摘要: 为给杂交小麦强优势组合创制及高产栽培技术研究提供参考依据,笔者总结了杂交小麦产量形成过程中的产量构成及其贡献、光合优势及物质生产、群体结构建成、源库关系、根系发育等生物学规律,提出了通过挖掘穗粒数及粒重潜力、扩大库源比、提高资源利用效率、实施精量栽培等进一步挖掘小麦强杂种优势的策略,以期为加速杂交小麦走向生产应用提供指导。

Abstract: In order to provide a reference basis for the creation of strong advantage combinations and the study of high-yielding cultivation technology of hybrid wheat, the author summarizes the biological rules, which include yield components and contributions to grain yield, heterosis of photosynthetic performance and matter production, population structure, source-sink relationships, root development and so on, in the process of yield formation of hybrid wheat. The author puts forward the main strategies to further exploit the heterosis of wheat, including the excavation of potential of grain number per spike and 1000-grain weight, increase in sink-source ratio, improvement of sink-source ratio, application of precision cultivation and so on. It is hoped to provide guidance for accelerating the application of hybrid wheat.
