英文摘要	The partial substitution of mineral phosphorus (P) fertilizer by crop straw can mitigate its consumption and losing risk to the environment. However, the changes in soil P availability, acid phosphatase (AcP) activity, and grain yield under mineral P fertilizer reduction and crop straw incorporation remain poorly understood. This study evaluated the effects of a 20% reduction in mineral P fertilizer plus maize straw addition on soil P availability, AcP activity, and maize grain yield, as well as their relationships in a 5-year continually planted maize field in northeast China. Results showed that five years of continuous 20% of mineral P fertilizer reduction and maize straw incorporation significantly increased soil NaHCO3-Po and NaOH I-Pi concentrations, and did not decrease soil labile inorganic P concentration and grain yield compared to the treatment where 100% mineral P fertilizer was applied without straw addition. Additionally, there were significant positive correlations between soil AcP activity, labile inorganic P concentration, and grain yield, indicating AcP might play an important role in maintaining soil P availability and grain yield. Overall, the addition of maize straw can effectively replace 20% of the mineral P fertilizer and could be used as an appropriate fertilization practice in northeast China.
