为探讨有机肥对行道树悬铃木土壤肥力的影响，采用完全随机区组试验设计研究2类有机肥不同处理下，中型行道树悬铃木土壤矿质元素含量和微生物数量变化情况以及两者之间的相关性。结果表明：在有机肥不同处理下，土壤中细菌、真菌、放线菌的数量显著增加，以 TM10－2（有机肥田美乐，每株施用10 mL，共施用2次）效果最佳，且 TM系列处理能够明显控制真菌数量；各处理能够显著提高土壤矿质元素的含量，其中 TM10－1（有机肥田美乐，每株施用10 mL，共施用1次）和 TM10－2能够显著提高土壤中大量元素的含量，而各处理对土壤中交换性钙和镁含量的影响不显著，但 TM系列处理能够优化 Ca：Mg 值；总体上，TM系列在提高土壤有效铜、铁、锰含量方面的作用优于 Z（真根有机肥）系列；相关分析表明，大量元素与细菌数量极显著相关，微量元素与放线菌数量的相关性显著，而两者与真菌数量的相关性均不显著。因此，对城市行道树土壤施肥，能显著改善土壤肥力，TM肥可作为城市行道树优先推用的有机肥，且以每株施用10 mL，施肥2次效果较好。
為探討有機肥對行道樹懸鈴木土壤肥力的影響，採用完全隨機區組試驗設計研究2類有機肥不同處理下，中型行道樹懸鈴木土壤礦質元素含量和微生物數量變化情況以及兩者之間的相關性。結果錶明：在有機肥不同處理下，土壤中細菌、真菌、放線菌的數量顯著增加，以 TM10－2（有機肥田美樂，每株施用10 mL，共施用2次）效果最佳，且 TM繫列處理能夠明顯控製真菌數量；各處理能夠顯著提高土壤礦質元素的含量，其中 TM10－1（有機肥田美樂，每株施用10 mL，共施用1次）和 TM10－2能夠顯著提高土壤中大量元素的含量，而各處理對土壤中交換性鈣和鎂含量的影響不顯著，但 TM繫列處理能夠優化 Ca：Mg 值；總體上，TM繫列在提高土壤有效銅、鐵、錳含量方麵的作用優于 Z（真根有機肥）繫列；相關分析錶明，大量元素與細菌數量極顯著相關，微量元素與放線菌數量的相關性顯著，而兩者與真菌數量的相關性均不顯著。因此，對城市行道樹土壤施肥，能顯著改善土壤肥力，TM肥可作為城市行道樹優先推用的有機肥，且以每株施用10 mL，施肥2次效果較好。

In order to investigate the effect of organic fertilizer on soil fertility of sycamore trees,this article studied the change of the content of mineral elements of middle size sycamore and microbial quantity of the soil with different treatments of two kinds of organic fertilizers which offered by complete randomized block design,and ana-lyzed the correlation between them.The results showed that:the number of bacteria,fungi,actinomycetes in the soil with the different treatments increased significantly compared to that of CK.And the treatment of TM10 -2 (Or-ganic fertilizer of Tianmeile,application of 10 mL per plant,and 2 times of application in total)was the best one a-mong its series.And the TM(Organic fertilizer of Tianmeile)treatments could significantly control the number of fungi;These treatments could significantly increase the content of soil mineral elements,and the treatments of TM10 -1 (Organic fertilizer of Tianmeile,application of 10 mL per plant,and 1 time of application in total)and TM10 -2 improved the content of macro-element in the soil obviously,while,each of the treatments had no signifi-cant effect on calcium and magnesium content in soil.However,the TMtreatment series could optimize the ratio of Ca:Mg;As a whole,the TMseries in improving available Cu,Fe,Mn content in soil displayed better than that of Z (Organic fertilizer of Zhengen)series;Correlation analysis showed that the relationship between macro-element and the amount of bacteria was extremely significant;and there existed significant correlation between the trace ele-ments and the number of actinomycetes;However,the relationship between either of the two and the amount of fun-gi were all not significant.According to the results,offering organic fertilizer to urban street trees could significantly improve the soil fertility,and TMfertilizer should be the better one for urban street trees with.And the effect of fer-tilization was better at its 10 mL per plant level plus 2 times application.
