通过对湖北巴东北部地区东氵囊口、沿渡河与溪丘湾三镇的名优柑桔、柚子与茶叶生态农业试验基地的实地考察和土壤样中 18项地球化学指标的特征分析 ,着重研究了该名特优果茶试验基地的土壤地球化学背景与柑桔、柚子、花生和茶叶等农作物长势之间的关系 ,认为该区柑桔与柚子基地的土壤环境总体良好 ,少数劣质柑桔、柚子地区土壤过高的 pH值以及相对缺乏的营养元素和矿质组分 ;而茶叶土壤已受到一定程度的As污染 ,但总体土壤环境适合种植茶叶。文章最后提出了控制劣质保持优质柑桔、柚子和茶叶生长的措施。
Through the field investigation of the eco-agricultural experimental bases of famous citrus, grapefruit and tea in three towns of Dongjiao, Yanduhe and Xiqiuwan in the northern part of Badong in Hubei province and the analysis of the characteristics of 18 geochemical indicators in the soil samples, The relationship between the geochemical background of citrus tequila fruit base and the growth of crops such as citrus, grapefruit, peanut and tea is that the soil environment of citrus and grapefruit base in this area is generally good. A few inferior citrus, grapefruit The pH value of the soil in the area is too high, and the relative lack of nutrients and mineral components; while the tea soil has been contaminated with As to some extent, but the overall soil environment is suitable for the cultivation of tea. The article concludes with a list of measures to control the poor quality of citrus, grapefruit and tea leaves.
