- 摘要:
- 为了更好地防治园林植物寄生线虫，研究了园林植物云杉、杏树、东北连翘和榆叶梅植物根周土壤线虫群落，分析了土壤线虫群落在不同土壤深度的垂直分布特征。结果表明：试验期间共发现土壤线虫42个属，100 g干土中土壤线虫总数为17~178条，深层土壤线虫数量较少。杏树的优势营养类群为植物寄生线虫，其它3种植物的优势营养类群为食细菌线虫。4种植物共同优势属为Dolichorhynchus。线虫总数、植物寄生线虫数量以及食真菌线虫数量存在植物种类间差异。榆叶梅根周土壤的植物寄生线虫数量在土壤深度间存在显著差异。园林植物土壤线虫群落组成的研究可以为本地区植物寄生线虫防治提供理论依据。
- Abstract:
- In order to better control garden plant parasitic nematodes，soil nematode communities composition in root surroundings under Picea asperata,Prunus armeniaca,Forsythia mandshuric and Amygdalus triloba were researched.The vertical distribution characteristics were analyzed.The results showed that 42 genuses were founded.The total number of soil nematodes were 17~178 per 100 g dry soil,less nematodes were found in the deeper soil depth.The dominant trophic group of nematodes was plant parasitic nematode in Prunus armeniaca.While the dominant trophic group of nematodes was bacterivorous nematode in the other three plants.The dominant genus were Dolichorhynchus in soil of four landscape plants.There were significant difference among four plants in total number of soil nematode,plant parasitic nematode and fungivores.And there was significant difference in depth in plant parasitic nematode of Amygdalus triloba.The research provided the theoretical basis for the control of local plant parasitic nematode.
