摘 要:目的分析个旧市白云山国有林场天然次生林病虫害绿色防治措施,总结防治效果。方法样地选择个旧市白云山国有林场,根据病虫害绿色防治措施差异分为不同处理,A1(农业防治)、A2(农业防治+生物防治)、A3(农业防治+生物防治+物理防治),分析不同处理后的天然次生林病虫害绿色防治效果。结果A3处理次生林健康度的优质和健康个数多于A1和A2处理,亚健康和不健康个数少于A1和A2处理;林下物种多样性表现为A3>A2>A1;A3处理的群落层次更复杂、郁闭度最高、叶面积更大,病虫害清除更为彻底。结论个旧市白云山国有林场天然次生林病虫害类型较多,不同的防治措施均能起到防治效果,以农业防治+生物防治+物理防治的综合防治效果最佳,因此在病虫害防治过程中需掌握区域的环境变化和气候变化特点,掌握动态变化因子,结合病虫害的类型、病虫害发生规律等制定符合实际要求的绿色防治对策。实践中应当提高森林病虫害防范意识,完善森防体系建设,并少量应用清除虫害的化学药剂,通过各种绿色防治措施以及营造混交林、对林木进行抚育间伐等措施获得更为理想的病虫害防治效果,从而促进林木生长。Objective To analyze the green control measures of natural secondary forest diseases and insect pests in Baiyun Mountain state-owned forest farm in Gejiu City,and to summarize the control effects.Methods The samples were selected from Baiyunshan State-owned forest farm in Gejiu City and divided into A1(agricultural control),A2(agricultural control+biological control)and A3(agricultural control+biological control+physical control)according to the differences in green control measures of diseases and pests.The green control effects of natural secondary forest diseases and pests after different treatments were analyzed.Results The number of high quality and healthy of secondary forest health degree treated by A3 was more than that treated by A1 and A2,and the number of sub-healthy and unhealthy was less than that treated by A1 and A2.The species diversity of understory was A3>A2>A1.The level of community treated by A3 was more complex,the canopy was the highest,the leaf area was larger,and the pest and disease removal was more thorough.ConclusionThere are many types of diseases and pests in the natural secondary forest of Baiyun Mountain State-owned forest farm in Gejiu City,and different control measures can all play a role in the control effect.The comprehensive control effect of agricultural control,biological control and physical control is the best.Therefore,in the control process of diseases and pests,it is necessary to master the characteristics of regional environmental change and climate change,and grasp the dynamic change factors.According to the types of diseases and pests and the occurrence rules of diseases and pests,the green control countermeasures that meet the actual requirements are formulated.In practice,we should improve the awareness of forest disease and pest prevention,improve the construction of forest control system,and apply a small amount of chemical agents to remove pests,and obtain more ideal disease and pest control effect through various green control measures,construction of mixed for
