摘  要：
[目的]探讨高蛋白夏大豆涡豆5号的适宜播期密度组合。[方法]以涡豆5号为供试材料,设4个播期,5个种植密度处理,研究了播期和种植密度对涡豆5号生长发育及产量的影响。[结果]随着播期的推迟,涡豆5号产量减小;而随着种植密度的加大产量呈现先增后减的趋势,种植密度对其单株荚数及产量的影响大于播期对单株荚数及产量的影响。在6月5日播种,种植密度为2.55×105株/hm2时,产量最高为3 173.7 kg/hm2。[结论]条件允许的情况下,涡豆5号应尽量早播,适宜播期为6月5～12日,最佳种植密度为2.25×105～2.55×105株/hm2。若迟播,应适应增加种植密度。

摘  要：
[Objective]The aim was to study the appropriate combination of sowing time and planting density of high-protein Summer Soybean Guodou5hao.[Method]as the test materials,four sowing time and five planting density were designed,the effects of sowing time and planting density on grawth and development and yield of Guodou5hao were studied.[Result]With the sowing time delaying,the yield of Guodou5hao was decreased,while with the planting density increasing,its yield increasea first and then reduced.The effects of planting density on their pods and yield of Guodou5hao were bigger than that of sowing time.When planting in 5th June and planting density was 2.55 × 105 plant/hm2,the yield was the highest of 3 173.7 kg/hm2.[Conclusion]Under the permitting conditions,Guodou5hao should be sowing early and the suitable sowing time is 5th12th June,the optimum planting density is 2.25 ×105~2.55 ×105 plant/hm2.If the sowing time is putting off,the planting density should be increasea.
