摘　　要：应用非金属矿物沸石(尿素沸石)、白云石改良皖南地区酸性红黄壤,结果表明:盆栽玉米、大豆植株干物重增加39.4%-54.5%,NPK吸收量增加25.7%-52.7%;大田试验玉米产量增加23.5%,NPK吸收量增加8.2%-30.6%。沸石(尿素沸石)与白云石配合效果好,是改良酸性红黄壤有效途经。Effect of nonmetal mineral zeoloite (urea zeolite) and dolomite on amelioration of acid red - yellow soil in south of Anhui was conducted. The result shows: Cultivated in pot, maize and soybean yield was increased by 23. 5% . The application of zeolite (urea zeolite) combined with dolomite was best in terms of crop yied and soil amelioration.
