| 摘 要： | 采用不同盐分含量的海冰水进行棉花灌溉试验,结果表明:①经过1年3次灌溉和降雨淋洗作用,海冰水盐分含量为1g/L、3g/L和5g/L的灌溉处理,土壤均表现为明显的脱盐效果,在0～20cm表层土壤脱盐率随海冰水盐分含量升高而降低,脱盐率最高为1g/L处理,达到57.22%,分别高于3g/L和5g/L处理3.28%和18.34%;而盐分含量为7g/L和9g/L的灌溉处理0～80cm土壤各层次表现为积盐,以60～80cm积盐最为严重。②各处理以1g/L和3g/L海冰水灌溉棉花果枝数、单颗棉桃重和产量最高,随灌溉水盐分含量增加产量呈递减的趋势,9g/L海冰水灌溉3次的处理与无灌溉相比出现显著减产,减产率为28.48%;7g/L和9g/L的2个处理,棉花整齐度指数和断裂比强度都有降低趋势,但各处理间棉纤维品质差异不显著。综合考虑海冰水长期灌溉效应及海冰脱盐技术,建议采用3g/L海冰水进行棉田灌溉,并要注意配合必要的灌溉和排水措施。 |

| Abstract: | Freshwater shortage is one of serious problems for agricultural productions over the coastal areas of the Bohai Bay. Sea ice water could be a new alternative to be utilized in agricultural irrigation in this region. In the present work, the authors carried out a field cotton irrigation experiment using sea ice water with different salt contents (1 g /L, 3g /L, 5g /L, 7g/L and 9g/L) in Zhongjie Farm located in Hebei province, with the objective to examine the effects of sea ice water on soil salt content, co... |
