| 摘 要： | 笔者进行了不同播期对夏播大豆产量及农艺性状的影响试验,结果表明:1)参试品种的生育期随着播种日期的延迟而缩短,主要是生育后期缩短,生育前期/生育后期的比值随着播种日期的延迟而加大。2)开花数、结荚数和结荚率随着播种期的延迟而增加。3)不同播期大豆品种的农艺性状和产量性状间差异明显。4)北京地区夏播大豆最适播种期为6月22日左右。 |

| Abstract: | Influence of sowing time on the yield and agronomic characters of summer soybean were studied. The results are as follows: 1) Growth period of varieties of summer soybean shortened after the planting time extension, of which were mainly days of post fertility period. The ratio of days of prefertility period to days of post fertility period rose along with the planting time extension.2) The number of flowering, pod setting and percentage of pod setting increased along with planting time extension.3) Sowing time had a significant influence on agronomic characters and yield of summer soybeans.4) Optimum time of sowing of summer soybean is around June 22 in Beijing. |
| Keywords: | summer soybean sowing time agronomic characters yield |
