| 摘 要： | 哈尔滨条件下错期播种三份大兴安岭农区的极早熟大豆，结果表明，播期对极早熟大豆的产量具有显著影响。哈尔滨条件下种植85－100天的早熟大豆，在5月15日－5月30日之间播种均可获较高的干物质重和子实产量。播期对早熟大豆的许多农艺性状具有大的影响。无论在何时播种早熟大豆，干物质重总是一个与产量密切相关的重要性状，而瘪粒率是降低产量的主要原因。 |
| 关 键 词： | 极早熟大豆 播期 产量 干物质重 农艺性状 |

| Abstract: | Effect of planting time on yield and agronomic characters of 3 extremely early soybean verities was studied in Harbin. The results showed that planting time had a tremendous influence on the yields of early soybean varieties. The higher dry matter weight and seed yield could be obtained in Harbin if soybean varieties with 85-100 growth period were planted between May 15 and May 30. Planting time had a significant influence on many agronomic characters of extremely early soybean varieties. The dry matter weight was always an important character for yield of early variety under any planting time. And the percentage of shriveled seeds was the major factor for decreasing yield. |
| Keywords: | Early soybean Planting stage Yield Dry matter weight |
