摘要
测定土壤中可溶性盐分有不同的方法,残渣烘干法为经典法,适用于不同土壤;阴阳离子总和测定法误差稍大,操作较繁;电导法-标准曲线法如果标准样品少,精确度达不到要求;刮盐皮—标准曲线法有较好的实用性,在一定地域内可以进行土壤可溶性盐分的快速测定,精确度准确可靠。
Methods were available to detect the content of soil dissoluble salt, such as the method of remainder dry, the summation of negative ion and positive ion, electroconductance-standard curve and salt curve and salt curst-standard curve. The classic remainder dry method could be applicable to kinds of soil ; the summation of negative ion and positive ion was slightly low precise and laborious ; if standard samples were not enough, the accuracy of electroconductance-standard curve could be unaccepted ; the method of salt crust-standard curve was, for a given region, more practical and efective.
