摘　　要：为明确不同处理对大豆苗期耐盐碱能力的影响,对大豆种子采取引发剂处理、水处理和未处理三种处理方式,研究了盐碱胁迫下苗期植株K^+、Ca^(2+)和Na^+的变化。结果表明:种子引发剂处理的苗期植株,在盐碱胁迫下其地上部和地下部Na^+、K^+和Ca^(2+)含量均高于未处理和水处理;引发剂处理的TSK,Na最高,而其TSCa,Na高于水处理,低于未处理。通过混合药剂吸湿回干技术处理,可以增强大豆种子的抗盐碱性,为解决大豆耐盐碱能力提供新的理论依据。In order to study the saline-alkaline resistance effect of various treatments on the soybean seedlings, the contents of K^＋, Ca^2＋ and Na^＋ of soybean seedlings under saline-alkali stress were tested at the treatments of mixed chemicals, water, and the original seeds, respectively. The results indicated that the contents of Na^＋, K^＋, and Ca^2＋ in over-ground and under-ground of seedlings with mixed chemical treatment were higher than those of watered and original ones under the saline-alkaline stress. The mixed chemical treatment seedlings showed the highest TSK,Na among of these three treatments. Whereas, that of TSCa,Na value was higher than the watered treatments, and lower than the original treatments. The research demonstrated that it was possible to present one new theoretical application on the enhancement of soybean salt and alkali resistance by the technique of the mixed chemical treatments together with rehygroscopy-dehydration.
