红豆树人工纯林与混交林比较研究

Comparative Research on Pure Plantation and Mixed Forest of Ormosia hosiei Hemsl et Wils

采用样地调查的方法,分析了红豆树人工纯林与混交林的生长特征数值。结果表明,谷地纯林的生长好于坡地,混交林中以红豆树、杉木2∶1混交更能促进红豆树的生长成材,红豆树纯林的成材效果比混交林好。文章指出,合理营造红豆树纯林可以提高成材率,从而达到经济效益的最大化。

Through the method of sample plot survey,growth characteristics index of artificial pure forest and mixed forest of Ormosia hosiei Hemsl et Wils was analyzed.The results showed that artificial pure forest grew better in valley than in sloping fields,the mixed forest of Ormosia hosiei and Cunninghamia lanceolata 2∶1 could promote the growth of Ormosia hosiei timber,timber effect of artificial pure forest of Ormosia hosiei was better than mixed forest.The maximization of economic benefit was achieved and the timber rate was improved through reasonable construction pure forest of Ormosia hosiei.
