摘　　要：为寻求适宜苦楝种子育苗的容器基质,利用容器育苗成型技术,在泥炭中添加不同比例的珍珠岩和蛭石,研究不同容器育苗基质对苦楝种子出苗及生长的影响,并采用因子分析法对苦楝的育苗效果进行综合评价。结果表明:T3(V泥炭:V珍珠岩=1:1)和T5(V泥炭:V蛭石=2:1)处理苦楝叶片的光合速率和蒸腾速率显著低于其他处理,T4(V泥炭:V蛭石=3:1)处理的光合速率和蒸腾速率相对较强。T1(V泥炭:V珍珠岩=3:1)和T2(V泥炭:V珍珠岩=2:1)处理的苦楝出苗率最高,均达到了97.9%,T3、T5和T7(V泥炭:V蛭石:V珍珠岩=6:1:1)处理显著低于其他试验处理,分别仅为88.7%、85.4%和85.4%。多重比较结果表明,T2、T6(V泥炭:V蛭石=1:1)和T7的株高和地径显著大于其他试验处理,而T5处理则显著低于试验处理,T6处理的地上部生物量和地下部生物量相对较高,而T3和T5处理的生物量显著最低,各处理间不同指标的表现并不完全吻合。利用因子分析法综合评价不同容器育苗基质苦楝的育苗效果是适宜的。对苦楝的出苗率、株高、地径、地上部分和地下部分鲜重等5个指标进行因子分析,结果表明,T6为苦楝容器育苗最佳配比基质,其次为T7和T4,T3综合育苗效果最差。To study the suitable seeding container substrate in Melia azedarach cultivation,pearlite and vermiculite were mixed in peat.Effect of different container nursery substrate and on emergence and growth of Melia azedarach seeding were studied.Besides,we valuated the nursery effect of different container substrate by factor analysis method.Photosynthetic rate and transpiration rate were significant lower in T3 （V peat：V pearlite=1：1） and T5 （V peat：V vermiculite=2：1）.However,photosynthetic rate and transpiration rate were highest in T4 （V peat：V vermiculite=3：1） of all the treatments.Melia azedarach emergence rate of T1 （V peat：V pearlite =3：1） and T2 （V peat：V pearlite =2：1） was significant higher than other treatments being 97.9%.However,Melia azedarach emergence rate of T3,T5 and T7 （V peat：V vermiculite：V pearlite =6：1：1） was significant lower being 88.7% 、 85.4% and 85.4%,respectively.Seedling height,and ground diameter of Melia azedarach in T2,T6 （V peat：V vermiculite =1：1） and T7 were higher than other treatments.While in T5,seedling height,and ground diameter were lowest.Biomass of Melia azedarach in T6 was highest in all of the treatments,while in T3 and T5,it was lowest.Index of Melia azedarach growth and emergence in different treatments were not coincident.Factor analysis method wassuitable for valuation on the nursery effect.Factor analysis about emergence,seedling height,ground diameter and biomass of Melia azedarach were made in this article.Result showed that T6 was the best compound substrate for Melia azedarach cultivation,next came T7 and T4,while T3 was the worst in all the treatments.
