摘要
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1 080～4 640yuan/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 transphinting, 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.
