| 摘 要： | 环渤海滨海地区淡水资源缺乏,季节性旱、涝与盐碱、地下潜水矿质化共生,是该地区农业生产极不稳定的主要原因。本文选择东营地区台田-浅池与黄骅重盐碱地实验台田-浅池为研究对象,采用野外实验与调查问卷相结合的方式,对比分析了两地台田-浅池模式脱盐效率和生产效益。结果表明气候季节性变化导致盐荒地表层盐量变化大,严重影响作物生长发育。台田减轻或遏制了季节性雨热条件变化下的剧烈反盐,耕层全年脱盐效率达58.8%,其中东营沙性土质台田耕层年平均脱盐效率为79.7%,种植棉花产量4500kg/hm2,与传统利用模式相比增加50%;黄骅台田耕层年平均脱盐效率为37.9%,种植棉花产量3000kg/hm2。台田浅池模式能起到降盐、稳盐及抗洪调蓄水源的作用,利于环渤海盐碱地粮食产量稳定和土地高效生产。本文研究结果可为环渤海重盐碱地土壤改造、粮食增产、土地综合利用提供重要参考。 |

| Abstract: | There are 30 million hectares of saline-alkali soil land in China, accounting for 7% of the total state-owned arable land. Fresh water resources are extremely scarce around the Bohai Sea coastal areas. In addition, droughts, waterlogging, salinity and groundwater mineralization frequently happen over the areas. As a result, agricultural productions for this region are extremely instable in general. In the present work, the land use pattern of the 'raised field-shallow pond' model for agricultural lands in D... |
