摘要
为探明万荣县苹果园土壤基本养分及重金属污染现状,以万荣县规模面积超过30亩的14个代表性果园为研究对象,测定了0~40 cm土壤有机质、全氮、碱解氮、有效磷、速效钾、pH值、全盐量、铜、锌、镍、铅、铬含量。结果表明:万荣县苹果园土壤中有机质与碱解氮含量处于匮乏状态,土壤中有效磷与速效钾含量处于富余状态,土壤pH值偏高,全盐量处于正常水平,未发生铜、锌、镍、铅、铬等土壤重金属污染。为此,提出建议:万荣县苹果园应注重合理施用有机肥和氮肥。
In order to explore the status of soil basic nutrients and heavy metal pollution in apple orchards in Wanrong county,14 representative orchards with an area of more than 30 mu in Wanrong County were taken as the research object.The contents of soil organic matter,total nitrogen,alkali-hydrolyzable nitrogen,available phosphorus,available potassium,pH,total salt,copper,zinc,nickel,lead and chromium in 0~40 cm soil were determined.The results are as followings:the contents of organic matters and alkali-hydrolyzable nitrogen in the soil of apple orchard in Wanrong county were deficient;the contents of available phosphorus and available potassium in the soil were surplus;the soil pH was high;the total salt content was normal,and there was no soil heavy metal pollution such as copper,zinc,nickel,lead and chromium.Attention should be paid to rational application of organic fertilizer and nitrogen fertilizer in apple orchard of Wanrong County.
