Corn harvest should be timely
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. 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, a large amount of nutrients in the plant is also being transported to the grain and accumulated in the grain, and the grain still contains 45% to 70% of water. At this time, the harvested corn drying will take a lot of time and labor. After drying, the weight of a thousand grains will be greatly reduced. According to experiments, the harvest of corn in the milk-mature stage can generally reduce production by 2 to 3 percent, and the quality is also significantly reduced. The best time for corn harvest is the ripening period. At this time, the 1000-grain weight and yield of corn can reach the highest. Under normal circumstances, the main characteristics of judging the maturity of corn are as follows: corn glutinous leaves are yellow, white, loose, and the grains become hard and shiny. The inherent characteristics of the varieties are “dairy†disappearance, black layer at the tip of grains, and water content. It fell below 33%; for the time being, the harvest period was about 50 days from the flowering and booting stage of maize. At present, many of our peasant households sow wheat and rapeseeds for early cultivating, and some harvest them during the milk ripening period. The milk ripening period is usually 10 to 15 days before the ripening period. At this time, the harvest will inevitably cause serious damage. Reduce production and reduce income. The varieties of maize that have been popularized in recent years are all good in disease resistance, and generally the live trees are mature. Even if the grains completely stop growing, the plants still maintain the green branches of green branches when they mature. Therefore, corn grain maturity cannot be judged simply based on the extent of stem yellowness. Maize maturation should be based on the color of the loquat, the hardness of the grain, whether the shiny keratin, whether the handkerchief dent, the disappearance of the grain milk line, the appearance of the black layer to comprehensive judgments. In short, to seize the bumper harvest of corn production, timely harvesting is an important measure that does not require any investment but can greatly increase production efficiency. To this end, we must master the main characteristics of corn maturity, seize the best harvest time of different varieties, and achieve scientific arrangements, and orderly and timely harvest, in order to ensure increased production and reduce unnecessary losses. If it is really necessary to harvest in advance, it is recommended that farmers should take poles for harvesting to make the corn mature on the straw, so that the impact on the yield will not be too great.
