| 摘 要： | 对广西苍梧县国有天洪岭林场35年生的7种密度的马尾松林分进行采脂试验,结果表明:不同密度林分单位面积产脂量差异显著,低密度时,林分单位面积产脂量随着密度增大而增加,达到一定密度后,产脂量又随着密度的增加而减少;年平均单株产脂量则随着密度的增加而减少。在松脂主产区,进入成熟期的马尾松林分保留600~700株.hm-2的密度,产脂量高且经营效益好。 |

| Abstract: | The resin collection experiment of 7 kinds of density of 35-years-old Pinus massoniana forest was conducted,the results showed that there were obvious different resin yields among different denstities of stands.the resin production with low density increased with density increascing but it decreased with density increasing when it got to a certain high level.The annual average individuals resin yield always decreased with density increasing.In the main resin production area,the reasonable density of P.masso... |
