Cucumber breeding technology

Cucumber seedlings have mastered “four highs and four lows”, enabling fast and neat seedlings, robust seedling growth, strong stress resistance, and low melon parts, which mature 7-10 days in advance and increase production by 20%-30%. The main points of the technical procedure are as follows:

High temperature soaking, cryogenic storage species. Select the seeds as usual to remove the pods. The selected seeds are soaked in water at 55°C for 10-15 minutes. When the water temperature drops to room temperature, remove them and place them in a cloth bag. Store in a refrigerator at 5°C overnight and remove them with cold water on the next day. After draining, spare.

High-temperature germination, low-temperature refining buds. The spared seeds were germinated at a high temperature of 30°C to 40°C, and budding occurred in about 24 hours. 2 hours after budding, the temperature dropped to 20°C and the budding started for about 24 hours.

High temperature seedlings, low temperature seedlings. Seedlings are an important measure to gain strong seedlings and prevent leggy. Keep the temperature at about 40 °C before sowing, and pour boiling water on the clay. When the soil temperature reaches 40 °C, soak the seeds and sow the buds. The experiment showed that under the condition of high temperature at 40°C and soil temperature of 30°C, the seedlings can be topped with soil for 24 to 36 hours. After the top soil of the seedlings, the temperature dropped to about 20°C, and the seedlings were kept for 2 days.

High-temperature seedlings, low-temperature hardening seedlings. After the seedlings are transplanted, the room temperature is maintained at 30-35°C and the soil temperature is maintained at 30°C, which can shorten the period of seedlings. After easing the seedlings, keep 25°C during the day and 13-15°C during the night to promote seedling growth. 10-15 days before planting, the seedlings were cultivated at low temperature. The temperature dropped to 20°C during the day and 8°C-9°C during the night to enhance the adaptability and stress resistance of the seedlings.
