- ?为探索菜用大豆秋季延后栽培的适宜播期及品种,以衢鲜1号、衢鲜2号、六月半和衢鲜5号4个品种为材料,研究了秋季延后播种对菜用大豆鲜荚产量和主要农艺性状的影响。结果表明:供试材料的鲜荚产量随播期的延后而显著减少,衢鲜1号产量最高;株高、有效分枝数和每荚粒数随播期延后呈下降趋势;生育日数随播期延后出现先缩短后增长的趋势。综合考虑鲜荚产量和主要经济性状,衢州秋季菜用大豆播种日期不宜迟于8月25日,衢鲜1号较适合延后播种。

?Four autumn vegetable soybean varieties were planted to investigate the effects of delayed sowing on fresh pod yield and main agronomic traits in Quzhou,Zhejiang province for the purpose of exploring the suitable delayed sowing date and varieties.The results showed that as the sowing date delayed,the fresh pod yield,plant height,effective branches and seeds per pod of these varieties were reduced.But the growth period shortened first and then gradually prolonged with the sowing date delayed.Among those four varieties,Quxian 1 had the highest yield.Based on the fresh pod yield and main agronomic traits,the deadline for sowing date was August 25th in Quzhou,and Quxian 1 was suitable for late sowing.
