摘 要 ：采用不同氮素配比及人为改变源库比例，对生育后期水稻穗颈节与基部节间的伤流进行了研究。结果表明，穗颈节与基部节间的伤流强度随生育期变化及伤流液中的氨基酸含量和种类等存在明显差异；库叶源调节对两者的影响差异甚大。说明穗颈节伤流不仅与根系活性有关，可能与叶片、茎鞘及库容活性也有密切联系。合理的氮素配比有利

Abstract:By different nitrogen treatments and manual regulation of source-sink ratio, dynamic states of bleeding at neck-panicle node and basal internode of rice were studied. There were very difference in dynamic changes and amino acids of bleeding. The effects of source-sink ratio regulations on them were
