为验证改变果袋外袋颜色是否可以降低鸟害影响,本研究于2013年和2014年对北京市延庆县佛峪口果园的部分苹果果实使用不同种颜色的果袋进行套袋处理。套袋总数:实验组1713,对照组1787。实验结果显示,果袋颜色与被鸟类破坏情况存在极显著差异(P<0.001),其中,钴蓝色果袋的防鸟害效果最好,破坏率为1.30%,其次是大红色和白色果袋,破坏率分别为2.11%和2.60%,均低于对照组原色果袋破坏率4.40%;黑色、群青色、熟褐色及青莲色的防鸟害效果较差,其破坏率分别为9.21%、8.60%、8.11%和6.90%,远高于对照组。建议今后生产中使用外袋颜色为钴蓝色的果袋。
In order to verify whether the change of the color of bags outside the bag can reduce the impact of bird diseases, this study bagged fruit bags of some colors with different colors on some apple fruits of Buddha Dayukou orchard in Yanqing County, Beijing in 2013 and 2014. Total bagging: experimental group 1713, control group 1787. The results showed that there was a significant difference (P <0.001) between the color of the bag and the damage caused by the birds. Among them, the anti-bird damage effect of the cobalt blue bag was the best with the destruction rate of 1.30%, followed by the reddish and white Fruit bag, the destruction rate was 2.11% and 2.60%, respectively, lower than the control group fruit bag destruction rate of 4.40%; black, ultramarine, mature brown and Qinglian anti-bird damage less effective, the damage rates were 9.21%, 8.60%, 8.11% and 6.90%, much higher than the control group. It is recommended to use the outer bag color cobalt blue fruit bag in the future production.
