摘要
本文选用猪粪与玉米秸秆为原料,研究了碳氮比对猪粪-玉米秸秆混合堆肥的影响,比较堆肥过程中堆体各项指标的差异,根据T值和种子发芽指数进一步评价腐熟度,结果表明,C/N值为20时处理腐熟效果最好。堆肥结束后,猪粪-玉米秸秆混合物中的重金属含量显著增加,但均符合《有机肥料》(NY525-2012)标准限量要求,可以作为肥料施用。
In this paper, pig manure and corn stover were used as raw materials. The effects of carbon to nitrogen ratio on pig manure-corn straw mixed compost were studied, the differences of various indexes in the composting process were compared, and the degree of maturity was further evaluated according to T value and seed germination index. The results showed that the best decomposing effect was obtained when the C/N value was 20. After the composting, the heavy metal content in the pig manure-corn straw mixture increased significantly, but all met the standard requirements of Organic Fertilizer （NY525-2012） and could be applied as fertilizer.
