摘　　要：在中等施肥水平（纯N 7.36 kg/667m2）下采用油菜育苗移栽、开行点播、条播和撒播,667m2相应密度分别为4 167株、1万株、2.2-2.4万株和2.3-2.5万株的情况下,贵州思南塘头和安顺兴隆两地试验油研10号产量水平分别为165.0-175.0 kg/667m2和208.1-232.4 kg/667m2,产量间差异不显著,但点播、条播和撒播比育苗移栽用工减少7.29-10.56个/667m2,总投入减少130.67-173.72元/667m2,单位面积纯经济效益比育苗移栽高79.27-151.32元/667m2。单位劳动生产率比育苗移栽高16.88-30.45元/个工。点播、条播和撒播经济效益显著。Four different planting patterns including dibbling（10000 plant/667m2）,drilling（22000～24000 plant/667m2）,broadcast（23000～25000 plant/667m2） and seedling transplant（4167 plant/667m2） were tested under 7.36 kg/667m2 of pure nitrogen in Sinan county and Anshun city to investigate the effects on yield of Youyan 10 and its economic benefit.The yields of Sinan county and Anshun city were 165.0～175.0 kg/667m2 and 208.1～232.4 kg/667m2 respectively.There was no significant difference between different planting patterns in yield at the same location but the total input of the drilling,dibbling and broadcast transplant patterns was 130.67～173.72 yuan/667m2 lower than the seedling transplant pattern and their economic benefit was 79.27～151.32 yuan/667m2 higher than the seedling transplant pattern.
