摘要:
[目的]研究邯东599在冀南地区的适宜种植密度.[方法]在冀南地区中等肥力地块,以高产耐密型夏玉米邯东599为试验材料,采取随机区组试验设计,设5个种植密度处理,对比不同种植密度条件下玉米的主要农艺性状和产量性状.[结果]邯东599在冀南地区适宜种植密度为7.20万株/hm2,在该密度下玉米产量高而且经济性状好.[结论]该研究可为提高邯东599产量和种植效益提供技术支持.
Abstract:
[Objective] The suitable planting density of Handan East 599 in Southern Hebei was studied.[ Method] In the area of medium fertility plots, with high-yielding and density-resistant summer maize Handan East 599 as test material, we adopted randomized block design,set up 5 treatments to compare main agronomic traits and yield traits of maize under different planting density conditions.[Result]The suitable planting density of Handan East 599 in Southern Hebei was 72000 plants /hm2 , the yield was high and the economic character was good in this density. [Conclusion]The study can provide technical support for improving the yield and planting benefit of Handan East 599.
