摘要
[目的]研究不同肥料对土壤物理特性和棉花产量的影响,为提高棉花产质量提供理论参考。[方法]以鲁种棉169为材料,连续2年进行定位试验。设置3个不同处理(①施用常规水溶肥,处理②施用棉粕腐殖酸肥,处理③为空白处理(CK)),研究3种处理条件下的土壤容重、肥料农学利用效率和棉花产量。[结果]各处理条件下棉田土壤容重均有所降低,土壤孔隙度均有不同程度的增加,其中处理②的容重降低了7.29%,孔隙度增加了9.00%,改善土壤物理性质的效果最好。同时处理②的肥料农学利用效率显著高于其他处理,增产效果最明显。[结论]施用棉粕腐殖酸肥可以有效改善棉田土壤的物理性质,提高农学利用效率和棉花产量,值得推广应用。
[Objective]To study the effects of different fertilizers on soil physical properties and cotton yield,and provide a theoretical reference for improving cotton yield and quality.[Method]Taking the Lu cotton 169 as an example,the positioning test was carried out for 2 consecutive years.3 different treatments(treatment①conventional water-soluble fertilizer,treatment②cotton aphid humic acid fertilizer,and treatment③blank treatment(CK))were set up,and soil and bulk density,fertilizer agronomic efficiency and cotton yield under three treatment conditions were analyzed.[Result]The soil bulk density of cotton fields decreased under various treatment conditions,and soil porosity increased to varying degrees,the bulk density of treatment②was reduced by 7.29%,and the porosity was increased by 9.00%,so the effect of improving soil physical properties was best.At the same time,the agronomic utilization efficiency of treatment②was significantly higher than other treatments,and the yield increase effect was also the most obvious.[Conclusion]Application of cotton aphid humic acid fertilizer can effectively improve the physical properties of cotton field soil,improve agronomic utilization efficiency and increase cotton yield,which is worthy of popularization and application.
