摘　　要：[目的]研究氮素调控对寒地水稻生物性状和产量的影响。[方法]利用大区对比的方法研究新型氮素调控技术对水稻生长发育和产量的影响。[结果]结果表明,优化施肥(INM)处理比农民习惯施肥(FFP)处理株高高,分蘖多。INM处理水稻鞘腐病和褐变粒均比FFP处理轻,鞘腐病发病率和病情指数分别比FFP低13.1%和14.3%;褐变粒发病率和病情指数分别低8.8%和3.3%。INM处理平方米有效穗、穗粒数、穗实粒数、千粒重和产量均比FFP处理高,空瘪率比FFP低1.3%;有效穗多23.8穗/m2、穗实粒数多2.3粒,产量达9.27t/hm2,比FFP增产7.0%。[结论]该研究结果为寒地水稻的高产优质生产提供理论指导。[ Objective] The purpose of this research was to study the effect of nitrogen control on growth and output of paddy rice. [ Method] The contrast method was used in fieM to study the effect of nitrogen control on growth and output of paddy rice. [ Result ] The results showed that the height of paddy rice with INM treatment was mere than FFP, the ronen disease of vagina and brown granule of INM was lighter than FFP. The effective ear number, seed granule number, 1 000-grain weight of seeds and output of paddy rice with INM treatment was more than INM, the empty seeds rates of FFP was lower than FFP, the output reached 9.27 t/hm^2, increasing the production by 7.0% than FFP. [Conclusion]This research will provide the theoretical direction for high yield and quality production of paddy rice.
