摘　　要：[目的]筛选适宜糯玉米种植的密度。[方法]选用金糯628作试验材料,设置37 500、45 000、52 500、60 000株/hm^24个处理,分析糯玉米的穗部性状、农艺性状。[结果]种植密度影响糯玉米的穗长、果穗率、经济效益等,种植密度在52 500株/hm^2时,合格果穗率、一级果穗率较高,经济效益高。[结论]在糯玉米的种植过程中,应采用合理的种植密度,以提高经济效益。[ Objective ] The objective of this study is to screen suitable planting density for waxy corn. [ Method ] Selecting Jinnuo 628 as test material, four planting density treatments of 37 500,45 000,52 500,60 000 plants per hectare were set to analyze ear characters and agronomic characters of waxy corn. [ Result ] Planting density affected ear length, fruit cluster rate, economic benefit and so on. When planting density was 52 500 plants per hectare,the effective fruit cluster rate, first-level fruit cluster rate were higher, economic benefit was high. [ Conclusion ] In the planting process of waxy corn,suitable planting density should be adopted to improve economic benefit.
