Abstract: In order to improve the yield and quality of sweet cherry, the effects of honeybee activity enhancer on honeybee activity,fruit setting rate,yield and commodity rate of sweet cherry were studied with sweet cherry variety Meizao as the experimental material.The results showed that the number of flower-visiting Osmia muricata was increased obviously,and the number of flower-visiting Osmia muricata per unit time on fruit trees in the experimental area(hanging Baolirui) which were 15 meters away from the hive,was the highest with 4.22 heads/(plant·min),2.14 heads/(plant·min) more than the control(no Baolirui),and 1.77 heads/(plant·min)more than the control on the 6th day of observation.The fruit setting rate and yield of cherry were also significantly affected by Baolirui. The fruit setting rate in the test area 15 meters away from the hive increased by 10.77 percentage points,the yield per plant increased by 3.52 kg and equivalent yield increased by 2 640 kg/ha.There was no significant effect on the commercial rate of cherry fruit,but the fruit quality of treated area was slightly better than that of control area.To sum up,we can use honey bee activity enhancer to improve the yield and quality of cherry in the future production, and then promote the development of cherry industry.
