明溪县不同楠木树种早期生长对比分析

Comparisive Analyse of Early Growth to Different Phoebe zhennan Species in Minxi County

在明溪县开展桢楠、紫楠、黄枝润楠和闽楠造林试验,研究其适应性及生长情况差异。对8 a生的试验林调查,结果表明:桢楠、紫楠和闽楠的造林成活率和保存率均高于80%,不同楠木之间的造林成活率和保存率均有显著差异,桢楠、紫楠和闽楠对造林区的适应性较强。紫楠、桢楠的胸径和单株材积均高于闽楠和黄枝润楠,不同楠木之间的胸径和单株材积差异显著,紫楠和桢楠的生长优势明显,适合在明溪县造林。

Plantative test was carried out to Phoebe zhennan、Phoebe sheareri、Phoebe bournei and Machilus versicolora in Minxi county to study their adoption and difference of growth.The results showed to 8-year test stands that plantative survive rate and preservation rate of Phoebe zhennan、Phoebe sheareri and Machilus versicolora were more than 80 percent.Plantative survive rate and preservation rate of different Phoebe zhennan Species had obvious different.Phoebe zhennan、Phoebe sheareri and Machilus versicolora had high adoption to plantative place.The DHB and volume of Phoebe zhennan and Phoebe sheareri were bigger than these to Phoebe bournei and Machilus versicolora.The Difference to the DHB and volume of different Phoebe zhennan Species was obvious.The growth of Phoebe zhennan and Phoebe sheareri was faster than that to another two tree species.Phoebe zhennan and Phoebe sheareri are suit to be plant in Minxi county.
