摘要:
为促进退化黑土的改良，采用室内模拟和盆栽试验的方式，设置5个处理，土壤中添加生物炭量分别为0，50，100，200，300 g?kg-1,每个处理设置3组重复，探究不同量生物炭添加条件下，土壤田间持水量、饱和持水量、容重、比重、孔隙度的变化。结果表明：在不同量生物炭的添加条件下，土壤的饱和持水量、田间持水量、孔隙度与生物炭用量呈现出显著正相关，土壤的容重、比重与生物炭用量呈现出显著负相关。
Abstract:
In order to promote the improvement of degraded black soil,we used indoor simulation and pot experiment,also set up five treatments.The amount of biochar added to the soil was 0,50,100,200,300 g?kg-1,three parallel processing samples were set for each processing.This study was to investigate the changes of soil field water holding capacity,saturated water holding capacity,bulk density,specific gravity and porosity under different biochar addition conditions.The results showed that:wth the addition of different amounts of biochar,the saturated water holding capacity,field water holding capacity and porosity of soil presented a significantly positive correlation with the amount of biochar,and the bulk density and specific gravity of soil presented a significantly negative correlation with the amount of biochar.
