Interplanting method of fast-growing eucalyptus and cunninghamia lanceolata

Abstract

The invention discloses an interplanting method of fast-growing eucalyptus and cunninghamia lanceolata. The interplanting method includes planting steps: (1), selecting a parcel with a thick soil layer without waterlogging; (2), transplanting: from February to May, digging holes and planting fast-growing encalyptus according to planting space of (1.5-2)mx(5-8)m, and digging holes and planting a row of cunninghamia lanceolata among row space of fast-growing encalyptus according to row space of 2-3m; (3), topdressing fast-growing encalyptus from February to April of each year; pruning and trimming parts below 1m after fast-growing encalyptus grows to 2m in height; applying decomposed fertilizer to cunninghamia lanceolata once a year according to 20-40kg per plant, ditching at positions of 0.5-1m distant from trunks during applying, applying the fertilizer into ditches, and covering with soil after fertilizing; (4), continuously felling fast-growing encalyptus according to needs after thefourth year of planting, felling according to needs after the fifth year of planting of cunninghamia lanceolata, digging up roots poor in germination according to germination conditions, and plantingin seedlings. By the method, the problem of water and soil loss caused by planting of fast-growing encalyptus can be solved effectively, and labor input for weeding and disease and pest of cunninghamia lanceolata can be reduced.

Description

technical field [0001] The invention relates to the technical field of tree planting, in particular to a method for interplanting fast-growing eucalyptus and Chinese fir. Background technique [0002] Fast-growing Eucalyptus, scientific name: Eucalyptus ( Eucalyptus robusta Smith ), aliases: white diesel tree (Chaoshan), Mang tree (South Australia), eucalyptus, Eucalyptus euplica (Puning), Eucalyptus euphratica, Gary tree, Eucalyptus euplica (Huiyang). [0003] Fast-growing Eucalyptus refers to the hybrids of Eucalyptus macrophylla × Eucalyptus urophylla, Eucalyptus macrophyllum × Eucalyptus urophyllus, Eucalyptus merantifolia × Eucalyptus urophyllum, and Eucalyptus urophylla × Eucalyptus urophylla. There are many strains and they are named after series codes. The characteristics of each strain are different: the fast-growing ones reach a height of ten meters a year, the cold-resistant ones are more resistant to two degrees of low temperature than the original species, and ...
