Effective of planted density on growth of Melaleuca provenances in Thanh Hoa, Long An province

Abstract

The planted density of trees effects on the growth of plantation and planted expense. However, depending on planted purpose, the size of forest products and the length of rotation, the planted density will be decided. The Melaleuca plantation with planted density 40.000 trees/ha for local provenance is established to supply the poles (the length 4m and diameter
of top > 4cm). Sine 1994, a lot of Australia Melaleuca provenance and species have been imported to try in Mekong river delta. General words, they grow very fast to compare with local one. This paper shows the data of effectiveness of planted density of different Melaleuca species and provenances on growth of plantation. Experimental result shows that: the
planted density of M.leucadendra and M.viridiflora should be 6666 - 10000 stocks/ha with purpose to product a poles. For M.cajuputy, the planted density is 20000 stocks/ha considering to apply. Experiment points the bestof growing belongs to M.leucadendra, next is M.viridiflora and M.cajuputy.
