摘要
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。
The effects of different plant densities and nitrogen fertilizing metheds on grain yield and nitrogen accurnulation in various growth stages of barley were studied in this exPeriment. It was shown that grain yield was the highest under plant density of 1.72 × 106plants/ha in area of Haining, Zhejiang, nitrogen content of plant organs and grain yield were obviously increased with the ratioc of nitrogen fertllizer applied at tiller and boting stagcs. In this paper that the suitable plant density and ratio of dressing nitrogen fertilization for local barley pnduction were discussed.
