摘　　要：本研究采用不同浓度ＮａＣｌ进行水稻、大豆土培试验。结果表明：低浓度ＮａＣｌ对水稻、大豆的生育有一定的促进作用，超过一定浓度便产生危害，生育受阻，产量降低。当土壤ＮａＣｌ含量为１５００ｍｇ／ｋｇ时，水稻减产１４．６％；为１０００ｍｇ／ｋｇ时，大豆减产１７．１％。The effects of NaCl of different concentrations on rice soybean were tested in field.The results showed:NaCl of low concentration would promote the growth of rice and soybean.But when its concentration increased to a certain extent it would hinder their growth and reducetheir vield.When the NaCl in the soil was 1 500 mg/kg,the yield of rice reduced by 14.6%;When it was 1 000 mg/kg,the yield of soybean reduced by 17.1%.
