From 2010 to 2010, special attention should be paid to temperature control when managing greenhouse cucumbers. Generally, the temperature in the greenhouse is about 20 degrees under low light and about 25 degrees under strong light. The temperature at night is about 10-18 degrees. Pay attention to the temperature difference between day and night. The temperature difference should be slightly larger, preferably greater than 8 degrees.

1. Temperature control

Cucumbers grown in greenhouses grow relatively slowly in winter, especially in low-light environments, and consume less water. Fertilizing and watering twice before the Spring Festival is enough. . Once a month or so and once during the Spring Festival. Proper watering after fertilizing will help dilute the fertilizer and promote better and faster absorption by the cucumbers.

2. Appropriate amount of fertilizer and water

During the winter management period, it is necessary to sort out the fruits again. Timely roll paper, hang vines, and emasculate flowers. Removing deformed, curved, and thin young fruits can save a lot of nutrients and promote better growth of healthy cucumbers. From 2010 to 2010, the outside temperature was relatively low, photosynthesis could not proceed well, and the cucumbers did not last long. Tender melons should be picked promptly. However, if the cucumbers are growing well, they will be ready to pick in a few days.
