以水稻品种富源四号（96D-10）为试材，采用随机区组设计的方法，对水稻控释肥施用量及施用方法进行了研究。结果表明：处理3（N-P-K：24-14-8）937．7kg·hm-2（基施524．4kg·hm-2、4叶期追施413．3kg·hm-2）公顷保苗数和穗粒数分别较其它处理高5．7％～13．9％、6．5％～8．1％，空秕率较其它处理低5．3％～32．2％。不同施肥处理总茎数、收获穗数、穗长间存在显著差异。水稻全生育期施用缓控释肥（N—P-K：24—14—8）937．5kg·hm-。（基施525kg·hm-2、四叶期追施412．5kg·hm-2）产量最高，为11857．5kg·hm-2，施用控释肥较常规肥增产26．5％。

Taking rice variety Fuyuan No. 4 as material,the application of controlled releasing fertilizer and fertilizer method were studied by randomized block design. The result showed that the seedling number and grains per spike of treatment 3 were higher than the other treatments by 5.7%- 13.9%,6.50%-8. 1 %,sterile grain rate was lower than the other treatments by 5.3%- 32.2%. There was significant difference between total stems, harvest spikes and spike length of different treatments. The yield reached the highest with the application of releasing fertilizer （N-P-K： 24-14-8） 937.5 kg·hm-2 （basal application was 525 kg. hm-2 and tillering stage top dressing was 412. 5 kg·hm-2 ） during the whole growth period of rice, and the highest yield was 11 857.5 kg.hm-2. Application of controlled releasing fertilizer could increase yield by 26.5% compared to the traditional fertilizer.
