摘　　要：采用田间对比试验,研究了腐殖酸与复合肥配施对白蜡生长和土壤特性的影响。两年的研究结果表明,腐殖酸与复合肥一起施用可显著促进白蜡的胸径和树高生长,较未施肥对照的增长幅度分别为119.86%和53.25%;相比之下,单施腐殖酸对树高生长的效果要优于单施复合肥,而单施复合肥则较腐殖酸更有利于胸径生长。腐殖酸与复合肥共施后,白蜡叶片的净光合速率、气孔导度和叶绿素含量均有明显提高,林地土壤肥力得到显著改善。The field experiment was carried out to study the effects of combined application of humic acid and compound fertilizer on the growth of Chinese ash and soil properties.The results showed that the co-application of humic acid and compound fertilizer significantly improved the growth of DBH（diameter at breast height）and tree height with the increase of 119.86% and 53.25%,respectively.Compared with compound fertilizer,the single application of humic acid was more beneficial for tree height of Chinese ash.However,the single application of compound fertilizer was better than humic acid to increase DBH growth.The photosynthesis rate,stomatal conductance and chlorophyll content were evidently enhanced by the co-application of humic acid and compound fertilizer,which also significantly improve the soil fertility.
