When the corn is about to be harvested, correctly grasping the harvest period of the corn is an important production link to increase the grain weight, reduce the loss, and increase the yield and quality. The proper late harvest of the corn can not only prolong the grain filling time but also increase the corn yield. Because corn is only fully mature, the grain weight is the highest and the yield is the highest. The harvest is early, the maturity is poor, the grain weight is low, and the yield is reduced. In some places, there is a habit of early harvesting, which is often harvested when the leaves of the ear are just white. At this time, the 1000-grain weight is only about 90% of the ripening period, and the yield is usually reduced by about 10%. Corn is harvested in a timely manner, and the yield per mu can be increased by more than 100 kg. The corn yield is reduced early, do you know? Corn harvest period - the misunderstanding of farmers 1. Do not understand the perfect period: The maturity of maize needs to go through three stages: milk ripening, wax ripening and ripening. Because corn is different from other crops, the grain is born on the ear, and it is not easy to fall off after maturity, and the post-ripening effect can be completed on the plant. Therefore, the ripening period is the best harvest period for corn. 2. Follow blindly at harvest: 1) Blindness caused by different growth periods of breeds: Products with early growth period have premature symptoms (yellow stalks turn yellow). Farmers who planted later in the growing period blindly harvested from the wind. 2) Blind obedience caused by different planting time: the same planting time is different in the same maturity period, and the maturity time is different. The maturity of early sowing is early, and the late sowing is late in maturity. Some farmers see the harvest of others and blindly harvest. 3) Blind obedience caused by diseases: Although different products have the same growth period, some products do not resist disease (big spot disease / bacterial wilt), which causes the plants to dry out prematurely. These farmers harvested, and the farmers who did not get sick began to blindly harvest. 4) Blind obedience caused by mechanical coordination: Although some farmers instructed the corn not to be late, the harvesting machine began to harvest in the village, and there was no harvesting machine in the later stage, so blindly harvested. Corn harvest - farmers worry 1. Worried about corn lodging: If it is not harvested after the ripening period, the support of the corn stalk is reduced, the plant is easy to fold, and the lodging of the ear causes the mildew to contact the ground. These farmers are not able to judge the corn glutinous rice when they are ripe, and they are worried that the corn will fall and harvest in advance. 2. Worried about the late corn climate: If you don't harvest in advance, wait for frost or snow when you are finished. 3. Worried about the loss of corn kernels: When the corn is ripe, some varieties have serious grain loss during harvest. The best time for corn harvest The ripening period is the best time for corn harvesting: the ripening of corn undergoes three stages: milk ripening, wax ripening and ripening. The maturity period mark: the milk line disappears and a black layer appears at the bottom of the grain. What is milk line? The milk line is the boundary between milky white and dry matter formed during the process of corn grouting, when dry matter accumulates from the outside to the inside of the corn kernel. When cooked, the milk line disappears and a black layer appears at the bottom of the grain. How much does the corn yield early? According to the research, if the income is 3 days early, the yield reduction is 4%. If you receive 9 days early, you will reduce production by at least 10%. do you know?
