摘　　要：分析落阵营中心林场油松人工林主要病害的发生情况,结合实际情况积极开展综合性防治措施,旨在降低病害率。本试验在山西省大同市云州区倍加造镇进行,对标准样地的油松人工林病害情况进行调查,总结主要病害基本情况,根据防治措施差异设置不同的处理,营林改造(Z1)营林改造+化学措施(Z2)营林改造+化学措施+生物防治技术(Z3),分析不同防治方案的具体效果。结果表明,落阵营中心林场油松人工林病害主要包括:松落针病、松赤枯病、松叶枯病、其他类型,比例分别是38.36%、30.69%、28.95%、2%;Z3的综合防治后,落阵营中心林场油松人工林的成活率不断提升,病害率不断下降;Z3处理和Z2处理的优质和健康小班个数多于其他处理,亚健康和不健康小班个数少于其他处理;Z3处理的油松人工林植被物种多样性各项指数优势更明显;落阵营中心林场油松人工林的病害趋于多样化,需开展综合性防治,降低病害率,Z3的一体化的防治措施,效果明显,可大范围推广和实施。This study analyzes the occurrence of major diseases in Pinus tabuliformis plantations at the Luozhenying Central Forest Farm and explores comprehensive prevention and control measures aimed at reducing disease incidence.The experiment was conducted in Baijiazao Town,Yunzhou District,Datong City,Shanxi Province,where disease surveys were carried out in standard plots of Pinus tabuliformis plantations to summarize the prevalence and characteristics of major diseases.Based on differences in control measures,three treatments were implemented:forest modification(Z1),forest modification+chemical measures(Z2),and forest modification+chemical measures+biological control technology(Z3).The effectiveness of these different control strategies was evaluated.The results indicate that the primary diseases affecting Pinus tabuliformis plantations in the study area include Dothistroma needle blight(38.36%),pine red ring rot(30.69%),pine needle cast(28.95%),and other diseases(2%).The integrated Z3 treatment significantly improved the survival rate of Pinus tabuliformis plantations and reduced disease incidence.The number of high-quality and healthy stands in the Z3 and Z2 treatments was higher than in other treatments,while the number of sub-healthy and unhealthy stands was lower.Furthermore,the Z3 treatment exhibited a more pronounced advantage in vegetation species diversity indices.The increasing diversity of diseases in Pinus tabuliformis plantations highlights the need for comprehensive disease control strategies.The Z3 integrated control approach has demonstrated remarkable effectiveness in reducing disease incidence and improving stand health,making it highly suitable for large-scale application and promotion.
