楠杉混交林营造技术研究报告

楠木是我国的珍贵用材树种。但生长慢、经济收入迟,人工造林不多。本楠杉混交林,楠木是目的树种,试验结果表明:2楠:1杉株间混交的较好;1楠:1杉株间混交则营造较简单,也是一种可应用的混交方式。混交林中的楠木比楠木纯林生长稍差,但其中的杉木生长很好,且杉木小径材有利用价值,提早收入,以短养长,以杉养楠,是当前发展楠木生产的一种切实有效的方法。

A Stady on Building Mixed Forest of Phoelbe Bournei and Cunnlnghamia Lancelata

Phoebe bournei is one species of valuable timbers trees in China, but it grows slowly and gains benifets late, so its area of man-made forest is no large. The test result of the mixed forest in which it is the chief species shous that the pattern of interlining mixture ( mixture proportion is 2: 1 ) can produce good effect; and that if mixture proportion is 1 : 1, the mixed forest can bc easily to build In me mixed forest, the phoebe bourhei trees do not grow as well as thale forest, but Cunninghamia Lanceolata can grow better. The undersized log of Chinese fir has use value, so mixture plomtation can gain benifets faster, using the short-term income will maintain Long-term cultirating of phlebe bou-rnei, and mixture plantation is a feasible way to develop Production of Phoebe bournei.
