摘要通过田间调查和土壤肥力指标分析，探讨了松辽平原玉米带黑土肥力退化的原因和机理。 - Soil organic matter can be regarded as one of soil fertility index , so manure culture and maize straw treatment is beneficial for soil fertility
土壤有机质可作为土壤肥力指标之一，所以采取有机肥培肥和秸秆还田的培肥模式，有利于培肥土壤，提高土壤肥力。 - Based on the two fertility indices , organic matter and total nitrogen , 73 typical soil samples collected from calcareous cultivated soils with different yield levels in 10 counties of henan province were divided into three categories in fertility by hierarchical clustering analysis
本文在河南省十个县市不同产量水平的石灰性耕作土壤上采集了73个典型样品，并根据土壤有机质和全氮量这两个肥力指标，用系统聚类的方法将供试土壤划分为高、中、低三种肥力类型。 - At present there are more reports on soil erosion by experts from home and abroad , but most of these reports were about simulation and research based on a single factor . there are little reports on soil erosion on entire watershed , adopted comprehensive research measures according to the principle of ecological system , especially on soil erosion from the intensive farming system on slope lands , watersheds exploited for agroforestry industry , as well as appraisal reports on soil fertility index
目前国内外学者有关水土流失的报道很多，但大多数以单一因素和模拟试验研究较多，而从生态系统角度出发，采用综合方法，在小流域尺度上研究水土流失规律较少；对小流域坡耕地综合农业措施水土保持效应和小流域综合开发利用过程中水土流失规律研究以及侵蚀土壤肥力评价的研究则更少。
