摘要
在青海大学农林系实验田采用单因素设计,以小麦、油菜叶片、蚕豆叶片淋洗液分别浇灌盆栽秦艽幼苗作为处理,以清水浇灌盆栽秦艽幼苗为对照,进行不同农作物处理秦艽幼苗的试验,结果表明:三种不同农作物叶片淋洗液对秦艽幼苗的主茎叶片数、分枝数没有促进或抑制作用,油菜、蚕豆叶片淋洗液抑制了秦艽幼苗叶片叶绿素含量的增加,同时,也抑制了秦艽根干重、根粗、根长的增加。油菜叶片淋洗液对秦艽幼苗生长的抑制作用比较强,蚕豆的比较弱。
The effect of different crop leaves eluent on the growth of Gentiana macrophylla seedling was made in the field. watering Gentiana macrophylla seedlings with wheat、rape and broad bean leaves eluent.The results shows that the three leaves eluent have no improvement on the main stem leaf number and branch number of Gentiana macrophylla seedling. The leaves eluent of rape and broad bean hinders the increased of chlorophyll content,root dry weight and root length. Rape leaves eluent has stronger inhibitory effect than bean leaves eluent on Gentiana macrophylla seedling.
