摘    要:连续2年的测试研究表明,兰州市安宁区蔬菜保护土壤盐分浓度在10~30g/kg之间,属于盐渍化土壤;土壤盐分在2个年度间差异不明显;0~20cm表层盐分浓度达到178g/kg,超过了土壤盐分浓度15g/kg的临界值,表层盐分浓度显著地高于20~80cm土体的平均值148g/kg。盐分在土壤剖面中有表聚现象。

关 键 词:保护地  土壤盐分  剖面分布

Abstract:The results during two years show that the salt contents of vegetable planted soil under plastic shed range from 1.0 to 3.0 g/kg, which indicates the soil is salt affected. There is an unremarkably difference between two years in salt content of soil. 1.78 g/kg salt content in top soil exceeds the critical value of 1.5 g/kg significantly and goes beyond that of 1.48 g/kg in middle soil 20~80 cm, this means there is a surface cumulating of salts on profile.
Keywords:soil under plastic shed  salt content  profile distribution
