摘要
通过对桉树人工纯林采伐后开展桉树萌芽更新+套种杉木、桉树萌芽更新+套种火力楠、桉树萌芽更新+套种红锥3种混交林更新模式与桉树萌芽更新纯林对比试验,6年后调查试验林生长量,并分析土壤理化性质,结果表明:萌芽更新套种的3种混交林,其桉树平均胸径、树高、单株材积均显著大于纯林,混交林林分总蓄积量与纯林没有显著差异,但混交林的土壤比纯林更加疏松透气、肥力更高,更有利于持续经营。
In Anxi County, southern Fujian region, the renewal mode of three mixed forests was compared with the pure forest of Eucalyptus budding renewal + set of fir, Eucalyptus budding renewal + set of firepower, Eucalyptus budding renewal + set of red cone and pure forest with Eucalyptus budding renewal after harvesting, and the growth of the experimental forest was investigated after 6 years. The soil physicochemical properties were analyzed. The results showed that the average breast diameter, tree height and single plant volume of Eucalyptus trees in the budding renewal + set of mixed forest were significantly greater than those in pure forest, and the total forest stand stock of mixed forest was not significantly different from that of pure forest. However, the soil of mixed forest is looser and more permeable than pure forest, which is more conducive to sustainable management.
