摘要
[目的]为提高山核桃的产量提供技术指导。[方法]介绍了红腹松鼠对山核桃的危害特点,并研究了驱避剂——树宝对红腹松鼠的防治效果。[结果]近年来红腹松鼠在山核桃产区的危害呈加重趋势,常造成竹林、天然次生林林缘分布的山核桃减产85%～95%;驱避剂——树宝对红腹松鼠具有很强的驱避作用,在清除受害林木周围乔木和灌木的基础上,每年在树干50 cm以下涂刷2次树宝(7月中旬和8月中旬各1次)可有效避免红腹松鼠对山核桃的危害,防治效果达80%以上。[结论]该研究为控制红腹松鼠对山核桃的危害提供了新方法。
[Objective] The research aimed to provide technical guidance for enhancing the yield of Carya cathayensis.[Method] The damage characteristics of Callosciurus erythraeus Pallas to C.cathayensis were introduced and the control effect of repellent-Shubao on C.erythraeus was researched.[Result] In recent years,the damage from C.erythraeus in the production area of C.cathayensis was more and more serious and it often cause the yield of C.cathayensis distributed in the edge of bamboo forest and natural secondary forest to reduce by 85%~95%;the repellent-Shubao showed very strong repellent action on C.erythraeus.Based on clearing the arbors and shrub around damaged forest,the damage from C.erythraeus to C.cathayensis could be avoided effectively through brushing Shubao on the trunk under the height of 50 cm for twice annually and its control effect was over 80%.The first brushing was carried out in middle Jul.and the second brushing was carried out in middle Aug.[Conclusion] This research provide a new method for controlling the damage from C.erythraeus to C.cathayensis.
