摘要
以小麦秸秆为原料,在300℃和600℃下制备了2种生物质炭(BC300和BC600),考察了生物质炭添加到土壤后对土壤微孔结构的影响,研究结果表明,在土壤中添加1%的BC300和BC600,土壤的总比表面积由(5.4±0.06)m2/g分别增加到(6.7±0.08)m2/g和(7.7±0.08)m2/g,总孔容由(14.9±0.42)μL/g分别增加到(18.6±0.34)μL/g和(17.2±0.31)μL/g,平均孔径由(13.8±0.38)nm分别降低到(11.1±0.21)nm和(9.0±0.19)nm。
Bio-char was derived from wheat straw,under 300 ℃ and 600 ℃,named as BC300 and BC600,respectively,and the changes of soil surface structure was examined after bio-char was added into the soil. The results showed that after1%（weight percentage）addition of BC300 and BC600 into the soil,specific surface area increased from（5.4±0.06）m2/g to（6.7±0.08）m2/g and（7.7±0.08）m2/g respectively,and the total pore volume from（14.9±0.42）μL/g to （18.6±0.34）μL/g and（17.2±0.31） μL/g respectively,however,the average pore size reduced from（13.8 ±0.38） nm to（11.1 ±0.21） nm and（9.0±0.19）nm respectively.
