摘要： 运用单因素随机区组设计实验方法,对接种不同益生菌的3.5年生巨尾桉广林9号人工林进行标准地生长因子调查,并分析其济效益,探讨接种益生菌对巨尾桉造林效果的影响,结果表明：通过接种益生菌N1、P1、40K的巨尾桉造林3.5年后,胸径比对照分别提高了15.3%、9.8%、24.7%；树高比对照分别提高了19.1%、15.0%、15.0%；林木单株材积比对照分别提高了53.4%、35.7%、70.9%。从经济效益指标看,接种益生菌的巨尾桉在投资利润率、利税率、净现值和内部收益率4个指标分别高出对照12.8以上、7.0%以上、47.3%以上、21.9%以上。统计分析结果表明：接种益生菌的巨尾桉的树高、胸径、单株材积和各项经济指标增长量都达到了显著水平,增长效果明显,其中以接种益生菌40K的巨尾桉获利最大,经济效益最好。

Abstract: The authors investigated the growth factors in sample plot of 3.5-year-old Eucalyptus grandis × E.urophylla‘GLGU9’plantation with the inoculation of different probiotics, and analyzed the economic benefit and the effect of vaccinating different probiotics on Eucalyptus grandis × E.urophylla‘GLGU9’, by using the single-factor randomized block design method. The results showed that: compared with control, after 3.5 years afforestation of Eucalyptus grandis × E.urophylla‘GLGU9’vaccinating N1, P1 and 40K, DBH, tree height and single timber volume increased by 15.3%, 9.8%, 24.7%; 19.1%, 15.0%, 15.0%; 53.4%, 35.7%, 70.9%, respectively. From the perspective of economic efficiency indicators, the investment profit rate, the profit and tax, the net present value and the internal rate of return increased more than 12.8%, 7.0%, 47.3% and 21.9% compared with those of control. The statistical analysis indicated that the increase of tree height, DBH, single timber volume and the indicators of economic growth of Eucalyptus grandis × E.urophylla ‘GLGU9’vaccinating probiotics were obvious and reached significant level, among them, Eucalyptus grandis× E.urophylla‘GLGU9’vaccinating 40K had gained the maximum profit and had the best economic benefit.
