| 摘 要： | 通过室内盆栽模拟试验,研究了10%草甘膦水剂在5种浓度下对土壤盐碱化的影响。结果表明,施药后,土壤的盐碱度(用电导率表示),钠碱化度(ESP),钠吸附比(SAR),总碱度及pH值都明显增大,且随施药次数的增加,上述各项盐碱化指标都不断的增大。虽然土壤各项盐碱化指标的变化还在非盐渍土范围内,但有盐碱化的趋势。

| Abstract: | As a sort of herbicide,glyphosate is used widely in the world.So,the effect of glyphosate on soil is highly attended.The experiment in the effect of 10% glyphosate aqueous solution with five concentrations on soil saline-alkalization was conducted through the potted plant growth.The results indicated that after glyphosate was applied,the salinity(expressed by electrical conductivity),exchangeable sodium percentage(ESP),sodium adsorption ration(SAR),alkalinity and pH value of the soil increased obviously.With the increasing of the application amount of glyphosate,all indexes mentioned above were increased.With the increasing of the concentration,all indexes were increased after the glyphosate was applied every time.Though the changes of all indexes were within the range of non-saline or non-sodic soils,the soil affected by salt in glyphosate aqueous solution tended to saline-sodic soil. |
