土壤理化性质与卫青萝卜品质相关性研究

Study on the correlation between soil physicochemical properties and the quality of Weiqing radish

为了揭示各项土壤理化因子对“卫青”萝卜品质的影响,分析了天津市武清和西青产区的土壤理化因子差异及其与萝卜品质的相关性。结果表明,西青和武清产区土壤质地分别为重壤土、轻壤土。西青产区土壤全磷、有机质以及镁、钙、砷、镉、钴、铬、铜、锰、钼、镍、铅、锌元素含量均显著高于武清产区,而土壤全钾、速效钾、速效氮、有效磷含量显著低于武清产区。相关性分析发现萝卜蛋白质、可溶性糖、可溶性固形物、维生素C、粗纤维和水分含量与多个土壤理化因子呈不同程度正相关,其中可溶性糖含量与土壤有效磷和速效钾含量呈显著正相关,可溶性固形物、蛋白质含量与土壤电导率呈显著正相关。因此,在萝卜生产过程中,可结合土壤的理化特性,针对性地进行田间管理和常规施肥,以改善和提升萝卜品质。

To reveal the effects of soil physicochemical factors on the quality of Weiqing radish,the differences in soil physicochemical factors and their correlation with radish quality were analyzed in Wuqing and Xiqing production areas of Tianjin.The results showed that the soil textures of the Xiqing and Wuqing production areas was heavy loam and light loam.The contents of total phosphorus,organic matter,and magnesium,calcium,arsenic,cadmium,cobalt,chromium,copper,manganese,molybdenum,nickel,lead and zinc were significantly higher in Xiqing than those in Wuqing,while the contents of total potassium,available potassium,available nitrogen,and available phosphorus were significantly lower than those in Wuqing.Correlation analysis revealed that radish protein,soluble sugar,soluble solids,vitamin C,crude fiber,and water contents were positively correlated with several soil physicochemical factors to varying degrees,of which the soluble sugar content was significantly positively correlated with soil available phosphorus and available potassium contents,and soluble solids and protein contents were significantly positively correlated with soil electrical conductivity.Therefore,in the process of radish production,the physicochemical characteristics of the soil cowld be combined with targeted field management and routine fertilization to improve and enhance the quality of radish.
