Abstract

Key words: Fertilizer application, Grasses, Seed yield, Seed development, Physiological and biochemical characters

摘要： 选择不同种类的禾本科(Gramineae)牧草,在河北省张家口市塞北管理区(原名沽源牧场)“948”项目牧草种子田内,连续两年(2002-2003)施肥、疏枝、喷施叶面肥及抗倒伏剂,研究施肥对禾本科牧草种子产量形成及种子发育过程中生理生化变化的影响,结果表明: 禾本科牧草种子生产中,氮是限制扁穗冰草(Agropyron cristatum L.Gaertn.)种子产量的主要营养元素,其次是磷,再次是钾.
