Management measures of lodging corn

The main results are as follows: 1. For the corn with light lodging (the angle between the stem and the ground is more than 45 °), it is generally unnecessary to take straightening measures to make it stand up naturally with its growth. Corn lodging before booting stage, immovable, unable to help. It can fold up naturally within 3 days after lodging. The stem nodes near the ground take root quickly. Due to the increase of root quantity, there will be no second lodging, which has no effect on the yield. Once picked up, it is bound to hurt the root, and no longer take root, not only affect the yield, but also prone to secondary lodging.

2. For serious lodging, especially for creeping corn, artificial straightening should be carried out in time and soil should be cultivated at the root. The method of straightening should be supported by two people, one should be straightened, and the other should cultivate the soil. The height of the soil should be 7 to 8 centimeters, and the soil should be firmly footed after cultivation. Corn lodging after heading, do not cut leaves or head off. You can only pick it up and tie it up. When tying the handle, tie the ear to the top of the rope, not to the bottom. The best number of bundles is 3-4. No more than 5 trees, more than 5 trees, easy to break in case of storm. Fasten the handle tightly and not loosen it. The time required to tie the handle is required to fall on the same day and finish on the same day. No more than 3 days at most. If you can no longer help after 3 days, the yield will be reduced even more if you hurt the root again.

3. For the corn with broken stem, the broken plant should be cleared out of the field as soon as possible to avoid rot and affect the normal plant growth. Han Lihua
