What management measures are there after corn lodging?

1. For corn that has lodged only slightly (the angle between the stalk and the ground is greater than 45°), there is generally no need to take measures to straighten it; let it stand upright naturally as it grows. If corn lodges before the booting stage, do not move it and do not prop it up. Within 3 days after lodging, it can naturally bend back up. The stem nodes near the ground quickly take root. Because the root mass increases, there will be no second lodging, and there is no impact on yield. Once it is propped up, the roots will inevitably be damaged, and it will no longer take root, which not only affects yield but also makes a second lodging likely.

2. For corn that has lodged severely, especially if it is lying flat, it should be manually straightened in good time, and soil should be banked around the roots. The straightening method should be done by two people working together, one straightening and one banking soil; the soil should be banked to a height of 7-8 cm, and after banking, it should be pressed firm with the foot. If corn lodges after heading, do not cut the leaves and do not remove the top. It can only be propped up and tied in bundles. When tying in bundles, tie the ears above the rope, and do not tie the ears below it. The best number per bundle is 3-4 stalks. Do not exceed 5 stalks; if more than 5, it is easily broken in another storm. When tying in bundles, tie them tightly and do not let them loosen. As for the timing of tying in bundles, if it lodges that day, finish tying it that day. At most, it must not exceed 3 days. After 3 days, it can no longer be propped up; propping it up again will damage the roots and instead reduce yield even more.

3. For corn with broken stalks, remove the broken plants from the field as soon as possible to prevent them from rotting and affecting the growth of normal plants. Han Lihua
