摘　　要：在处于华南热带四季大豆区的广州进行露地周年 (每批间隔 7- 10天 )连续播种菜用大豆 ,试验表明 :在≥ 10℃的有效积温超过 16 0 0℃、有效光照时数高于 2 80小时均可播种 ,植株生长正常 ,田间播期以 3月中至 9月底为好。其中春播至收获R6 -R7青荚需 70天左右 ,株产、品质和售价较高 ;夏播至收获青荚需 6 0天左右 ,株产 .品质和售价较低 ;秋播至收获青荚需 75天左右 ,株产、品质和售价最高。Vegetable soybeans were seeded in whole year in Guangzhou which is in tropical and subtropical zones, the results showed that the soybean plants grew normally in such environment as the effective accumulated temperature is≥1600℃ and the effective illuminated time is above 280hrs. It was properly that the soybeans was seeded from the dates of the lot 10 t h-20 t h of March to September. If the soybean was seeded in spring, about seventy days were needed from seeding to harvest the pods which is in R 6-R 7, and only sixty days were needed if the soybean was seeded in summer, but seventy-five days were needed if the soybean was seeded in autumn. The yield, the quality and the benefit of the soybeans seeded in autumn were the best among those of the soybeans seeded in the three seasons.
