摘要

在丹江口库区习惯施肥条件下

比较坡耕地不同轮作系统的作物生产力及农田水土和养分流失的差异。结果表明

在5种轮作模式中

作物生产力水平以小麦-玉米轮作最高

生产效益以油菜-玉米轮作最高;农田产流量、土壤侵蚀量和磷钾养分流失量均以小麦-玉米轮作最小

小麦-芝麻轮作最大;而氮流失量以油菜-玉米轮作最小

以小麦-芝麻轮作最大。因此

小麦-玉米轮作为丹江口库区坡耕地适宜的环保型作物复种模式。

Abstract

Comparison of the crop productivity

water and soil erosion and nutrient loss from runoff was conducted in different rotation patterns on slope farmland under farmer's common fertilization practice in Danjiangkou reservoir area.The results showed that

the highest crop productivity and the highest economic income were obtained in 'wheat-maize' and 'oilseed rape-maize' pattern

respectively

amongst the five rotation patterns;The total amount of runoff and soil erosion

and the amount of total phosphorus(TP) and ...
