Method for mixed cultivation of eucalyptus and fast-growing acacia

Abstract

A method for mixed cultivation of eucalyptus and fast-growing acacia includes the following steps: using half-year-old eucalyptus container seedlings and fast-growing acacia container seedlings as afforestation materials; conducting strip cleaning of the afforestation land and block site preparation; planting 2 trees in the same large-sized afforestation hole; performing hole cultivation two months before planting; backfilling the hole soil one month before afforestation, and applying organic fertilizer as base fertilizer when the hole soil is backfilled to 1 / 3; conducting afforestation within 2 months after the completion of site preparation; continuously tending for 3 years after afforestation, including weeding and topdressing twice a year. The invention adjusts the tree species structure, increases the spacing between rows and holes in the stand, changes the ventilation conditions in the eucalyptus plantation, optimizes the light environment and nutrient environment of the stand, forms a good multi-layered forest structure, and provides technical support for improving the planting mode and sustainable management of eucalyptus plantations.
