When corn is about to be harvested, correctly grasping the harvest period of corn is an important production link to increase grain weight, reduce losses, and increase yield and quality. When maize is harvested at the right time, it can increase yield by more than 100 kilos per mu. Then how do we grasp corn? What about the harvest? Today we will tell you how to determine the best harvest time for corn.
First, look at the growth characteristics of corn and determine the best harvest period for corn. Maize maturation 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 milk
The ripening period will be harvested prematurely. At this time, a large amount of nutrients in the plant is being transported to the grain and there is still 45%-70% of the water in the grain. At this time, the harvested corn drying will cost a lot of time, and it will be dried after a thousand major grains. reduce. According to experiments, harvesting during milk ripening can generally reduce production by 20% to 30%, and the quality is significantly reduced. If you do not harvest after the ripening period,
At this time, the supporting power of corn stems is reduced, and the plants are easy to infuse. The fallen ears cause mildew when they touch the ground, and they are also vulnerable to the damage of birds and produce undue losses in yield and quality. Whether or not corn enters the ripening stage can be seen from the appearance characteristics of the normal maturation of the plant: the middle and lower leaves of the plant turn yellow, based on
The leaves were dry, the yellow leaves of the ear were yellow and white and loose, the grain milk line disappeared, the black layer appeared, became hard, and exhibited the inherent color of the species.
Second, calculate the time, determine the corn harvest period, under normal circumstances, according to the corn growth period is extended about 10 days for harvesting is appropriate. For example, Zhengdan 958 has a growth period of 96 days. It can start normal seeding and the soil can normally grow and grow for about 10 days, and harvest about 106 days. If sowing time is June 1st,
Harvested around September 17th.
3. Dry the skin immediately after harvesting, and do not stack it after harvesting. After harvesting, collect the skins or bring the skins to the rods to transport them home. Use the artificial skin to dry the skin in time. It can also promote the new type of corn tanned skins for molting, which can save a lot of labor. How to determine the best corn harvest is introduced here, because of the late harvest of corn
The amount of water is generally about 30% to 40%. You can listen to the weather forecast and dry in sunny weather. When the moisture content is 20% to 30%, promptly carry out threshing and drying. It is advisable to dry the corn to a moisture content of 14% or less.
