摘　　要：通过花椰菜不同种植密度试验,采用灰色关联度分析方法,找出种植密度与各农艺性状的主次关系,以期探明花椰菜利卡1号在滇中高海拔冷凉山区反季节同等栽培条件下种植密度对产量及农艺性状的影响。结果表明,种植密度对花椰菜利卡1号各农艺性状重要性的排序为产量>开展度>生育期=外叶数>球纵径>球横径>单球重>株高。不同种植密度下花椰菜利卡1号各农艺性状综合表现排序为4.95万株/hm^2>4.50万株/hm^2>5.40万株/hm^2>4.05万株/hm^2>3.60万株/hm^2>3.15万株/hm^2>5.85万株/hm^2。Through the experiment of different planting densities of cauliflower and the method of grey correlation analysis,this paper tried to find out the primary and secondary relationship between planting density and each agronomic character,in order to find out the influence of planting density on yield and agronomic character of Lika 1.The results showed that the order of the importance of planting density on each agronomic character of Lika 1 was yield>development degree>growth period=number of outer leaves>vertical diameter of ball>horizontal diameter of ball>weight of single ball>plant height.Under different planting densities,the comprehensive performance order of each agronomic character of Lika 1 was 49500 plants/hm^2>45000 plants/hm^2>54000 plants/hm^2>40500 plants/hm^2>36000 plants/hm^2>31500 plants/hm^2>58500 plants/hm^2.
