Corn planting techniques: what are the methods of promoting summer corn ripening?

What are the methods to promote the ripening of summer corn? Please introduce that the ripening promotion of summer corn can be carried out by the following methods: 1. Peeling the bracts and drying ears: when the corn begins to harden in the middle stage of wax ripening, the bracts of the corn are gently peeled off one by one, so that all the grains are exposed and let the sun shine directly. In general, peeling and drying for 15 to 20 days, the grain water content can be reduced by 14% and 18%, and the early maturity is 5 days. However, it should be noted that the live and mature varieties should not be peeled. 2. The method of removing diseased old and residual leaves: in the late growth stage of maize, most of the middle and lower leaves aged and died. Eliminating them in time can not only increase ventilation and light transmittance in the field, reduce oxygen consumption, reduce disease infection, but also accelerate grain ripening and increase yield. 3. Remove invalid ear and invalid plant: single ear corn variety, only the upper first ear is left, and the lower invalid ear is removed. Pull out the empty stalks, diseased plants and other ineffective plants in the corn field in time. 4. The method of cutting off the top tip in batches: according to the maturity of corn in the field, the top leaves of the upper ear which entered the wax ripening stage were cut off in batches. This method has a certain effect on the yield, the earlier the cutting, the more the yield will be reduced, so the top cutting should not be earlier than the early stage of wax ripening, and two large leaves should be left above the ear to facilitate photosynthesis and supply the nutrients needed by the plant.
