The mechanized harvest time of soybeans is demanding. The harvest is too early, the grain is not yet fully matured, and the 100-grain weight, protein, and fat content are all low. If the harvest is too late, the soybean loses too much water, and it will cause a lot of fried grains. Therefore, we must accurately grasp the timely harvest of soybeans. The appropriate harvest period varies depending on the harvesting method. The most suitable period for direct harvest is at the beginning of ripening. During this period, all the leaves of soybeans were detached, stems, pods, and grains all showed the color of the original varieties. The moisture content of the seeds had dropped to about 20-25%, and shaking the plants by hand would produce a crisp sound. If using the method of segmental harvesting, it is necessary to advance the harvesting period appropriately. It is generally considered that the yellow ripening stage is the best harvesting period, during which period the soybean leaves fall off by 70-80%, and if possible, the segmental harvesting is adopted. The beans begin to turn yellow, and some of the pods turn into primary colors. Individuals still appear blue. This is the most suitable time for cutting the sun. To cut the sun prematurely, due to the large water content of the stem leaves, it is impossible to pick up the earthworms, green grains, and mildew. On the other hand, if the sun is cut too late, the significance of sub-harvesting is lost.
