摘要
在马尾松采伐迹地,进行了营造降香黄檀福建柏混交林、纯林试验,经过8年的经营管理,林木生长良好,调查可知,降香黄檀与福建柏混交造林生长的林分,比降香黄檀福建柏纯林生长的林分效果好。结果表明:降香黄檀福建柏混交林的林木生长量平均树高、胸径、枝下高、冠幅、单株材积、林木蓄积量,分别比降香黄檀、福建柏平均树高大8.76%、26.30%,胸径粗12.65%、29.85%,枝下高17.65%、61.29%,冠幅大7.22%、35.87%,单株材积大30.77%、112.50%,蓄积量大22.03%、94.50%。土壤肥力也提到了提高。
Dalbergia odorifera,Fokienia hodginsiii and the mixed forest were built respectively in the cutting blank of Pinus massoniana,and the trees grow well after 8years of tending.The forest stands are compared between the pure and mixed forest.The results indicate that the average height,dbh,under branch height,crown width,single volume and volume of Dalbergia odorifera and Fokienia hodginsii in mixed forest are all higher than those of the two respectively in pure forest accounting for 8.76% and 26.30%,12.65% and 29.85%,17.65% and 61.29%,7.22%and 35.87%,30.77%and 112.50%,22.03%and 94.50%.
