| 摘 要： | 对山东沿海地区6市29县1975~2010年的大豆品种、总产量和栽培面积进行调查和分析。结果表明,期间该地区大豆单产增加显著,栽培面积和总产量经历了先降低后增加再降低三个发展阶段,年际间的变幅大且整体表现出下降趋势。通过栽培品种统计发现,大豆大产量(总产量≥104t)栽培品种虽然数量较少,但其占总产量之比大,对推动山东省大豆产业发展以及丰富我国大豆种质资源具有重要的作用与意义。

| Abstract: | The cultivar , total yield and cultivated area of soybean from 1975 to 2010 were investigated and analyzed in 29 counties , belonging to 6 cities of Shandong coastal regions .The results showed that the soybean yield per unit significantly increased during this time , while the total yield and cultivated area de-creased firstly , then increased before a consistent decrease with high fluctuation between different years and a downtrend on the whole .Based on the analysis of soybean cultivars , the number of high-yield cultivar （ total yield≥10 4 t） was small , but the proportion in total yield was high , which played an important role in promo-ting the development of soybean industry in Shandong Province and enriching soybean germplasm resources in our country . |
