摘　　要：选取常规早籼稻、早熟籼型杂交稻和中熟籼型杂交稻代表品种4个,通过对参试品种实际产量、生育特征和光温资源利用水平等指标分析,筛选出沿江地区适宜机插再生稻品种,探究不同类型再生稻品种温光资源利用水平,为该生态区再生稻规模化示范推广提供参考。结果表明,中组143、株两优120、陵两优7713和丰两优香1号均适宜沿江地区再生稻种植,其中丰两优香1号年有效积温利用率和积温生产效率最高,丰两优香1号两季产量分别较中组143、株两优120和陵两优7713显著增产12.82%、19.90%和31.56%,但不同品种再生稻库源关系及稻米品质差异还有待进一步考察。Four representative varieties were selected to analyze the actual yield,growth characters,utilization level of light and temperature resources and other indexes.Ratooning rice varieties suitable for machine transplanting along the Yangtze River were screened.We explored the utilization level of temperature and light resources of different types of ratooning rice varieties,so as to provide references for the scale demonstration and promotion of ratooning rice in this ecological area.Result showed that Zhongzu 143,Zhuliangyou 120,Lingliangyou 7713 and Fengliangyouxiang 1 were all suitable to be planted in areas along the Yangtze River as ratoon rice.Among them,Fengliangyouxiang 1 had the highest annual effective accumulated temperature utilization and accumulated temperature production efficiency.The two season yield of Fengliangyouxiang 1 enhanced by 12.82%,19.90%and 31.56%,respectively,compared with Zhongzu 143,Zhuliangyou 120 and Lingliangyou 7713.However,further investigation was still needed for the rice quality differences and the relationship between sink and source of different ratooning rice varieties.
