| 摘 要： | 研究了不同群体最大叶面积指数、单位叶面积生产能力与产量的关系，分析提出以提高单位叶面积生产能力为中心的小麦源库协调栽培途径，即在适宜光合源基础上，扩大群体总库容、提高单位叶面积负担的粒数，增加开花后干物质积累量，实现高的单位源生产能力，从而获得高产。

| Abstract: | The relationship between grain yield and maxinium LAI and grain weight produced by unit leafarea in wheat(Triticum aestivum L)was studied. The approach raising grain weight produced by unit leafarea was mainly analysed. The cultural approach to coordinate source and sink was that increasing grain num-ber loaded by unit leaf area by enlarging total sink capacity on the basis of optical photosynthetic source andraising accumulated dry matter after anthesis by delaying leaf senescence and strenthening the leaf activitycould increase grain weight produced by unit leaf area, which resulted in high grain yield. |
