The Latest Temperature Management Methods for Cucumber Cultivation

Cucumbers are grown on a very large area in our country. When cultivating cucumbers, we need to do a good job with management to ensure the cucumbers' growth. We need to pay close attention to every aspect, especially temperature control when growing cucumbers in winter greenhouses. Temperature is crucial to cucumber growth, so be sure to manage temperature well. So how should temperature be managed when cultivating cucumbers? Below, the editor will give everyone a brief introduction. Let's take a look together!

1. Temperature requirements

Cucumbers have different temperature requirements at each growth stage. Cucumbers like to grow in a warm environment, but a certain temperature difference must also be ensured. During the cucumber growth period, the temperature should be controlled within the range of 15-30 degrees. If it is below two degrees, the cucumbers will freeze to death. If we want cucumbers to adapt well to a low-temperature environment, then we also need to harden the seedlings. After hardening, cucumbers can withstand a minimum temperature of around 3 degrees, and can also withstand a temperature of zero degrees for a short time.

2. Temperature before planting

Before the seedlings emerge, the temperature should be controlled at around 26-28 degrees, and the day-night temperature difference should be maintained at around 10 degrees. Then we also need to pay attention to controlling the soil temperature well; the soil temperature should also be around 20 degrees. After the seedlings emerge, until the first true leaf grows out, the daytime temperature should be 25 degrees, and the nighttime temperature should be around 16 degrees. During this period, if the temperature is not controlled properly, it will have a very large impact on the growth of cucumber seedlings. In mild cases, it affects new leaf growth; in severe cases, it can cause the seedlings to wilt and die.

3. Temperature after grafting

If grafting is used for planting, then we need to pay attention to controlling the temperature well both before and after grafting. The temperature before grafting should become the temperature control used before planting. After grafting, the seedbed temperature for the first three days should be controlled at around 26 degrees, with the nighttime temperature at 19 degrees. After three days, the temperature should be appropriately lowered by about 3 degrees, and the lowest temperature must not be below 12 degrees, if it is below 12 degrees. After planting, once it enters the seedling recovery period, the temperature should be controlled at around 26 degrees, with the nighttime temperature at around 14 degrees. Then ventilation work should also be done well to ensure normal cucumber growth.

4. Management during the fruiting period

Then we need to pay attention to managing the temperature well during the cucumber fruiting period. If growing in a winter greenhouse, then the cucumber fruiting period is in winter, when the temperature is relatively low. Special attention should be paid to controlling the temperature well. The temperature from 8 o'clock to 13 o'clock should be controlled at around 27 degrees. If it exceeds 28 degrees, appropriate ventilation should be provided. From the afternoon until before 5 o'clock, the temperature should be appropriately lowered by about 5 degrees. When it is below 20 degrees, the vents should be closed in time. After entering the spring of the following year, the temperature begins to rise, and at this time ventilation work should be done well to ensure the temperature inside the greenhouse.

The above is a brief introduction to how temperature should be managed in cucumber cultivation. Temperature management in cucumber cultivation is very important, and everyone must pay close attention to it. That is all for today's introduction.
