Seedling management: greenhouse melon cultivation technology is sowing daytime temperature maintained at 28 ~ 32 ℃, night 18 ~ 20 ℃, not less than 13 ℃. After the seedlings alike, the daytime temperature is maintained at 20 ~ 26 ℃, night 10 ~ 13 ℃. After the leaves are flattened, they should be exposed to the wind for 22 ~ 30 ℃ during the day, 13 ~ 20 ℃ during the night and 2 ~ 3 true leaves at night. They should be kept at 18 ~ 20 ℃ during the day, 10 ~ 15 ℃ at night, Leaf stage planting. Reasonable fertilization: basal fertilizer every 667m ~ 2 into the rotten manure 3500 ~ 4000kg, superphosphate 60kg, ammonium bicarbonate 40kg, cake fat 100kg, the three
