How many days does it usually take for corn to sprout after sowing?

Corn is an annual herbaceous plant of the genus Zea of ​​the Poaceae family. It is now widely cultivated in many regions of my country. Its growth cycle is divided into seedling stage, jointing stage, tasting stage, flowering stage, filling stage and maturity stage. So how many days does it usually take for corn to sprout after sowing?

How many days does it usually take for corn to sprout after sowing?

It usually takes about 5-10 days for corn to germinate after sowing. Specifically: Under suitable temperature conditions, corn seeds will generally germinate about 5-7 days after sowing.

The sowing time in spring is slightly longer, and it usually takes about 7-10 days for the seedlings to germinate. Taking summer corn as an example, under normal circumstances, it takes 8-13 days for spring corn to sprout from sowing to germination, and 5-6 days for summer corn.

After corn is sown, it will germinate in about 5 to 10 days if the climate and soil moisture are suitable. It varies depending on soil moisture conditions and temperature, and generally seedlings will emerge in 7-10 days.

What is the reason why corn does not germinate?

1. Soil pest problem

Some fields are seriously infested by soil pests. If preventive measures such as seed dressing are not taken before sowing, corn seeds may be destroyed by these pests. Once the seeds are damaged, their germination and emergence will be directly affected.

2. Improper use of seed dressing agent

In contrast to the problems caused by not using seed dressing agents, excessive use of seed dressing agents may also result in stunted growth of seedlings. For example, during the seed dressing process, if the dressing is uneven and some seeds are exposed to too much liquid medicine, the growth of these seeds may be inhibited, which will affect germination.

3. Effect of low temperature

In order to seize the opportunity to sow seeds, some farmers may ignore local temperature conditions. If the temperature is too low, especially when the temperature is below 10 degrees Celsius, the germination ability of the seeds may be seriously affected, resulting in failure to germinate normally.

4. Soil moisture is too high

When the soil moisture in the field is too high, that is, there is too much water, such as continuous rainfall after sowing and poor drainage, the normal respiration of the seeds will be affected, ultimately hindering their germination and emergence.

5. Improper use of herbicides

Some farmers choose to use pre-emergence closed herbicides to control weed growth after corn planting. However, if herbicides are used excessively or at the wrong time, they may cause phytotoxicity, thus affecting the normal emergence of corn.

6. Fertilizer damage

Some farmers apply fertilizers at the same time as sowing. If the operation is not done properly, the seeds and fertilizers will come into direct contact or be too close to each other, which may cause fertilizer damage and prevent the seeds from germinating successfully.

In general, the time it takes for corn to emerge after sowing is affected by many factors, including temperature, soil moisture, etc., and is generally around 5-10 days.
