Shuitu Baochi Xuebao, 2004 对小麦氮素营养与籽粒灌浆期氮素转移研究进展进行了综述。过去进行的大量研究结果表明,小麦籽粒最终累积的氮素有相当一部分来自于灌浆期间营养器官中氮素的再转移,来自营养器官氮(内源氮)与土壤中新吸收氮(外源氮)的比例基本上是1:2。因此,花后营养器官氮素营养水平是决定小麦籽粒产量、籽粒中氮素累积量和蛋白质含量的一个重要因素。灌浆期间营养器官氮素向籽粒发生转移的同时,常常伴随着叶片光合性能的下降和叶片的衰老。不同基因型品种在灌浆期的氮素转移程度不同,表现为随品种演替,旗叶、茎秆和叶鞘中氮素的输出率增加 ...

Shuitu Baochi Xuebao, 2007 在大田条件下,研究了不同施硫水平对不同筋力类型品种植株C-N积累与转运规律和籽粒产量及蛋白质、淀粉含量的影响.结果表明,施硫处理提高了两品种成熟期单茎籽粒重和籽粒氮素的积累量和开花前营养器官贮存干物质和氮素的转运量以及转运干物质和氮素对籽粒重和籽粒氮素积累的贡献率,与不施硫对照(S0)相比,每1 hm2施20 kg纯S(S1)处理能明显提高两品种的产量构成因素,显著提高籽粒产量,两品种分别增产10.69%和9.78%,同时极显著地提高了籽粒蛋白质和淀粉含量.大量施用硫肥(100 kg/hm2 ...
