Based on the analysis of fractal dimension of soil aggregates and soil pore in low suction range,the influence of the wheat straw,comminuted,aminated or mingled with inorganic soil amendment,on the soil structure,soil bulk density,soil porosity and characters of soil water evaporation,after mixed with the soil was studied.
利用团聚体分形维数、孔隙分形维数等指标,对比分析了秸秆在经过粉碎、氨化及与无机土壤改良剂混合3种措施处理后加入土壤对土壤团聚结构、土壤容重、孔隙度及低吸力段土壤水分蒸发特性的影响,结果表明:粉碎并氨化处理过的秸秆施入土壤后,能显著改善土壤团聚结构,减小土壤容重,增加土壤孔隙度;秸秆加入土壤中会导致处理低吸力段土壤孔隙分形维数变小,孔隙分布均匀性、连通性变差,导致土壤蒸发速率过快,而无机土壤改良剂(氢氧化铁)能有效改善土壤孔隙分布,抑制土壤蒸发,当其与秸秆混合施用时,对雨水保蓄利用效果更好。

结果表明:在范德华力等粘性力作用下,纳米二氧化硅颗粒形成团聚体,团聚体粒度随二氧化硅颗粒表面吸附水分的增多而增大;纳米二氧化硅颗粒在流化过程中,一次团聚体在流体力作用下进一步团聚形成二次团聚体;流化停止后二次团聚体解体,此时纳米二氧化硅的团聚行为与流化前无明显差异;热处理温度对纳米二氧化硅颗粒起始流化速度影响不大,但纳米二氧化硅颗粒的起始流化速度随颗粒表面能的减小而显著降低,而且颗粒的表面处理对床层塌落与膨胀行为具有重要影响。
