Initial Growth Effects of Mixed Eucalyptus urophylla × E. grandis and Acacia melanoxylon Plantations
To investigate mixed patterns of Eucalyptus plantations in southern Guangxi,this study compared and analyzed the growth of 1.5-year-old E. urophylla × E. grandis and Acacia melanoxylon under four different mixing ratios,alongside their 1.5-year-old pure plantations. The results indicated that at certain mixing ratios,the height,diameter at breast height (DBH),and height to the first branch of both E. urophylla × E. grandis and A. melanoxylon surpassed those in their respective pure plantations. Among the mixed patterns,the E. urophylla × E. grandis × A. melanoxylon (3︰1) ratio demonstrated the most pronounced growth enhancement for both species,with increases of 37.1％,28.2％,and 20.5％ in height,DBH,and height to the first branch,respectively,compared to pure E. urophylla × E. grandis plantations,and 11.8％,31.1％,and 32.7％ compared to pure A. melanoxylon plantations.
