摘要
对六安市裕安区3523个土壤样品的pH值进行了测定。结果表明:裕安区土壤的pH最大值7.44,最小值3.66,平均值5.43,属于强酸性。其中,pH≤4.5的土壤样品数为35,占1%;4.5<pH≤5.5的土壤样品数为2090,占59%;5.5<pH≤6.5的土壤样品数为1343,占38%;6.5<pH≤7.5的土壤样品数为55,占2%。据此,给出了改良的合理化建议。
The soil pH value of 3 523 soil samples from Yu＇an District of Liu＇an City was determined. The results showed that the average soil pH value of Yu＇an District is 5.43, which belonged to strong acid; its max pH value is 7.44 and the minimum pH value is 3.66. 35 soil samples are pH ≤4.5, 2 090 soil samples are in the range of 4.5 〈pH ≤5.5, 1 343 soil samples are in the range of 5.5 〈pH ≤ 6.5 and 55 soil samples are in the range of 6.5 〈pH ≤〈 7.5. According to these results, a series of reasonable advices for improvement were proposed.
