不同类型烟草有机肥料成分的差异分析

摘要

We collected 10 types of tobacco organic fertilizer samples commonly used in tobacco -planting districts in middle Henan province, and studied and analyzed the differences in the compositions (total nitrogen, total phosphorus, total potassium, or-ganic matter, pH, moisture, humic acid, organic acid, lead, cadmium, chromium, arsenic and mineral nutrition elements ) of dif-ferent types of organic fertilizer .The results indicated that: for total nitrogen , total phosphorus , total potassium , organic matter , pH, moisture content , humic acid content these basic indicators , the labelled value and determination value of vast majority of fertil-izer types had obvious differences;while for the medium and trace mineral nutrition element indicators , there was a certain differ-ence between the above two .%收集了豫中烟区常用的10种烟草有机肥料样品，研究和分析了不同类型有机肥料中全氮、全磷、全钾、有机质、pH、水分含量、腐殖酸含量、有机酸、铅镉铬砷重金属和矿质营养元素等成分的差异。结果表明，对于全氮、全磷、全钾、有机质、pH、水分含量、腐殖酸含量这些基础指标来说，绝大多数肥料种类的标示值与测定值都存在明显差异，而中微量矿质营养元素等指标则存在一定的差异。
