The minimum temperature for seed germination is 16 ℃ ~ 18 ℃, and the optimal temperature is 30 ℃ ~ 35 ℃; the optimal temperature for seedling growth is 20 ℃ ~ 25 ℃ during the day. The growth stopped at 10 ℃, and cold damage occurred at 7.4 ℃. temperature Stem and leaf growth is suitable for day temperature 25 ℃ ~ 30 ℃, night temperature 16 ℃ ~ 18 ℃. Long-term growth is below 13 ℃ or above 40 ℃. The optimal temperature during flowering and fruiting period is 25 ℃, and the night temperature is 18 ℃ ~ 20 ℃. The optimum temperature for fruit development is 30 ℃ ~ 35 ℃ during the day and 15 ℃ ~ 18 ℃ at night. illumination Thick-skinned melons are light-loving crops, and normal growth requires more than 12 hours of light per day. When there are more than 12 hours of light per day, the plants form more female flowers. With 14-15 hours of light per day, the plants grow fast and side vines occur early. humidity Thick-skinned melons have a suitable relative humidity of 50% to 60% for growth and development. Long-term air humidity of more than 80% will make the plant grow poorly and be susceptible to diseases. Different growth stages have different requirements on air humidity, and have a strong adaptability before flowering and fruit setting. The air humidity is strict during the flowering and fruit setting period. Short-term high temperature and low humidity during the day, normal temperature at night, less impact on flowering and fruit setting. Day and night high temperature and low humidity are serious. The air humidity is too high, pollen is not easy to escape, affecting pollination. soil Thick-skinned melon grows well in loam or sandy soil with deep soil, rich organic matter and good permeability. Cultivated in sandy soil, it is easy to grow seedlings, grow fast, mature early, and have good quality, but the plants are prone to premature decay and the yield is low. The soil pH suitable for melon roots is pH 6.0 ~ 6.8. Soil overacid affects the absorption of calcium ions and other elements, and is conducive to the survival and occurrence of pathogens such as Fusarium wilt.
