用CaCl2 和CuCl2 液浸提施入堆肥培养后的土壤.结果表明,有机碳随堆肥用量增加而增加;NO-3 - N 在堆肥用量0 .1 % ～1 .0 % 时无明显变化,在5 % ～10 % 时增加;钾随堆肥用量增加而增加.堆肥的施入未引起土壤磷素明显变化.
The results showed that the content of organic carbon increased with the increase of compost dosage; NO-3 - N did not change obviously when the compost dosage was from 0.1% to 1.0% 5% ~ 10% increase; potassium increased with the increase of compost dosage.Compound application did not cause significant change of soil phosphorus.
