The high soil salinity is one of the important factors of restricting in sugar beet planting production in Xinjiang. The effect of amendments in saline soil was studied to make clear the influence of chemical modification agent on the salt alkali soil in Xinjiang,and provide for the rational amendment product.Four kinds of chemical amendments were choose,including acidalkali balance agent(AABA),acid enrichment agent(AEA),peptide nitrogen(PN),biological organic bacterial manure(BOBM).And five indexes,such as soil salt content,pH,sodium adsorption,total alkalinity,alkalization degree index were analyzed under different treatments.The results showed that compared with the control, soil pH applied with AABA and BOBM reduced by 0.67 and 1.03 units respectively,reached significant level(P<0.05).Excepting AEA treatment,the soil salt contents decreased for the other three kinds of modifier,applying biobacterial manure decreased soil salt by 1.19 g/kg,which reached significant level(P<0.05).The contents of CO2-3 and HCO-3 decreased by 2.00% ~ 80.00% with application of soil amendments,AABA and PN mainly reduced CO2-3,the content of CO2-3 was reduced by 49.50% and 3000% respectively.AEA reduced more HCO-3 than CO2-3.BOBM decreased both HCO-3 and CO2-3significantly by 60.40% and 80.00% respectively.All the four kinds of saline soil conditioner effectively reduced the soil total alkalinity and pH value in the top layer,and the effect of BOBM was the most significant.PN and BOBM also reduced soil sodium adsorption ratio and alkalization degree,and improved sugar beet production.AEA and AABA had no significant effect on sugar beet yield.
