摘  要：
在基础地力和施氮总量相同的条件下,氮肥基追不同分施比例对寒地粳稻产量及氮肥利用率的影响。以11叶品种空育131和12叶品种垦鉴稻6号为材料,设基肥、蘖肥、调节肥和穗肥9种施肥比例。表明:氮肥基追不同分施比例对各时期植株体内氮素积累量差异显著,其中成熟期氮素积累量与产量呈显著正相关,相关系数r=0.67-0.75*。氮肥基追不同分施比例对氮肥利用率和产量差异显著正相关,相关系数为r=0.63-0.68*。在基础地力和施氮总量相同的条件下,基肥、蘖肥、调节肥和穗肥的最佳分施比例为4:2:2:2和4:3:1:2,这种施肥比例下氮肥利用率和产量高。

摘  要：
The aim of this experiment was to discount fertilizing nitrogen in different proportion between basefertilizer and top dressing fertilizer affects yield and efficiency of nitrogen fertilizer utilization of Japonica ricein cold region at the same level of soil fertilizer content and the same amount of nitrogen fertilizer application.In this paper,we used two rice cultivars'Kongyu 131'and'Kenjiandao 6'.The results were as followed,atevery stage of rice plant growing,there is significantly different among the amount of nitrogen accumulation ofplant.In the maturity,the amount of nitrogen accumulation with yield was positive correlation(r=0.67-0.75*).Fertilizing nitrogen in different proportion between base fertilizer and top dressing fertilizer was positivecorrelation with yield(r=0.63-0.68*).When the nitrogen was fertilizer in the base fertilizer,tillering fertilizer,regulation fertilizer,panicle fertilize of 4:2:2:2,and 4:3:1:2,the efficiency of nitrogen fertilizer utilization andthe yield were respectively the highest.
