Description
Technical field
The invention belongs to soil improvement field, relate to microorganism remediation, the microorganism on especially a kind of heavy salinized ground is former
Position restorative procedure.
Background technology
In China northeast, northwest, the arid in North China, semiarid zone, precipitation is little, and evaporation capacity is big, is dissolved in water
Salinity is easily in upper soll layer accumulation.Summer rainwater is many and concentrates, and great amount of soluble salt is seeped into lower floor with water or flows away, here it is
" desalination " season；Spring, evaporation from topsoil was strong, and the salinity in underground water rises with capillary and is gathered in upper soll layer, this
It is main " accumulation of salt in the surface soil " season.Northeast, North China, the saline-alkali soil of semiarid zone have significantly " desalination " " accumulation of salt in the surface soil " season, and western
Backlands district, owing to precipitation is little, the seasonal variety of soil salt is inconspicuous.Salt-soda soil is utilizing in the middle of process, briefly,
Light salt-soda soil, moderate saline-alkali soil and heavy saline can be divided into.PH value is wherein heavy salinizedly: more than 9.5.Now with section
The development learning a skill, should only seeing disadvantageous one side, more it should being regarded as very precious land resource, because having perhaps
