摘 要： 以閩楠（Phoebe bournei）幼苗為研究對象，將其幼苗作三種不同處理后裸根移栽到試驗苗圃，其中處理一為幼苗根部浸泡在由水、土、ABT生根粉、保水劑及粘合劑配成的泥漿水中30 min；處理二為幼苗根部浸泡在由水、土、保水劑和粘合劑配成的泥漿水中30 min；處理三對照組為幼苗根部浸泡在由水、土配成的泥漿水中30 min。定植養(yǎng)護三個月后統(tǒng)計成活率、測量植株株高、胸徑，并取其新生葉片，檢測水分、葉綠素、可溶性糖、可溶性蛋白質(zhì)含量指標。結(jié)果表明：閩楠幼苗根部經(jīng)在由水、土、ABT生根粉、保水劑及粘合劑配成的泥漿水中浸泡30 min后，移栽成活率最高，同時這種移栽苗相比其他兩種處理，苗木相對長勢快，葉片中光合色素含量高，可溶性糖含量高，蛋白質(zhì)含量高，是較適合生產(chǎn)上規(guī)模化應用的方法。

關鍵詞： 閩楠；裸根移栽；葉綠素；可溶性糖

Abstract： Phoebe bournei seedlings were used as the research object， and the seedlings were transplanted into the experimental nursery by three different treatments. The root of the seedlings was soaked in water， soil， ABT rooting powder， water retaining agent and stick The mixture was treated with water， soil， water retaining agent and binder in the mud water for 30min. The three control groups were treated with the root of the seedlings soaked in water and soil. Mud water for 30min. The survival rate of the plants was measured after three months of planting and control. The plant height and DBH were measured， and the fresh leaves were taken to measure the water， chlorophyll， soluble sugar and soluble protein content. The results showed that the roots of Phoebe bournei were treated with water， soil， ABT rooting powder， water retaining agent and binder in the mud water for 30min， and the transplanting survival rate was the highest. At the same time， Treatment， seedling relative growth is fast， leaves in the light and high pigment content， high soluble sugar content， high protein content， is the most suitable for large-scale production of the application method.

Key words： Phoebe bournei；bare root transplanting；chlorophyll；soluble sugar

閩楠隸屬于樟科（Lauraceae）楠屬（Phoebe），常綠闊葉樹種，因其有著隔噪音、驅(qū)蚊蟲、凈空氣等功能而被廣泛用于庭院觀賞及園林綠化，是我國獨有的二級保護樹種[1] 。閩楠分布范圍廣，對其生長所需的土質(zhì)要求不嚴，生長較為迅速，其曲干通直、冠大蔭濃、樹體造型優(yōu)美，自古以來便是建筑、高級家具和精密木模的優(yōu)良用材，但由于近些年人類的過度采伐以及對野生資源生境的破壞，閩楠天然資源已經(jīng)難覓其蹤[2]，雖近些年大力發(fā)展人工楠木林，但由于經(jīng)營效果不佳，未能解決其根本問題[3]，因此拯救、保護閩楠天然資源已迫在眉睫。……
