摘要: 以水稻秸秆为供试物料,利用鸡粪调节碳氮比,按照干秸秆质量的30%添加磷石膏,探究磷石膏对秸秆+鸡粪堆肥进程的影响以及堆肥产物对土壤的改良作用。结果表明,堆肥对秸秆和磷石膏具有显著的腐解和崩解作用,添加磷石膏后堆体高温期符合堆肥无害化的要求,同时提高堆肥后期的温度稳定性,堆肥结束时种子发芽指数达106.77%。堆肥产物在土壤中的应用效果显示,与不加磷石膏的秸秆+鸡粪堆肥产物相比,添加磷石膏的堆肥产物增加了土壤的饱和含水量、田间持水量、电导率和有效磷含量。从肥料化角度,磷石膏+秸秆+鸡粪的联合堆肥具有改良土壤的潜力。

Abstract: Rice straw was used as the main raw composting material and chicken manure was used to adjust the ratio of carbon to nitrogen, then 30% phosphogypsum according to the mass of dry straw was added to explore the effects of phosphogypsum on straw+chicken manure composting process and also the soil improvement of the compost products was investigated. The results showed that compost had significant decomposition and disintegration effects on straw and phosphogypsum. In the composting process, the duration of the high temperature period of the stack containing 30% phosphogypsum still met the requirement of harmless composting, and the temperature stability in the later stage of composting was improved. At the end of composting, the seed germination index value could reach 106.77%. The application effect of compost products in soil showed that compared with the straw+chicken manure compost product without phosphogypsum, the compost fertilizer with phosphogypsum could increase the saturated water content, field water capacity, electrical conductivity and available phosphorus content of soil. From the perspective of fertilization, the co-composting of phosphogypsum + straw + chicken manure had the potential to improve soil.

Key words: phosphogypsum, rice straw, chicken manure, co-composting, humification, soil improvement
