摘    要:
研究了夏谷高矮秆品种茎叶和根的发育及物质积累变化,矮秆品种前期发育较早,开花后体内的营养输出和积累变化不明显,矮秆品种在拔节期追肥或拔节期和抽穗期分作2次追肥的效果最好,高秆品种则以抽穗期追肥的效果最佳。另外,直品种的行距密植具有较好的效果,高秆品种则适于宽行距适宜密度种植。

关 键 词:夏谷 发育特点 密度效应 肥水效应 矮杆品种 高杆品种 茎 叶 根

Abstract:
The developing characters and the effect of fertilizer and density on high and dwarf plant varieties of summer millet ( Setaria italica ( L.) Beauv.) were studied in this paper. It showed that the dwarf plant varieties developed in the early stage of growth and there was no differences in the dry matter translation and accumulation after flowering between two varieties.The dwarf variety should be given fertilizing at the joinding stage or at joinding and booting stages respectively, the high variety should be given fertilizing at the heading stage. Narrow row of high density should be adopted by dwarf plant,wider row of middle density should be dopted by high plant.
Keywords:summer millet  high plang  dwarf plant  development  density  fertilizing
