摘要: 【目的】明确内蒙古地区土壤线虫种类。【方法】对内蒙古赤峰市、呼和浩特市、乌兰察布市和鄂尔多斯市马铃薯、甜菜、玉米3种作物根围5~20 cm土壤进行采样,使用改良贝尔曼漏斗法进行线虫分离,对分离到的线虫进行鉴定,并进一步分析其多样性和分布情况。【结果】在内蒙古不同地区的10个地块中发现包括盆咽属(Panagrolaimus)、小杆属(Oscheius)、真滑刃属(Aphelenchus)、茎属(Ditylenchus)、类圆属(Strongyloides)、Auanema和拟丽突属(Acrobeloides)的线虫。【结论】通过对内蒙古地区土壤线虫种类进行调查发现,不同调查地区不同作物土壤线虫数量、种类都不同,研究结果为进一步监测内蒙古土壤线虫多样性和相关病害预防提供参考。

Abstract: 【Objective】To identify the species of soil nematodes in Inner Mongolia.【Methods】The nematodes were isolated by improved Behrman funnel method and identified through sampling of 5-20 cm root circumference of potato, sugarbeet and maize soil from Chifeng,Hohhot,Ulanqab and Ordos in Inner Mongolia . The diversity and distribution of nematodes were also analyzed.【Results】Genera of nematodes were isolated in 10 plots in Inner Mongolia, including Panagrolaimus, Oscheius, Aphelenchus, Ditylenchus, Strongyloides, Auanema and Acrobeloides.【Conclusion】Species and numbers of soil nematodes in different crops were different in different regions in Inner Mongolia, and the research results will provide reference for the further monitoring of soil nematode diversity and its control in Inner Mongolia.
