the way of using by-product from flue gas desulphurization to reclaim sodic soil is put forward in recent years, and the related theory for it is not perfect.
用含石膏的脱硫副产物改良堿(化)土壤是近几年提出的,其理论还不完善。
using the two assured modifying agent can hold back the sodic soil reduce alkalescence of soil increase physicochemical property of soil thereby it can achieve increasing production on rice.
studying continuous effect in improvement of heavy sodic soil with desulphurization by-product is important to obtain theories of completely improvement.
