在陕北枣林研究区域内,以土壤动物为研究对象,采取野外调查取样、定点动态观测与室内鉴定分类的研究方法,选取了延安万花山、延川县、清涧县、佳县枣林4个样点7个样地,于2007年3月、6月、9月、11月,对土壤动物功能类群进行了初步研究。陕北枣林土壤动物可划分为植食性、捕食性、腐食性、枯食性、菌食性土壤、杂食性土壤动物6个功能类群,基于土壤动物功能类群与枣林病虫害生态调控的内在关系,建构陕北枣林害虫生态调控体系,为深入探讨土壤动物与枣林害虫生态调控的关系提供基础资料和理论依据。
In the study area of Zaolin in North Shaanxi Province, taking soil fauna as the research object, taking the methods of field survey sampling, fixed-point dynamic observation and indoor identification classification, we selected Yan’an Wanhua Mountain, Yanchuan County, Qingjian County, Jiaxian Zaolin 4 plots of 7 plots, in March 2007, June, September, November, the soil fauna functional groups conducted a preliminary study. The soil fauna of jujube forest in Northern Shaanxi Province can be divided into six functional groups of herbivorous, predatory, carnivorous, necrotic, bacterioid soil and omnivorous soil animal. Based on the intrinsic relationship between functional groups of soil fauna and ecological regulation of jujubes, The ecological regulation system of jujube forest pests in northern Shaanxi provides the basic data and theoretical basis for further discussion on the relationship between the soil animal and the ecological regulation of jujube forest pests.
