Late crop lodging
Daejeon crops later fell three kinds of conditions: fallen stems, roots down, stems folded. Due to the difference in lodging conditions, the degree of output loss varies. In general, the stem is only the tilt of the crop stem, until the weather improves for a period of time after the growth will self-recover the upright state, therefore, the lodging yield loss is lighter. Stem folding is the broken stalk, which is generally difficult to restore growth, and it is not easy to take rescue measures, resulting in a large loss of output. The roots will pull up the lateral roots of the crop, and the angle of stalks will be tilted. Even the ground will be tiled and the leaves and ears will be attached to the ground. The water will slow down, the light will be less, and the photosynthetic intensity will be weakened. This will reduce the yield and prolong the ripening time. When this kind of lodging occurs, taking the necessary supportive measures will minimize the damage. In the later stages of maize growth, roots often fall. 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. In support, the stems should be properly angled to the ground. To help straighten, more damage will increase production. Tests have shown that the proper angle of the corn roots is 30 degrees to 50 degrees. The earlier the picking time is, the better, and the roots of the corn should be cultivated well at the same time. The roots of sorghum can be immediately taken care of. The stalks are bundled with 3 to 5 stalks. The two intersections are tied in the upper part of the plant so that each plant has a certain degree of inclination. Overlapping extrusions, 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. Do not take this measure for more than two days. The roots of the millet have fallen in the later stages of the childbirth. The stems are easy to lay on the ground, and the roots are rotted, the disease is spread, and the yield is reduced. According to the test, using sticks to pick up the leaves on the ground, instead of raising the yield per mu, increased 25 kilograms 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.
