| 摘 要： | 四会地区是中国重要的沙糖桔产区,重点对威整和地豆两处沙糖桔园进行了生态地球化学调查。采集了沙糖桔园表层至底层土壤、出露的代表性基岩、沙糖桔叶和果实样品,实测了营养、有益和有害元素以及土壤营养元素有效态的含量。通过分析得出:(1)优质沙糖桔产区植物营养、有益元素含量适宜,重金属元素中Cd、Cr、Hg等的含量符合无公害水果产地环境要求;(2)在土壤—沙糖桔生态系统中,大多数有益、营养元素从深部到表层的变化规律具有相似性;(3)沙糖桔各器官(叶、果皮、果实)中,元素大多在叶中较为富集,有害元素在果实中富集较小,大多数营养元素在果皮中较果肉中富集;(4)成土母质以砂岩及花岗岩发育而成的赤红壤较适宜,尤以砂岩为母质的土壤更好。

| Abstract: | This study carried out an eco-geochemistry investigation on Shatang citrus plantation field in Weizheng and Didou of Sihui,Guangdong Province.Soils,leaves and fruits of citruses were sampled from Shatang citrus plantation field,and the contents of their nutritional,beneficial and harmful elements were measured.The measurements revealed the following results:(1)in the high-quality Shatang citrus producing area in Sihui,the content of beneficial and nutritional elements is suitable,and the content of harmful elements,such as Cd,Cr and Hg is in accord with the environmental demand of the unpolluted-fruit producing area;(2)in the ecological system of soil-Shatang citrus,the variation regularity of total and effective contents of beneficial and nutritional elements is similar to each other from the depth to the surface;(3)in different organs of Shatang citrus,i.e.leaves,pericarps and fleshes,elements are enriched mostly in leaves,and harmful elements are enriched a little in fleshes,and the content of beneficial and nutritional elements in leaves are higher than that in fleshes;(4)the crimson soil with the parent materials from granites or sandstones(especially sandstones),is relatively suitable for planting Shatang citrus. |
