梨园土壤有机质、氟以及金属元素的测定

On the Determination of Soil Organic Matter,Fluoride and Metal Elements

对果园土壤用蛇行布点法采样,测定了有机质、pH、水溶性氟、速效性氟、铜、铁、锌、锰、镁、铅、汞、砷含量.结果表明:该梨园土壤p H为6.75属于微酸性土壤;有机质含量为35.27 g·kg^(-1)、水溶性氟含量为6.64 mg·kg^(-1)、速效性氟含量为216.33 mg·kg^(-1)、铜含量为8.62 mg·kg^(-1)、铁含量为587.88 mg·kg^(-1)、锌含量为49.96mg·kg^(-1)、铁含量为587.88 mg·kg^(-1)、锰含量为57.57 mg·kg^(-1)、镁含量为8295.82 mg·kg^(-1)、铅含量为12.55 mg·kg^(-1)、汞含量为0.0745 mg·kg^(-1)、砷含量为2.1698 mg·kg^(-1).通过对梨园土壤的部分指标进行检测分析,为其高质栽培、污染控制、土壤改良提供一定的理论依据.

In this paper, orchard soil sampled by a meandering distribution method was determined. The re- suits showed ： the soil pH is 6.50 pear belong slightly acidic soil, Test results showed that the organic matter con- tent of 35.27 g · kg-1 the water - soluble fluorine content of 6.64 mg· kg-1 quick result fluorine content of 216.33 mg · kg-1 the copper content of 8.62 mg kg-1 iron content 587.88 mg · kg-1 a zinc content , 49.96 mg · kg-1 the total amount of iron content 587.88 mg · kg-1 the manganese content is 57.57 mg · kg- 1 the lead content of 12.55 mg · kg-1 the magnesium content to 8295.82 mg· kg-1 the mercury content was 0.0745 mg · kg-1, the arsenic content of 2. 1698 mg· kg-1. By some indicators pear soil analyzed provide a ref- erence for the cultivation of high - quality and oollution control.
