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 m^2)^-1,处理Ⅱ:200头·(667 m^2)^-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 m^2的网室放置200头熊蜂,距蜂箱9 m处区域种子质量最好。
This paper studied the effect of bumblebee numbers and distance between hives on watermelon seed production in net room by treatmentⅠ:2250 bumblebees·hm^-2 and treatmentⅡ:3000 bumblebees·hm^-2.Results showed that all indicators of watermelon seed treated by treatmentⅡwere superior to those treated by treatmentⅠ,when the distances between hives were the same.Among treatmentⅡ,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 treatmentⅡ.There was no significant differences between the above 2 sites.The highest weight of single watermelon and the 1000 seed were found at the site 12 m away from the hives under treatmentⅡ,followed by the site 9 m away from the hives under treatmentⅡ,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 3000 bumblebees·hm^-2 in net room.
