The proper late harvest of corn is harvested when the corn is fully ripe, and its physiological characteristics are as follows. (1) Growth time. It is more convenient to calculate pollination on the day of flowering and pollination. Generally, it is harvested 50 to 55 days after pollination by Yanghua. The late-maturing varieties with long growing period are limited by the limit, and the early-maturing varieties with short growing period are capped by the upper limit. In the case of low temperature and rainy weather during grouting, the light is insufficient, the grain filling period will be prolonged, the maturation period will be postponed accordingly, and the harvest period should be postponed accordingly. (2) Loquat characters. Loquat leaves turn white and loose to harvest. (3) Grain characteristics. The seeds harden and the round sticks do not sag with their fingers. (4) The milk line disappears. Cut off the corn on the grain color of the section, and the clear yellow-white boundary line formed by the grouting progress in the middle and lower part of the grain is the milk line. The maturity of the milk line near the cob is higher, until the disappearance is completely mature, and the yield is highest at this time. Good harvest.

Insufficient light during corn filling period should be appropriately late
In recent years, the harvest of corn in most plots is early, which is not conducive to high yields. Appropriate late harvest of corn is a simple, easy-to- increase technology that does not increase costs. This year, the corn filling period is cloudy, and the lack of light is not conducive to the photosynthesis of plants, and it should be collected late.
