The new technology of "four highs and four lows" cucumber breeding

Compared with the conventional cucumber seedling raising method, the "four highs and four lows" seedling raising technique can bring about fast and neat seedling growth, strong seedling growth, strong stress resistance, and low part of the melon. It matures 7 days to 10 days in advance and increases production by 20% to 30. %. The main points of its technical procedure are as follows: High-temperature soaking, cryogenic storage. Select the seeds as usual to remove the pods. The selected seeds were soaked in warm water of 13°C for 4 hours, then they were put into a cloth bag and stored in a refrigerator at 5°C overnight. The next day, they were rinsed with cold water and drained for use. High temperature germination, low temperature training buds. The alternate seeds were germinated at a high temperature of 30°C to 40°C, and all sprouted in about 24 hours. 2 hours after budding, the temperature dropped to about 20°C and the budding began. The time was about 20 hours. High temperature seedlings, low temperature seedlings. Seedlings are an important measure to gain strong seedlings and prevent leggy. Keep about 40°C at room temperature before sowing, and pour boiling water on the clay. When the soil temperature reaches 40°C, warm the seeds and sow the seeds. The experiment showed that under the high temperature conditions of 40° C. and 30° C. soil temperature, the seedlings can be topped with soil for 24 hours 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 kept at 30°C-35°C and the soil temperature is kept at 30°C, which can shorten the period of seedlings. After easing the seedlings, keep 25°C during the day and 13°C～15°C during the night to promote seedling growth. For the first 10 days to 15 days, the seedlings were cultivated at low temperature. The temperature dropped to 20°C during the day and 8°C to 9°C during the night to enhance the adaptability and resilience of the seedlings.
