When do you break the corn?

The harvest period of maize has a great influence on the yield and quality of maize. Under normal circumstances, people are used to harvesting when the ear of corn is yellow and the upper grain is hard. In fact, at this time, the corn is in the wax ripening stage and has not yet fully matured. During this period, not only will the corn yield be reduced by 8- 10%, but also the flour yield will be low and the quality will be poor.

The sign of complete maturity of corn is that the milk line of the grain disappears, the grain becomes hard, slightly dry and sunken, and the bracts of the ear are dry, white and loose. Milk line appears 28-30 days after maize flowering and pollination. When the starch is fully deposited on the top of the grain and begins to form solid, and the lower part is still milky white liquid, the solid-liquid interface forms a line from the outside, which is the milk line. Corn goes through three periods from the appearance of milk line to its disappearance: formation period, half milk line period and milk line disappearance period, about 20 days.

In many cases, farmers harvest corn at the half-milk line, when only 90% of the corn kernels are fully mature. After the half-milk line stage, corn grains continued to fill, and the 7- 10 Tian Ru line disappeared. At this time, the 1000-grain weight of corn seeds reaches the maximum, and the harvested corn has the highest yield and the best quality. Therefore, under the premise of not affecting the sowing of the next crop, corn should be harvested as far as possible until the seeds are completely mature, so that corn can obtain higher yield and excellent quality, and thus obtain higher income.
