| Abstract: | Due to drought and water shortage,and overgrazing,etc.,stalinization of grassland has turned worse year after year in Songnen Plain.Comprehensive productivity and ecological environment suffered the threat,which influenced regional economic development and the standard of living.This paper adopted PPC model based on RAGA,took soil chemistry,physics,biology,environment and benefit as evaluation indexes,evaluated the integrated technology,fence rearing,shallow scarify and slight harrow.The results showed that the integraed technology was scientific,effective and practical and had higher value in the agricultural production of the region. |
| Keywords: | saline-alkali grassland vibrating deeply-loosening improvement method index evaluation |
