闽南西南桦与红锥混交造林2年试验初步效果

The Preliminary Afforestation Effect of the Mixed Forest Betula alnoides in Southern Fujian

通过引进西南桦组培无性系,2017年4月于福建省华安金山国有林场万世清工区开展混交造林试验,采用西南桦与红锥混交4种造林模式,2年后通过样地调查分析,结果表明:造林模式对西南桦早期生长表现影响不显著,各种西南桦混交模式树高、胸径、材积生长没有显著差异。西南桦有白蚂蚁、蟋蟀、天牛、木毒蛾危害。造林模式对红锥早期生长表现影响不显著,各种红锥混交模式树高、胸径生长没有显著差异。红锥有木毒蛾危害。

The tissue-cultured seedlings of Betula alnoides was introduced to plant in Wanshiqing Area of Fujian Hua’an Jinshan National Forest Farm.B.alnoides was mixed with Castanopsis hystrix with 4 modes in Wanshiqing Area.After two years the sample plots were set and each tree in the plots was investigated.The results showed the effects of the mix afforestation modes to the growth of B.alnoides were not significant difference in the early stage.There were not significant differences among tree height,DBH or volume,resepctively.The termites,crickets,Anoplophora chinensis,Batocera lineolata and Lymantria xylina were found damaging to the B.alnoide in Wanshiqing Area.The effects of the mix afforestation modes to the growth of C.hystrix were not significant difference in the early stage.There were not significant differences among tree height or DBH,resepctively.The Lymantria xylina was found damaging to the C.hystrix in Wanshiqing Area.
