Output response to fertilization development in rice cropping 稻作施肥制度进步的产量响应
2.
The nutrient role of different fertilizer application strategies was assessed by measuring c and n dynamics of soil microbial biomass in corn fields 摘要通过测定不同施肥制度下玉米土壤微生物量碳、氮的动态变化,探讨了不同施肥制度对玉米土壤的培肥效应。

The study also discovered that both the present fertilization system based on inorganic n and inorganic p and the present system of continuous cropping of corn had greats effect on balance of soil nutrients 研究还发现,现行的以无机氮磷肥为主的施肥制度和玉米连作种植制度对土壤养分平衡有很大影响。
