摘要
对10种桉树与相思混交模式林分的生长量、生物量、经济效益、土壤性质等方面的研究表明:桉树与相思混交能够提高混交林中桉树的胸径和材积生长量,但在造林密度相同的条件下,混交林分无论从产量还是从经济效益上都不如桉树纯林高,营造混交林能够很好地维持地力,提高林地土壤养分含量。
The growth, biomass, economic benefit and soil properties of ten eucalyptus mixed plantation regimes were studied. Results showed that eucalyptus mixing with Acacia crassicarpa improves the diameter and volume growth of eucalyptus. The wood yield and economic benefit of the mixed plantations are lower than those of the pure stands under the same planting density, but mixing plantings of eucalyptus with A. crassicarpa keeps the soil in better condition than under pure eucalyptus, so the soil nutrient content increases.
