According to reports, corn production is closely related to the harvest period. If it can be harvested in the best period, it can increase corn production by 5-10%. Conversely, harvesting too early or too late can affect production. Corn is frosted at the ripening stage, and its kernels can continue to gain weight, and the highest weight of 100 grains occurs when the leaves are green for 7-10 days. The main characteristics are: yellow leaves at the base of the plant, white and loose leaves of the fruit, hardened seeds, black canopy production, and harvesting when the milk line disappears. According to the experiment, corn can be harvested 9-12% more during the ripening period than during the wax ripening period, which is 3% higher than the wax ripening stage. Because the ear of corn is wrapped with eucalyptus leaves, it can resist low temperature and light frost, and should be harvested properly late. It can promote the ripening of corn and achieve the purpose of increasing production.
