通过田间试验揭示了凹唇壁蜂(OsmiaexcavaAtik)作为红富士苹果传粉媒体,对提高坐果和改善品质的作用,同时研究了影响该昆虫有效传粉的若干因子。结果表明:凹唇壁蜂的有效活动范围在距蜂巢60m半径的区域内,在该范围内,距蜂巢不同距离的供试树的坐果率指标无明显差异,但处理株平均坐果率都极显著地高于超过该范围的对照树,坐果率比对照提高81%～111%。弱树自然坐果率低,凹唇壁蜂传粉提高弱树坐果率效果更为明显。经凹唇壁蜂传粉,红富士苹果种子数、单果重和果形指数增加,但并未影响果实的着色和硬度。
Field experiments showed that OsmiaexcavaAtik, as a red-Fuji apple pollinator, could improve the fruit setting and improve the quality, and at the same time, studied several factors affecting the effective pollination of the insect. The results showed that the effective range of the bees was equal to 60m radius from the beehive. Within this range, there was no significant difference in the fruit setting rate of the test trees at different distances from the beehive. However, the average fruit set rate of the treated plants was extremely significant Higher than the control trees over this range, fruit set rate increased 81% ~ 111% compared with the control. Weak natural fruit setting rate is low, concave lip wall bee pollen to improve the effect of weak trees fruit set effect is more obvious. After bee pollinated, the number of Fuji apple seeds, fruit weight and fruit shape index increased, but did not affect the fruit coloring and hardness.
