| 摘 要： | 为了解广两优676作再生稻超高产栽培的产量结构特征,调查分析了不同产量水平的产量构成因素。结果表明,在产量4个构成因素中,再生稻头季以每穗粒数的变异最大,与产量相关最密切,对产量的贡献率最高,其次是每平方米穗数;再生季则以每平方米穗数的变异最大,与产量相关最密切,对产量的贡献率最高,其次是每穗粒数。再生稻要获得高产,头季应主攻大穗,而再生季则应培育多穗,以形成巨大的库容量。

Characteristics of Yield in Guangliangyou 676 of Ratooning Rice under Super High-yielding Cultivation |
| |
| Abstract: | In order to study on characteristics of yield under super high-yielding cultivation in Guangliangyou 676 of ratooning rice, yield components were investigated and analyzed in various levels of yield. The results showed that in four factors for rice yield, spikelets per panicle had larger variations and correlated significantly with yield, and secondarily panicle numbers per square meter per year in main crop. But in ratoon crop, panicle numbers per square meter per year had larger variations and correlated significantly with yield in main crop, and secondarily spikelets per panicle. In a word, big panicle in main crop and multiple panicles in ratoon crop is a key factor to increase the sink capacity and achieve high yield of ratooning rice. |
