1989～1991年春季将18种果树苗木栽植于盛有脱盐土的盆中,6月中旬加盐处理,使土壤含盐量分别达到0.2%、0.3%、0.4%、0.5%。结果表明,各树种出现的盐害等级与土壤含盐量及胁迫时间呈显著或极显著的正相关。根据多元回归关系,初步判定18种果树耐盐强弱顺序依次为石榴、银杏、无花果、杜梨、君迁子、枇杷、葡萄、中国樱桃、毛桃、毛樱桃、李、杏、梅、山楂、枣、板栗、猕猴桃和刺梨。 From 1989 to the spring of 1991, 18 kinds of tree seedlings were planted in pots containing desalinated soil and salt was added in mid-June to make the soil salt content reach 0.2%, 0.3%, 0.4% and 0.5% respectively. The results showed that there was a significant or highly significant positive correlation between the salt damage level of each tree species and soil salinity and stress time. According to the multiple regression relationship, the order of salt tolerance of 18 species of fruit trees was preliminarily determined as follows: pomegranate, gingko, fig, pita, junjunzi, loquat, grape, Chinese cherry, Jujube, chestnut, kiwi and prickly pear.
