乌鲁木齐市再生水灌溉对棉花品质的影响

Impacts of Urumqi Reclaimed Water Irrigation on Cotton Quality

[目的]为再生水在棉花灌溉方面的安全利用提供理论依据。[方法]利用乌鲁木齐某二级污水处理厂的再生水,通过大田栽种,研究不同级别再生水浇灌对棉花品质的影响。[结果]50%的再生水浇灌减轻了再生水对棉花质量的负面影响,只有棉绒长度显著降低。[结论]50%的再生水可以替代对照水浇灌棉花,不会对棉花质量产生不利影响。

[Objective] To provide theoretical basis for popularizing safety utilization of reclaimed water in irrigation of cotton.[Method] Using reclaimed water from a secondary sewage treatment plant of Urumqi,the influence of different level reclaimed water to cotton quality was studied.[Result] The results showed that 50% reclaimed water reduce the negative impact of reclaimed water on cotton quality,and only cotton wool length was significantly decreased.[Conclusion] 50% concentrations of reclaimed water can replace the control to irrigate cotton,it will not have a negative impact on lint quality.
