超级稻深两优5814产量结构分析及其高产栽培技术

摘要

深两优5814是由国家杂交水稻工程技术研究中心清华龙岗研究所育成的籼型两系超级杂交稻新组合，本文对其产量构成因素及产量进行了统计分析。结果表明，各产量构成因素对产量的影响由大到小依次为每穗粒数>有效穗数>结实率>千粒重，据此提出了相应的高产栽培技术以发挥该组合的增产潜力。%Shenliangyou 5814 is a new two-line combination of indica super hybrid rice, cultivated by Tsinghua Longgang Institute of National Hybrid Rice Engineering Technology Research Center. The effects of yield components on yield were analyzed in this paper. The results showed that the effects of yield components on yield are grain numbers per panicle >effective panicles>seed setting rate>1 000 grain weight. Therefore, the authors proposed the corresponding high yield cultivation techniques in order to achieve the yield potential of the combination.
