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。
Jintai 182 is a new high-quality mid-gluten wheat variety suitable for planting late maturing winter wheat in central Shanxi Province. In order to explore the variation rule of plant height affected by sowing date and sowing density, two-factor (sowing date, sowing density) randomized block design was used to test the plant height change of Jintai 182, and the results were compared with those of 2010-2011 and 2011-2012 Annual Shanxi province late ripe winter wheat regional test water group test results together. The results showed that the effects of sowing date and sowing density on the plant height of Jintai 182 reached extremely significant levels. The interaction between sowing date and seeding density had no significant effect on plant height. The plant height of Jintai 182 decreased significantly with the sowing date , Which increased significantly with the sowing density. During the same sowing date, the plant height of Jintai 182 increased with the sowing density increasing. Under the same sowing density, the plant height decreased with the sowing date.
