摘　　要：探讨了不同整地方式、不同的施肥处理对桉树人工林生长状况以及土壤的影响,旨在寻找一种适宜广西红壤区林地土壤高效、可持续的人工林经营方式。结果表明:①免炼山整地方式的桉树生长量显著高于炼山处理,同时由于对土壤扰动较少,有利于林地的高效、可持续经营;②炼山处理对土壤性质的影响主要体现在高温会减少土壤有机质的含量,同时在短期内释放大量养分元素;③施用不同类型的肥料对桉树人工林的生长与地力有着极大的影响,以生长量大小排序为:测土配方复合肥>复合肥>有机复混肥,说明施用专用配方肥料更有利于减少化肥施用量,提高林分生产力。提出了为实现林地生长量提升以及维持地力,应选择免炼山的整地方式,同时配合测土配方施肥技术以及增施有机肥,保证林地的高效、可持续经营。This study explored the effects of different land preparation methods and fertilization treatments on the growth status and soil of eucalyptus plantation,with a view to finding an efficient and sustainable plantation management mode that is suitable for forest land in Guangxi red soil region.The results showed that:①the growth of eucalyptus was significantly higher than that of mountain burning treatment,and it was conducive to the efficient and sustainable management of forest land due to less soil disturbance;②the effect of mountain burning on soil properties was mainly reflected in the reduction of soil organic matter content and the release of a large number of nutrient elements in a short period of time;③the application of different types of fertilizers has a great influence on the growth and soil fertility of eucalyptus plantation.The order of growth is soil testing formula compound fertilizer>compound fertilizer>organic compound fertilizer,which shows that the application of special formula fertilizer is more conducive to reducing the amount of chemical fertilizer and improving the productivity of forest.In order to improve the growth of forest land and maintain soil fertility,the soil preparation method without burning should be selected,combined with soil testing and formula fertilization technology and organic fertilizer application to ensure the efficient and sustainable management of forest land.
