| 摘 要： | 为探求再生水灌溉对甘蔗产量及品质的影响,在大田试验条件下,试验设置再生水灌溉、清水灌溉以及无灌溉(天然降雨,CK)3种方式,每个处理设置三个重复。试验研究表明,由于再生水中富集的As、Hg等重金属元素对蔗种萌芽有抑制作用,再生水灌溉处理的萌芽率低于清水灌溉处理和无灌溉处理(CK),但再生水中富含N、P、K等元素,可以有效促进甘蔗的分蘖和蔗茎的生长,总的来说,再生水灌溉可提高甘蔗的单产,其单产分别比清水灌溉处理和无灌溉提高17.31%和80.35%;再生水富含N元素,在甘蔗成熟期灌溉会对甘蔗含糖分的累积有轻微的影响;再生水灌溉的重金属分布趋势是根部的重金属累积量最多,其次是蔗茎,最小是蔗叶,即根茎叶。再生水灌溉可促进甘蔗提高单产,但对甘蔗含糖分、重金属在蔗体的累积也有影响。

Effect of Fresh Water and Sewage Irrigation on Yield and Quality of Sugarcane |

| Abstract: | For ensuring safe reuse of reclaimed water irrigation (RWI),the effect of irrigation with reclaimed water on quality and yield of sugarcane was research.The experimental results showed that the yields of sugarcane which irrigated with reclaimed water increased by 17.31% and 80.35%,respectively,compared with those of freshwater irrigation treatment and non-irrigation treat-ment.Reclaimed water was rich in N element,and the accumulation of sugar in the mature period of sugarcane was increased slight-ly.The heavy metal in the root of sugarcane was higher than that in the stalk,which in the leave was the lowest. |
