Effect of sewage sludge compound fertilizer on yield and qualities of flowering Chinese cabbage

大田试验研究以城镇污水处理厂污泥为原料制作的复混肥在菜心上的使用效果,结果表明施用污泥复混肥(14-6-8)有显著的增产效果,比等氮磷钾总量的商品复混肥增产25.5%,比等氮磷钾总量的15-15-15处理增产20.6%,比等氮、磷、钾含量的单质混合肥增产9.5%;具有增加地上部产量和商品产量、提高商品率和N、K养分含量的效果,不同肥料处理主要重金属的含量变化差异不明显。

The effects of sewage sludge compound fertilizer applied on flowering Chinese cabbage（Brassica campestris L.） indicated that the application of SSCF had extreme yield-increased effect compared with the other fertilizers treatment,with the scopes of 9.5% ～25.5%.The application of SSCF could improve the quality of farm product,promote the absorption and utilization of N,P2O5 and K2O,has no obviously affection on heavy metals content of the above-ground of flowering Chinese cabbage.
