Chinese Abstract

將蘭州市七裏河污水處理廠的生活污泥施用於多年生黑麥草,藉以探討施用量對黑麥草生長及其元素含量的影響。結果表明,隨著污泥施用量(0.5~8kg/m^2)的增加,黑麥草蓋度,密度,地上、地下生物量以及葉綠素含量顯著增加。施用後黑麥草地上部組織中N、P、K、Mg、Fe、Zn和Cu的含量增加,Mn含量減少,Ca和重金屬元素Hg、Ni、Pb、As含量與對照間差異不顯著,沒有對黑麥草造成重金屬毒害。

English Abstract

Sewage sludge from Qilihe sewage treatment factory, Lanzhou China, was applied for the study of the growth and element content of Lolium perenne L. by use of different quantity level in comparison with chemical fertilizer. The results showed that when the application quantity of sewage sludge was in the range of 0.5~8kg/m^2, the coverage, density, biomass of aboveground and underground of Lolium perenne L. were increased, and the chlorophyll content was increased significantly with the increase of application quantity of sewage sludge. The contents of N, P, Mg, K, Fe, Zn and Cu were increased, but Mn content was decreased, and the contents of Ca and heavy metal elements of Hg, Ni, Pb, As in aboveground biomass of that grass were no significant difference when compared with that of the control treatment. The heavy metal elements contents in he aboveground biomass were not more than the average concentration in whole plant, so the application of sewage sludge did not cause the injury on Lolium perenne L.
