Research on the adaptability and selection of precious tree species in the mountainous regions of Southern Fujian Province
To screen for suitable tree species for cultivation in the mountainous areas of Southern Fujian,the Biqing State Owned Forest Farm in Yongchun,Fujian Province was selected as the experimental site,a total of 70 different precious species were selected for the research subject,including 20 excellent landscape trees such as Koelreuteria bipinnata integrifoliola(Merr.),Koelreuteria elegans subsp.formosana,Melia azedarach,and Ilex chinensis Sims,30 excellent timber tree species such as Cryptomeria japonica var.sinensis,Taiwania cryptomerioides Hayata,Fokienia hodginsii(Dunn),Ormosia henryi Prain,and Ormosia hosiei Hemsl,and 20 multifunctional tree species of the Fagaceae family such as Cyclobalanopsis chungii(Metc.),Quercus gilva Blume,Quercus glauca Thunb.,and Quercus sessilifolia Blume,determined its survival rate,preservation rate,growth and health status,and adaptability in the mountainous areas of Southern Fujian.The results showed that the survival rates of various tested tree species selected for afforestation are relatively high,except for Quercus sessilifolia Blume,all others are above 85%,and the preservation rates are above 90%;the overall growth and health status of the tree species are good,with strong adaptability.5 excellent landscape tree species suitable for cultivation in the mountainous areas of Southern Fujian were selected such as Ilex chinensis Sims,Cyclocarya paliurus(Batal.),Liriodendron chinense(Hemsl.),Liquidambar formosana Hance,and Semiliquidambar cathayensis,6 excellent timber tree species were selected such as Taiwania cryptomerioides Hayata,Michelia macclurei Dandy,Phoebe bournei(Hemsl.),Camphora officinarum Nees ex Wall,Eucalyptus cloeziana,and Schima superba,and 4 multifunctional tree species of the Fagaceae family were selected such as Cyclobalanopsis chungii(Metc.),Quercus gilva Blume,Castanopsis hystrix Hook.,and Castanopsis chinensis(Spreng.)Hance.This study provides a reference for the conservation of bio-diversity,ex situ protection of plants,and introduction and domestication research in the mountainous areas of Southern Fujian.
