渭北高原区苹果壁蜂授粉技术的规范研究

Normative Research of Pollination by Osmia Cornifrons on Apple in the Weibei-loess Plateau

为了规范渭北高原苹果产区应用壁蜂授粉技术。通过田间试验研究了壁蜂不同释放方法、巢箱高度、巢材管对壁蜂出茧速度、出茧率、营巢管率等的影响。结果表明:剥茧放蜂法出茧速度最快、出茧率和营巢管率最高。巢箱距地面20 cm左右营巢管率最高。纸巢管和芦苇巢管的营巢管率显著高于塑料巢管。

In order to standard the pollination technology by Osmia cornifrons of orchardist which lived in the Weibei-loess plateau,the effect of Osmia out of cocoon by the different styles,the place of nest boxes and the tube of nest on leaving the cocoon was studied by comparison method.The results showed that stripping the cocoon method was the best way,which had the highest ratio of breaking through and nidification.The height of nest boxes should be 20 cm above ground.The nest ratio of bulrush and paper were higher than that of plastic tube.
