在杉木采伐迹地营造马尾松(A)、木荷(B)纯林及混交林(C)试验,经过15a的经营管理,对林木生长效果和土壤理化性质进行对比分析。结果显示:马尾松、木荷混交林(C)的林分生长量平均树高、胸径、枝下高、树冠、蓄积量,分别比马尾松(A)、木荷(B)纯林的林分生长量平均树高大15.11%、8.24%,胸径粗21.89%、10.30%,枝下高大29.7%、7.38%,树冠大7.83%、19.73%,单株材积大30.77%、57.69%,蓄积量多32.32%、57.87%。土壤肥力测定:马尾松木荷混交林(C)的土壤N、P、K养分含量,比马尾松木荷纯林(A、B)的土壤N、P、K养分含量均有所提高。

Create Masson pine fir deforested land (A)Superba(B) Chunlin,mixed (C) trials,after 15 years of business management,the effect on tree growth and soil properties were analyzed. The results show:Mixed Forest stand growth per hectare average tree height,diameter,under the branches high,crown,volume, respectively,compared with pine,Pure Forest growth per hectare average tree stands tall 15.11%,8.24%, 21.89% crude DBH,10.30%,29.7% under branch tall,7.38%,crown big 7.83%,19.73%,individual volume large30.77%、57.69%,volume more than 32.32%,57.87%.Soil fertility determination:Mixed Forest (C) of soil N,P,K nutrient content than the Masson Pine Pure Forest (A,B) of soil N,P,K nutrient content were improved.
