摘要

以8个水稻品种(组合)为材料，研究了留桩高度对再生稻源库流特性的影响。根据不同留桩高度下再生稻产量，将供试品种分为3种再生类型：高桩再生型、低桩再生型和中高桩再生型。留桩高度降低，再生稻有效穗数减少而每穗粒数增加，而低桩再生型品种每穗粒数增幅更大；高桩与中高桩再生型品种再生稻叶面积指数以高桩处理最大，而低桩再生型品种随留桩高度下降而增大；高桩再生型品种灌浆期光合速率以中、高桩处理较大，中高桩与低桩再生型品种齐穗期以高桩处理最大，齐穗后10 d和20 d以中低桩处理较大；高桩再生型品种再生稻作物生长率以高桩处理最高，而中高桩、低桩再生型品种以低桩或中桩处理最高；中高桩与低桩再生型品种再生稻枝梗过氧化氢酶活性随留桩高度下降而增强，而高桩再生型品种表现相反；高桩再生型品种茎鞘碳水化合物转运率以高桩处理较高，而低桩再生型品种以中、低桩处理较高。可见，留桩高度对再生稻源库流特性的影响与品种的再生类型密切相关。

Abstract

The characteristics of source, sink and flow of ratooning rice with different stubble heights of the main crop were studied with eight rice varieties as materials. According to yield of ratooning rice with different stubble heights of the main crop, the eight varieties were classified into three ratooning types, such as highstubble type (HST), lowstubble type (LST) and high/mediumstubble type (HMST). Decline of the stubble height resulted in decreased number of effective panicles and increased grain number per panicle in ratooning rice, especially for the grain number per panicle in ratooning rice of LST varieties. The leaf area index in ratooning rice of HST and HMST varieties was the highest under the high stubble treatment (40 cm), whereas that in ratooning rice of LST varieties increased with the decline of the stubble height. The leaf photosynthetic rates from full heading to 20 days after full heading in ratooning rice of HST varieties were higher under the medium (20 cm) or high (40 cm) stubble treatments, whereas the leaf photosynthetic rates at the full heading stage in ratooning rice of HMST and LST varieties were higher under the high stubble treatment and those at 10 days and 20 days after full heading were higher under the medium (20 cm) or low (10 cm) stubble treatments. The crop growth rates of ratooning rice of HST varieties were the highest under the high stubble treatment, whereas those of HMST and LST varieties were the highest under the low or medium stubble treatments. The activity of catalase in rachis branches of ratooning rice of HMST and LST varieties improved with declining stubble height, whereas a contrary trend was observed for HST ones. The transport rates of carbohydrate in stems and sheathes of ratooning rice of HST varieties were higher under the high stubble treatment, and those of LST ones were higher under the low and medium stubble treatments. These results indicate that the effect of stubble height of the main crop on characteristics of source, sink and flow of ratooning rice were closely related to ratooning types of rice varieties.

Key words： ratooning rice; stubble height; sourcesink characteristics; assimilates transportation; ratooning type
