为探讨‘桂夏豆2号’的适宜播期，试验设8个处理，研究播期对‘桂夏豆2号’农艺性状及产量的影响。结果表明：不同播期的‘桂夏豆2号’产量及农艺性状差异明显，随着播期的推迟，‘桂夏豆2号’产量减少。在6月上旬至7月下旬期间早播有利高产，8月上中旬播种产量低。因此，在适宜的播种期内早播有利于提高产量。

For the purpose of the optimum dates, set eight treatments and researched on the effect of different sowing dates on soybean yield and agronomic characters of ‘Guixiadou No.2’ in northwest Fujian Province. The results showed that different sowing dates had great effects on yield and agronomic characters. And earlier planting within the first ten days in June to the last ten days in July was good for higher yield, and the yield with the sowing date of the former twenty days in August was lower. Therefore, in the appropriate sowing, early sowing help to improve yield.
