摘　　要：利用方差分析和相关分析方法研究种植密度对春小麦品种青麦10号产量及产量构成因素的影响,以确定其在青海春麦主产区适宜的种植密度。结果表明,种植密度对青麦10号各农艺性状的影响显著,综合各群体性状指标,以中密度处理(675万粒/hm2)可以获得较高产量。Variance analysis and correlation analysis were used to study the effect of planting density on yield and yield components of spring wheat Qingmai 10,so as to determine the suitable planting density in the main production area of spring wheat in Qinghai Province.The results showed that planting density had significant effect on the agronomic characters of Qingmai 10,and the medium density treatment(6.75 million grains per hectare)could obtain higher yield.
