整枝有调节西瓜植株生长势、提高叶片素质、促进坐果、增大果形等效应，但在一定程度上有减少雌花数目和结果数，降低产量等副作用；整枝应与适当密植结合起来以弥补其负面效应。在生产中，①早熟栽培可增加种植密度、减少蔓数，以增加果数，提高早期产量；②露地栽培则可减少种植株数，增加蔓数，以提高叶面积，增大果形，增加产量。③主蔓的去留与品种有关，生长势弱的品种主蔓应予保留，长势强的品种则宜摘除主蔓，利用侧蔓结果
Pruning can regulate watermelon plant growth potential, improve leaf quality, promote fruit set, increase fruit shape and other effects, but to some extent reduce the number of female flowers and the number of results, reduce production and other side effects; pruning should be combined with the appropriate close planting to make up Negative effect. In production, ① precocious cultivation can increase the planting density, reduce the number of the vine, in order to increase the number of fruit, improve the early yield; ② open-field cultivation can reduce the number of plants, increase the number of leaves to increase the leaf area, increase fruit shape, increase yield . ③ the main vine to go and stay with the variety, the weak growing species of the main vine should be retained, the growing strong varieties should be removed from the main vine, the use of lateral vine results
