1 The test ground conditions The experiment is located in the greenhouse of Qingshan County Fruit Research and Development Center for Grapes and Fruits. The soil has the medium soil fertility with sufficient sunshine. The sunshine duration is 2900 ~ 3100 hours and the annual rainfall is 17.6 ~ 25.3mm. The temperature difference between day and night is large, Frost-free period is long (192 ~ 224 days). This condition is very conducive to the growth of cotton, grape and sweet watermelon, through the determination of grape sugar content, up to 23 degrees above. Summer black grapes spacing of 2m × 4m, applied organic fertilizer 2500kg / 666.7m2, inorganic fertilizer
