铜仁地区不同摞荒桃园病虫害调查及绿色防控技术研究
Green Control Technology Research and Diseases and Pests Investigation on Abandoned Peach Orchard in Tongren Area
摘要
Abstract
To guide peach farmers in implementing biological control of major peach tree diseases and pests,promote the application of green control technologies,reduce pesticide residues in peach products,enhance the green and healthy quality of peach products,and effectively protect both the ecological environment and consumer health,fixed-point random sampling was conducted to investigate the disease conditions in different abandoned peach orchards.Ecological analysis methods were employed to examine the diversity and community similarity of peach tree diseases and pests in Yinjiang County and Bijiang District,thereby revealing the types of the main disease and pest,as well as characteris-tics of communities in the region.The results indicated that there were 9 dominant diseases and pests in Yinjiang County and 11 in Bijiang Dis-trict.No significant differences were observed in the Shannon-Wiener index,species richness index,Pielou index,or Simpson index between corresponding sample plots in the two regions.Analysis of the proportion of disease and pest species within each plot revealed that the types and distributions of diseases and pests varied across different abandoned orchards in various regions,and even within different plots of the same re-gion.The occurrence of diseases and pests may be influenced by factors such as the geographical location of the orchard,growth environment,temperature,light intensity,ventilation conditions,farmers' management practices,and the peach tree variety.Therefore,for the green con-trol of peach tree diseases and pests,it is recommended to first implement integrated management strategies based on the specific disease char-acteristics of each orchard,introduce or plant species that attract natural enemies of pests for habitat establishment,and strengthen orchard management by timely removal and pruning of diseased branches to reduce the risk of infection.Secondly,entomopathogenic fungi or other bio-logical agents can be applied to enhance the resistance of peach trees.Finally,microbial and botanical pesticides should be rationally utilized to control specific diseases.关键词
