1·Ratooning rice is a type of rice with a special cultivating system.
摘要再生稻是一种特殊的水稻种植制度下的稻作类型。
2·Six rice combinations were used to study the source-sink characteristics of ratooning rice and its same-term tasselling main crop.
比较研究了再生稻与同期抽穗主季稻的源库特性。
3·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.
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；
4·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.
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。
5·The results showed that the differences of total yield between main cropping and ratooning cropping and ratooning rate among different rice varieties(combinations) were significant.
结果表明，不同品种（组合）头季稻加再生稻的产量之间存在显著的差异，供试材料间再生率的差异很大。
