摘　　要：用广东常见的两种菌根真菌纯菌剂以及彩色豆马勃的孢子粉 ,对加勒比松及湿地松幼苗实施人工接种。结果表明 ,菌根接种对幼树生长的促生效果明显 ,1 .5年生湿地松树高增幅达 1 0 .94 % ;2年生加勒比松树高增幅达 2 0 .37% ;3年生加勒比松树高增幅达 1 3.54%～2 2 .35% ;5年生加勒松树高增幅达 31 .1 3% ;胸径也有较大的增幅。接种 5年的加勒比松幼林蓄积量达 1 6 .82m3 /hm2 ,比对照的增加 87.1 % ,效果十分显著。Research results showed that the inoculation effects of Pinus elliotii and P. caribaea seedlings with mycelium and spores of ectomycorrhizal fungi were indicated. Eighteen months after inoculation, the average heights of P. elliotii increased by 10.94% . Two years, three years and five years after inoculation, the average heights of P. caribaea seedlings were increased by 20.37%, 22.35% and 31.13% respectively compared to those controls. After five years, the store of P. caribaea planted forest was 16.82 m 3/hm 2, increased by 87.1% than control.\;
