Changchun City Kuancheng village, there are seven years of experience planting cucumber king Meng Qinghong management know-how is: 1, temperature, moisture and ventilation early planting to improve shed temperature. Shed temperature below 42 ℃ without ventilation, with no dripping membrane maximum temperature control at 39 ℃, soil moisture sufficient, no roasted seedlings without ventilation. Huanmiao seedling growth slow greenhouse shed temperature control below 38 ℃, rapid growth temperature below 35 ℃. Sheng melon period shed temperature below 35 ℃.
