Thick-skinned melons enjoy a higher temperature than muskmelons, and the planting period is a little late. Generally, the gardens are opened later than muskmelons, and they are resistant to transportation. They are greatly affected by the warmth of the northern transportation in the warm area. It is one of the important precocious measures.

The early maturity of Elizabeth, Yellow River Honey, and Reticulated Muskmelon seedlings are selected. It is best to raise seedlings about 40 days before the appropriate planting period, preferably in a solar greenhouse. The nursery effect on the horse dung hotbed in the greenhouse is also very good. Before sowing, soak the seeds in warm water at 25 ℃ ~ 30 ℃ for 8 ~ 10 hours. After the seeds are out of water, dry the surface with floating water, wrap the cloth, and germinate at a temperature of about 30 ℃. When the buds grow about 1 cm, sow the seeds. A large centimeter bowl holds the bed soil. After pouring the bottom water, sow a germinated seed in each bowl, cover the bed soil 1.5 to 2 centimeters thick, place the nursery bowl in the solar greenhouse or the greenhouse of horse manure in the greenhouse, and cover it with mulch Nursery bowl, keep warm and moisturize. After sowing, maintain the soil temperature in the nursery bowl at 20 ℃ ~ 22 ℃. The temperature of the seedling bed is 28 ℃ ~ 30 ℃ during the sunny day and 18 ℃ above the night. The seedling emerges at a higher temperature to ensure the uniformity of the seedling and prevent the seedling stage cataplexy. Under this condition, seedlings emerge in about 3 days, and the mulch is removed when the buds are buried in the soil to prevent the buds from being burned around noon.

After emergence, the temperature will be reduced to 26 ℃ ~ 28 ℃ in the sunny day and 15 ℃ ~ 16 ℃ at night. After the two true leaves are exhibited, the night temperature can be reduced to 13 ℃ ~ 15 ℃. The seedling pot can't be drought, and it should be watered every 5-7 days. After watering, the piece of soil can lengthen the number of days between watering, thereby reducing the number of watering. Thick-skinned melons like strong light, to keep the shed film clean, without water drops, and to enhance the light intensity. When the seedlings have about 3 true leaves, in order to prevent the seedling leaves from shading each other, the distance between the stalks and the pots should be opened in time to improve the light situation inside the seedling group. If the color of the large leaves at the base fades out, it is the performance of nitrogen-deficient fertilizer. Leaf fertilizer should be sprayed. The seedlings can grow 4 ~ 5 true leaves about 40 days after sowing, reaching the suitable planting age. Because the large and middle sheds of thick-skinned melons are cooler than the solar greenhouses and horse dung hotbeds for seedlings, in order to adapt the seedlings to the lower temperatures in the large and medium sheds, the seedlings are trained 5 to 7 days before planting, that is, Try not to water, increase the amount of air during the day, gradually reduce the cover at night, gradually reduce the night temperature to 7 ℃ ~ 8 ℃, enhance the adaptability of the seedlings to low temperature, can be planted early for a few days, early seedlings and early maturity. When the soil temperature in the 10 cm deep layer in the large and medium sheds is stable at about 12 ℃, plant 4 to 5 true leaf seedlings in the large and medium sheds.
