为了探究生物炭的不同粒径对猪粪好氧堆肥中堆体养分变化的影响,以猪粪和稻草秸秆为堆肥原料,分别添加0.15(F1)、4.00(F2)、20.00(F3)mm粒径的生物炭进行好氧堆肥(未添加生物炭为处理F4),测定了堆肥过程中不同粒径生物炭堆体理化性质、养分形态及含量,并结合扫描电镜和傅里叶红外光谱分析其机理.结果表明:F1、F2和F3比F4提前进入高温期,F1处理组比F2和F3处理组提前2 d进入高温期,比F4处理组提前3 d进入高温期,其中F2处理组高温停留天数最久;F1、F2和F3处理组与F4处理组相比堆体pH含量增加;F1、F2和F3可降低堆肥盐渍化风险,F3处理组降低堆肥盐渍化效果最好;堆肥过程中F1、F2、F3和F4含水率分别下降了58.57%、52.23%、66.18%、60.90%,有机质含量分别减少了45.33%、42.46%、42.97%、46.67%,F1、F2和F3可有效减少NH3的挥发;在堆肥结束时F1、F2、F3和F4比初始全氮提高46.08%、41.21%、35.70%、26.28%,硝态氮含量提高 6.45%、9.37%、6.25%、3.22%,全钾含量提高 33.21%、33.05%、33.67%、25.83%,全磷含量提高60.82%、66.62%、102.6%、57.51%.综合分析,0.15 mm生物炭与猪粪堆肥可有效提高堆体氮素含量,因此,0.15 mm的生物炭可作为提高堆肥氮素的优质粒径.
In order to explore the effect of different particle sizes of biochar on the nutrient changes of pig manureaerobic composting,pig manure and rice straw were used as composting materials,and biochar with particle sizes of 0.15,4.00 and 20.00 mm was added for aerobic composting.The physical and chemical properties,nutrient forms and contents of biochar with different particle sizes during composting were determined,and the mechanism was analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy.The results showed that F1,F2 and F3 entered the high temperature period earlier than F4.The F1 treatment group entered the high temperature period 2 days earlier than the F2 and F3 treatment groups,and entered the high temperature period 3 days earlier than the F4 treatment group.The pH content of F1,F2 and F3 treatment groups increased compared with F4 treatment group.F1,F2 and F3 could reduce the risk of composting salinization,and F3 treatment group had the best effect on reducing composting salinization.The moisture content of F1,F2,F3 and F4 decreased by 58.57%,52.23%,66.18%and 60.90%,respectively.The organic matter content decreased by 45.33%,42.46%,42.97%and 46.67%,respectively.F1,F2 and F3 can effectively reduce the volatilization of NH3.At the end of composting,F1,F2,F3 and F4 increased by 46.08%,41.21%,35.70%and 26.28%compared with the initial total nitrogen.The nitrate nitrogen content increased by 6.45%,9.37%,6.25%and 3.22%,and the total potassium content increased by 33.21%,33.05%,33.67%and 25.83%.The total phosphorus content increased by 60.82%,66.62%,102.6%and 57.51%.Comprehensive analysis showed that 0.15 mm biochar and pig manure compost could effectively increase the nitrogen content of the compost.Therefore,0.15 mm biochar could be used as a high-quality particle size to increase the nitrogen content of compost.
