摘要
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 peach in sunshine greenhouse has been pollinated with mason bees in winter in Northern China.The beginning and the climax time of mason bees which bursting open the cocoon and come out of the nest will be put off when compared with that in the open field,the whole period will be extended.The pollination method for peach by using mason bees in protective ground should not be the same as in the open field.The releasing time of mason bees should be seven to ten days before blooming.When the temperature reaches 14.5℃ in sunshine greenhouse,bees begin to come out from the nest to collect pollen and build nest,and their activities is most active when the temperature reaches 22~25℃.When the mason bees were used,the fruit setting rate raised up for 18.8%~26.1% than that of self-pollinated,it approaches the fruit setting rate in artificial polli- nation.In protective ground,peach pollination with mason bees can take the place of the higher cost artificial pollination.
