What factors affect corn planting time? Latest interpretation
Corn is a grain crop with a relatively large planting area in our country. There are also quite a lot of people who grow it, and when growing corn, if you want to increase yield, then the planting time of corn is very crucial, but corn planting time is affected by many factors. So what exactly are the factors that affect corn planting time? Today the editor will briefly introduce a few points for everyone. Let us take a look below!
1. Temperature
Temperature has a very large impact on corn planting time. If the temperature is too low, after sowing, the seeds will find it very difficult to germinate and are highly prone to cold damage. Moreover, in an environment with autumn frost, the ears cannot grow normally, causing yield and quality to be affected. Under otherwise normal conditions, the germination and emergence time of corn seeds is directly affected by the ambient temperature. The higher the temperature, the faster the seeds will germinate and emerge. Therefore, appropriately delaying the sowing time is beneficial for improving the emergence rate, and sowing should be carried out when the temperature at a depth of 5 cm in the tillage layer is stable at 10 degrees.
2. Moisture
After corn seeds are sown, if they are to germinate and grow normally, then moisture is certainly indispensable. Therefore, after sowing, we should pay attention to maintaining a certain amount of moisture to improve the germination and emergence rate of the seeds. And the sowing period should be appropriately adjusted according to the weather in the region. For example, in regions such as Northeast China, spring is relatively dry, which will affect the sowing period of corn. And in regions such as Hunan, when growing spring corn, if the sowing time is inappropriate, then after the seeds emerge they are very likely to suffer from spring drought, causing corn yield to decline.
3. Light
Light is likewise a key factor affecting corn planting time. During 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 region and the planted variety. For example, the growing season in northern China is relatively short, so if a southern variety is planted in the north, then it should be sown appropriately early. On the contrary, if a northern variety is planted in the south, then it can be done in spring, summer, and other seasons. A sufficient light environment should be provided according to the characteristics of the variety to ensure normal growth after the seeds are sown.
4. Others
Variety is a reason we have mentioned several times above. When planting, if it is a late-maturing variety, then the possibility of increasing yield is relatively greater, and it can be sown in spring. And if the growing season is insufficient, then it must be sown early, otherwise it cannot mature in time, affecting planting benefits. Then there are also altitude, soil, and so on. The higher the altitude, the longer the growth period of corn will be, so the sowing period should be adjusted in time. When planting in saline-alkali land, because the terrain is relatively low-lying and prone to water accumulation, it should be sown appropriately late.
The above is a brief introduction to the factors affecting corn planting time. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
