采用同质性测验和方差分析方法 ,对晋西坝地玉米不同种植密度的试验资料进行综合分析 ,结果认为 ,在当地一般施肥水平的干旱年份 ,坝地玉米的最佳种植密度为 45 0 0 0株 /hm2 ～ 5 2 5 0 0株 /hm2 ,而 5 2 5 0 0株 /hm2 较 45 0 0 0株 /hm2在年际间表现更为稳定。
The results of homogeneity test and analysis of variance (ANOVA) showed that the best planting density of maize in dam area was 45 0 0 in the drought years of general fertilization level 0 / hm2-52500 / hm2, while 52 5200 / hm2 was more stable than 45 000 0 / hm2 over the inter-annual period.
