摘　　要：以常规栽培模式为对照(CK),设置施肥优化模式(FM)、耕层优化模式(TM)和耕层施肥优化模式(WM),研究优化栽培模式下油菜生长指标、干物质、产量变化的特征。结果发现:优化栽培显著提高了油菜株高、一次分枝数和角果长度,增加了各生育时期的干物质积累量以及单株角果数、角粒数和产量,其中以耕层施肥优化模式处理的油菜生长状况最好、干物质积累量最高,产量最高,比对照高出20.13%。因此,耕层施肥优化模式对油菜效果最好,可在生产中推广应用。This paper studies the variational characteristics of the growing index,dry matter,and yield of oilseed rape under the optimal cultivation mode,with the conventional cultivation mode as the control(CK),the optimal fertilization mode(FM),the optimal topsoil mode(TM)and the optimal topsoil fertilization mode(WM)is set up.The results demonstrate that optimal cultivation significantly increases the plant height,the number of primary branches,and pod length of oilseed rape,as well as raises the dry matter accumulation,pod number,pod grains,and yield per plant of oilseed rape in each growth period.Among them,with the best growth condition,the highest dry matter accumulation,and the highest yield of oilseed rape in the optimal topsoil fertilization mode,which is 20.13% higher than that of the control.Therefore,the optimal fertilization mode in the topsoil has the best effect on oilseed rape,it can be popularized and applied in production.
