为研究南方红壤坡耕地油菜-玉米轮作模式氮磷养分地表径流损失对不同耕作方式的响应机制,本文采用田间定位试验的方法,研究坡耕地顺坡垄作(CK)、横坡垄作(T1)、横坡垄作+秸秆覆盖(T2)、顺坡垄作+秸秆覆盖(T3)4个处理模式连续2 a对坡耕地氮磷养分地表径流损失的影响。结果表明:不同处理地表径流总量与氮磷流失总量均呈现出CK>T3>T1>T2,横坡垄作和秸秆覆盖处理均能有效降低坡耕地地表径流量和径流液中氮磷养分含量,其中T2处理对控制地表径流及氮磷损失的效果最好,较其他处理分别降低地表径流量、氮和磷流失总量24.46%~74.90%、39.60%~86.37%和36.84%~79.66%;坡耕地氮素流失以硝态氮为主,不同处理下...

To study the response mechanism of surface runoff loss of nitrogen(N)and phosphorus(P)nutrients during rapeseed and maize rotation using different tillage methods in red sloping farmland located in southern China, the field positioning test was used to examine the effects of slope ridge cultivation(CK), cross slope ridge cultivation(T1), cross slope ridge cultivation + straw mulching(T2), and along slope ridge cultivation + straw mulching(T3)on the surface runoff loss of N and P for two consecutive years. The total surface runoff of N and P wit...
