土壤磷素流失
1.
The soil phosphorus loss mechanism was studied to develop a convenient assessment method.
土壤磷素流失强度评价对于控制面源磷素流失,降低受纳水体富营养化程度极为重要。
3) Soil and nitrogen losses
土壤与氮素流失
5) soil phosphorus
土壤磷素
1.

黄土旱塬长期定位施肥对土壤磷素分级、空间分布及有效性的影响
2.
Experiments of field runoff plots,which were conducted at vegetable plots in Hongsheng town of Wuxi city—the typical region of Taihu Basin,were designed to assess the effects of different rainfall intensities on soil phosphorus runoff loss from vegetable plots by artificial rainfall simulations.
以太湖流域典型区域无锡市近郊区鸿声镇的蔬菜地为研究对象,采用人工模拟降雨的方法,通过野外径流小区试验,研究了不同雨强对菜地土壤磷素径流流失的影响。
3.
The effects of different phosphorus levels (0,30,75,150kg/hm2) on characteristics and forms of soil phosphorus loss in runoff by artificial rainfall studied.
结果表明,不同形态磷素随降雨-径流过程的变化趋势基本一致,即初始阶段浓度大且下降速度快,,大约产生径流20min后,浓度下降变得缓慢,直到最后趋于稳定;在整个降雨-径流过程中,颗粒态磷(PP)占总磷(TP)72%~87%,是土壤磷素径流流失的主要形态。
