Four mixed orchards that planted ‘American No.Eight’ apple(early-maturing),‘Gala ’apple(middle-maturing)，and ‘Red Fuji’apple(late-maturing)，and set four treatment（colored net，vane wheel，ultrasonic and biological insecticides) which was 2/3 hm2.Four bird scaring technologies were compared and the effect of driving bird was studied，to choose the best driving technologies.The results showed that the colored net were the best under the same variety，also its stability and the persistence were the best.For pecking rate，‘American No.Eight’ apple was 0.44%,‘Gala’ apple was 0.16%,and ‘Red Fuji’ apple was 0.20%.The second was biological insecticides，for pecking rate，‘American No.Eight’ apple was 1.92%,‘Gala’ apple was 2.24%，and ‘Red Fuji’ apple was 1.52%；the third was ultrasonic，for pecking rate，‘American No.Eight’ apple was 9.64%,‘Gala’ apple was 5.56%，and ‘Red Fuji’ apple was 3.24%；The vane wheel`s stability and persistence was the worst,and the pecking rate of ‘American No.Eight’ apple was 10.00%,‘Gala’ apple was 6.52%，and ‘Red Fuji’ apple was 2.60%.The comprehensive survey results of three different varieties showed that the pecking rate of early maturity apple was the highest，next was middle maturity apple,and the lowest was the late maturity apple.
