摘　　要：为探索杂交油菜黔油22号的轻型简化高效栽培技术,加快该品种的大面积推广应用,采用随机区组试验研究了移栽方式及移栽密度对黔油22号产量及生产效益的影响。结果表明:1)翻犁移栽与免耕移栽其产量表现差异不显著,二者与移栽密度互作的产量差异也不显著,但移栽密度对产量的影响达极显著水平。2)免耕移栽高密度(233.77kg/667m2)与低密度的单产(175.55kg/667m2)差异达极显著水平。3)翻犁移栽低密度生产的纯收入(为296.32元/667m2)较常规种植和高密度种植的分别提高46.43%和32.11%,免耕移栽高密度生产的纯收入(为582.20元/667m2)分别较常规移栽和低密度移栽的提高25.46%和31.62%。4)翻犁移栽生产成本高于免耕移栽,其单位纯收入及产出投入比均低于免耕移栽。To explore the efficient cultivation generalization and application, transplanting methods techniques of Qianyou 22, speed up its large scale and density were used as two factors in the trial with random completely block design. Results： 1） There was no significant difference on yield between different transplanting methods and also no significant difference on interaction between those two factors. However, there was significant difference on yield between different density. 2） There was very significant difference on yield between high density translanting and low density translanting with no tillage, the yield was 233. 77 kg/667m^2 and 175. 55 kg/667m^2, respectively. 3） The cost of production was higher on ploughed before transplanting than on no-tillage transplantin, but the net income and input output ratio were lower. 4） The net income was 296.32 Yuan on low density translanting, 46. 430//00 and 32.11%0 higher than conventional cultivation and high density translanting under ploughed before transplanting. 582. 20 Yuan was obtained in high density translanting, 25.46% and 32.11%higher than conventional cultivation and low density translanting under no-tillage.
