摘要
将城市污水污泥经过一次好氧堆肥发酵和二次厌氧堆肥发酵后 ,适当添加营养成分制成甘蔗专用复合肥 ,其肥效成分为w (N) 1 4 3% ,w (P2 O5) 4 % ,w (K2 O) 5%。田间试验表明 :( 1 )施用不同肥料对甘蔗出苗数、有效茎数和甘蔗糖分影响较小 ;( 2 )污泥有机复合肥施用量不同甘蔗的产量也不同 ,在甘蔗田每hm2 施用 2 4 0 0kg污泥有机复合肥比较合适 ;( 3)当有机复合肥施用量为 2 4 0 0kg/hm2 时 ,污泥有机复合肥肥效明显优于市场上出售的三元复合肥和由尿素。
The sludge organic complex fertilizer (SOCF) for sugarcane, which contains 14 3% of nitrogen, 4% of phosphorus oxide and 5% of potassium oxide, is made from municipal sludge after aerobic and anaerobic fermentation by adding nitrogen, phosphorus and potassium properly. Field experiments show that: (1) Various fertilizers have a very weak influence on the emergence rate, effective stem and sugar rate of sugarcane; (2) The output of sugarcane varies with the amount of SOCF applied in field and it is optimum ...
