摘要: 以香樟(Cinnamomum camphora)扦插苗为研究对象,研究了3种不同栽培基质对扦插苗叶片、根系及植株生长的影响。结果表明,不同栽培基质对扦插苗生长指标的影响各不相同,珍珠岩对扦插苗的单叶叶片和根系生长有较好地促进作用,且成活率更高,达到38.4%,显著高于砻糠灰和复合土,但砻糠灰对扦插苗的全株叶面积、全株叶鲜重以及苗高、地径有更好地促进作用。因此,认为不同基质对扦插苗地上部分和地下部分生长的促进作用不同。Abstract: Taking one-year-old Cinnamomum camphora cutting seedlings for the object, studies were made of the effects of three different mediums on the growth of leaves, roots and plants of the cutting seedlings.The results showed that the influence of different growing mediums on the cutting seedling growth index were various.And perlite was benifitcial to the single leaf and root growth of cutting seedlings and the survival rate was the highest, reaching 38.4%, which was significantly higher than the compound soil and rice chaff ash.However, rice chaff ash was conducive to the leaf area and leaf fresh weight of the whole plant and the height and ground diameter of the cutting seedlings.So different growth mediums played varied different roles in the growth of aboveground and underground parts of the cutting seedlings.
