In winter, the temperature is low, and greenhouse cucumbers are prone to "melon topping" problems. The specific symptoms are as follows: the growing point of the plant is clustered and no longer growing upwards; the length of the internodes near the growing point is shortened, and no new leaves can be formed; clusters of mixed female and male flowers are formed around the growing point; after the flowers bloom The melon strips are not elongated and have no commercial value. At the same time, the melon vines stop growing and the plants are low. Four methods should be adopted to prevent "melon topping": 1. Remove the young melon at the top of the cucumber to promote the growth of vines. 2. Insulation and brightness enhancement. Keep the shed temperature at 28℃～30℃ during the day and 15℃ at night. Improve the shed environmental conditions to promote the growth of cucumber from weak to strong as soon as possible. 3. Strengthen fertilizer and water management. Raise roots, promote vines, and improve cucumber growth. 4. Use medicines rationally and use hormone pesticides with caution to avoid phytotoxicity.
