In the late autumn of Daejeon crops, there were three cases of lodging, stem fall, and stem fold. Due to the difference in lodging conditions, the degree of output loss varies. Generally speaking, the stem is only the tilt of the crop stem, until the weather improves, after a period of time will grow upright on its own. Stem folding refers to the broken stalk, which is generally difficult to restore growth, and it is not easy to take rescue measures. The roots will cause the lateral roots of the crops to be lifted, the angle of stalks to fall, and even the leaves and ears attached to the ground, the water content will decrease slowly, the light will be less, the photosynthetic intensity will be weakened, the yield will be reduced, and the ripening time will be prolonged. If necessary treatment measures are taken, Will reduce the loss to a minimum.
In the late stages of corn growth, lodging is mostly rooted. Because the upper part is heavier, the plants are difficult to stand upright and must be raised immediately after the storm. The longer the time delay, the heavier the reduction in production. When lifting, make the stem and the ground form an appropriate angle. If it is too straight, the damage will be more severe. Tests have shown that the proper angle of the corn roots is 30 to 50 degrees, and the earlier the picking time is, the better. The roots of the corn should be well cultivated at the same time.
The roots of sorghum can be bundled immediately. Three to five plants are bundled together with the stalk's own leaves. The two intersections are tied in the upper part of the plant so that each plant has a certain degree of inclination, and the spikes do not overlap. Pressure, to cross open. Minimize the use of leaves when bundling and protect the functional leaves of the lower part of the ear from loss. The sooner you can help, the better. It cannot exceed two days.
If the roots of the millet are damaged during the later period of growth and development, the stems will be tiled on the ground, and the roots will be dead and the disease will spread to reduce the yield. According to the test, using sticks to pick up the leaves on the ground, instead of raising the yield per mu, increased 25 kg per mu from the 60-degree angle raised on the day after the storm. It can be seen that the former method has less wounds, quick seedlings, and high yields. If the lodging is lighter, topdressing and cultivating can be carried out to minimize the loss of production.
