Abstract:
The flooding disaster in 1998 resulted in wind-sand soil scoured，deposited and long-term eroded in western of Songnen plain，and the yield of medium and low areas became further lower.This study research on different eroded sand soil located，in order to state the dynamics of the soil physical and chemical properties and nutrient sink.The wind-sand soil eroded by flooding disaster in Heilongjiang Songnen plain is classified into three degrees：flooding light，flooding middle and flooding heavily.Located trial was made in three places for three years，and results suggested that organic fertilizer can improve the status of soil water，water retaining capacity，aggregate structure，soil nutrient and soluble salt，at the same time，fertilizer measures can change the soybean yield and quality.We put forward the measures of using chemical fertilizer with bio-organic fertilizer，straw organic fertilizer，poultry dung manure to improve the fertility of water erotion land.The better system of water erosion land fertilization of wind-sand soil have set in the west part of Songnen Plain.
