摘　　要：光能在作物进行光合作用和籽粒产量形成中起着重要作用。随着我国种植结构和区划的调整,间套作种植模式在一些适宜地区得到广泛应用,增加了农田生产力。然而,间套作种植方式下,由于受高位作物荫蔽影响,低位作物在某一生长阶段常常处于弱光胁迫环境中。弱光胁迫不仅会引起作物生长发育不良,而且会制约作物产量的提升。本文以间套作荫蔽环境下的大豆源库关系为例,综述了弱光胁迫调节作物源库器官生长发育的国内外研究现状;阐述了源库协调与作物产量之间的关系以及现有间套作作物产量研究概况与存在的不足;探讨了未来间套作种植下作物在源库关系与产量研究的发展方向。Solar radiation is very important in crop photosynthesis and grain yield formation.As the adjustments of planting plan,crop intercropping in the traditional farming system had been popularized and applied in some suitable areas,which enhanced farmland productivity.However,in the intercropping system,the lower crops were grown in a shaded environment created by higher crops,with deficient light interception in some growing stages.Shade stress inhibited the potential of lower crops and decreased their grain yield greatly.This paper presented the source and sink relations of soybean as an example based on shade stress condition in the intercropping system.Firstly,the research progress on organ growth and development of source/sink under the shade stress was reviewed.Secondly,the relationship of source-sink coordination and crop yield was summarized.Finally,the perspective researches on the relationship between crop yield and source-sink relation in intercropping system were analyzed.
