn

The poor fruiting of corn often occurs in the process of corn planting, which seriously affects the yield and quality of corn and brings huge losses to farmers. Well, in order to safeguard the interests of farmers, we must take good preventive measures against poor health. Let's take a look at it with the editor below.

1. Select improved varieties

Corn has a certain region for soil, environment and cultivation conditions, so if it is not suitable for local planting varieties, there will be a phenomenon of poor fruiting. Therefore, according to the local soil, climate and cultivation conditions, the good quality with strong stress resistance and high yield should be selected to reduce the bad fruiting phenomenon.

2. Timely early sowing

Corn heading in high temperature climate, high temperature reduces its pollen vitality and poor pollination quality, so it is necessary to sow early when sowing, so that the heading stage of corn can avoid high temperature climate and pollinate in a suitable climate. At the same time, according to the characteristics of maize varieties, reasonable close planting, enhance the permeability of the field, improve leaf photosynthesis, increase ear nutrition, promote ear differentiation, improve seed setting rate.

3. Castration

The female ear of maize is generated by axillary bud, so the growth is weak, the differentiation time is late, while the male ear is developed from the terminal bud, the growth is strong, and the differentiation is relatively early. Therefore, when the external environment is inappropriate, there will be a phenomenon of uneven nutrition absorption of male and female ear, male ear will inhibit the growth of female ear, resulting in poor fruiting of corn. Therefore, in the male stage of maize, it is necessary to properly remove the male, reduce the apical advantage of maize, promote the growth and development of female ear, and improve the seed setting rate combined with artificial pollination.

4. Strengthen the management of fertilizer and water

Corn in the lack of fertilizer and water, will also affect its seed setting rate, so in the heading stage is in case of dry climate, timely watering to promote ear development, so that its normal pollination and fertilization. At the same time, it is timely to popularize fertilization, according to the principle of sufficient base fertilizer, light seedling fertilizer, heavy jointing fertilizer and skillful application of seed fertilizer, the base fertilizer is mainly organic fertilizer, with an appropriate amount of nitrogen, phosphorus and potassium, and topdressing is generally based on nitrogen fertilizer, which is generally carried out at the jointing stage to promote the growth of maize and improve the seed setting rate. lay the foundation for high yield.

The above is the introduction of preventive measures for poor fruiting of corn. I hope it can help you. If you want to know more about it, please follow us.
