摘要/Abstract

摘要：

【目的】基于模型定量描述中熟籼粳杂交稻栽后植株磷素积累动态特征。【方法】以甬优中熟籼粳杂交稻甬优2640和甬优1640为试材,常规粳稻扬粳4038和扬粳4227、杂交籼稻新两优6380和扬两优6号为对照,研究甬优中熟籼粳杂交稻移栽后植株磷素积累特征及比较不同类型品种栽后植株磷素吸收利用特征差异。【结果】籼粳杂交稻产量和成熟期植株磷素积累量均显著高于常规粳稻和杂交籼稻。与常规粳稻和杂交籼稻相比,籼粳杂交稻籽粒吸磷量较高,磷素籽粒生产率则较低。籼粳杂交稻花后叶片磷素转运量低于常规粳稻和杂交籼稻,花后茎鞘磷素转运则介于二者之间。籼粳杂交稻栽后植株磷素积累动态以Gompertz方程拟合较好,常规粳稻和杂交籼稻则以Logistic方程拟合较好。籼粳杂交稻最大磷素积累速率高于常规粳稻和杂交籼稻。籼粳杂交稻、常规粳稻、杂交籼稻达到最大磷素积累速率的时间大致在栽后50~52、59~60和61~63 d。籼粳杂交稻在快增期和缓增期的磷素积累量显著高于常规粳稻和杂交籼稻,渐增期的磷素积累量则低于对照。籼粳杂交稻在快增期和缓增期的磷素积累速率和积累时间均高于常规粳稻和杂交籼稻。【结论】与常规粳稻和杂交籼稻相比,甬优中熟籼粳杂交稻在产量和成熟期植株磷素积累量上均具优势,其磷素积累优势主要体现在快增期和缓增期,这主要是由于在此两阶段较高的磷素积累速率和较长的积累时间。

Abstract:

【Objective】This study was conducted to quantitatively describe the dynamic changes of phosphorus accumulation of medium-maturity japonica/indica hybrids (MJIH) after transplanting based on simulation equations. 【Method】Yongyou 2640 and Yongyou 1640 were used as the test materials, and the japonica conventional rice (JC) cultivar Yangjing 4038 and Yangjing 4227, and indica hybrid rice (IH) Xinliangyou 6380 and Yangliangyou 6 were used as controls to study phosphorus accumulation characteristics after transplanting, and the differences in phosphorus uptake and utilization characteristics after transplanting among different rice types were compared. 【Result】Grain yield and total phosphorus accumulation at maturity of MJIH were both significantly higher than JC and IH. Compared with JC and IH, MJIH had higher grain phosphorus accumulation, while lower phosphorus grain productivity. MJIH showed lower phosphorus translocation from leaf after heading compared with JC and IH, and its phosphorus translocation from stem after heading fell in between. Gompertz equation was used to simulate phosphorus accumulation after transplanting of MJIH, while logistic equations for JC and IH. MJIH showed higher maximum nitrogen accumulation rate than JC and IH. The maximum phosphorus accumulation rate of MJIH was observed at 50–52 d after transplanting, 59–60 d after transplanting for JC, and 61–63 d for IH, respectively. Compared with JC and IH, MJIH had higher phosphorus accumulation at the middle and late stages, while lower phosphorus accumulation at the early stage. The higher phosphorus accumulation at the middle and late stages of MJIH was attributed to its longer duration and higher accumulation rate, relative to JC and IH. 【Conclusion】Our results indicated that compared with JC and IH, MJIH had superior grain yield and total phosphorus accumulation. The advantage in phosphorus accumulation of MIJH over JC and IH was seen at the middle and late stages, mainly owing to its longer duration and higher accumulation rate.
