When will spring corn be sown? What are the dangers of sowing too early?

In a twinkling of an eye, it is spring again, and many areas have begun to carry out crop sowing and production activities. Spring is a critical season for farmers, and the cost of growing crops may be on top of it all year round, so we still pray for a smooth weather. As our common crops, wheat and corn are on the tip of the tongue. Most farmers plant corn in spring, so do you know when spring corn will be sown? Will it do any harm if you sow too early? Let's have a look together!

When will spring corn be sown?

Spring corn sowing has a different time in each region, because the temperature difference is also different in each of the larger regions of China. The difference in temperature between the north and the south leads to the lack of a unified definite value. in general, most of the seeds are sowed between late April and early May, and if the local temperature is suitable, they can be sowed in advance to mid-April. At the same time, according to different varieties, the sowing time will be adjusted accordingly, for example, early-maturing varieties can be sowed late, while late-maturing varieties can be sowed early.

Second, what are the hazards of sowing spring corn too early?

1. The emergence rate is low.

After spring storage corn is generally sown, proper temperature is needed for normal germination and emergence, so it is not recommended to sow seeds prematurely. It is better to stabilize the whole temperature environment at more than 10 degrees. If you insist on sowing prematurely for yield, the temperature is too low at that time, which may lead to frustration in the germination of seeds in the soil, affecting the germination rate, and then the emergence rate will also be reduced. According to the specific conditions of the emergence rate, the replanting, transplanting, and seed destruction.

2. easy to rot and lack of seedlings.

Generally sowing spring corn ahead of time, the moisture in the soil is not completely dry, and the water density from winter still takes time to be air-dried, so it is not conducive to the germination of spring corn. Especially in the three eastern provinces, some areas are still snowing and sowing prematurely, and there may still be snow in the field. On the other hand, after the snow melts, it is not yet dry and the field humidity is too high, both of which are not conducive to corn sowing. If forced sowing, the phenomenon of rotten seeds and lack of seedlings will greatly increase.

3. It is easy to cause weak seedlings.

Weak seedlings are generally caused by sowing time or fertilizer and water irrigation in the later stage. When sowing early spring corn, the tolerance to temperature is not strong enough, and weak seedlings occur from time to time in low temperature environment. Moreover, if you sow too early, the demand for nutrients consumed by spring corn will increase. If factors such as water and fertilizer are in short supply, your own resistance will be weakened, and the problem is often that no seedlings will emerge, or weak seedlings will appear collectively, and it will be very difficult to grow later, which is tantamount to losing seeds and wasting manpower.
