Factors affecting the sowing time of Maize

Corn is a kind of food crop with large planting area in our country. There are also more growers, and if you want to increase the yield when planting corn. Then the sowing time of corn is very critical, but the sowing time of corn will be affected by many factors. So what are the specific factors that affect the sowing time of corn? Today, the editor will give you a brief introduction to a few points. Let's take a look at it.

1. Temperature

Temperature has a great influence on the sowing time of corn. If the temperature is too low, after sowing, the seeds are very difficult to germinate and are very easy to freeze. Moreover, in the environment of autumn frost, the ear can not grow normally, which affects the yield and quality. Under other normal conditions, the germination time of maize seeds will be directly affected by the ambient temperature. The higher the temperature, the faster the germination and emergence of seeds. Therefore, the appropriate postponement of sowing time is beneficial to improve the seedling emergence rate, and sowing should be carried out when the temperature of 5 cm in the plough layer is stable at 10 degrees.

2. Moisture

If corn seeds want to germinate and grow normally after sowing, then water is certainly indispensable. Therefore, after sowing, we should pay attention to maintain a certain amount of moisture and improve the germination rate of seeds. And the sowing time should be adjusted appropriately according to the weather of the region, for example, in the northeast and other areas, the drought in spring will affect the sowing period of corn. When planting spring corn in Hunan and other areas, if the sowing time is inappropriate, then the seeds will be easily affected by spring drought after emergence, resulting in a decline in corn yield.

3. Lighting

Light is also a key factor affecting the sowing time of corn. In the whole growth period of corn, the duration of light will have a direct impact on the growth period of corn. Therefore, it should be determined according to the planting area and varieties. For example, the growing season in northern China is relatively short, and if southern varieties are planted in the north, it should be sown early. On the contrary, if northern varieties are planted in the south, they can be planted in spring, summer and other seasons. According to the characteristics of the variety, it is necessary to provide sufficient light environment to ensure the normal growth of seeds after sowing.

4. Other

Variety is the reason why we have just mentioned many times above. When planting, if it is a late-maturing variety, then the possibility of increasing production is relatively large, but spring sowing. If the growing season is compensated, it must be sown early, otherwise it will not mature in time and affect the planting efficiency. Then there is altitude, soil and so on. When the altitude is higher, the growth period of corn will be longer, so the sowing date should be adjusted in time. When planting in saline-alkali land, because the topography is low-lying and easy to accumulate water, it should be sown late appropriately.

The above is a brief introduction to the factors that affect the sowing time of corn. That's all for today's introduction. This article is for reference only. I hope it can help you all.
