| 摘 要： | 施用缓控释肥是缓解我国水稻生产中施氮量高、氮肥利用率低的有效措施。本文总结了缓控释肥施用量和施用方式等对水稻产量和稻米品质的影响及机理。适量减氮施用缓控释肥可保证水稻产量并有效提高氮肥利用效率和改善稻米食味品质。改进施肥方式,如采用侧深施肥或配施速效氮肥有利于进一步提高水稻产量。未来应加强缓控释肥影响稻米品质形成的内在机理、缓控释肥稻田释放规律与水稻根系生长关系及缓控释肥两者混施对水稻产量和稻米品质影响等问题的研究,达到进一步增产增效。

| Abstract: | The application of slow/controlled release fertilizer (SCRF) is an effective measure to solve the problem of the high nitrogen application rate and low nitrogen use efficiency in rice production in China. This paper summarized the effects of application rates and methods of SCRF on grain yield and rice quality and their mechanisms. Appropriate nitrogen reduction of SCRF could still ensure rice yield and effectively improve nitrogen use efficiency and taste quality of rice. Improving fertilization methods, such as lateral deep fertilization or the combined application of conventional nitrogen fertilizer, could further increase the rice yield. In the future, further studies should focus on the effects and internal mechanisms of SCRF on grain quality, the relationship between the release curve of SCRF and the growth of rice roots and the effects of combined application of slow-release fertilizer and controlled-release fertilizer on grain yield and rice quality to further increase yield and utility. |
