During the corn pollination period, if the pollination effect is not good, artificial pollination can be used, which can make the corn particles round and complete, and achieve the effect of increasing yield and quality. What's the way to pollinate corn? What should we pay attention to when pollinating? Let me share it with you below. 1. Corn pollination method
1. Collecting pollen
The first time of artificial pollination is to collect pollen. First, find a container, put the container close to the corn tassel, and shake it gently Tassel, shake off the pollen into the jar. Then sort the collected pollen and remove the pollen sacs, chaffs and other impurities inside, so that the pollen is collected. Pollen should be used in time after collection, usually at 8-9 o'clock in the morning on a sunny day. If the water content is too high if collected too early, the pollen will easily clump, which is also not conducive to pollination.
2. Pollination
The pollination time is generally from 8:30 to 11 o'clock in the morning, which is determined by the temperature conditions. When pollinating, the pollination period should be used and the pollen should be lightly sprinkled. On the filaments, pollination takes place. Generally, we should carry out three pollinations for female ears, each in the early stage, peak stage and late stage of silk spinning, so as to ensure the fertilization and conclusion of pollen more quickly.
3. Other pollination methods
The previous pollination method has a high pollination rate, but when the workload is heavy, it is time-consuming and laborious. You can directly shake the corn plant to let the pollen fall. Or find a rope, and two people work together to gently shake it in the corn field to let the pollen fall in the field. The pollen falling on the filaments is artificial pollination. Although this kind of pollination is convenient, it is not as good as collecting it. Pollen followed by pollination. 2. Frequently Asked Questions about Artificial Pollination of Corn
1. 5-7 days after the corn is emasculated, the female ear will gradually spin silk. This process will last for about 5-7 days, and 2 days after the corn filaments spin out. -Pollination is best within 5 days, and the pollination product rate is high at this time.
2. The pollination time is finally carried out from 8 to 11 o'clock in the morning on a sunny day. There should be no dew in the field at this time. If it is too early, dew will affect pollination.
3. It is not suitable for pollination when the temperature is higher than 35 degrees.
4. It is best to collect pollination now and then collect it after pollination to avoid collecting too much pollen at one time, which will lead to sedimentation, death of pollen and harm to pollination.
