摘　　要：为探索大豆新品种黔豆8号的适宜播种期,在代表贵州省西南部大豆主产区的盘县对大豆新品种黔豆8号进行了7个不同播期处理试验。结果表明对各播种期对鲜食荚产量和干籽粒产量的影响差异达极显著,对生育性状影响显著,对形成产量的主要农艺性状(荚\粒等)影响较大。试验结果确定了黔豆8号在盘县作为900kg/667m2以上高产鲜食荚生产的播期为4月22日-5月2日,提早上市可于4月2日开始播种,明确了黔豆8号作为杆子粒生产达到220kg/667m2以上的播种时期为4月12日-4月22日。In order to explore appropriate sowing date of new soybean variety Qiandou 8, 7 different sowing dates were tested ;.n Panxian, a presentative county in south--west of Guizhou. The results showed that fresh yield and grain yield of soybean on different sowing dates were extremely significantly, the growth characteristics of soybean were significantly, it＇s influenced the main agronomic traits（legume/grains）. The sowing date were 22nd Apr to 2nd May, yield of soybean was able to over 900kg/ 667m2 in Panxian, if the fresh soybean was early sold in market, the appropriate sowing date was 2nd Apr. It＇s indicated that for aimed to realize the yield more than 220kg/667m2, the appropriate dowing date were 12th Apr to 22nd Apt in condition of Panxian.
