摘　　要：试验研究秸秆还田与N肥施用对夏玉米干物质生产的影响结果表明,秸秆还田与N肥施用对夏玉米干物质生产有促进作用,且在一定程度上延缓夏玉米叶片衰老,延长叶片功能期,并促进夏玉米干物质由茎秆向籽粒的转运。The effects of crop residues incorporation and N-fertillzer on the dry matter of summer maize were studied. The recruits show that crop residues in corporation and N-fertilizer utilization can promote the matter production of summer maize,delay the decrepitude of summer maize＇s leaves in some degree, prolong the function period of leaves and increase the transportation ability of dry matter from stem to grain,

关 键 词：秸秆还田 N肥 叶绿素含量 干物质积累
