High temperature soaking, cryogenic storage species. Cucumber seeds were first immersed in warm water at 13°C for 4 hours, then removed and put into cloth bags, and stored overnight in a refrigerator at 5°C. On the second day, remove and wash with cold water. After the water is air-dried, put the bag into the basin for use.
High temperature germination, low temperature refining. The seeds in the pot were germinated at a high temperature of 30°C to 50°C, and all sprouted in 24 hours. Buds arched mouth to cool to 2O<0>C after 2 hours and allowed to bud for 20 hours.
High temperature seedling, low temperature seedlings. Maintain 40°C at room temperature before sowing, and pour boiling water on the clay. When the soil temperature reaches 40°C, sow the seeds that have germinated. After 24-36 hours at a high temperature of 40[deg.] C. and a soil temperature of 30[deg.] C., the seedlings can all be soiled. After the seedlings buried the soil, the room temperature was lowered to 20°C and the seedlings were allowed to stand for 2 days. High-temperature seedlings, low-temperature hardening seedlings. After transplanting the seedlings, the room temperature was maintained at 30°C-35°C and the soil temperature was maintained at 30°C. After easing the seedlings, keep it at 25°C during the day and 13°C-15°C at night. 10-15 days before planting, the seedlings were cultivated at low temperature. The temperature dropped to 17°C-20°C during the day and 8°C-9°C at night.
