How to determine the sowing date of summer corn? Please give guidance as the growth period of corn available in summer corn area is limited, in order to strive for enough heat to make corn fully mature, harvest in time, obtain higher yield, and not miss the normal sowing of wheat in the following crop, so the sowing time of summer sowing corn is required as early as possible. That is, immediately after the winter wheat harvest, hanging ploughing and killing stubble, then sowing, or sowing with the hard stubble seeder immediately after the harvest of wheat. According to the experiment, each early sowing day can prolong the filling period by one day, increase the grain weight and increase the yield by 2.5%. In order to sow early, in some places where heat resources are slightly lacking, summer sowing corn can also be interplanted in the wheat bank 10 minutes before the wheat harvest, and then irrigated with wheat yellow water to promote its early emergence. By the time of wheat harvest, the corn has already emerged and has grown 2 Mel and 3 leaves. However, the practice of interplanting is not easy to grasp the seedling density, and then harvest wheat after emergence, which is easy to cause seedling injury, especially in mechanical harvesting, and it is difficult to reach the whole seedling.
