2)、YLY911 (RR1)和LY6326 (RR2)。结果表明，DR1、DR2和RR2
处理的周年水稻产量显著高于RR1处理，且DR1、DR2和RR2处理之间均无显著差异。与DR处理相比，RR
处理抑制了水稻分蘖期和幼穗分化期氮素和磷素的积累，促进了齐穗期至成熟期茎鞘、叶及植株氮素和磷
素的积累量，以及提高了茎鞘、叶的氮素和磷素转运量和转运率。此外，DR较RR处理在氮素和磷素的收
获指数和稻谷生产效率方面具有一定的优势。本研究可以为进一步解析再生稻种植模式的养分利用效率，
以及再生稻种植模式在双季稻区的推广提供重要的参考价值。

Abstract This research aims to study the effects of ratoon rice cropping patterns on rice yield, uptake and
utilization of nitrogen and phosphorus in double-season rice area. The field experiment involved two types of
cropping patterns: double-season rice
