与传统高产栽培管理比较，单位面积干物重、茎物质积累量和叶片的物质表观转出量高。
The dry matter weight per unit, dry matter accumulation per stem( panicle), and transportation of leaf apparent matter was more than the high yield crop management.
孕穗期小花数均与叶面积、叶片重、叶鞘重和总干物重呈显著或极显著正相关，而与茎高的相关不显著。
The floret number was significantly correlated with the weights of leaf, leaf sheath, whole main stem or tiller, and leaf area, but not with the length of stem.
