为探明不同种植方式与黔油28号产量及经济效益之间的关系,以双低油菜黔油28号为材料,采用单因素随机区组试验设计,研究了免耕移栽、翻耕移栽、免耕穴播、免耕条播等4种不同种植方式对油菜产量及经济效益的影响.结果表明；1)油菜的生育期存在差异,移栽比直播油菜生育期长；2)油菜的产量存在显著差异,翻耕移栽产量最高,免耕条播产量最低；3)油菜的经济效益存在差异,其中,免耕移栽、免耕条播和免耕穴播用工比翻耕移栽的用工少27～114个/hm2,总投入减少1080～4640yuan/hm2,油菜的纯利润从高到低依次为免耕穴播＞免耕移栽＞免耕条播＞翻耕移栽.%To ascertain the relationship of different planting patterns on output and economic benefits of Qianyou 28, the effects of four different planting patterns (no-tillage transplanting, ploughed before transplanting, no-tillage bunch planting, no-tillage drilling)on rapeseed yield and the economic benefits were studied with Qinyou 28 as material, by the single factor randomized block design. The results showed that: 1) The growth stage of rape was different,the transplanted rape was longer than the direct-seeding rape on growth season. 2) There were significant differences of output among the different planting patterns. The ploughed before transplanting Output was the highest while the no-tillage drilling output was the lowest. 3) There were differences of economic benefits among different planting patterns. The labor cost of no-tillage transplanting, no-tillage drilling, no-tillage bunch planting was 27~114 labor/ hm2 fewer than that of ploughed before transplanting and the total input was reduced by 1 080 ~ 4 640 Yuan/hm2. The net profits of the four planting patterns from the highest to the lowest were no-tillage bunch planting >no-tillage transplanting>no-tillage drilling>ploughed before transplanting.
