1, high temperature soaking, cryogenic storage species.
1 Soak the cucumber seeds in warm water of 13°C for 4 hours, remove them and put them in cloth bags, and store them in a household refrigerator at 5°C for 12 hours.
2 Then take out the shower with cold water, control the water and then put the bag into the basin for use.
2, high temperature germination, low temperature refining.
1 The alternate seeds were germinated at a high temperature of 30-50°C and sprouted for 24 hours.
2 After 2 hours of bud whitening (arch mouth), cool down to 20 °C for 20 hours.
3, high temperature seedlings, low temperature seedlings.
1 Keep the temperature of the greenhouse at 40°C before sowing, and pour water on the seedbed soil. When the soil temperature reaches 40°C, sow the seeds that have germinated.
2 In the greenhouse temperature of 40 °C, soil temperature of 30 °C under high temperature conditions for 24 to 36 hours, the seed can be fully arched soil emergence.
After the 3 seedlings were unearthed, the temperature was lowered to 20°C and the seedlings were allowed to stand for 2 days.
4, low-temperature seedlings, low temperature hardening seedlings.
1 After the seedlings were transplanted, the greenhouse temperature was maintained at 30-35°C, and the soil temperature was maintained at 30°C.
2 After easing the seedlings, the greenhouse temperature shall be maintained at 25°C during the day and 13°C to 15°C during the night.
3 10-15 days before planting, the temperature dropped to 17-20°C during the day and lowered to 8-9°C during the night for low-temperature hardening.
Cucumber "four high and four low" seedling raising technology
Greenhouse cucumbers use “four highs and four lows†seedling raising techniques to make cucumber seedlings robust, strong resistance to plants, low guarana, and cucurbits. They are raised for 7 to 10 days in the morning and increase production by 30%.
