摘　　要：以新疆氯化物强盐碱土为研究对象,观察通过施加棉秆热解产物对其特性的影响。棉秆热解产物为木醋液和棉秆炭,棉秆炭结合牛粪制取炭肥混合物。采用不同添加剂的单因素和正交试验,将木醋液和棉秆炭肥施用到氯化物强盐碱土,进行室内微域培养。通过对盐碱土特征值酸碱度(p H)、盐分(c)、碱化度(ESP)、钠吸附比(SAR)的测定,采用单因素趋势线和熵值法进行综合评分与方差分析,得出p H,c,SAR和ESP改变量分别为0.29,2.84 g/kg,2.5 mmol/L和7.80;显著作用参数:木醋液为稀释1 200倍,炭肥为10 g。研究结果为棉田盐碱化土壤的改性和农业剩余物热解产物的推广应用提供依据。Cotton pyrolysis products are wood vinegar and cotton charcoal. Cotton carbon combined with cow dung gets carbon fertilizer mixture. Using different additives of single factor and orthogonal experiment, strong chlorine saline soil with wood vinegar and cotton carbon fertilizer was cultured in indoor micro field. p H（p H）, salinity（c）, alkalinity（ESP）, sodium adsorption ratio（SAR） were measured and analyzed that single factor trend line and entropy method do comprehensive evaluation and variance analysis. The p H, c, SAR and ESP change quantity were 0.29, 2.84 g/kg, 2.5 mmol/L and7.80 respectively, significant interaction parameters of wood vinegar and carbon fertilize were diluted 1200 and 10 g. The research results provide the basis for the cotton field soil modification and agricultural residues of pyrolysis products application.
