摘要
分析测定福建三明小湖赤枝栲林部分矿质元素及土壤理化因子 ,结果表明 :该地区土壤 pH值为 4 2 4 ,全N平均含量为 0 0 84 2 % ,全P(P2 O5% )为 0 0 15 5 % ,有机质为 3 7874 %。该地土壤的全N、全P和有机质均不高。该地区土壤Mg元素含量为 6 2 6 0 4 4mg kg-1,Ca为 15 6 5 88mg kg-1,Mn为 80 4 4 4 3mg kg-1,Fe为 2 6 179 6mg kg-1,Co为 3 3335mg kg-1,Ni为12 94 6 7mg kg-1,Cu为 15 2 95 3mg kg-1,Zn为 2 6 9116mg kg-1,Mo为 0 4 6 4 1mg kg-1,Cd为 0 0 4 70mg kg-1,Pb为 9 786 5mg kg-1。土壤矿质元素中 ,Ca、Fe含量偏高 。
The results show that the ph value of the soil in this area is 4.24,total N average content is 0.0842%,total P(P 2O 5%)average content is 0.0155%,the organic matter average content is 3.7874%.The total N,total P and organic matter contents of the soil in this area all aren't high. The Mg element content of the soil in the area is 626.044mg/kg,the Ca,Mn,Fe,Co,Ni,Cu,Zn,Mo,Cd and Pb contents are 1565.88mg/kg,80.4443mg/kg,26179.6mg/kg, 3.3335mg/kg,12.9467mg/kg,15.2953mg/kg,26.9116mg/kg,0.4641mg/kg,0.0470mg/kg and 9.7865mg/kg respectively. The Ca,Fe contents are relatively high in soil mineral element contents,Mn content is relatively low.
