乌鲁木齐市再生水灌溉对棉花品质的影响

摘要

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