Fast-growing eucalyptus and D. beecheyanavar. Pubescens (P .F .Li) Kengf. interplanting method

Abstract

The invention discloses a fast-growing eucalyptus and D. beecheyanavar. Pubescens (P .F .Li) Kengf. interplanting method which includes the planting steps: (1) selecting a land parcel with a deep soillayer and without accumulated water; (2) digging holes for planting fast-growing eucalyptus according to the planting space of (2-3)m*(12-20)m in February to May, and digging holes for planting a line of mother bamboos of the D. beecheyanavar. Pubescens (P .F .Li) Kengf. according to the row spacing of 4-5m in the middle of the line spacing of the fast-growing eucalyptus; (3) performing top application on the fast-growing eucalyptus in February to April every year, pruning portions below 1m positions of the fast-growing eucalyptus growing to reach the height of 2m, applying rotten fertilizersto the D. beecheyanavar. Pubescens (P .F .Li) Kengf. every year, hooking tips of new bamboos remaining in the current year, retaining 10-12 plates of branches and leaves per plant, annually retaining1-2 developed bamboos per clump and fully cutting away the rest bamboos; (4) cutting away the bamboos at the age of 2 years or more every year, cutting out old bamboo pockets, keeping 2-3 annual to biennial raw mother bamboos per clump, timely cutting down the fast-growing eucalyptus and implanting new tree seedlings according to conditions. By the method, the problem of water and soil loss caused by the fast-growing eucalyptus can be effectively solved, and weeding labor input can be decreased.
