摘  要：
在13年生马尾松林分中,通过间伐,在林下套种鹿角栲、格氏栲和苦槠等3种珍贵阔叶树种。采用裂区试验设计,选择上层林马尾松保留密度为主处理,分别设0(裸地)、600、900、1125株·hm-24个水平;副处理为鹿角栲、格氏栲和苦槠3种栲属树种。试验结果表明:在马尾松林下套种鹿角栲、格氏栲、苦槠3个树种,造林成活率较高,生长速度较快;保留的马尾松生长量得到提高,有利于培育马尾松大径材。上层林密度控制在900～1125株·hm-2为宜。异龄复层林枯枝落叶量大,同时可以改善林分小气候,有利于早期较耐荫鹿角栲、格氏栲、苦槠树的生长,促进枯枝落叶的分解,改善土壤肥力。表明马尾松林下套种栲属阔叶树种是一条培育马尾松大径材,保护和发展中亚热带珍贵阔叶树种,同时提高生态功能的有效途径。

摘  要：
In the 13-year-old Pinus massoniana forest,by thinning,Castanopsis lamontii,Castanopsis kawakamii and Castanopsis sclerophylla 3 kinds of valuable hardwood species were intercropped under the stands.Using split-plot experimental design,the upper forest Pinus massoniana retained density was chosen as the key treatment,0(bare ground),600,900,1125 strains·hm-2 4 levels were taken;Castanopsis lamontii,Castanopsis kawakamii and Castanopsis sclerophylla was chosen as the assistant treatment.The experimental results showed that:intercropping Castanopsis lamontii,Castanopsis kawakamii and Castanopsis sclerophylla three species under the pine forest had the higher survival rate and growth speed;retained Pinus massoniana growth increment was improved,which was conducive to fostering large-diameter timber pine.The superstratum forest density was appropriate to be controlled in 900 ~1125trees·hm-2.The uneven-aged re-storied forest had large amount of litters,and could improve the forest microclimate,which was conducive to shade-tolerant Castanopsis lamontii,Castanopsis kawakamii and Castanopsis sclerophylla tree growth at the early stage,promoted the decomposition of litter,improved the soil fertility.It showed that intercropping Castanopsis broad-leaved species under Pinus massoniana forest was an effective way for large-diameter Pinus massoniana timber cultivation,protection and development of precious mid-asian tropical hardwood species,and improving the ecological function.
