| 摘 要： | 通过对尾巨桉与马尾松不同混交比例、3年生生长效果调查,结果表明:尾巨桉纯林(CK1)单株平均胸径、树高、单株材积较不同比例混交林中的处理1、处理2、处理3尾巨桉平均胸径、树高、单株材积分别降低27%,42%,45%;17.2%,28.4%,30.9%;70.3%,126.7%,142%,不同比例混交林的处理1、处理2、处理3的马尾松单株平均胸径,树高与纯林马尾松(CK2)比较,树高生长各林分之间没有明显差异,平均胸径生长分别降低79.8%,25.6%,2.6%.尾巨桉纯林单位面积蓄积量与不同混交林的处理1,处理2,处理3的蓄积量分别是87.6,74.6,66.2,53m3/hm2.从3年生林分的各性状生长结果分析,不同比例混交林的林木生长以处理2表现效果最具生长潜力,有利于林木生长,对尾巨桉栽植风险具有缓冲作用,也有利于林地地力的恢复,对生产实践具有一定探讨价值.

Study on the Afforestation Effect of the Different Mixed Treatment Stands of Three-year-old for Eucalptus grandis var and Masson pine |
| |
| Abstract: | Through investigating the growing quantity of the mixed stands of the Eucalyptus grandis var and Masson pine in three year old The results were as following:the average diameter of breast height,height and stem volume of individual tree in the pure stand of Eucalyptus grandis var were decreased compared with those of treatment 1,treatment 2 and treatment 3,about 27%,42%,45%,172%,284%,309%,203%,1267%,142%,respectively.The average diameter of breast height of Masson pine in the treatment 1,treatment 2 and treatment 3 stands were decreased compared with those in the pure stand of Masson pine,about 798%,256%,26%,respectively;the average height of Masson pine weren′t evident in the different treatment and pure standsThe unit volume of Eucalyptus grandis in the pure stand,treatment 1,treatment 2 and treatment 3 stands were 876,746,662,53 m3/hm2 respectivelyThe results showed the mixed stands of Eucalyptus grandis var grew faster than the pure stand at present and are benefit for the tree growing and the soil fertilizing protecting The stands growing of Massion pine in the purity stand were better than others treatment stands of its Through the results analysis,the treatment 2 was regarded as the most potential growing power which has an important value in practice and applying |
