摘　　要：在北方寒区春季水稻大棚育苗中后期,土壤容易发生返盐现象,秧苗易发生立枯病。以往出现返盐现象和发生水稻立枯病经常用硫酸来进行调酸与防治,但近年来国家对硫酸的管控力度增强,申请购买周期长、操作难度大。在2 a的实践中,改用醋酸作为调酸剂与防治剂取得了良好的效果。In the mid-late period of rice seedling raising in greenhouse in the cold area of North China,the phenomenon of returning salt and rice bacterial wilt often occur.The climate characteristics of North China determine that it is not enough to carry out the second seedling raising and affect the transplanting time of rice.In the past,sulfuric acid was often used to regulate and control the return of salt and rice bacterial wilt.However,in recent years,the national control of sulfuric acid has been strengthened,and the application period is long and the operation is difficult.In the two years of practice,acetic acid has been used as the acid regulator and control agent with good results.
