红豆树杉木混交造林试验初报

Preliminary Report on Mixed Afforestation of Ormosia hosiei and Cunninghamia lanceolata

以13年生杉木纯林、13年生红豆树及13年生1∶1红豆树-杉木混交林为试验对象,比较不同坡位间生长差异以及不同造林方式对杉木、红豆树生长的影响。结果表明:下坡位纯林和混交林均表现出生长效果最佳的状态;混交造林相比纯林更有利于培育大径材;各坡位混交造林对红豆树单株材积无明显的促进作用,但混交造林对杉木单株材积有明显的促进作用,且位于中坡坡位;与纯红豆树林相比,杉木与红豆树混交造林对单位面积内的生产力具有很大的促进作用。

Taking 13-year old pure Cunninghamia lanceolata forest,13-year old pure Ormosia hosiei forest,and 13-year old 1:1 mixed Cunninghamia lanceolata forest as experimental objects,the effects of different slope sites and different afforestation methods on the growth status of Cunninghamia lanceolata and Ormosia hosiei were compared.The results showed that both pure and mixed forests on the slope showed the best growth effect.Compared with pure forest,mixed afforestation is more beneficial to cultivating large-diameter timber.Mixed afforestation at each slope position had no significant effect on the volume of single plant of Ormosia hosiei,but mixed afforestation had significant effect on the volume of single plant of Cunninghamia lanceolata,and was located in the middle slope position.Compared with pure Ormosia hosiei forest,mixed afforestation of Cunninghamia lanceolata and Ormosia hosiei tree has a great effect on productivity per unit area.
