本试验研究了密度及氮肥运筹对大麦籽粒产量和氮积0累的影响。结果表明，在本地区以基本苗为172万／hm2的群体籽粒产量最高，增加壮蘖肥和穗肥比例可明显提高植株器官氮含量和籽粒产量。明确了生产上宜采用的基本苗密度和氮肥运筹比例。
In this study, the effects of density and nitrogen fertilizer application on grain yield and N accumulation in barley were studied. The results showed that the population with the basic seedlings of 1.72 million / hm2 in this area had the highest grain yield. Increasing the ratio of sturdy and tillering fertilizer to panicle fertilizer could obviously increase the nitrogen content and grain yield of plant organs. Clear the production should adopt the basic seedling density and nitrogen fertilizer operation ratio.
