摘要:

【目的】 研究不同磷肥用量条件下有机物料添加的棉田综合效益,为棉田磷肥用量提供理论和技术参考。【方法】 采用大田试验方法,设置有机物料添加(有机酸、有机肥、生物炭)×不同磷肥用量(0、50、100和150 kgP2O5/hm2)双因素试验处理,利用雷达图分析法,从棉花产量、经济收益、磷肥利用率、土壤磷素有效性、土壤微生物指标(碱性酸酶活性、微生物生物量)等,综合性评价不同处理2020年棉田效益。【结果】 根据向量综合评价函数,MAP0+CK、MAP50+CK、MAP100+CK、MAP150+CK、MAP0+OF、MAP50+OF、MAP100+OF、MAP150+OF、MAP0+OA、MAP50+OA、MAP100+OA、MAP150+OA、MAP0+BC、MAP50+BC、MAP100+BC、MAP150+BC的综合评价值为0.609 9、0.896 7、0.921 5、0.913 3、0.610 3、0.832 7、0.998 8、0.903 5、0.636 6、0.937 8、0.916 3、0.783 9、0.765 4、0.941 1、0.945 2、0.875 3。【结论】 磷肥(100 kgP2O5/hm2)配施有机肥调控是棉田最优的施肥用量,而其中在100 kgP2O5/hm2的磷肥用量为梯度最优,添加有机酸调控的为50 kgP2O5/hm2+有机酸处理最优,添加生物炭调控的为100 kgP2O5/hm2+生物炭处理最优,添加有机肥调控的为100 kgP2O5/hm2+有机肥处理最优;在合理的磷肥用量条件下,增施有机物料可提高综合效益。

Abstract:

【Objective】 In order to clarify the comprehensive benefits of cotton fields added with organic materials under different amounts of phosphorus fertilizer. This experiment provides theoretical and technical reference for establishing scientific fertilizer dosage and providing phosphate fertilizer dosage in cotton field.【Methods】 Using the field test method, Different amounts of organic material added (organic acid, organic fertilizer, biochar) ( kgP2O5/hm2, 50 kgP2O5/hm2, 100 kgP2O5/hm2, 150 kgP2O5/hm2) Dual-factor test treatment, Using the radar map analysis method, In terms of cotton yield, economic benefits, phosphate fertilizer utilization rate, soil phosphate effectiveness, soil microbial indicators (alkalidase activity, microbial biomass), The benefits of different treated cotton fields in 2020 were comprehensively evaluated.【Results】 According to the vector comprehensive evaluation function, MAP0 + CK, MAP50 + CK, MAP100 + CK, MAP150 + CK, MAP0 + OF, MAP50 + OF, MAP100 + OF, MAP150 + OF, MAP0 + OA, MAP50 + OA, MAP100 + OA + OA, MAP150 + O A, MAP0 + BC, MAP50+BC,MAP100 + BC, MAP150 + BC were 0.6099,0.8967,0.9215,0.9133,0.6103,0.8327,0.9988,0.9035,0.6366,0.9378,0.9163,0.7839,0.7654,0.9411,0.9452,0.8753.【Conclusion】 Comprehensive analysis believes that a certain amount of phosphorus fertilizer (100 kgP2O5 /hm2) with organic fertilizer regulation is the optimal fertilization result of cotton fields, While the amount of phosphate fertilizer used at 100 kgP2O5 /hm2 is the gradient-optimal, For 50 kgP2O5 /hm2 + OA, Biochar-regulated 100 kgP2O5 /hm2 +BC, The addition of organic fertilizer regulation is 100 kgP2O5 /hm2 + OF is optimal; Under the reasonable amount of phosphate fertilizer used, The increased application of organic matter materials can improve the comprehensive benefits.
