How to manage the temperature in Cucumber planting

The planting area of cucumber in our country is very large. When planting cucumber, we should do a good job of management to ensure the growth of cucumber. We need to pay attention to all aspects, especially the temperature control of planting cucumbers in winter shed. Temperature is very important to the growth of cucumber, so we must pay attention to the management of temperature. So how to manage the temperature of cucumber planting? The following editor will give you a brief introduction, let's have a look!

1. Temperature requirement

The temperature requirements of cucumber are different in each growth period. Cucumbers like to grow in a warm environment, but to ensure a certain temperature difference. During the growth period of cucumber, the temperature should be controlled in the range of 15-30 degrees. If it is less than two degrees, then the cucumber will freeze to death. If we want cucumbers to adapt well to the low temperature environment, then we have to refine the seedlings. The cucumber after refining seedlings can withstand the lowest temperature of about 3 degrees, and can also withstand the temperature of zero in a short time.

2. Pre-planting temperature

The temperature of the seedlings should be controlled at about 26-28 degrees before emergence, and the temperature difference between day and night should be kept at about 10 degrees. Then we should also pay attention to control the soil temperature, the soil temperature should also be about 20 degrees. After the seedlings are unearthed, until the first true leaf grows, the temperature is 25 degrees during the day and about 16 degrees at night. During this period, if the temperature is not controlled properly, it will have a great impact on the growth of cucumber seedlings. If it is light, it will affect the growth of new leaves, and if it is heavy, it will cause the seedlings to die.

3. Temperature after grafting

If grafting is used, then we should pay attention to control the temperature before and after grafting. The temperature before grafting should be controlled before planting. After grafting, the seedbed temperature in the first three days should be controlled at about 26 degrees, and the temperature at night should be 19 degrees. After three days, the temperature should be reduced by about 3 degrees, and the lowest temperature should not be lower than 12 degrees, if it is lower than 12 degrees. After entering the slow seedling stage after planting, the temperature was controlled at about 26 degrees and 14 degrees at night. Then we need to do a good job of ventilation to ensure the normal growth of cucumbers.

4. Management of melon fruiting period

Then it is necessary to pay attention to controlling the temperature management of cucumber during the fruiting period. If it is planted in a winter shed, then the cucumber fruiting period is in winter, when the temperature is relatively low. In particular, we should pay attention to controlling the temperature. The temperature from 8 o'clock to 13:00 should be controlled at about 27 degrees. If it exceeds 28 degrees, then it should be properly ventilated. Before 5 o'clock in the afternoon, the temperature should be appropriately reduced by about 5 degrees. When it is below 20 degrees, close the vents in time. After entering the following spring, the temperature begins to pick up, at this time, it is necessary to do a good job of ventilation to ensure the temperature in the shed.

The above is a brief introduction to the management of temperature in cucumber planting. The temperature management of cucumber planting is very important, we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope I can help you.
