摘　　要：[目的]筛选出适宜的油菜品种和栽培密度来指导山地油菜生产。[方法]采用2015年油菜不同品种、密度的4因素4水平山地田间小区试验资料,研究不同品种和密度对山地油菜产量及其构成因素的影响。[结果]云南省保山市山地油菜品种可以大力推广云油双2号和花油8号,重点示范H148-1,淘汰A35。高产栽培的最适直播密度是14.67万~22.01万株/hm2。[结论]该研究为今后保山市和其他相似地区山地油菜高产栽培提供技术支撑。[Objective]To screen the proper rape variety and cultivation desnity to guide the production of mountain rape.[Method]By using the four factors and four levels test data of rape in 2015,we researched the effects of different varieties and densities on the yield and its component factors on mountain rape.[Result]Mountain rape in Baoshan City of Yunnan Province could vigorously promote Yunyoushuang 2 and Huayou 8,mainly demonstrate H 148-1,and eliminated A 35.The proper planting density of high-yield cultivation was 146 700-220 100 plants/hm 2.[Conclusion]This research provided technology support for the high-yield cultivation of mountain rape in Baoshan City and other similar areas.
