北方冬季在日光温室中应用壁蜂为桃树授粉,壁蜂破茧出巢始期和高峰期比露地推迟,整个破茧出巢期延长。保护地桃利用壁蜂授粉放蜂时间应在桃树开花前7～10d。日光温室内温度达到14.5℃成蜂开始出巢采粉和营巢,22～25℃活动频繁。供试5个保护地桃树品种利用壁蜂授粉比自花授粉坐果率提高18.8%～26.1%,接近人工授粉的坐果率。
The northern winter in the greenhouse greenhouse wall peach pollination for the peach, wall bee cocoon out of the initial and peak period than the open deferred, the entire cocoon out of the nest to extend. Peach conservation peach pollination using wall bee time should be flowering in the peach 7 ~ 10d. Sunlight greenhouse temperature reached 14.5 ℃ into the nests began bee picking and nesting, 22 ~ 25 ℃ frequent activities. The peach cultivars in five protected areas increased by 18.8% ~ 26.1% with wall bee pollination than self pollination, close to the rate of artificial pollination.
