(1) Temperature and light adjustment After planting, keep 28 to 32 °C during the day and 15 to 20 °C during the night to promote slow seedling. After 5 to 7 days of slow seedling, the temperature is appropriately lowered, and 23 to 25 ° C during the day and 12 to 15 ° C during the night. After flowering and sitting on the melon, keep 25 to 30 ° C during the day and 15 ° C at night. In January-February, the sunshine time is insufficient, and the grasshoppers should be exposed early and covered, and the lighting time should be extended as much as possible. In the early stage of planting, the outside temperature is very low, and cover measures should be taken to maintain the proper temperature in the facility, so as not to be frozen or chilled. In the case of even cloudy days, it is necessary to expose the grass in the short term at noon, and do not cause yellowing of the leaves due to long-term lack of light. Entering March to April, the outside temperature is getting higher and higher, and the daytime should be ventilated and cooled in time. Do not allow the temperature to exceed 35 °C. When the nighttime temperature is stable above 15 °C, it should be ventilated at night, and gradually remove the grasshoppers, remove the plastic film, and transfer to open field cultivation. (2) Water and fertilizer management is planted after planting. Because the outside temperature is low, it is not watered until the vines are pumped. It can cultivate loose soil, increase ground temperature and promote root growth. The watering period begins with watering and topdressing, applying 750 kg of diammonium phosphate per hectare. When the first melon is sitting and growing to 10-15 cm long, always water it to keep the soil moist. When the second melon appeared, 750 kg of diammonium phosphate and 300 kg of potassium sulfate were applied per hectare. (3) Scaffolding, tying vines, melons, or climbing to grow. In order to increase the yield and enhance the resistance in the protected area, the scaffolding method is generally used. In the solar greenhouse, plastic flat wire is generally used as a support, and one plant per plant can also be made into a fence by bamboo poles. When the melon is 30 cm, tie the vine. After each 30 cm in length, tie the vine once. The stems and leaves are evenly distributed on the shelf. In the early stage of growth, the main vines were the main result, and all the side vines were removed. The main fruit is the main fruit, after the first vine is seated, the two side vines are kept, and each side is topped with a melon. If you take the old melon, you can hit all the side vines, so that the main vines are 2 to 3 melons. (4) In the early pollination cultivation of artificial pollination, the flowering period is very early, and there is no insect pollination season in early spring. In order to increase the rate of sitting, artificial pollination should be carried out. Every day from 6 to 10 in the morning, pick up the male flower that was opened that day, remove the corolla, and smear a few times on the stigma of the female flower.
