以空育131和垦鉴稻6号为材料，设置3种氮肥施用量（300 kg·hm-2、350 kg·hm-2、375 kg·hm-2），研究氮肥用量对寒地水稻植株形态特征和产量形成因子的影响，以探明不同氮肥用量对水稻生长和产量的影响，并提出最佳的施肥量。结果表明：应用垦鉴稻6号和空育131，氮肥施入量为350 kg·hm-2的处理产量均最高，并且对每穴穗数有显著提高，对每穗着粒数（垦鉴稻6号）、千粒重（空育131）提高效果较好。此外，氮肥施入量为350 kg·hm-2的处理可明显增加LAI、上三叶LAI、上四叶LAI和每穴穗数，且应用空育131品种的产量与LAI、上三叶LAI、上四叶LAI呈极显著正相关，应用垦鉴稻6号的产量与每穴穗数呈极显著正相关，与着粒数、千粒重和穗长呈显著正相关。试验条件下，总施氮量350 kg·hm-2，是水稻实现高产的理想施肥量。

Effects of fertilization application amount on rice morphological characteristics and grain yield components were studied with Kongyu 131 and Kenjiandao 6 as material in cold area.3 nitrogen application amount(300 kg·hm-2,350 kg·hm-2,375 kg·hm-2) were designed. The results showed that the production were the highest in the treatments which nitrogen application amount were 350 kg·hm-2 by using Kongyu 131 and Kenjiandao 6,and had significantly improved in the panicles per plant,and the effects were better to improve the grain number per panicle (Kenjiandao 6)and 1 000 mix grain weight (Kongyu 131). The treatment that nitrogen application amount were 350 kg·hm-2 could improve LAI,LAI of top-three leaves,LAI of top-four leaves and the panicles per plant obviously. In Kongyu 131,grain yield was positively correlated with LAI,LAI of top-three leaves and LAI of top-four leaves. In Kenjiandao 6,grain yield was positively correlated with the panicles per plant,and was positively correlated with the grain number per panicle,1 000 mix grain weight and panicle length .Under this experiment condition,the total nitrogen fertilizer application of 350 kg·hm-2 were more rational.
