摘  要：
以籼型单季超级杂交稻中浙优1号为材料,研究水稻强化栽培氮肥管理对产量与氮素利用率的影响。结果表明:水稻强化栽培与常规栽培对照比较,增产达11.1%-15.2%,氮肥回收率比对照高5.3%~26.9%,农学利用率比对照高67.2%~92.2%,生理利用率比对照高6.0%~80.5%。因此,在水稻生产上应用水稻强化栽培可以提高氮肥的利用,降低氮肥在环境中积累及对环境造成污染。此外,本文对水稻强化栽培下氮肥管理的高产机理进行了探讨。

摘  要：
The experiment of rice intensification system(SRI) was carried out using super hybrid rice(Zhongzheyou 1) as material to investigate the grain yield and nitrogen utilization under different nitrogen managements.The results showed: the grain yield of SRI was 11.1%-15.2% greater than that of CK,and the assimilation efficiency,agronomic efficiency,and physiological efficiency of nitrogen fertilizer were 5.3%-26.9%,67.2%-92.2%,and 6.0%-80.5% greater than those of CK,respectively.Hence,nitrogen utilization efficiency,and eliminated accumulation of N fertilizer and its impact on the environment were enhanced under the system of rice intensification.Moreover,the high-yield mechanism of N fertilizer management under the system of rice intensification was discussed in the paper.
