摘　　要：为了探索适宜重庆市坡耕地植烟的保护耕作措施,采用田间试验,研究了起垄方式和垄间覆盖物互作对坡地烟田土壤理化性状及烤烟经济性状的影响。结果表明:1等高线起垄和垄间覆盖秸秆、等高线起垄和垄间种植黑麦草组合的烟株主要农艺性状较好,有利于烟株的生长发育;2等高线起垄和垄间覆盖秸秆、等高线起垄和垄间种植黑麦草组合能有效改善土壤理化性状;3烤烟经济性状表现为处理组合等高线起垄和垄间覆盖秸秆、等高线起垄和垄间种植黑麦草的烟叶产量、产值及上等烟比例较高,表现较优。综合分析,在坡地上植烟时,采用等高线起垄和垄间覆盖秸秆、种植黑麦草方式,不仅能保障烤烟的长势和产值,还有利于保持土壤养分,改善土壤的理化性状。The objectives of this study were to investigate the influences of effects of ridging method and ridge covering interaction on soil physicechemical property of slope tobacco field and economic characters of flue-cured tobacco by field experiment to provide a theoretical basis for conservation tillage measures of Chongqing tobacco field slope area. The results showed that： （i） Agronomic characters of flue-cured tobacco of treatment combination contour ridging with straw mulching and contour ridging with planting rycgrsss were better, which help to grow and development for flue-cured tobacco. （ii）Contour ridging with straw mulching and contour ridging with planting ryegrass can improve physicechemical property of soil. （iii）Output value and the ratio of fine tobacco of flue-cured tobacco of treatment combination contour ridging with straw mulching and contour ridging with planting ryegrass were higher. Comprehensive comparison suggested that tobacco field slope by contour ridging and straw mulching and planting ryegrass can not only ensure the growth and output value of flue-cured tobacco, but also keep soil nutrients, improve soil physicochemical property.
