| 摘 要： | 通过早、晚造田间试验,在桂林稻作区开展了水稻控释肥应用研究。结果表明,每公顷水稻控释肥用量早稻以636 kg为宜,稻谷产量比控释肥561、711 kg处理及常规施肥处理分别提高18.7%、15.1%和9.5%;晚稻则以773 kg为宜,稻谷产量比控释肥698、848 kg处理和常规施肥处理分别提高14.8%、7.5%和8.9%。

| Abstract: | Field trials were conducted with early and late rice to search for suitable methods for applying a rice-specific controlled-release fertilizer.Results illustrated that rational rate for the controlled-release fertilizer should be 636 kg/hm2 for early rice,which increased yield by 18.7%,15.1% and 9.5%,respectively over treatments of 561 kg/ hm2,711kg/hm2 of the controlled-release fertilizer,and local normal fertilization.For late rice,however,rational rate for the controlled-release fertilizer should be 773 kg/hm2,which increased yield by 14.8%,7.5% and 8.9%,respectively over treatments of 698 kg/hm2,848 kg/hm2 of the controlled-release fertilizer,and local normal fertilization. |
