Nitrate-N Leaching in 23-Year Winter Wheat Field Combined with Application of Nitrogen and Phosphorus

, 2009
利用长期肥料定位试验,监测旱地农田土壤硝态氮的淋溶动向,研究施肥量与硝态氮累积量之间的关系,为科学施肥提供参考。【方法】在试验小区0～300cm土壤剖面中,每20cm深度取一个土样,1mol·L-1KCl浸提后以AA3连续流动分析仪测定硝态氮含量。【结果】单施氮肥土壤硝态氮累积峰出现在80～100cm土层和300cm以下土层,当施氮量达到180kg·hm-2·a-1时,0～300cm土层硝态氮累积总量相当于8年的施氮量。单施磷肥对土壤硝态氮分布无影响;氮 ...

夜间增温和施氮对两种川西亚高山针叶树根系分泌物的影响研究

, 2013
针叶林生长季短、低温和低N有效性常常抑制植物的生长和C、N的矿化作用。以全球气候变暖为主要特征的全球气候变化已经并正在改变着陆地生态系统的结构和功能，且不同N素水平(施氮和不施氮) 条件下，全球气候变化对地下生态过程的重要影响日趋突显。至今，模拟气候变化对针叶林生态系统地下生态过程中根系分泌物的影响仍鲜见报道。这种气温的升高和氮素输入的改变将直接或间接地影响到植物根系分泌物的释放，并极可能显著地影响着地下生态系统的根际过程物质循环及其对气候变化的反馈 ...

氮素富集情景下窄叶鲜卑花灌丛根系分泌物输入及其介导的土壤氮过程研究

, 2017
为探究高寒灌丛生态系统根系分泌物及其诱导的土壤生态学效应对大气氮沉降的响应规律，本文以青藏高原东缘窄叶鲜卑花(Sibiraea angustata)灌丛为研究对象，采用根系分泌物野外原位收集法，分析不同施氮水平(对照N0; 低N处理N5= 5 g N?m-2?a-1; 高N处理N10= 10 g N?m-2?a-1)对根系分泌物、土壤理化特征、微生物生物量及其胞外酶活性的影响。结果表明: (1)窄叶鲜卑花根系分泌物速率表现出明显的季节性动态变化，具体表现为8月>6月>10月，并呈现出与5 ...
