【摘要】 为研究大花序桉（Eucalyptus cloeziana）与红锥（Castanopsis hystrix）、火力楠（Michelia macclurei）和闽楠（Phoebe bournei）混交造林初期林分产量效应，以 3.5 年生大花序桉与红锥、火力楠、闽楠混交林为研究对象，调查并分析各处理林木单株材积、林分蓄积量。结果显示，在高峰试验点，MD4处理的大花序桉平均单株材积最大，比PD1处理高出14.23%;MD1和MD2 处理的红锥平均单株材积比 PD2 处理分别高出 14.29% 和 12.68%;MD3 和 MD4 处理的火力楠平均单株材积比 PD3 处理分别高出 26.87% 和 32.93%。在大桂山试验点，ML1 处理的大花序桉平均单株材积最大，比 PL1 处理高出 14.52%;ML1和 ML3处理的闽楠平均单株材积比 PL2处理分别高出 11.17% 和 4.96%。在高峰试验点，MD1、MD2、MD3和 MD4处理的林分蓄积量分别为 53.05、52.91、53.42 和 53.79 m~3/hm~2，分别是 PD1 处理林分蓄积量的 0.96、0.96、0.97 和 0.98 倍；在大桂山试验点，ML1、ML2 和 ML3 混交处理的林分蓄积量分别为 59.42、46.92 和 46.98 m~3/hm~2，分别是 PL1 处理林分蓄积量的 0.97、0.76 和 0.76 倍。综合单株材积及蓄积生长量指标，9 行大花序桉 + 3 行红锥/火力楠、8 行大花序桉 + 2 行红锥/火力楠、9 行大花序桉 + 3行闽楠模式较好。更多还原

【Abstract】 To study effects of stand yields at initial stage of mixed afforestation of Eucalyptus cloeziana with Castanopsis hystrix, Michelia macclurei and Phoebe bournei, taking 3.5-year-old E. cloeziana mixed plantations with C. hystrix, M. macclurei and P. bournei planted in Gaofeng and Daguishan forest farms as research objects individual volumes and stand accumulations of different treatments were investigated and analyzed. Results showed that in Gaofeng forest farm, average individual volume of MD4 treatment was the largest, which was14.23% larger than that of PD1 treatment. Average individual volumes of C. hystrix of MD1 and MD2 treat‐ments were 14.29% and 12.68% larger than that of PD2 treatment. Average individual volumes of M. macclurei of MD3 and MD4 treatments were 26.87% and 32.93% larger than that of PD3 treatment. In Daguishan forest farm, average individual volume of ML1 treatment was the largest, which was 14.52% larger than that of PL1treatment. Average individual volumes of P. bournei of ML1 and ML3 treatments were 11.17% and 4.96% larg‐er than that of PL2 treatment. In Gaofeng forest farm, stand accumulations of MD1, MD2, MD3 and MD4 treat‐ments were 53.05, 52.91, 53.42 and 53.79 m~3/hm~2, which were 0.96, 0.96, 0.97 and 0.98 times of stand accumu‐lation of PD1 treatment. In Daguishan forest farm, stand accumulations of ML1, ML2 and ML3 treatments were59.42, 46.92 and 46.98 m~3/hm~2, which were 0.97, 0.76 and 0.76 times of stand accumulation of PL1 treatment Considering individual volume and volume growth index, 9 rows of E. cloeziana + 3 rows of C. hystrix/M. macclurei, 8 rows of E. cloeziana + 2 rows of C. hystrix/M. macclurei, and 9 rows of E. cloeziana + 3 rows of P. bournei were better.更多还原
