| 摘 要： | 以生长2年和生长3年老芒麦为试验材料,研究收获时间对其种子产量的影响。结果表明,随着老芒麦种子的成熟,收获的种子产量逐渐增加,在盛花期后26-27d收获可以获得较高的种子产量,延迟收获种子产量则呈下降趋势。生长3年老芒麦同生长2年老芒麦相比,其种子产量下降50%左右。

| Abstract: | The experiments were conducted at Yuershan farm,Chengde Hebei Province,to study how harvest time affects the amount of seed yield of Siberian wildrye(Elymus sibiricus L.) growing two and three years.The results shows that 26-27 days after the peak anthesis is the best time for harvesting the seed.Any delay would cutail the yield.Seed yield of three-year-old Siberian wildrye is only fifty percent of that of the two-year-old. |
