Replanting summer corn in Northeast China is already too late; is there still time to replant Chinese cabbage now?

Due to the drought in Northeast China this year, corn seedlings in many areas have emerged slowly, and in many areas the corn has even failed to emerge. Of course, some farmers have also been forced to postpone and delay sowing corn because of the drought. For corn in Northeast China, sowing is generally done in April and May, and now that June has already arrived, can it still be sown? Science Agriculture will give you a brief explanation.

For corn, the growth period in the Huang-Huai-Hai region is generally around 100 days, while for some early-spring corn with a longer growth period, the growth period may be as long as more than 120 days, that is, 4 months. However, for most corn, the growth period falls within the range of 95-110 days. In Northeast China, the temperature is on the cold side, and the overall growth period when sown in early spring is still basically around 100-plus days even so, which is to say that sowing at this time means the crop cannot be harvested until mid-September.

If sowing in Northeast China at this time, one needs to look carefully at the actual climate conditions. For example, in the area of the Lesser Khingan Mountains in Northeast China, frost falls in mid-September, while in the area of the Greater Khingan Mountains, frost falls in early September. With such a climate, sowing at this time makes it very difficult to harvest mature corn, because the corn cannot complete its growth period.

However, areas south of the Lesser Khingan Mountains can be considered, since the growth period can still barely satisfy the maturity and development of corn.

From the above analysis, it is not hard to see that at present, whether to sow corn in Northeast China depends on the local climate conditions. In addition, one point must be emphasized: at this time, sowing corn is already really quite late and not very suitable, but if you really still insist on planting corn, Science Agriculture suggests choosing the locally promoted corn varieties with a shorter growth period, and not choosing corn with too long a growth period, because the longer it is, the harder it is to mature.

In addition, Science Agriculture also suggests that other corn varieties can be appropriately considered. At this time, it is really not very suitable to plant corn, and there are also many crops that can be chosen for planting, such as Chinese cabbage.
