熊蜂和蜜蜂为塑料大棚西瓜授粉对比试验

熊蜂和蜜蜂为塑料大棚西瓜授粉试验得出,熊蜂授粉比蜜蜂授粉的平均单瓜重较重,差异不显著(P>0.05);单位面积产量较多,差异不显著(P>0.05);瓜型更周正,差异显著(P<0.05);VC含量较高,增加0.14%;总糖较高,增加2.22%;糖酸比较高,增加2.23%;可溶性固形物较低,降低2.04%;硝酸盐相同;说明熊蜂授粉比蜜蜂授粉产量略高,瓜较重,外观较好,VC含量较高,糖含量较高,口感相差不大,均可达到有机食品标准。证实了熊蜂授粉技术可以代替蜜蜂授粉技术。

Comparison of bumble bees (B.lucorum) and honey bees (A.mellifera) as pollinators for Watermelon grown in plastic house culture

The comparative experiment of bumble bees and honey bees as pollinators for strawberry grown in plastic house culture,the result showed that average fruit weight of watermelons by bumblebees pollination were higher than those by honeybee pollination, but there were no significant differents(P>0.05). yields of watermelons in unit area were higher,there were no significantly differents(P>0.05). The type of watermelons were better, there were significantly differents(P<0.05). Vitamin c were higher, and increasing 0.14%. Percentage sugars were higher, increasing 2.22%. the rate of sugar and acidity were higher, and increasing 2.23%. lower, Total Soluble Solid(TSS ) were lower,decreasing 2.04%. Nitrates were same. The experiment results prove that bumblebees are more suitable to pollinate for watermelons grown in greenhouses, bumblebees pollination may substitute for honey bees pollination.
