摘　　要：为了筛选出最适合吉林西部栗钙土区经济树种的造林模式,通过4个经济树种(山杏、沙棘、柠条锦鸡儿、柽柳)、6个造林配置模式(山杏×沙棘、山杏×柠条锦鸡儿、山杏×柽柳、柽柳×沙棘、柽柳×柠条锦鸡儿、沙棘×柠条锦鸡儿),采用带状混交于栗钙土区进行造林试验,分析栗钙土区不同造林配置模式下的造林成活率、生长量等。结果表明:在不同模式下各树种的造林成活率存在一定的差异,模式5和模式6中的柠条锦鸡儿、模式4中的柽柳成活率最高,达到100%,模式2中山杏的成活率最低,为54.5%,其他配置模式苗木成活率均达到64%以上,4个树种总平均成活率为82%以上。在不同模式下各树种的平均树高、地径和冠幅均随着树龄的增加而增加。不同的造林模式下相同树种2023年的树高、地径和冠幅大部分均显著高于2022年,只有柽柳模式4中的树高和模式4与5的地径在2022年和2023年的差异不显著。4个树种在树高方面,山杏与沙棘、山杏与柠条锦鸡儿、沙棘与柠条锦鸡儿之间的差异不显著;在地径方面,山杏与柠条锦鸡儿、山杏与柽柳之间的差异不显著;在冠幅方面,沙棘与柽柳、山杏与柽柳之间的差异不显著。模式6(沙棘×柠条锦鸡儿)为栗钙土区最佳造林模式,模式5(柽柳×柠条锦鸡儿)次之,以这2种模式在栗钙土区造林,既可以确保苗木成活率及生长量,又能达到在生长空间上相互平衡。The purpose of this study is to select the most suitable afforestation model of economic tree species in chestnut soil area of western Jilin Province.Afforestation experiment was carried out in chestnut soil area by using 4 economic tree species[Armeniaca sibirica(L.)Lam.,Hippophae rhamnoides Linn.,Caragana Korshinskii.Kom.,Tamarix chinensis Lour.]and 6 planting patterns[Armeniaca sibirica(L.)Lam.×Hippophae rhamnoides Linn.,Armeniaca sibirica(L.)Lam.×Caragana Korshinskii.Kom.,Armeniaca sibirica(L.)Lam.×Tamarix chinensis Lour.,Tamarix chinensis Lour.×Hippophae rhamnoides Linn.,Tamarix chinensis Lour.×Caragana Korshinskii.Kom.,Hippophae rhamnoides Linn.×Caragana Korshinskii.Kom.].The survival rate and growth rate of forestation under different afforestation configuration in chestnut calcium soil area were analyzed.The results show that:There are some differences in the survival rate of different tree species under different models.The survival rate of Caragana Korshinskii.in model 5 and model 6 and Tamarix chinensis in model 4 was the highest,reaching 100%.The survival rate of Armeniaca sibirica(L.)Lam.in mode 2 was the lowest(54.5%).The survival rate of other allocation modes was above 64%,and the average survival rate of 4 species was above 82%.The average height,ground diameter and crown width of each species in different models increased with the increase of tree age.Most of the tree height,ground diameter and crown width of the same tree species in 2023 were significantly higher than those in 2022 under different afforestation models.Only the tree height of Tamarix chinensis Lour.in model 4 and the ground diameter of model 4 and Model 5 are not significantly different in 2022 and 2023.In terms of tree height,there was no significant difference between Armeniaca sibirica(L.)Lam.and Hippophae rhamnoides Linn.,Armeniaca sibirica(L.)Lam.and Caragana Korshinskii.Kom.,Hippophae rhamnoides Linn.and Caragana Korshinskii.Kom..In terms of ground diameter,there was no significant difference between Armeniaca sibiri
