| 摘 要： | 目的]研究城市污水厂污泥对白菜生长的影响。方法]通过盆栽试验，测量污泥施用量对白菜种子发芽率和苗期生长的影响；通过田闯试验，测量污泥施用量对白菜生长的影响。结果]污泥的施用量小于6．4kg/hm^2时，对白菜发芽率的影响不大；苗期白菜的平均株高和平均地上部鲜重都随着污泥用量的增加而增加。田间种植白菜的平均株高、平均鲜重和平均地上部分鲜重，先随污泥的用量增加而增加，当污泥的施用量为2．0kg/m^2时，株高、平均鲜重和平均地上部分鲜重达到最高值；污泥的用量再增加时，株高、平均鲜重和平均地上部分鲜重逐渐下降。结论]污泥施用量对白菜的生长有影响。

| Abstract: | Objective] The research aimed to explore the effect of sewage sludge on the growth of Chines cabbage.Method] A pot experiment was adopted to study the effect of sewage sludge on germination rate and seedling growth of cabbage.A field experiment was carried out to evaluate the effect of sewage sludge on growth of cabbage.Result] In pot experiment,when the application was less than 6.4 kg/m2,the seed germination rate of cabbage was not influenced observably.The average height and aboveground fresh weight w... |
