为探明不同栽培方式下施用缓释肥对水稻生长及产量的影响，选取湖北省漳河灌区为研究区域，设置“移栽+常规肥”（F1N1）、“移栽+缓释肥”（F1N2）、“直播+常规肥”（F2N1）和“直播+缓释肥”（F2N2）4个处理，以水稻品种钻两优超占为试验材料开展小区试验。结果表明，F1N2处理对水稻株高促进作用最强，黄熟期可达127.6 cm，比F2N1处理高15.6 cm，且差异达极显著水平;F1N2处理对水稻分蘖促进作用极显著，每丛最多可达28.6个，而F2N2仅为11.7个;F1N2处理水稻产量为7 536 kg/hm²，比F2N2处理高13.3%，比F1N1、F2N1处理产量分别高出21.2%和28.2%。

In order to explore the effects of slow-release fertilizers on rice growth and yield under different cultivation methods, the Zhanghe Irrigation District in Hubei Province was selected as the research area, and four treatments including “transplanting + conventional fertilizer” （F1N1）, “transplanting + slow-release fertilizer”（F1N2）, “direct seeding + conventional fertilizer” （F2N1）and “direct seeding + slow-release fertilizer”（F2N2） were set up, and the plot experiment was carried out with rice variety Zhuanliangyou Chaozhan as the experimental material. The results showed that F1N2 treatment had the best effect on rice plant height, reaching 127.6 cm at the yellow maturity stage, which was 15.6 cm higher than the F2N1 treatment, and the difference reached a very significant level. F1N2 treatment had a very significant effect on rice tiller promotion, up to 28.6 per clumps, while F2N2 only 11.7. The rice yield of F1N2 treatment was 7 536 kg/hm², which was 13.3% higher than that of F2N2 treatment, and 21.2% and 28.2% higher than that of F1N1 and F2N1 treatments, respectively.
