| 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。 |
| 关 键 词： | 轮作 作物生产力 坡耕地 水土流失 养分流失 |

| 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 ... |
| Keywords: | crop rotation crop productivity slope farmland water and soil erosion nutrient loss |
