| 摘 要： | 以龙麦26为材料,研究了不同播种期对强筋小麦植株形态建成和产量构成的影响,结果表明:晚播不利于植株茎叶的生长,株高降低,叶面积减小,叶绿素含量降低;晚播使得营养生长缩短,减少了植株地上部干积累的物质量,但后期茎叶营养物质的输出加快;晚播不利于小穗的形成,但有利于分蘖的发育。在试验地生态条件下,晚播使得产量下降。

| Abstract: | Taking Long-Mai 26 as the material, the effects of different sowing date on the morphological characters and yield component characters were studied. The results showed that late sowing accumulation might be disadvantageous to the growth of stem and leaf, might reduce the height of plant, leaf area and the chlorophyll content, shorten the nutritious growth, and reduce the dry matter accumulation of overground plant, but speed up the nutrients output of the stem and leaf in the later growth stage further more. Late sowing accumulation might be disadvantageous to spikelet formation, but be advantageous to the growth of tiller. Under the local ecological condition of experimental plot, late sowing accumulation reduced grain yield. |
