| 摘 要： | 采用群落种组成相似性分析、群落组成相似性分析和群落特征相似性分析3种方法,研究了安徽江淮地区早稻、中稻、晚稻3种稻型及分蘖、孕穗、乳熟3个生育期害虫-天敌群落的相似性.结果表明,群落种组成相似性平均水平的排序为同一稻型相邻生育期>同一稻型不同生育期>不同稻型相同生育期.早稻乳熟期与中稻乳熟期的群落组成最相似,其次为早稻孕穗期与晚稻孕穗期及乳熟期.早稻乳熟期与中稻乳熟期的群落特征也最相似,其次为早稻分蘖期与晚稻孕穗期.还对群落相似性的研究方法及安徽江淮地区的稻作制度进行了讨论.

| Abstract: | Three methods,namely,community species composition similarity analysis,community composition similarity analysis,and community characteristic similarity analysis,were employed to study the similarity of insect pest-natural enemy communities of three rice types(early rice,middle-season rice and late rice) and their three development stages(tilling stage,boot stage and milk stage) in the Yangtze-Huaihe region of Anhui Province.The results showed that the average levels of community species composition similarity was in the order of the adjacent development stages of the same rice types>the different development stages of the same rice types>the same development stages of different rice types.The community composition of the milk stage of early rice was most similar to that of the milk stage of middle-season rice,and the boot stage of early rice to both boot stage and milk stage of late rice secondly.The community characteristics of the milk stage of early rice was also most similar to that of the milk stage of middle-season rice,and the tilling stage of early rice to the boot stage of late rice secondly.In the same time,the research methods of community similarity and the rice planting system in the Yangtze-Huaihe region of Anhui were discussed. |
