Preventive measures for poor fruiting of corn

In the process of corn planting, corn seed failure often occurs, which seriously affects the yield and quality of corn and brings huge losses to farmers. Then in order to safeguard the interests of farmers, we must take preventive measures against poor fruit. Let's take a look at it together with Xiaobian.

1. Select good seeds

Corn has certain regional characteristics for soil, environment and cultivation conditions, so if it is not suitable for local planting varieties, it will have poor seed setting. Therefore, according to the local soil, climate and cultivation conditions, we should select good quality with strong resistance and high yield to reduce poor fruiting phenomenon.

2. Early sowing in due course

Corn heading in high temperature climate, high temperature makes his pollen vitality reduced, pollination quality is poor, so sowing early in time, so that corn heading period to avoid high temperature climate, let it pollinate in a suitable climate. At the same time, according to the variety characteristics of corn, reasonable close planting, enhance field permeability, improve leaf photosynthesis, increase ear nutrition, promote ear differentiation, improve seed setting rate.

3. emasculation

The female ear of maize is generated by axillary bud, so it grows weakly and differentiates later, while the male ear is developed from terminal bud, grows strongly and differentiates earlier. Therefore, when the external environment is not good, the phenomenon of uneven nutrient absorption of male and female ears will occur, and the male ears will inhibit the growth of female ears, resulting in poor corn seed setting. Therefore, proper emasculation should be carried out at the tasseling stage of corn to reduce the top advantage of corn, promote the growth and development of female ears, and at the same time combine artificial pollination to improve the seed setting rate.

4. Strengthen fertilizer and water management

Corn in fertilizer and water shortage, will also affect its seed rate, so in the heading period is if the drought climate, to timely watering to promote the development of ears, so that its normal pollination fertilization. At the same time, timely fertilization should be promoted. The principle of applying sufficient base fertilizer, light seedling fertilizer, heavy jointing fertilizer and clever seed fertilizer should be adopted. The base fertilizer should be mainly organic fertilizer, matched with appropriate amount of nitrogen, phosphorus and potassium fertilizer. The top fertilizer should be mainly nitrogen fertilizer, generally carried out at jointing stage, so as to promote corn growth, improve seed setting rate and lay a foundation for high yield.

The above is an introduction to preventive measures for poor corn bearing. I hope it can help you. If you want to know more about it, please pay attention to us.
