　　以城市污泥为试验材料，以沙地主要造林树种彰武小钻杨（Populus×xiaozhuanica W．Y．Hsu et Liang‘Zangwu’）为研究对象，利用田间试验，分别设置不同剂量的城市污泥（以造林植苗穴的体积为基准，V（污泥）∶V （沙土）＝1∶1、V（污泥）∶V（沙土）＝3∶4、V（污泥）∶V（沙土）＝1∶2、V（污泥）∶V（沙土）＝1∶3、V（污泥）∶V （沙土）＝1∶4、V（污泥）∶V（沙土）＝1∶5、V（污泥）∶V（沙土）＝0∶1，分别记为C6、C5、C4、C3、C2、C1、C0，其中C0为不施污泥，为对照）进行处理。结果表明：增加污泥施用剂量提高了沙地彰武小钻杨杨树苗木的成活率，经C6、C5、C4、C3、C2、C1污泥处理的分别比对照处理的苗木成活率提高了31．74％、28．99％、9．78％、7．03％、4．29％和1．55％；经C6、C5、C4、C3、C2、C1污泥处理与对照组相比，显著地促进了杨树幼苗的树高、胸径和叶面积的生长，有利地促进幼苗对养分的吸收；经C6、C5、C4、C3、C2、C1污泥处理的杨树叶子含氮和叶绿素质量分数显著地高于对照组幼苗，进而提高了杨树幼苗的光合作用能力；经C6、C5、C4、C3、C2、C1污泥处理的杨树幼苗与对照组相比，显著增强了光合速率。综上所述，经C5污泥处理的苗木表现最佳。

Taking the northern sewage treatment plant sludge as the experimental material, by thefield trials , we set municipal sewage sludge levels with the amount of sewage sludge (the hole size as a benchmark sludge/sand by volume, 1 ∶0, 1 ∶1, 3 ∶4, 1 ∶2, 1 ∶3 , 1 ∶4, 1 ∶5, 0 ∶1, respectively, denoted C7, C6, C5, C4, C3, C2, C1, C0 for processing, and C0 is not applied sludge as a control.C6, C5, C4, C3, C2 and C1 sludge treatments significantly enhanced more survival rate of seedlings than that of the controlled seedlings by 31.74%, 28.99%, 9.78%, 7.03%, 4.29%and 1.55%, re-spectively.C6, C5, C4, C3, C2 and C1 sludge treatments significantly promoted the average individual heights, diameter and leaf area of seedlings compared to those of the controlled seedlings, and accelerated the absorption of main plant nutri-ents.C 6, C5, C4, C3, C2 and C1 sludge treatments significantly enhanced the leaf nitrogen contents and chlorophyll con-tent of seedlings compared to those of the controlled seedlings, and thereby, raised the photosynthetic capacity of polar seedlings.C6, C5, C4, C3, C2 and C1 sludge treatments significantly enhanced the photosynthetic rate of seedlings com-pared to those of the controlled seedlings.In summary, C5 sludge treatment was optimum in all.
