摘要： 农田基础地力提升对于减施肥料和作物稳产高产有着重大现实意义。为了研究华北潮土区土壤基础地力情况，在河南省典型潮土区原阳县、周口市、夏邑县等不同肥力水平的土壤上，通过2年大田试验及统计分析方法，观测和分析小麦-玉米轮作体系下土壤基础地力变化。结果表明：2012年和2013年小麦季的基础地力贡献率分别为78.1%和76.7%，略高于玉米季的71.9%和74.4%；2012年和2013年两季作物的平均基础地力贡献率分别为74.5%和75.1%，低肥力和高肥力水平土壤的地力贡献率没有显著差异。因此，华北潮土区小麦玉米轮作下土壤基础地力贡献率在75%左右。

Abstract: The improvement of basic soil productivity is important to reduce fertilizer application rates and increase crop yield. In order to study the basic soil productivity conditions in fluvo-Aquic soil region, north China, the basic soil productivity were studied on typical fluvo-aquic soils at three sites (Yuanyang county, Zhoukou city and Xiayi county) of different fertilities under wheat maize rotation system by two-year field experiment and statistical analysis technique. The results showed that the contribution rates of basic soil productivity were 78.1% and 76.7% in the wheat season in 2012 and 2013, respectively, which were a little higher than that of the maize season of 71.9% and 74.4%; the mean contribution rates of basic soil productivity of the two crops were 74.5% in 2012 and 75.1% in 2013, the contribution rates had no significant difference between low fertility soil and high fertility soil. To sum up, the contribution rate of basic soil productivity in fluvo-aquic soil region, north China under the wheat-maize rotation was about 75%.
