摘　　要：在田间条件下研究不同生物肥料配比:全有机肥、半有机肥,半有机肥+半无机肥、全无机肥等处理对盐碱土的改良效果。结果表明,全有机肥处理与半有机肥+半无机肥处理对盐碱土改良效果明显,而全无机肥处理对改良盐碱土几乎无影响;生物有机肥能够降低盐碱土pH,增加土壤有机质含量,减缓土壤碱解氮、有效磷的消耗,显著提高速效钾含量,降低土壤盐分,提高土壤阳离子含量,降低土壤碱化度。Under field conditions, the saline-alkali soil improvement by different ratio of biological fertilizers： whole organic fertilizer, half organic fertilizer, half organic＋half inorganic fertilizer, whole inorganic fertilizer were researched in the study. The results showed that the improvement effects on saline-alkali soil by whole organic fertilizer treatment and half organic mixed with half inorganic fertilizer treatment were significant; while inorganic fertilizer treatment had almost no improvement effect on saline-alkali soil; bio-organic fertilizer could reduce the pH of saline-alkali soil, increase soil organic matter content, slow down the soil alkali-hydrolyzed nitrogen and available phosphorus consumption, increase available potassium, content, increase the cation content of soil, reduce soil degree of alkalization.
