When cucumbers are nursed, the use of variable temperature treatment is an important measure for cultivating strong seedlings and realizing high yield and stable production of cucumbers. The cucumber temperature change seedling techniques are briefly summarized as follows:

1. Seed temperature change treatment. Soaking in warm water, low-temperature seed storage, high temperature germination, low-temperature refining buds. The seeds were germinated at a temperature of 25°C to 30°C. After the seeds had sprouted for 2 hours, the seeds were allowed to germinate for 2 hours when the temperature was lowered to 20°C.

2. Seedbed temperature management. From seeding to pre-emergence, the seedlings must be raised at high temperature, kept at 25°C-28°C during the day, 15°C-17°C at night, and 20°C-25°C at the ground temperature; after emergence, the first true leaves must be grown to prevent leggy, Keep at about 20°C during the day, 10°C-12°C at night, and 16°C-20°C at the ground temperature; 7 days before the first true leaf appears until 7 days before planting, the daytime temperature is kept at 20°C-25°C and nighttime at 13°C-15°C. , Ground temperature 18°C-20°C; 7 days before planting, should be gradually cooled, controlled at 25°C during the day, no more than 28°C, reduced to 8°C-10°C at night, and ground temperature dropped to 12°C, so that the temperature is close to the temperature after planting . The seedlings cultivated in this way are neither legible nor aging; after planting, the survival rate is high.

Transplanting seedlings temperature change treatment. High-temperature seedlings, low-temperature hardening seedlings. After the seedlings were transplanted, the daytime temperature was controlled at 25°C-32°C and 15°C at night. After the seedlings were soaked, they were maintained at 25°C during the day and 13°C-15°C during the night.
