摘    要:本文针对玉米生长期内施用化肥对东北黑土地区线虫群落组成及多样性产生的影响进行了研究,共获得14科,16属,其中头叶科(Cephalobidae),小杆科(Rhobditidae) ,真滑刃属(Aphelenchus),垫刃属(Tylenchus)为优势科/优势度指数分析比较了施肥和不施肥试验小区土壤线虫群落多样性分布规律,其中Shannon多样性指数和丰富度指数是评价线虫群薄对化肥投入最敏感的指数。

关 键 词:玉米  长期  化肥  土壤线虫  群落组成  多样性  黑土地区

Abstract:The effects of chemical fertilizer on nematode community composition and diversity were investigated in a field throughout the corn growing season in the Black Soil Region, Northeast China. 14 families and 16 genera were observed. Cephalobidae, Rhabditidae, Aphelenchus , and Tylenchus were found to be the dominant families/genera. Significant differences were found between sampling dates ( p <0.01) and between treatments ( p <0.01) in the total number of nematodes during the study period. Ecological indices of diversity, evenness, richness and dominance and the dynamics of the nematode community were compared between the treatment and the control plot. Shannon index and richness were found to be more sensitive indicators than other ecological indices for assessing the response of nematode communities to the application of chemical fertilizer.
Keywords:corn  growing season  chemical fertilizer  soil nematode  community composition  diversity  Black Soil Region
