摘要
试验应用植物生长分析技术对具有不同熟期的春大豆品种进行了研究。结果表明，生育期的主要差异在初花后的生殖生长期，现蕾时，相对迟熟类型具有较大的叶面积指数（ＬＡＩ），叶重比（ＬＷＲ）和较小的比叶面积（ＳＬＡ），而始熟期（Ｒ７）则相反。在生育前中期，相对迟熟品种具较大的叶和地上部干重，产量亦以生育期较长的品种为高。试验还对各生育期的氮和钾含量进行了分析。
Study on spring soybean with various ripening dates using growth analysis technology was conducted in this experiment. The results showed that growth period difference in each soybean existed in the length of reproductive growth period after flowering. The leaf area index (LAI) and leaf weight ratio (LWR) were larger and specific leaf area (SLA) was smaller in relatively late ripening soybean during budding stage while it was opposite in ripening early stage (R 7). There was a larger leaf and shoot dry weight of relatively late ripening soybean in early and medium stages. The relatively medium and late ripening soybean had a high yield. The N and K content in main growth stages were also been analysed, respectively.
