摘  要：
在对闽南桉树林地土壤养分进行调查分析与评价的基础上,于2016年采用尾巨桉DH32-29轻基质网袋苗开展造林施肥中试试验,探讨不同施肥处理对尾巨桉人工林生长量的影响。结果表明:九龙江流域漳州段桉树林地土壤有机质、水解氮和速效钾含量仅为中等偏下水平,全氮、全磷和速效磷极端贫乏,部分地域有效锌和硼的含量极低,土壤交换性钙和交换性镁含量也普遍贫乏,土壤普遍呈酸性或强酸性。配方施肥中试表明,最优配方施肥方案:每穴施钙镁磷500 g+复合肥250 g作基肥,当年第1次追施尿素25 g+复合肥25 g+ZnSO_4 4 g+硼砂10 g,当年第2次追施尿素120 g+NPK复合肥120 g,第2年追施复合肥150 g+尿素150 g。该施肥模式下,桉树人工林生长最佳,2. 5年生林分树高、胸径、单株材积分别可达17. 10 m、12. 80 cm、0. 138 m~3。

摘  要：
Based on the investigation,analysis and evaluation for soil nutrients of Eucalyptus forest land in Southern Fujian,Eucalyptus urophylla afforestation fertilization experiment was carried out in 2016,the effects of different fertilization treatments on the growth of Eucalyptus urophylla plantations were discussed. The results showed that soil organic matter,hydrolyzable nitrogen and available potassium of Eucalyptus plantation soil in Zhangzhou Section of Jiulong River Basin accounted for only moderate to sub-level,total nitrogen,total phosphorus and available phosphorus were extremely poor,the available zinc and boron content is extremely low in some areas,the exchangeable calcium and exchangeable magnesium content is also generally poor,and the overall soil is acid or strongly acidic. Formula fertilization test results showed that the optimal formula fertilization scheme is that treatment 4: calcium magnesium phosphate 500 g + compound fertilizer 250 g as base fertilizer,the first top dressing in the first year: urea 25 g + NPK compound fertilizer 25 g + ZnSO_4 4 g + borax 10 g; the second top dressing in the first year: urea 120 g + NPK compound fertilizer 120 g;Topdressing compound fertilizer in the second year: NPK compound fertilizer 150 g + urea 150 g fertilization. The Eucalyptus plantation grows best under above mode. The tree height,DBH and single volume of the 2. 5-year-old stand can reach 17. 10 m,12. 80 cm,and 0. 138 m~3,respectively.
