摘　　要：[目的]探讨3种不同基因型鲜食玉米(Zea mays L.)品种在不同地区的适宜种植密度。[方法]3个玉米品种分别为高秆大穗型品种京科糯2000(北京市农林科学院玉米研究中心)、矮秆型品种都市丽人(海南绿川种苗有限公司)、半紧凑或紧凑型品种玉美头601(广西壮邦种业有限公司)。种植密度分别为4.2万、4.8万、5.4万、6.0万、6.6万株/hm2。[结果]京科糯2000、都市丽人、玉美头601这3种类型玉米品种在不同地区的最佳种植密度不尽相同。对于高秆大穗型品种京科糯2000,在合浦栽培时最佳种植密度为6.0万株/hm2,在玉林栽培时最佳种植密度为4.8万株/hm2,在崇左栽培时最佳种植密度为6.0万株/hm2。对于矮秆型品种都市丽人,在合浦栽培时最佳种植密度为4.8万株/hm2,在玉林栽培时最佳种植密度为6.0万株/hm2,在崇左栽培时最佳种植密度为6.6万株/hm2。对于半紧凑或紧凑型品种玉美头601,在合浦栽培时最佳种植密度为6.6万株/hm2,在玉林栽培时最佳种植密度为5.4万株/hm2,在崇左栽培时最佳种植密度为6.0万株/hm2。[结论]该研究可为鲜食糯玉米的高产优质栽培提供参考。[ Objective] The aim was to discuss the suitable planting density of three genotypes maize varieties for fresh in different areas. [ Method] Three maize varieties were Jingkenuo 2000 of high stalk and large panicle type variety bred by Maize Research Center, Beijing A- cademy of Agricultural and Forestry Sciences, Doushiliren of short stalk type variety bred by Lvchuan Seed Co. , Ltd. of Hainan, and Yumeitou 601 of semi-compact type or compact type variety bred by Zhuangbang Seed Co. , Ltd. of Guangxi, resp.. The planting density were 4.2 x t04, 4.8 x 104, 5.4 x 104, 6.0 x 104, 6.6 x 104 plants per hectare, resp.. [ Result~ The optimum planting density of three genotypes maize varieties was different in different areas. For high stalk and large panicle type variety Jingkenuo 2000, the optimum planting density was 6.0 ~ 104 plants per hectare in Hepu, and was 4, 8 ~ 104 plants per hectare in Yulin, and was 6.0 x 104 plants per hectare in Chongzuo. For short stalk type variety Doushiliren, the optimum planting density was 4.8 x 104 plants per hectare in Hepu, and was 6.0 x 104 plants per hec- tare in Yulin, and was 6.6 ~ 104 plants per hectare in Chongzuo. For semi-compact type or compact type variety Yumeitou 601, the optimum planting density was 6.6 ~ 104 plants per hectare in Hepu, and was 5.4 ~ 104 plants per hectare in Yulin, and was 6.0 x 104 plants per hec- tare in Chon^zuo. [ Conclusion] The study provides a reference for high yield and ~ood ~ualitv cultivation of fresh edible waxy maize varieties.
