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/hm2 4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/hm2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.
Abstract
[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.
