摘　　要：[目的]研究栽培模式对冬小麦生长指标及产量的影响。[方法]采用随机排列的方法对9种不同栽培模式进行比较试验,并对影响产量的相关因素进行观测。[结果]结果表明:栽培模式的改变影响了小麦群体冠层温度、旗叶的叶绿素含量和干物质的积累,进而影响产量。产量较高模式其播幅与幅间距的比依次为24.0 cm∶20.0 cm,30.0 cm∶26.6 cm和40.0 cm∶30.0 cm。[结论]通过改变传统小麦条播形成宽幅撒播种植模式是实现小麦增产、提高粮食产量的有效途径。[ Objective ] The aim was to study the influence of the cultivation modes on yield and growth index of winter wheat. [ Method ] Com- parison experiments of nine cultivation modes were studied by using the method of random arrangement. The related factors influencing the pro- duction were observed. [ Result] Results show that the cultivation mode changes affect the winter wheat canopy temperature group, flag leaf chlorophyll content and dry matter accumulation, which further influence yield. The better ratio of its width of furrows for sowing and the spac- ing was followed by 24.0 cm： 20.0 cm, 30.0 cm： 26.6 cm and 40.0 cm： 30.0 cm. [ Conclusion] Wide broadcasting pattern is the effective way to realize the wheat production, increase food production.
