摘    要:试验林采用正交设计,因素为树种、整地方式、密度、施肥,各因素取3个水平,3次重复。用生长量、生物量与投入产出进行评价。试验结果:3.5年生蓝桉、直干桉幼林最佳处理平均高9.5m,平均胸径8.9cm,每hm2蓄积量70.5126m3,最佳处理比最差处理树高大28.4%,胸径大34.9%,蓄积量大183%。用已取得的技术成果营造的示范林,3.5年生平均高9.8m,平均胸径6.5cm,累计产桉叶2.43万kg/hm2,3年生左右,通过桉油及薪柴的收入可以回收全部造林及加工成本。

关 键 词:蓝桉,直干桉,丰产栽培技术

Abstract:Designing the test forest with the factors are species, soil preparation, density and fertilization, 3 levels and replications were adopted to every factor and evaluated the test forest using growth, biomass and input-output as indexes, the results of test is following: As far as the best treatment of 3.5-year-old Eucalyptus globulus and Eucalyptus maidenii are concerned, the average height is 9. 5m, average DBH is 8. 9cm, accumulation quantity is 70.5126m3/hm2, the 3 indexes of the best treatment increased by 28. 4%, 34. 9% and 18.3% respectively as compared with those of the worst treatment, the demonstration forest constructed by using the technological achievement abtained. After 3. 5 years, the average height is 9.8m, average DBH is 6. 5cm, the output of eucalyptus leaves accumulated to 24. 3 thousand kg/hm2. After 3 years or so, the income from eucalyptus oil and fuelwood can retrieve the whole cost of forestation and conversion.
Keywords:Eucalyptus globulus  Eucalyptus maidenii   high-yield cultivation techniques
