摘  要:
为了探讨不同农业环境条件下耕地土壤原生动物群落的演替状况,为土壤生物多样性保护和农业可持续发展提供更多的理论依据,研究了北方耕地常见的3种利用方式——常规大田、温室大棚和露天菜地下土壤原生动物的群落结构及其与土壤理化性质的关系。土壤原生动物群落分析结果表明,常规农田、1a温室大棚和4a温室大棚之间具有明显的演替梯度,在4a温室大棚中鞭毛虫丰度较高,这可能是由于常规农田中土壤翻耕引起了鞭毛虫数量下降。露天菜地内由于较多的肥料投入提高了纤毛虫的丰度。温室大棚和露天菜地这2种耕地利用方式都会强化土壤食物网细菌分解途径。

摘  要:
In order to protect soil biodiversity and maintain sustainable agriculture,an experiment was conducted to analyze the relationship between soil protozoa community and soil physico-chemical characteristics under three kinds of agricultural land use types——conventional wheat-maize rotation field,plastic greenhouse,and open vegetable field.The results of protozoa community analysis indicated that a succession gradient existed from the conventional field to the one-year plastic greenhouse,then to the fouryear one.Tillage brought about a decrease of flagellates in the conventional field,so there was higher abundance under the four-year plastic greenhouse.More ciliates occurred under the open vegetable field due to the increased fertilizer.Both of the plastic greenhouse and open vegetable field could strengthen the pathway of bacterial decomposing.
