Maize is an androgynous plant with different flowers, and the same plant male flower (smallpox) is opened three days earlier than the female flower (cob) to avoid pollination from the plant. In natural conditions, the natural hybridization rate is about 95%. If artificially forced self-crossing (self-pollination) results in less fertility and a smaller grain, the yield is greatly reduced. Therefore, using septa or emasculation measures, corn production can increase by about 10%. The septum sterilizing effect is better than the emasculation of the septum, because the septum emasculation can be artificially regulated, so that the adjacent plants of the emasculated plant are both male and female, which increases the chance of alien pollination. The detassel should be drawn by hand when the male flower (smallpox) is drawn from the heart and leaves, and the plants on the side and in the field must not be emasculated. Male larvae are often lurking in the stems of the male flower. Therefore, the males that have been pumped out should be thrown out of the field or buried deep to prevent the corn borer from climbing out and harming the corn. The emasculated strains in the whole corn field are generally not more than one-half of the total number of plants in order to prevent poor pollination and affect seed production and yield. Male male inflorescence, after all the male flowers have been opened, is extremely weak in photosynthesis, and it relies on the product of leaf photosynthesis to survive, and as a parasol, it covers about 20%-25% of the sunlight to the whole field. Reduces the photosynthetic function of the blade. The pollinated male inflorescence is cut off with a trowel – “cutting the topâ€, which can make the corn earlier and increase production.
