摘　　要：[目的]探明有机酸添加对不同磷肥用量新疆棉田磷素健康状况的综合评价。[方法]采用大田试验方法,在不同磷肥用量处理(0、50、100、150kg P2O5/hm^(2))的基础上,设置对照(CK)和有机酸添加(OA)处理。研究2019—2020年棉田土壤速效磷、微生物生物量磷、碱性磷酸酶活性、植株生物量、植株吸磷量、籽棉产量、经济效益、植物磷素盈余量8个向量指标进行基于雷达图分析的新疆棉田磷素健康综合评价。[结果]有机酸添加对不同磷肥用量新疆棉田磷素健康状况评价结果分别为0.254 5、0.381 3、0.390 4、0.390 2、0.406 5、0.437 2、0.394 0、0.395 1,最终排序为MAP100+OA>MAP100+CK>MAP150+OA> MAP150+CK>MAP50+CK>MAP50+OA>MAP0+OA>MAP0+CK。[结论]45 kg有机酸+100 kg P_(2)O_(5)/hm^(2)处理是新疆棉田磷素健康管理的最优处理,可为新疆棉田磷素健康状况评价提供一个更为客观和科学的参考。[Objective]To explore the comprehensive effect of organic acid addition on phosphorus health status of cotton field in Xinjiang with different phosphorus fertilizer dosage.[Method]Field experiment method was adopted.The control(CK)and organic acid addition(OA)treatments were set on the basis of different P fertilizer dosage(0,50,100,150 kg P 2O 5/hm^(2)).The comprehensive evaluation of phosphorus health in cotton field in Xinjiang was carried out based on radar chart analysis in 2019-2020 by studying eight vector indexes including soil available phosphorus,microbial biomass phosphorus,alkaline phosphatase activity,plant biomass,plant phosphorus uptake,seed cotton yield,economic benefit and plant phosphorus surplus.[Result]The evaluation results of organic acid addition on phosphorus health status of cotton field in Xinjiang with different phosphorus fertilizer dosage were 0.2545,0.3813,0.3904,0.3902,0.4065,0.4372,0.3940,0.3951,respectively.The final sequence was MAP100+OA>MAP100+CK>MAP150+OA>MAP150+CK>MAP50+CK>MAP50+OA>MAP0+OA>MAP0+CK.[Conclusion]The treatment of 45 kg organic acid+100 kg P_(2)O_(5)/hm^(2) is the best treatment for phosphorus health evaluation of cotton fields in Xinjiang,providing a more objective and scientific method for phosphorus health evaluation of cotton fields in Xinjiang.
