Six-axis rotorcraft UAV(SH-X6-10 B) was used to conduct the assisted pollination experiment of Chinese fir seed orchard, and then seed setting rate and operating efficiency of Chinese fir were compared with different flying heights,flying speeds,pollination medias,pollen to medium ratio,and pollination methods.The results showed that a flight height at 6~8 m of uav from the treetop is the best height for fruit setting(65.0%) in Chinese fir.Chinese fir which pollinated with flying speed of 2~3 m·s~(-1) presents the highest fruit setting rate,reaching 67.2%.The seed setting rate of talc was the most suitable pollination medium for Chinese fir in a level of 66.0%.The ratio of pollen to talc at 1∶50 was the best combinations in fruit setting rate of Chinese fir,reaching 66.1%;Fruit setting rate by UAV increased by 46.0% and 117.5%,respectively, compared with that of artificial pollination and natural pollination.The efficiency by UAV is 33 times than that by manual pollination.
