| 摘 要： | 为验证多树种合理配置抗御杨树天牛灾害的效果,在宁夏新华桥种苗场的试验林内,选取受光肩星天牛危害的3种配置模式的林分为样地,通过对新疆杨标准木做树干解析.比较3种配置模式中新疆杨的单株总生长量,结果除胸径外,树高和材积的总生长量均存在显著差异;单株材积总生长量大小顺序为新疆杨和复叶槭混交林＞新疆杨和合作杨混交林＞新疆杨纯林,即混交林中天牛对新疆杨危害不同程度地小于新疆杨纯林.比较3种模式林分在单位面积上的总材积生长量,结果为新疆杨和复叶槭混交林＞新疆杨纯林＞新疆杨和合作杨的混交林.同时考虑目标树种的单株材积生长量和该配置模式单位面积上的总材积生长量,新疆杨和复叶槭混交林是3种模式中最理想的. |

| Abstract: | In order to confirm the effect that reasonable disposition of multi-tree species has the potential to increase resistance of trees to Anoplophora glabripennis,three different disposition model forests were sampled in experimental forest belonging to Xinhuaqiao Farm of Tree Seed and Seeding in Ningxia.By conducting stem analysis for standard tree of P.alba var.pyramidalis,the increments of P.alba var.pyramidalis within three disposition models were cpmpared.The results are described as follows,there were significant differences in the height and timber volume within three different disposition model forest(difference level 99%),but no significant difference in dbh of P.alba var.pyramidalis was observed.(Among) them,the individual P.alba var.pyramidalis with the greatest increment of total timber volume was that in mixed forest of P.alba var.pyramidalis and Acer negundo,followed by that in mixded forest of P.alba var.pyramidalis and Populus×xiaozhuanica cv.'Opera'and that in the pure forest of P. alba var.pyramidalis.More or less,the growth status of P.alba var.pyramidalis in the mixed forest with multi-tree species disposition was better than that in pure forest.While,the comparison of the increments of total timber volume per ha of three different disposition model forests showed that the largest one was that in the mixed forest of P.alba var.pyramidalis and Acer negundo,followed by that in the pure forest of P.alba var.pyramidalis and that in mixded forest of P.alba var.pyramidalis and Populus×xiaozhuanica cv.'Opera'.Taking into account the individual timber volume increments and the total increments of forest tree timber volume per ha,was showed that the mixed forest of P.alba var.pyramidalis and Acer negundo was the best among the 3 models. |
