摘要
本文采用复裂区设计法研究了品种、肥力和播期效应,结果表明,三因素对产量的效应的大小顺序依次为品种>播期>肥力。品种以晋春9号产量最高;随播期的推迟,公顷产量、有效穗数和千粒重降低;随施磷量的增加,公顷产量、有效穗数和千粒重增加,穗粒数相对稳定;品种、肥力和播期间无特异相互作用。
The split-split plot design was used to study the affects of variety, soil fertility and sowing time on yield and its components of spring wheat in this paper. It was indicated that the order of three factors on yield of spring wheat was Variety>Sowing time>soil fertility. Among three varieties,' Jin chun NO9″ spring wheat had the highest yield. The yield and available ears of per hectare and 1000—kernel grain weight were belowed with the sowing time late, and the available ears of per hectare and 1000—kernel grain weight were increased with the ammount of phosphrous fertility increasing, but the grains of per ear was relative stable. No special interaction existed among variety, soil fertility and sowing time.
