| 摘 要： | 在黄土高原地区,夏季休闲期既是高温多雨期也是土壤微生物强烈活动期.研究该时期土壤呼吸变化与土壤水分、温度和施氮之间关系,有助于深入理解农田生态系统土壤呼吸的时空变异性及其影响因素.本研究以1984年设立在黄土旱塬区长期田间定位试验为平台,选取了5个不同施氮处理（N0、N45、N90、N135和N180）,于2009年夏...

| Abstract: | On the loess plateau,summer fallow season is a hot rainy time with intensive soil microbe activities.To evaluate the response of soil respiration to soil moisture,temporature,and N fertilization during this period is helpful for a deep understanding about the temporal and spatial variability of soil respiration and its impact factors,then a field experiment was conducted in the Changwu State Key Agro-Ecological Experimental Station,Shaanxi,China.The experiment included five N application rates: unfertilized... |
