将天津市区绿化用土和武清区农用土分别掺以不同比例的沙子,改变其物理结构,在实验室条件下通过栽培试验.研究分析不同土壤结构对沙冬青(Ammopiptanthus mongolicus)幼苗生长发育的影响.结果表明.市区绿化用土在土:沙为3:1时,沙冬青幼苗生长发育情况最佳.
Under the condition of the laboratory by growing experiment, the effect of different soil structure on seeding of Ammopiptanthus mongolicus were investigated by mixing sand of different proportion into soil used for virescence of Tianjin cantonal and Wuqing field to change the structure of the soil. The results showed that A. mongolicus grow best when the proportioning of soil and sand is 3 : 1.
