Methods and matters needing attention of Corn castration

The management of the ear stage of corn is related to the yield of corn, and at this time, there is a technology that can increase the yield, that is, castration, many wonder whether corn castration can really increase the yield. In fact, according to the actual production proof, emasculating can increase the output by 5% and 8%. So how can corn go to male? What do you need to pay attention to when you go to the male? Let's take a look.

1. Time of castration

When the male ear exposed the apical leaf 6-7cm and did not disperse the powder, it was the best to castrate the male ear, and the effect of increasing yield was obvious. This is because the stem of the male ear is brittle and tender, and the adhesion of the stem node of the male ear is not firm, and it is easy to pull out. If you wait for it to grow and develop for a period of time, the stem will be aged and the stem node will stick firmly. At this time, it is not easy to pull out the top leaf, and the stem is easy to be pulled out, which not only can not achieve the effect of male removal, but also will affect the yield. To go male, you should choose a sunny day, but avoid the time of strong light, so the best time is usually in the afternoon or afternoon, when the sun is bright but not strong, so the temperature is suitable, and the wound is easy to heal after castration, so as to avoid being infected by germs. do not go male on cloudy and rainy days, so as not to cause the ear to rot and die.

2. Castration method

It is also necessary to master the method when emasculating, and should not be carried out blindly, otherwise it will be counterproductive, such as castration between lines or plants to remove the unflowering male spike, so that the normal pollination between plants will not be affected. Maize has more male ears and produces more pollen, which is mainly transmitted by the wind, and the respiration of pollen is very strong, which will consume a lot of plant nutrition and compete with female ears for nutrients, resulting in poor growth of corn. Therefore, the removal of part of the male ear, not only will not affect the growth of corn, but also avoid unnecessary nutritional consumption. After the pollination of the plant, all the male ears can be cut off, the nutrient consumption can be reduced, and the nutrition of the plant can be concentrated on the female ear, so that it can grow and develop rapidly and increase its yield.

3. Matters needing attention in castration

In castration, we should be careful not to cut off the leaves of the plant, otherwise it will affect the photosynthesis of corn and reduce the synthetic nutrients of corn, so that the yield can not be reduced and the yield can not be increased. In addition, attention should be paid to the time of emasculation. the male should be removed in time, too late, and the effect of increasing production is not obvious. if the male is removed, the male ear on the edge of the ground and on the ground should not be removed.

The above are the methods and precautions of corn emasculation. I hope I can help you. If you want to know more about corn planting, please follow us.
