摘　　要：为探索‘西农8号’在宁夏灌区的最佳整枝方式,采用双蔓整枝、三蔓整枝、四蔓整枝和放任生长不整枝4种处理方式,对西瓜早期产量和总产量进行了统计和分析。结果表明,双蔓整枝处理的早期产量最高,与三蔓整枝、四蔓整枝和放任生长处理有极显著差异。三蔓整枝处理的总产量最高,667 m2产量可以达到3 159.67 kg,与放任生长、双蔓整枝和四蔓整枝处理有极显著差异;放任生长的总产量极显著高于四蔓整枝和双蔓整枝;四蔓整枝和双蔓整枝的总产量之间差异不显著。在宁夏当地栽培条件下,三蔓整枝667 m2产量为3 159.67 kg,是宁夏灌区主栽品种‘西农8号’的最佳整枝方式。The objective of this experiment is to explore the best way of pruning of ＇ Xinong No. 8 ＇ watermelon variety in Ningxia irrigation area. The main variety of watermelon ＇Xinong No. 8＇ used as experimental material, four pruning methods （double vine pruning, three vine pruning, four vine pruning and no pruning） were adopted as four treatments. The earliest yield and total yield in the whole period of watermelon was the highest using double vine pruning and there was highly significant difference compared with other pruning methods. The total yield （3 159.67 kg per 667 m2） was the highest using three vine pruning, and was significantly different from other pruning methods. The total yield of control was superior to two vine and four vine pruning （P〈0.01, statistically highly significant）. There was no significant difference between four vine pruning and two vine pruning. Three vine pruning treatment was the best for watermelon cultivation of ＇Xinong No. 8＇ in Ningxia irrigation area.
