补充资料：碱土
| 碱土 solonetz 土壤胶体中含交换性钠较多（碱化度达15％或20％)的土壤。其主要特征是：呈强碱性反应（pH8.5～11）；胶体高度分散，干时收缩坚硬板结，湿时膨胀泥泞；结构性差 ，通透性不良；含盐量不高。主要分布于世界各大洲的内陆干旱、半干旱地区，常与盐土相伴存在。中国的东北、华北和西北地区多以斑块状零星分布于盐土中间。碱土因土壤胶体在吸附土壤溶液中钠离子的同时不断交换出钙、镁离子，从而使胶体中交换性钠的百分率增大。中国境内的碱土分3个亚类：①草甸碱土。多见于松辽平原和黄淮海平原，地下水较浅，土壤有轻微的季节性积盐。②草原碱土。主要在大兴安岭以西的高原草原地区，已脱离地下水影响，有明显的柱状、棱柱状碱化层。③龟裂碱土。不受地下水影响，地表因干旱呈龟裂状，几乎不能生长植物，主要在新疆、甘肃、宁夏等地的荒漠和半荒漠地带。碱土改良的中心任务是降低交换性钠的含量。施用石膏、磷石膏和氯化钙等物质，以其中的钙离子交换出碱土中的钠离子，使之随雨水和灌溉水排出土壤；施用硫磺、硫酸亚铁等酸性物质，中和土壤酸度，活化土壤中的钙，降低土壤中碳酸钠盐类浓度，提高某些矿质营养元素对植物的有效性。化学措施须与水利、农业措施相配合。
