土壤盐分测定方法较多,其中电导法是土壤可溶性盐分测定的主要方法之一,方法准确,但由于传统方法只能在借助于实验室一系列设备的条件下进行,需要提取土壤的滤清液,时间相对比较长,很难应用于棉田盐分的动态监测,也不利于大样本作业棉田实地测量;而且随着土壤取样离地时间的延 Soil salt measurement methods are more, of which the conductivity method is one of the main methods of determination of soil soluble salt, the method is accurate, but because the traditional method can only be carried out by means of a series of laboratory equipment, the need to extract the soil filtrate , The time is relatively long, it is difficult to apply to the dynamic monitoring of salt in cotton field, but also not conducive to field measurement of large samples of cotton field; and with the extension of soil sampling time
