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%。
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/hm^2 for early rice, which increased yield by 18.7%, 15.1% and 9.5%, respectively over treatments of 561 kg/hm^2, 71 lkg/hm^2 of the controlled-release fertilizer, and local normal fertilization. For late rice, however, rational rate for the controlled-release fertilizer should be 773 kg/hm^2, which increased yield by 14.8%, 7.5% and 8.9%, respectively over treatments of 698 kg/hm^2, 848 kg/hm^2 of the controlled-release fertilizer, and local normal fertilization.
