摘要

2010年5-9月降雨季

在鲁中山区种植春花生的坡地农田中进行野外降雨径流观测试验

研究了不同坡度下

施用普通复合肥(CCF)和纯控释肥(CRF)对地表径流液和径流泥沙中铵态氮、硝态氮、可溶性磷、颗粒态氮和磷、总氮和总磷的影响。结果表明

花生生长前期

与CCF相比

施用CRF的坡地地表径流中可溶性养分流失含量较低

其中铵态氮含量低5.0%~74.2%

硝态氮含量低3.9%~37.0%

可溶性磷含量低7.1%~94.1%;CRF处理径流中颗粒态氮和磷含量在花生生长前期低于CCF处理

花生生长后期CRF处理径流液总氮、总磷含量高于CCF处理;在整个监测期内

CRF处理径流中总氮和总磷含量低于CCF处理。不同坡度下

随着坡度的增大

CCF和CRF的径流养分流失量变化为15°>10°>5°>0°

表明在坡地条件下

CRF能维持作物生长后期较高土壤养分含量

有利于提高氮磷的利用效率

减少雨季氮磷地表径流养分流失

降低农业面源污染。

Abstract

Experiment was conducted in rainy season between May and September 2010.The laws and characteristics of ammonium nitrogen

nitrate nitrogen

particulate nitrogen and phosphorus

total nitrogen and phosphorus difference of two fertilizers were analyzed under different slopes of peanut growing season.The results showed that compared with common fertilizer

in the early reproductive stages

the nutrient loss content of controlled-release fertilizer was lower

ammonium nitrogen content was 5.0%~74.2% lower and nitrat...
