摘要
采用温室盆栽试验,研究了城市固体废弃物堆肥与化肥配合施用对黑麦草生长的影响。结果表明:堆肥和化肥可明显增加黑麦草干物质产量,阳春和大安2种土壤50 t/hm2堆肥处理黑麦草干物质产量分别增加39.53%和109.38%,而NPK处理分别增加267.44%和406.25%;堆肥和化肥的配施处理(阳春土壤处理③和大安土壤处理④)产量最高;堆肥处理能明显提高土壤pH、有机碳、有效磷、钾、铁、锰、锌、铜含量。
A pot experiment was conducted to compare the effects of compost and mineral fertilization on the growth and chemical composition of ryegrass grown in two different soil and the results showed that the dry matter production of ryegrass was significantly increased in the application of the compost and mineral fertilization. The application of C50 of compost alone increased the dry matter yield for Yangchun and Daan soil by 39.53 % and 109.38 %, while mineral NPK alone, by 267.44 % and 406.25 %, respectively. The combination of compost and mineral NPK （NPK＋C25 for Da＇an and NPK＋C50 for Yangchun） showed the highest crop yield. The increases in soil organic carbon, available P, Fe, Mn, Zn, Cu, K and pH were observed in.treatments with compost.
