以山宁16号为试材，研究播期对其生育期、农艺性状及产量性状的影响。结果表明：随播期延迟其出苗至初花日数（生育前期日数）缩短，开花至生理成熟日数（生育后期日数）差异不大，生育期结构增大；晚播缩短大豆营养生长期，株高、底荚高和主茎节数均降低；随播期推迟该品种的单株荚数、单株粒数虽有增加，但单株粒重、百粒重降低较多，其影响大于单株荚数、单株粒数增加的影响；晚播不利于大豆的鼓粒及产量的积累。

The field experiments were conducted to study the effects of sowing date on growth period , ag-ronomic and yield traits of soybean cultivar Shanning 16 as material.The results were as follows:with the de-lay of sowing date , the days from seedling emergence to first blooming decreased , the days from blooming to mature changed fewer , and the structure of growth period increased .Delayed sowing decreased the vegetative growth period , plant height , bottom pod height and node numbers of main stem , and increased pod number per plant and grain number per plant .But the decrease of grain weight per plant and 100-grain weight affect-ed the yield more than that of the increase of pod number per plant and grain number per plant .Delayed so-wing was not benefit to seed filling and yield accumulation .
