摘　　要：本文以银杏种子为研究对象,研究不同的置放方式及覆膜处理对银杏种子发芽的影响,结果表明:在不同覆膜处理条件下,纵棱纵向垂直于地面置放方式的发芽率高于纵棱横向垂直于地面和纵棱水平于地面,且纵棱纵向垂直于地面置放方式较其他两种方式早3 d进入快速发芽期;全覆盖薄膜处理条件的发芽率明显高于未覆盖薄膜和半覆盖薄膜,表明采用全覆盖薄膜处理更加有利于银杏种子发芽。该结果可为银杏播种育苗提供参考。In this paper,Ginkgo biloba seeds were the study objects and a study was made on the effects of different placement methods and film treatments on the germination of G.biloba seeds.The results showed that under different film treatment conditions,the germination rate of the placement method with the longitudinal ridges perpendicular to the ground was higher than that of the longitudinal ridges perpendicular to the ground and the longitudinal ridges horizontal to the ground,and the placement method with the longitudinal ridges perpendicular to the ground entered the rapid germination period 3 days earlier than the other two methods;the germination rate of the full-cover film treatment condition was significantly higher than that of the uncovered film and half-covered film,indicating adopting the full-cover film treatment was more conducive to the germination of G.biloba seeds.The results could provide reference for seeding propagation of the species.
