| 摘 要： | 在大田栽培条件下,以汕优 63为对照,分析了不同施纯氮量( 0 kg/hm2、150.0 kg/hm2、187.5 kg/hm2、225.0 kg/hm2、262.5 kg/hm2)对扬两优 6号产量及其对氮素吸收利用特性的影响.结果表明:扬两优6号吸氮量、干物质积累量随施氮量的增加而增加;籽粒产量和氮素利用率以施纯氮225.0 kg/hm2处理最高.在相同施氮水平下,扬两优6号的籽粒产量、吸氮量、干物质积累量以及氮素利用率和产谷效益均高于汕优 63.

| Abstract: | Rice cultivar Shanyou 63 was used as check variety to study the effects of different nitrogen fertilizer levels(0 kg/hm2,150.0 kg/hm2,187.5 kg/hm2,225.0 kg/hm2,262.5 kg/hm2) on yield and N uptake of Yangliangyou 6,a hybrid indica rice variety,under paddy cultivation.The amount of N uptake and accumulation rate of dry matter were increased with the N application level.The yield and N utilization rate were elevated with N application level at first,amounted to the greatest value at moderate N level(225.0 kg/hm2).The yield,amount of N uptake,accumulation rate of dry matter,N utilization rate and N efficiency in producing grain of Yangliangyou 6 were higher than those of Shanyou 63 at the same N leve1. |
