城市污水污泥有机复合肥水稻施肥试验

Rice Fertilization Experiment of Compound Manure of Urban Sludge

城市污水处理厂污泥经好氧发酵 ,与粉煤灰、无机肥料等原料混合制成有机复合肥 ,对水稻生长进行肥效试验。结果表明 :该有机复合肥对水稻的增产效果显著 ,肥效与 N、P、K三元复合肥相当 ,值得进一步研究开发。

Sludge of urban sewage treatment plants was fermented in aerobic, and then mixed with coal ash, inorganic fertilizers to produce organic compound manure ,which was applied in fertilization trial of paddy rice.This compound manure could fairly raise the output of paddy in the trail, and as good as N, P, K fertilizers used.
