摘　　要：为提升闽楠造林成效,采用不同施基肥措施进行闽楠造林试验,结果表明:不同施基肥措施下,闽楠平均地径、平均当年抽高、平均冠幅均存在极显著差异;平均树高、平均成活率不存在显著差异。肥种的选择要比施肥量的多寡更能影响闽楠地径、苗高、冠幅的生长,也影响着闽楠的造林成活率。施用丹王复合肥和科沃特有机肥均可有效促进闽楠地径、苗高、冠幅的生长,但施用鄂中复合肥的效果却不大明显。闽楠地径生长量与树高生长量、成活率呈负相关关系,相关系数分别为-0.06和-0.43,与当年抽高、冠幅呈正相关关系,相关系数分别为0.12和0.28,但相关关系均不显著。树高与当年抽高具极显著正相关关系,相关系数为0.74。肥种选择不当、施肥过量和不足都难以提高闽楠造林成效,适量施肥(复合肥肥量应控制在150 g·株^(-1),有机肥肥量应控制在1.0~1.5 kg·株^(-1))才能有效提高闽楠造林成效。其中每株施科沃特有机肥1.5 kg作基肥造林成效最好,在此处理下,采用1年生闽楠造林1年后,平均地径、树高、当年抽高、冠幅、成活率分别为5.56 mm、62.46 cm、26.70 cm、32.97 cm、98.33%。In order to improve the afforestation effectiveness of Phoebe bournei,different basal fertilizer measures were used to carry out afforestation test of Phoebe bournei.Result shows that the average ground diameter,average height of the current year&average crown width of Phoebe bournei existed very significant difference under different basal fertilizer measures.There is no significant difference in average tree height&average survival rate.The choice of fertilizer species can affect the growth of Phoebe bournei's ground diameter,seedling height&crown width more than the amount of fertilizer applied,and also affect the survival rate of Phoebe bournei afforestation.The application of Danwang compound fertilizer&Kovot organic fertilizer can effectively promote the growth of Phoebe bournei ground diameter,seedling height&crown width,but the effect of applying compound fertilizer in Hubei is not obvious.The ground diameter growth of Phoebe bournei is negatively correlated with tree height growth&survival rate.The correlation coefficients are-0.06&-0.43,respectively.There is a positive correlation with the height&crown width of the year.The correlation coefficients are 0.12&0.28,but the correlations are both not significant.The tree height has a very significant positive correlation with the current year's height,with a correlation coefficient of 0.74.Improper selection of fertilizer species,excessive&insufficient fertilization are difficult to improve the afforestation effect of Phoebe bournei.Appropriate fertilization(the amount of compound fertilizer should be controlled at 150 g/plant,and the amount of organic fertilizer should be controlled at 1.0-1.5 kg/plant)in order to effectively promote Phoebe bournei afforestation effectiveness.Among them,applying 1.5 kg of Kovot organic fertilizer as base fertilizer for each plant has the best afforestation effect.Under this treatment,after 1 year of Phoebe bournei afforestation,the average ground diameter,tree height,height of the year,crown width,and survival rate are resp
