摘要
选择巨尾桉、马尾松、木荷分别与杉木进行混交造林,以杉木纯林作对照,对造林4年后的生长数据进行调查,结果表明:杉木+巨尾桉混交中杉木的树高和蓄积量显著高于其他模式,巨尾桉的生长和蓄积量也显著高于其他混交树种,林分总蓄积量显著大于其他模式,可见,巨尾桉对杉木的树高生长具有明显的促进作用,提高了林分蓄积量和林地生长率。
Eucalyptus urophylla× E .grandi ,Pinus massoniana Schimasuperba were mixed with Cunninghamia lanceolata ,choosing pure forest of Cunninghamia lanceolata as contrast ,the growth data after four years were in-vestigated .Result shows that :thetreeheight volumeof Cunninghamialanceolatain Eucalyptusurophylla× E. grandi + Cunninghamia lanceolata mixed forest is significantly higher than that in other patterns ;the growthvolumeof Eucalyptusurophylla×E.grandiarealsohigherthanothermixedtreespecies ;thetotalvolumewassig-nificantly higher than other patterns ;visibly ,there was obvious promoting effect from Eucalyptus urophylla × E . grandi to Cunninghamia lanceolata ,which improved the stand volume and growth rate in the forest land .
