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（233．77 kg／667m2）与低密度的单产（175．55 kg／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。
為探索雜交油菜黔油22號的輕型簡化高效栽培技術，加快該品種的大麵積推廣應用，採用隨機區組試驗研究瞭移栽方式及移栽密度對黔油22號產量及生產效益的影響。結果錶明：1）翻犛移栽與免耕移栽其產量錶現差異不顯著，二者與移栽密度互作的產量差異也不顯著，但移栽密度對產量的影響達極顯著水平。2）免耕移栽高密度（233．77 kg／667m2）與低密度的單產（175．55 kg／667m2）差異達極顯著水平。3）翻犛移栽低密度生產的純收入（為296．32元／667m2）較常規種植和高密度種植的分彆提高46．43％和32．11％，免耕移栽高密度生產的純收入（為582．20元／667m2）分彆較常規移栽和低密度移栽的提高25．46％和31．62％。4）翻犛移栽生產成本高于免耕移栽，其單位純收入及產齣投入比均低于免耕移栽。

To explore the efficient cultivation techniques of Qianyou 22,speed up its large scale generalization and application,transplanting methods 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/667m2 and 175.55 kg/667m2 ,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,46.43% and 32.11% 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.
