通过研究棉秆基生物炭添加量对南疆沙化土壤理化性能影响,结果表明随生物炭添加量的增大,电导增大,pH值减小;容重与饱和含水量变化趋势相反,而毛管孔隙度与田间持水量变化趋势相同;自然状态下12天内水分蒸发量基本持平,生物炭添加量越大,土壤保水性能越好。当生物炭添加量为2%时,pH值和容重最小,电导、饱和含水量和田间持水量均为最大,这对降低南疆沙化土壤盐碱性,提高土壤保水能力提供了理论数据。
Abstract：The influence of the amount of cotton-based biochar added on the physicochemical properties of desertified soil in southern Xinjiang was studied. The results indicated that with the increase of biochar,the conductance increased,while pH value decreased; The trend of bulk density of soil samples and saturated water content was opposite,while the capillary porosity was the same as that of water holding capacity in field. The moisture content in the natural state was basically flat in 12 days. The higher the amount of biochar added,the better the soil water retention performance. Therefore,when the biochar content was 2%,the pH value and bulk density were the smallest,and the conductance,saturated water content and field water holding capacity were the largest,which provides theoretical data for reducing salinity and alkalinity of desertified soil in southern Xinjiang and improving soil water holding capacity.
