The maturation of corn needs to go through three phases: milk ripening, wax ripening and ripening. Due to the difference between corn and other crops, the seeds are planted on the ear and are not easy to fall off after ripening, and ripening can be accomplished on the plants. Therefore, the ripening period is the best harvest period for corn; if silage is carried out, it can be harvested as early as possible at the end of wax ripening or ripening early. Harvesting too early or late will reduce the yield and quality of corn. Correctly grasping the harvest period of corn is an important measure to ensure high quality and high yield of corn. If the milk ripening period is harvested prematurely, then a large amount of nutrients in the plant is being transported to the grain, and the grain still contains 45% to 70% of water. At this time, when the harvested corn is drying, it will cost a lot of time, and it will be dried after 1000 grains. Decreased, according to the test, milk production can generally reduce the yield of 2 to 3 percent, and the quality was significantly reduced. If not harvested after the ripening period, the supporting power of the corn stalks will be reduced, the plants will be easy to invert, and the ear of the lodging will cause mildew when it touches the ground, and it is also vulnerable to damage from birds and animals, causing undue loss of yield and quality. Therefore, it is very important to correctly grasp the harvest period of corn. At present, in many places, wheat is sown for early harvest, and some are harvested during the milk ripening period. There are usually 10 to 15 days before the ripening period until the ripening period. At this time, the harvest will inevitably result in serious reduction in yield and income. Whether corn enters a fully mature period can be seen from the appearance characteristics: the middle and lower leaves of the plant turn yellow, the base leaves dry, the leaves and leaves of the ear become yellow-white and loose, the grains harden, and the inherent color of the variety is exhibited.
