摘　　要：本文针对花生在新疆地区特殊生态条件下不同播种期对其生长发育及其产量性状进行研究。结果表明,随着播期推迟,花生播种-花针期日数减少、全生育期明显缩短;5月7日之前播种的花生LAI波动较大,LAI峰值明显高于5月12日以后播种;叶绿素含量峰值出现较早,峰值时晚播处理叶绿素含量高于早播,而且播期较早处理的叶绿素含量下降快;群体生长率和光合势指标均以5月7日播期较高,其百果重、百仁重、荚果产量和含油量均显著高于其他处理。In this paper, the development and yield characters of peanut with different sowing date under special ecological conditions of Xinjiang were studied. The results showed that, with the delay of sowing date, the period from sowing to flowering stage was shortened, resulting in an evident shortening of the whole growth period. Before 7^th May, the earlier the sowing date, the larger fluctu- ant the leaf area index （LAI） was. The peak of LAI of that sown before 7th May was higher than that sown after 12^th May. Ahead of time the peak of chlorophyll content was, the later the sowing, the higher the chlorophyll content was, and the earlier the sowing, the faster the decline of chlorophyll content. In respect of population growth rate and leaf area duration of that sown on 7^th May are higher than other treatment. So were the 100-pods weight, 100- seeds weight, pod yield and oil content.
