| 摘 要： | 以引进和本地23个品种为材料,研究了在沧州气候条件下,不同播期对大豆产量及主要农艺性状的影响.结果表明:推迟播种,缩短了始花期至生理成熟期的天数,从而缩短了各品种的生育期;晚播严重降低了各品种的株高和主茎节数;产量、单株粒数、百粒重与播期达到了显著负相关,所以夏大豆适时早播意义重大.

| Abstract: | The introduced and local 23 species were used to study the effect of sowing date on yield and agronomic characters in the climate condition of CangZhou.The results showed that the relation of yield,seeds number per plant,100-seed weight and sowing dates achieved a significant negative correlation.With the delayed sowing date,days of flowering to physiological maturity reduced,thus shortening the period of fertility of all varieties.Late sowing severely reduced plant height and number of nodes on the main st... |
