摘　　要：[目的]提高广西夏大豆生产水平,建立华夏6号大豆新品种配套高产栽培技术。[方法]2014年在广西桂林开展了密度及播期试验,从6月5日至8月25日,分9个播种期种植,在7月3日播种期设置了4个种植密度试验,以期明确华夏6号在桂北的最佳播种期和合理群体密度。[结果]不同播期对大豆的农艺性状和产量都有明显的影响,在6月中旬至7月上旬播种,大豆产量表现较好,为3 000kg/hm^2左右;7月上旬的种植密度在19.5万-22.5万株/hm^2的产量较高,为3 600 kg/hm^2左右。[结论]华夏6号在桂北的最佳播种期为6月中旬至7月中旬,合理群体密度在19.5万-22.5万株/hm^2左右。[ Objective ] The research aimed to improve production level of summer-sowing soybean and establish the high-yield cultivation technique of new summer-sowing soybean variety Huaxia 6 in Guangxi. [ Method ] In order to determine the best sowing time and rational population density of summer-sowing soybean variety Huaxia 6, it was planted at nine sowing times from June 5, 2014 to August 25, 2014, and planted at four planting densities on July 3 in Guilin, Guangxi. [ Result] Sowing time and different densities had significant effects on agro- nomic characters and yield of the soybean. Soybean production was better from June 15 to July 15, about 3 000 kg/hm^2. And the yields were higher at 195 000 - 225 000 plants/hm^2 on July 3, about 3 600 kg/hm^2. [ Conclusion] The optimal sowing time and rational population den- sity of Huaxia 6 were the mid-June to mid-July and about 195 000- 225 000 plants/hm^2 in Guangxi, respectively.
