摘要 通过在西瓜制种网室放置不同数量的熊蜂〔处理Ⅰ：150头 ·（ 667 m2）-1，处理Ⅱ：200头 ·（ 667 m2）-1〕，研究熊
蜂数量和蜂箱距离对网室西瓜制种的影响。结果表明：与蜂箱的距离相同时，处理Ⅱ的西瓜种子各项指标均优于处理Ⅰ，其
中处理Ⅱ距蜂箱6 m 处区域单瓜种子粒数最多，显著高于人工授粉的对照，单瓜种子质量也最高，其次是处理Ⅱ距蜂箱9 m
处区域，2 个区域间无显著差异；处理Ⅱ距蜂箱12 m 处区域单瓜质量和种子千粒重最高，其次是处理Ⅱ距蜂箱9 m 处区域，
均与对照无显著差异。综上，每667 m2 的网室放置200 头熊蜂，距蜂箱9 m 处区域种子质量最好。
Abstract：This paper studied the effect of bumblebee numbers and distance between hives on watermelon
seed production in net room by treatment Ⅰ：2 250 bumblebees · hm-2 and treatment Ⅱ：3 000 bumblebees ·
hm-2．Results showed that all indicators of watermelon seed treated by treatment Ⅱ were superior to those
treated by treatment Ⅰ，when the distances between hives were the same．Among treatment Ⅱ，the seed number
of single watermelon at the site 6 m away from the hives was the largest，significantly higher than that of the
contrast．Besides，the seed weight of single watermelon in this area was also the hightest，followed by the site
9 m away from the hives under treatment Ⅱ．There was no significant differences between the above 2 sites．
The highest weight of single watermelon and the 1 000 seed were found at the site 12 m away from the hives
under treatment Ⅱ，followed by the site 9 m away from the hives under treatment Ⅱ，there was no significant
differences with that of the contrast．In conclusion，seed quality is the best at site 9 m away from the hives and
with 3 000 bumblebees · hm-2 in net room．
