| 摘 要： | 以汕优63、Ⅱ优162、Ⅱ优419、K18A/149和65002为材料,在云南省涛源乡、宾川县和杭州市富阳县进行试验,分析了水稻高产的物质生长特性,并比较了不同环境下物质生长特性的差异及原因。结果表明:云南涛源和宾川产量分别比杭州高80%和66%,导致云南产量较高的主要原因是生物产量较高。生物产量差异主要在幼穗分化以后,尤其是灌浆结实期。在云南生态条件下,中后期能容纳较高的叶面积系数(LAI),群体生长速率(CGR)较高,使花后物质生产量大,且花后物质运转量也较高。 |
| 关 键 词： | 水稻 产量 群体生长速率 运转量 |

| Abstract: | 5 different type rice varieties were planted at Taoyuan Township,Binchuan County in Yunnan province and Fuyang county in Hangzhou city of Zhejiang province.The differences of the traits of matter production under different environments of rice were compared.The grain yield at Taoyuan Township and Binchuan county were 80 percent and 66 percent higher than that at Fuyang county.Higher biomass of rice at Yunnan was the reason of higher grain yield.The main difference of dry matter production was shown from panicle initiation stage to maturity,especially after flowering stage.At Yunnan province,after rice panicle initiation the plant could hold out higher leaf area index(LAI),and higher crop growth rate(CGR),and more matter of leaf and stem were translated to panicle.It leads to a higher grain yield. |
| Keywords: | rice grain yield crop growth rate translated matter |
