| 摘 要： | 将来自北纬22.7°至北纬50.2°的19个春播大豆品种在2 a内分4期进行播种,研究了播期对不同生育期类型春大豆的形态和产量等生态性状的影响.结果表明:株高和主茎节数随着播期的延迟逐渐降低,并且降低幅度随着播期的延迟而增加.在各种熟期类型品种中,中早熟类型品种的株高和主茎节数降低的幅度最大.不同播期下大豆植株的地上生...

| Abstract: | Ninteen spring soybean varieties spread from N 22.7°to N 50.2°were sowed on 4 dates in 2 years,respectively.The objective of present research is to study the effect of sowing dates on ecological traits of spring soybean.The results showed that plant heights and nods of main stem decreased as sowing date delayed and the degree of delayed amount increased gradually.Among all mature types,early-middle varieties showed the lowest plant height and nods of main stem.There were significant variations in aboveground biological weight,dry stem weight,pod shell weight,seed weight,among different maturity varieties.Effect of sowing date varied according to maturity types.Under delayed sowing date(sowing at June 11 and July 1) the ratio of seed to aboveground biological weight(economical coefficient) increased for early and middle verieties early.Number of pod per plant,number of seed per unite area and 100-seed weight were increased for ueltra-early varieties. |
