摘要
以辽00139-1、辽00128-1两个菜用大豆品系为试材,比较了菜用大豆春播与夏播的生育进程中各时期的生长动态、鲜荚产量构成因素及鲜荚产量。结果表明:夏播菜用大豆生长发育迅速,一般80 d左右即可采摘收获。从植株生长发育水平上分析:菜用大豆春播营养生长时期平均株高大于夏播菜用大豆;春播菜用大豆生育进程比夏播菜用大豆滞后。从产量性状分析:菜用大豆春播单株荚数多于夏播;春播与夏播百粒鲜重接近;百荚鲜重与品种有关;春播菜用大豆单株发育水平比夏播菜用大豆好,有效分枝数比夏播多。辽00139-1春播与夏播鲜荚产量分别为12510.5 kg.hm-2和5229.4 kg.hm-2;辽00128-1春播与夏播鲜荚产量分别为12282.1 kg.hm-2和6762.6 kg.hm-2。
Two vegetable soybean lines of Liao 00139- 1 and Liao 00128- 1 were planted in spring（ May 10） and summer （June 29） in 2007, and the agronomic traits of spring and summer planted vegetable soybean, including growth dynamic, fresh yield components and fresh yield were compared. Results showed that, summer planting vegetable soybean had short growth duration, generally about 80 days pods can be picked up. The average plant height of spring planting vegetable soybean was higher than that of summer planting during the nutrition growth period. Each growth period of spring planting vegetable soybean were relatively postponed than those of summer planting. Spring planting vegetable soybean had better yield performance for more effective branches and pods, while 100-fresh seed weight between the two planting season was the same. 100 fresh pod weight（Liao 00139-1 were 204.2 g and 234.1 g,Liao 00128-1 were 253.3 g and 231.9 g for spring and summer planting, separately）was related to the lines. The fresh pod yield of spring and summer planting vegetable soybean for Liao 00139-1 were 12510.5 kg·ha^-1and 5229.4 kg·ha^-1, for Liao 00128-1 were 12 282.1 kg·ha^-1 and 6 762.6 kg·ha^-1, separately.
