Analysis of soybean growth in the later period in North China (10.3)

After entering September, soybean in Northeast China has entered the final growth stage At present, the overall climate conditions in this area are basically normal, but there has been another drought in the west of Heilongjiang and Jilin provinces and the east of Inner Mongolia recently At the same time, during September 3-4, due to the influence of cold air, frost weather has appeared in Heilongjiang and some parts of Northern Inner Mongolia, but the influence range is not large Although the number of soybean pods in Northeast China increased significantly after the drought was relieved in August, the new pods are still far away from maturity at that time Under the situation that frost period is approaching and frost may occur at any time, the obvious recovery of soybean yield in Northeast China is impossible According to the forecast of the meteorological department, in the middle of September, the northern part of Heilongjiang and most of Inner Mongolia, and in the first ten days of September, the first frost will appear in some areas The first frost appeared from late September to early October in most parts of northeast, central and eastern North China and Northwest China Because the first frost day in the northeast is later than that in the whole year, it is beneficial to the growth of some pods in the last stage However, the meteorological department also predicted that the rainfall in September in most of the Northeast will be more than that of the whole year, which may have a greater impact on the water content of soybean As the soybean growth period is generally delayed due to drought, if there is more rainfall before the harvest period, the problem of high ratio of green beans and water content will appear again this year Xcc (author:)
