摘要
[目的]研究城市生活污水厂污泥对生菜(Lactuca sativa var. ramose)、白菜(Brassica pekinensis)和番茄(Lycopersicon esculentum)种子发芽率的影响。[方法]通过盆栽试验,测量污泥施用量对生菜、白菜和番茄的种子发芽率的影响。[结果]随着污泥施用量的增加,生菜、白菜和番茄种子发芽率降低。[结论]污泥对生菜、白菜和番茄的发芽率有明显的抑制作用。
[ Objective ] To explore the effect of urban sewage sludge on the germination rate of Lactuca sativa var. ramose, Brassica pekinensis and Lycopersicon esculentum. [ Method ] A pot experiment is conducted to measure the effect of sludge application quantity on germination rate of Chinese lettuce, cabbage and tomato. [ Result] With the increase of sludge application quantity, the seed germination rate of Chinese let- tuce, cabbage and tomato decreased. [ Conclusion ] Germination rate of Chinese lettuce, cabbage and tomato is obviously inhibited by sludge.
