摘　　要：晋太182是近年选育的适于山西省中部晚熟冬麦区种植的优质中筋小麦新品种。为了探索其植株高度受播期和播种密度影响的变化规律,采用二因素(播期、播种密度)随机区组设计,对晋太182植株高度变化进行试验,并与2010—2011,2011—2012年度山西省中部晚熟冬麦区区域试验水地组试验结果一起进行研究。结果表明,播期和播种密度对晋太182植株高度的影响均达到极显著水平,播期与播种密度互作对植株高度的影响不显著;晋太182植株高度随着播期的推迟而显著降低,随着播种密度的加大而显著增高;在同一播期内,晋太182植株高度随着播种密度的加大而增高;在同一播种密度下,植株高度随着播期推迟而降低。The new wheat variety of Jintai 182 with high- quality of medium gluten wheat was suitable for planting in the middle of Shanxi province and late maturing winter wheat area. In order to explore the plant hight affected by effect of sowing date and planting density, two factor randomized block was design, and combined with the 2010- 2011, 2011- 2012 annual regional test of late- maturing winter wheat area in the middle of Shanxi province. The results showed that the effects of sowing date and planting density on the plant height of Jintai 182 were significant. But interaction between sowing date and planting density on plant height was not significant. The plant height of Jintai 182 significantly decreased with the delay of sowing date. In the same sowing date, the plant height of Jintai 182 increased with the increase of planting density. Under the same sowing date, the plant height of Jintai 182 increased with increase of planting density. Under the same planting density, plant height decreased with delaying of the sowing date.
