摘　　要：为分析济南市油松病虫害综合绿色防治技术的应用效果。于山东省济南市某林场油松种植样地开展油松病虫害综合绿色防治技术应用效果分析的试验调查,根据不同防治技术分为不同处理,CK(对照组,不采取任何防治技术)、T1(物理防治技术)、T2(物理防治技术+生物防治技术)、T3(物理防治技术+生物防治技术+化学防治技术),对比不同处理的油松病虫害绿色防治效果。结果表明:T3处理油松立枯病、白粉病、松针锈病的病树率和病情指数显著低于其他处理(P<0.05),综合防治率高于其他处理(P<0.05)。防治30 d后3个处理的油松松大蚜、松梢螟、松材线虫病和油松毛虫等虫害防治效果无显著差异(P>0.05),防治60 d和90 d后,以T3处理的防治效果显著。T3处理的优质小班个数显著多于其他处理(P<0.05),亚健康和不健康的小班个数显著少于其他处理(P<0.05)。由此可知,目前山东省油松病虫害的防治现状不容乐观,采取不同类型的防治措施均有一定的防治效果,其中物理防治+生物防治+化学防治的综合绿色防治技术效果最为明显。也由此提示在油松病虫害防治中需结合地域特点和病虫害类型及趋势制定切合实际的绿色防治对策,以达到减少油松病虫害率,促进林木生长的目的。This study investigated the application effect of integrated green control techniques of Pinus tabulates in Jinan,Shandong province.An experimental investigation was carried out on the application effect analysis of integrated green control techniques for Pinus tabulates pests and diseases in a forest plantation sample in Jinan City,Shandong Province.The study was divided into different treatments based on the control techniques applied:CK(control group,no control techniques applied),T1(physical control techniques),T2(physical control techniques+biological control techniques),and T3(physical control techniques+biological control techniques+chemical control techniques).The green control efficacy of these treatments on diseases and insect pests in Pinus tabulates was compared.The results indicate that the T3 treatment significantly reduced the disease incidence rate and disease index of Pinus tabulates for fusarium wilt,powdery mildew,and pine needle rust compared to other treatments(P<0.05).Additionally,the comprehensive control efficacy of the T3 treatment was significantly higher than that of the other treatments(P<0.05).At 30 days post-treatment,there were no significant differences in the control efficacy against pests such as Cinara pinitabulaeformis,Dioryctria splendidella,Bursaphelenchus xylophilus,and Dendrolimus tabulaeformis among the three treatments(P>0.05).However,at 60-and 90-days post-treatment,the T3 treatment demonstrated significantly superior control efficacy.The number of high-quality sub-compartments in the T3 treatment was significantly higher than that in the other treatments(P<0.05),while the number of sub-healthy and unhealthy sub-compartments was significantly lower(P<0.05).From the above findings,it is evident that the current status of disease and pest control for Pinus tabulates in Shandong Province is not optimistic.While various control measures have shown certain levels of efficacy,the integrated green control techniques combining physical,biological,and chemical methods has demonst
