摘　　要：播期和密度两因子对楚秀鲜荚产量及荚粒性状影响的研究结果表明:①A3B3(播期6月25日、密度24×104株/hm2)是适宜的播期和种植密度处理,鲜荚产量达到9050.0kg/hm2;②播期对菜用大豆鲜荚产量影响大于密度;③随着播期的推迟,单株荚数先增后减,随着密度的增加,单株荚数由多到少,百荚鲜重与播期关系密切;④根据品种的特点探讨了楚秀的高产原因。The field experimment was conducted to evaluate the effect of sowing dates and planting density on the fresh pod yield and pod-seed characteristics of vegetable soybean cultivar Chuxiu. The results showed as follows, i The highest yield in this experiment appeared in treatment with sowing date at June 25 and with density of 24× 10^4 plants per hectare,its fresh pod yield could be 9050kg/hm. ii Sowing date was more important for {resh pods yield than plant density , iii The pods per plant increased and then decreased as sowing stage delayed and pods per plant decreased as planting density increased. There was close relationship between fresh 100-pod weight and sowing dates, iv The reason of high yielding of Chuxiu have been discussed based on charaeteristics of the cultivar.
