为在水稻生产中合理使用氮、磷、钾肥，以适合寒地种植的11叶品种空育131为试材，采用“3414”随机区组设计，研究不同的氮、磷、钾配比对水稻生长发育及产量的影响。结果表明：处理6（N2 P2 K2）、处理10（N2 P2 K3）和处理11（N3 P2 K2）可较明显地增加水稻的茎数；合理配施可明显提高水稻的干物质积累，成熟期各处理组合以处理10（N2 P2 K3）总干重最多，比对照高12．2％；增施氮、磷、钾可增加水稻产量，其中处理11产量和效益最高，产量达10519．5 kg·hm-2；经回归分析优化出空育131最高产量为12555 kg·hm-2，相应的氮肥、磷肥和钾肥纯量为135．0，67．5和58．5 kg·hm-2。

In order to use nitrogen ,phosphorus and potassium fertilizer reasonably in rice production of cold are-a ,taking Kongyu 131 as test material ,using randomized block design ,the effects of different ratio of nitrogen , phosphorus and potassium on growth and yield of rice were studied .The results showed that treatment 6(N2P2 K2 ) ,treatment 10(N2 P2 K3 )and treatment 11(N3 P2 K2 )could increase the rice stem number obviously ;reasona-ble fertilization could increase the dry matter accumulation of rice significantly ,total dry weight of treatment 10 (N2 P2 K3 )was 12 .2% which was higher than the control in mature period ;the increasing of nitrogen ,phosphor-us and potassium could increase the yield of rice ,the yield and benefit of treatment 11 were maximum by 10 519 .5 kg·hm-2 ;the highest yield of Kongyu 131 was 12 555 kg·hm-2 by regression analysis ,corresponding nitrogenous ,phosphate and potash fertilizer scalar were 135 ,67 .5 and 58 .5 kg·hm-2 .
