Detailed Explanation of Temperature Management Techniques for Cucumber Cultivation
Cucumbers are grown on a very large area in China. When growing cucumbers, we need to do a good job of management to ensure the growth of the cucumbers. We need to pay close attention to every aspect, especially temperature control when growing cucumbers in winter greenhouses. Temperature is crucial to the growth of cucumbers, so we must pay attention to doing a good job of temperature management. So how should temperature be managed in cucumber cultivation? Below, the editor will give you 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 maintained. During the growth period of cucumbers, the temperature should be controlled within the range of 15-30°C. If it falls below 2°C, 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°C, and can also withstand a temperature of 0°C for a short time.
2. Temperature Before Planting
Before the seedlings emerge, the temperature should be controlled at around 26-28°C, and the day-night temperature difference should be maintained at around 10°C. Then we also need to pay attention to controlling the soil temperature well; the soil temperature should also be around 20°C. After the seedlings emerge, until the first true leaf grows out, the daytime temperature should be 25°C, and the nighttime temperature should be around 16°C. 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 the growth of new leaves; 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 be changed to the temperature control used before planting. After grafting, the seedbed temperature should be controlled at around 26°C for the first three days, with a nighttime temperature of 19°C. After three days, the temperature should be appropriately lowered by about 3°C, and the temperature should not be lower than 12°C at minimum. If it falls below 12°C, [there will be problems]. After planting, once the seedling revival stage begins, the temperature should be controlled at around 26°C, with a nighttime temperature of around 14°C. Then ventilation work should also be done well to ensure normal growth of the cucumbers.
4. Management During the Fruiting Stage
Next, pay attention to managing the temperature well during the cucumber fruiting stage. If growing in a winter greenhouse, then the cucumber fruiting stage 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°C. If it exceeds 28°C, appropriate ventilation should be carried out. From the afternoon until before 5 o'clock, the temperature should be appropriately lowered by about 5°C. When it is below 20°C, the ventilation openings 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 to manage temperature 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. This article is for reference only, and we hope it can help everyone!
