城市固体废弃物堆肥与化肥对不同土壤植物生长的影响研究

温室盆栽试验研究城市固体废弃物堆肥与化肥对不同土壤黑麦草生长的影响,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种土壤处理C50干物质产量分别比对照增加39.53%和109.38%,而NPK处理则分别增产267.44%和406.25%。堆肥与化肥配施处理(NPK C25对阳春和NPK C50对大安)产量最高。堆肥处理明显增加土壤pH、有机碳、土壤有效态磷、钾、铁、锰、锌和铜含量。

Effects of municipal solid waste compost and chemical fertilizer on plant growth in different soils

A pot experiment was conducted to compare the effects of municipal solid waste compost and chemical fertilizer on the growth of ryegrass(Lolium perenne L.) in different soils.The results show that the compost and chemical fertilizer significantly increase the dry matter production of ryegrass.The application of 50t/hm~2 of compost alone increases the dry matter yield by 39.53% and 109.38%,while that of chemical NPK alone,by 267.44% and 406.25% for Yangchun and Da'an soils,respectively.The combination of compost and chemical NPK(NPK C_(25) for Yangchun and NPK C_(50) for(Da'an)) shows the highest crop yields.The contents of soil organic carbon,available P,K,Fe,Mn,Zn,Cu,and pH are obviously increased after the treatment with compost.
