Lead: I first knew this technology. I came from a conversation with the salesman. I talked about a corn stick with a few sticks. The reason is that corn pollination is not good. The salesman wondered, pollination is not good, then do you want to pollinate the corn? Then I was asked, and an experienced agrochemical teacher at the scene shared this article and studied together.
Corn is a hermaphroditic crop, and the same plant male flower (small flower) is opened three days earlier than the female flower (corn cob) to avoid self-pollination of the plant. In natural conditions, the natural hybridization rate is about 95%. For example, artificial forced self-crossing (the pollination of this plant) is less fruitful and the grain is thinner, resulting in a large decrease in yield. Therefore, the use of septum or interlaced emasculation can increase corn yield by about 10%.
The emasculation effect of the isolates is better than that of the interlaced emasculation. Because the detached plants can be artificially regulated, the anterior and posterior adjacent plants of the emasculated plants are male plants, which increases the chance of pollination by different plants. When the male flower (small flower) is pulled out from the heart leaf by about half, it should be pulled out by hand, and the plants on the side and the ground should not go to the male. The male stalks that are pumped out are often lurking with corn mash, so the male flowers that are extracted should be thrown out of the field or buried deeply to prevent the corn mash from crawling out and harming the corn. The emasculated strain of the whole corn field is generally not more than one-half of the total number of plants, in order to prevent poor pollination and affect seed production and yield.
Corn emasculation
After the male flowers are finished, the photosynthesis is extremely weak. It relies on the photosynthesis products of the leaves to survive, and like a parasol, it covers about 20%-25% of the sunlight to the whole field. Reduces the photosynthetic function of the leaves. After pollination, the male inflorescences are cut off with a sickle--"cutting the top", which can make the corn early maturing and increase production.
