杉木柳杉混交效益调查

杉木在我区生长很不理想，为探索我区杉木进行的科学育林途径，对在我区生长的杉木柳杉混交林进行调查、统计分析，并将混交林中的杉木、柳杉与相应的杉木、柳杉纯林进行比较，其总平均生长量存在差异，但不显著，从生长势上相比较，杉木柳杉混产林的好于相应的纯林，通过科学培育，混交林中的杉木可望培育成中径材

Investigation on Benefits of Mingled Forest of Cuninghamia lanceolata and Cryptomeria fortunei

In order to explore scientific approach to rapid growth and high yielding of Cuninghamia lanceolata, investigation and statistic analysis were made on the minfled forests in Ouhai district. The results were showed that the ensemble means of growth had insignificant difference between Cuninghamia lanceolata, cryptomeria fortunei in the mingled forests and corresponding pure forests, and that the growth potential of mingled forest was better than that of corresponding pure forests. By scientific fostering, Cuninghamia lanceolata in the mingled forests can be developed into Middle-diameter tumber.
