广东廉江青平土壤质量及农产品生态效应评价

THE QINGPING SOIL QUALITY AND AGRICULTURAL PRODUCT ECOLOGICAL EFFICIENCY IN LIANJIANG,GUANGDONG

本文对广东廉江青平镇“红江橙”种植基地土壤质量及农产品生态效应评价。研究表明该区土壤环境质量较好,所有土壤均为无污染风险土壤。但土壤养分水平较低,多种营养、有益元素普遍缺乏。钾和有机质最为严重,是影响养分等级最主要的指标。区内“红江橙”样品大部分重金属含量水平较低,与相对应的根系土样进行重金属含量相关性分析发现,有害元素与根系土相关关系不明显,重金属从土壤进入农作物的危害性较小。

In this paper,we have a study on the soil quality and agricultural product ecological efficiency of Qingping Hongjiang orange planting base in Lianjiang,Guangdong,which shows that the soil environment quality of this area is good,all soil belonging to the soil without pollution risk,but the soil nutrition is low,generally lack of many nutritious,useful elements.K and organic material are very short of,seriously influence soil quality.The heavy metal content of most Hongjiang orange samples in this area is low,the heavy metal content correlative analysis of corresponding root system soil sample shows the correlation of harmful element and root system soil isn't clear.The risk of heavy metal entering agricultural product from soil isn't serious.
