What should I do if the corn is not strong?

Corn is grown in many places in China. It is one of the important food crops and cash crops. Let’s share with the blow today that corn is not strong.
If the corn is not strong, it should be done:
During the corn harvest season, it was found that there were no corn cobs on the corn poles of some fields. Some of the ear sides had no seeds from the base to the top, and the ears were bent to the side of the missing grains to form banana mites; some had no granules at the top, and some were bald. Some have no grain at the tail, and are bald-tailed; while some of the whole ear has only a few scattered and scattered, and severely forms an empty ear. According to the analysis of relevant experts, this phenomenon is considered that the nutrient supply in the ear of the ear is insufficient, and the topdressing is carried out reasonably.
Control the temperature. If the temperature before and after corn heading is higher than 35 °C, the corn pollen is killed, affecting fertilization, resulting in failure to be normal. The temperature at the late stage of grain filling is lower than 16 °C, which affects the accumulation of dry matter and causes granules. Water imbalance can also cause a decrease in pollination quality. Controlling watering is important. In heavy rain, when the flowers are scattered, the tassels cannot bloom normally, and some pollen expands and ruptures or sticks into a group and loses vitality, which affects the normal conduct of pollination and fertilization. From the big bell to the flowering stage, if the drought occurs, the tassels will be slowed out or the tassels will be dried up, resulting in a significant reduction in pollen and disproportionate. Therefore, spraying new high-fat membrane insulation before and after heading can alleviate the evaporation of water in dry weather.
