1. For corn that has a lighter lodging (greater than 45 in stem and ground angle), it is generally not necessary to take straightening measures to allow it to stand up naturally as it grows. Corn is lodging before the booting stage and it is immobile and cannot be helped. Within 3 days after lodging, it can be folded naturally. The stem sections near the ground quickly take root. As the root volume increases, there will be no secondary lodging and no effect on the yield. Once raised, it will inevitably be rooted, and will no longer take root. It will not only affect production, but it will be prone to secondary lodging.
2. For the serious lodging, especially the stubborn corn, artificial straightening should be carried out in time, and soil should be cultivated in the root. The method of straightening should be coordinated by two people. One is to straighten up the soil, and the other is to cultivate the soil. The height of soil should be 7-8 cm. The corn is laid down after heading. Do not cut the leaves. Can only lift up the bar. When you tie the handle, tie the ear of the fruit to the rope. Do not prick the ear to the bottom. The best number of ties is 3-4. There must be no more than 5 trees, more than 5 trees, and even a storm breaks easily. When you tie your tie, you must tie it tightly. Do not loosen it. The time required to tie it is that the day falls and the day is finished. Can not exceed 3 days. After 3 days, they can no longer support them. Instead, the root causes more damage.
3. For corn with broken stems, remove the broken plants from the field as soon as possible to avoid rot and affect normal plant growth.
