| 摘 要： | 对水稻乳苗抛栽和手插秧、抛秧、水直播的干物积累与分配进行了分析。结果表明，不同群体经济产量与总干物质积累量、抽穗期至灌浆期的干物质积累速度之间的正相关达极显著水平，与抽穗前干物质积累量的正相关未达显著水平，与抽穗后的干物质积累量呈极显著正相关。水稻乳苗抛栽干物质积累速度低，抽穗灌浆期至成熟期绿叶和茎鞘干重比例较高，抽穗后干物质积累量低。 |

| Abstract: | This paper has studied dry matter accumulation and dry matter distribution of different rice populations. The results shows a very significant difference between economical yield and total dry matter accumulation and a very significant difference between economical yield and speed of dry matter accumulation from heading stage to tilling stage. The results also shows a very significant difference between economical yield and dry matter accumulation after heading stage. The speed of dry matter accumulation and dry matter accumulation after heading of nursing seedlings scattering (NSS) were lower. |
