| 摘 要： | 通过油菜盆栽试验验证城市污泥对油菜生长的影响作用。结果发现：适宜的污泥用量可显著提高盆栽油菜的生物量和根重，并有助于盆栽油菜根/冠比指标的优化；同时，污泥施用比化肥更能促进盆栽油菜对N、P、K元素的吸收，能有效提高这些营养元素的利用效率；但当污泥用量达到6g/kg土时，污泥对盆栽油菜产量提高的促进作用会明显降低。 |

| Abstract: | In order to validate the effects of city sludge on rape growth, a pot culture experiment was conducted. The results of the trial indicated that rape fresh weight and root weight have been enhanced markedly by applied city sludge, applied city sludge was beneficial to optimize rape R/S; and rape uptake of N,P,K were increased by applied city sludge. |
| Keywords: | sludgezz fresh weightzz R/Szz |
