Late harvesting technology of corn is a good technology for benefiting farmers and farmers. Popularizing and applying late harvesting technology of corn, correctly grasping the harvest period of corn and lengthening the filling time is to increase 1000-grain weight, increase corn yield and quality, realize grain yield increase, increase farmers’ income and An important part of agricultural efficiency.
