The winter pod cucumber was sown in October, harvested at the end of December and early January, and ended in late spring. The worst temperature during the production period is the lowest, which makes the technical difficulty, but the economic benefits are significant. First, Changchun Mickey, Xintai Mickey and Nongda 14 are selected for the species. Second, the nursery uses a small arch shed to graft seedlings. 1, the production of seeding bed using a frame or flat. The bed is about 1 meter high. The bed size is 60,4010 cm long, wide and deep. It is located in front of the column in the greenhouse. Pingling seedbed is located in the middle of the greenhouse, which is 1-1.2 meters wide and 10 cm in soil thickness. The length depends on the number of seedlings. 2, nutrient soil preparation by volume calculation, decomposition of horse dung 60%, 10% of the manure surface, 10% of the furnace ash surface, 20% of the soil is not melon, add a small amount of potassium dihydrogen phosphate, sifted and mixed. Add 10 grams per square metre of carbendazim or kombat powder to disinfect the soil. 3, planting sowing date is October 15-25. Black seed squash is generally used as root stock, suitable for deep winter cultivation of cucumber for scion, cucumber seeds and pumpkin seeds are sown on the seedbed, scion seedlings must be larger than the rootstock seedlings, therefore, cucumber seeds to be sowed early 3-5 days. (1) soaking seed germination sowing: two days before sowing, the cucumber seeds are soaked in warm water of 60 °C, stirring until the water temperature drops to 30 °C and then remove and let dry for 30 minutes to remove the seed coat outside the mucus, and then put into the water soak For 2-4 hours, remove the seeds and wrap the seeds in a damp cloth at 25-30°C for germination. When the seeds are usually exposed for 24 hours, they can be sown. When sowing, press 8-10 cm square on the seeding bed. In each square, sows 1 seed with good buds, which is sealed tightly with the sieved fine soil and piled high 1.5 cm. After the cucumber seedlings emerged, the budded pumpkin seeds were sowed. (2) Grafting: Using the grafting method, the first true leaf of the cucumber grows to 2 or 5 cents in the size of the coin. The first true leaf of the pumpkin is grafted for the appropriate period and is watered 1-2 days before the grafting. Easy to raise seedlings. Take out the cucumber seedlings, rinse the earth with water and place it in a shallow basin. The pumpkin seedlings were taken from the seedbed, and the true leaves and growth points were cut with a blade. Then 0.5-1.0 cm below the cotyledons, a dicing direction along the two cotyledons was cut down. The angle was 35-40°C, and the tongue-shaped wedge surface was 1 cm long. about. Take a cucumber seedling that is slightly larger than the seedling of the pumpkin, about 1 cm long on a wedge surface, and then insert the two tongue-shaped wedge surfaces into each other, so that the two cotyledons of the cucumber seedling are on the two dicots of the pumpkin and cross Distribute and retain the stems of the cucumbers. Use a grafting clip to clamp the two joints so that they are tightly integrated. After grafting, plant them into a 10-cm-diameter nutrient bowl. Immediately tighten the small arch shed to maintain a high temperature inside the shed. The product completely healed and cut the cucumber stem along the lower part of the joint of the grafting clip and removed the grafting clip.
