摘要
基于临沂市第二次土壤普查(20世纪80年代)及国家测土配方施肥项目土壤调查数据,按照土壤类型和种植制度划分,系统研究了临沂市耕作土壤pH值变化特征,并对引起土壤酸化的原因进行了探讨和分析。
Based on the 1980s＇ soil inventory data and the survey results of national soil testing and formulated fertilization project in Linyi city,the changing tendency of soil pH value was studied systematically under major soil types and cropping systems.The reasons of soil acidification were also analyzed.
