| 中文摘要: |
| 新郑大枣种植区位于河南省中部黄淮平原区西侧,表层土壤以全新统灰黄色亚砂土为主,为冲积-风积堆积物。深部为更新统亚粘土层,为坡积-洪积物。为了查明大枣种植区土壤中的地球化学元素与新郑大枣中元素含量的关联特征,在开展农业地质调查时,在大枣种植区采集了表层土壤样、浅表层土壤样、土壤有效态样和植物样品,分别进行了多种元素分析。查明表层土壤中富K2O、Na2O、SiO2,浅表层与表层土壤地球化学特征基本一致。通过相关分析表明新郑大枣中富含的无机元素与表层土壤无关,与古土壤呈正相关。重金属元素在大枣种植区土壤中基本上处于低背景状态,反映出土地环境质量优良。 |
| 英文摘要: |
| Xinzheng jujube planting area is located in the west of Huanghuai Plain in central Henan Province. The surface soil is mainly composed of Holocene grayish yellow sandy loam, which is alluvial aeolian deposit. The deep part is the Pleistocene loam layer, which is the slope proluvial deposit. In order to find out the correlation between geochemical elements in soil and quality of jujube in Xinzheng. During the agricultural geological survey, surface soil samples, shallow surface soil samples, available soil samples and plant samples were collected in jujube planting area, and multiple elements were analyzed. It is found that the surface soil is rich in K2O, Na2O and SiO2, and the geochemical characteristics of shallow and surface soil are basically consistent. The correlation analysis showed that the inorganic elements in Xinzheng jujube had nothing to do with the surface soil, but positively correlated with the paleosol. Heavy metal elements in the soil of jujube planting area are basically in a low background state, reflecting the good quality of the land environment. |
