摘　　要：通过对盐碱化草地土壤施用0(CK),100,300,500和700 g·kg^(-1)土壤的醋糟,并分析碱地风毛菊(Saussurea runcinata)的生长及种植前后土壤性质的变化,以探讨醋糟对盐碱土壤的改良效果。结果表明:施用醋糟提高了碱地风毛菊的生长特性,并降低了盐碱土壤pH,ESP及CO_3^(2-)和HCO_3^-含量.增加了Na^+,K^+,Ca^(2+),Mg^(2+),Cl^-和SO_4^(2-)含量。因此,醋糟可以作为改良盐碱地的优良材料。This study was designed to determine the growing of Saussurea runcinata and the changes of chemical property in saline-alkali soil with different application rates of vinegar residues （0（CK）, 100, 300, 500 or 700 g · kg-1 soil）, to ascertain the effectiveness of vinegar residues {or saline-alkali soil. The results showed that the growing of Saussurea runcinata was enhanced by vinegar residues, and the con- tents of Na＋ , K＋ , Ca2＋ , Mg2＋ , C1- and SO2/4- of soil increased, but a decrease in pH, ESP, and the con- tents of CO2、3- and HCO;- of soil was observed. Thus, vinegar residues can be used as a good material to improve the saline-alkali soil.
