| 摘 要： | 为探讨高油大豆的高产优质栽培技术,以高油大豆淮豆8号为材料,研究了播期和密度两因子对其产量及品质性状影响。结果表明:①A3B4(播期6月20日、密度30×104株/hm2)是适宜的播期和种植密度处理,籽粒产量达到3103.75kg/hm2;②播期对大豆产量与品质影响大于密度;③随着播期的推迟,单株荚粒数呈下降趋势,随着密度的增加,单株荚粒数由多到少,百粒重与播期关系密切。

| Abstract: | The study is to provide scientific basis for high production and quality of high-oil soybean with certain cultural factors.The field experiment was conducted to evaluate the effect of sowing stage and planting density on the seed yield and quality characteristics of high-oil soybean Huaidou 8.The results showed as follows: i The highest yield, 3103.75kg/hm2, in this experiment appeared in treatment with sowing stage at June 20 and with density of 30×104 plants per hectare. ii Sowing stage was more important for seed yield and quality than plant density. iii The pod-seeds per plant decreased as sowing stage delayed and as planting density increased.There was close relationship between l00-seed weight, seeds per pod and sowing stages, the l00-seed weight decreased when sowing stage after June 20. |
