| 摘 要： | 合理密植是小麦生产中构建合理群体结构、夺取高产的重要栽培措施.分析了种植密度对小麦产量及其构成和群体质量的影响.分析表明:种植密度对小麦产量和群体质量有显著性的影响.种植密度的调整可以有效协调小麦单位面积穗数与穗粒数、千粒重的关系,进而获取高产；还可以有效控制小麦群体结构的变化,使之更加合理.

| Abstract: | Rational close planting is the important cultivation measure to achieve high yield and reasonable population structure. This article reviewed the influence of plant density on yield of wheat from grain yield, its components and population quality. These studies showed that: the effect of plant density on wheat yield and population quality indexes was significant. Plant density can coordinative the relations of the panicle per unit area, grain number per ear and 1000 grain weight to achieve high yield. It also controlled the changes of population structure effectively, to make it more reasonable. |
