Examples
- Through field investigation and soil fertility index analysis , causes and mechanism of fertility degradation of black soil in the songliao plain were explored
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。 - Through field investigation and soil fertility index analysis , causes and mechanism of fertility degradation of black soil in the songliao plain were explored
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。 - 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。 - Soil erosion and nutrient losses in jiangjiatang watershed in lanxi city in zhejiang province during exploitation was studied from 1993 - 2000 using adoptive research methods such as runoff plot , catchment area , and rare earth element tracer ( eu ) , and the soil fertility index appraisal . the major conclusions are as follow : 1 . the principle of water and soil losses together with nutrients and the forms in which they were lost were studied under different fanning systems in runoff plot
本研究选择浙江省中部金衢盆地边缘兰溪市水土保持监督站蒋家塘小流域为研究试验点，以协作单位兰溪市水土保持监督站小流域开发试验区为基础，采用坡面径流小区法、单源汇水试验区出口实测法、稳定性核素- eu土芯示踪法研究了2000年坡耕地不同农作措施水土流失规律及养分流失规律和小流域综合开发过程中水土流失规律及养分流失规律，并对小流域侵蚀土壤的肥力现状进行评价。
