摘要:

为了解浙中低山丘陵区不同区域的土壤肥力现状,在永康市采集土壤样品780份,分析了整体及不同区域的土壤pH值、有机质、全氮、有效磷和速效钾含量等肥力指标。结果表明:永康市耕地土壤有明显的酸化倾向,整体以酸性和微酸性为主;有机质和全氮含量整体较为合理;有效磷含量两极分化现象较为明显,仅12.56%的位点的有效磷含量较为适宜;速效钾含量整体偏低,71.03%的位点速效钾含量低于120 mg·kg-1。总体来看,作为浙中低山丘陵区土壤的典型样本,永康市不同区域土壤的土壤肥力差异明显,土壤肥力指标含量不均衡,土壤酸化倾向较为严重。因此,需要在浙中低山丘陵区全面落实测土配方施肥等措施,均衡土壤肥力水平,提高耕地质量,防止土壤酸化的加剧。

Abstract:

In order to understand the current situation of soil fertility in different areas of the low mountain and hilly areas in central Zhejiang, 780 soil samples were collected in Yongkang City. The fertility indicators such as soil pH value, contents of organic matter, total nitrogen, available phosphorus and available potassium in the overall and different areas were analyzed. The results showed that the cultivated land soil in Yongkang City had a significant acidification tendency, mainly acidic and slightly acidic overall. The contents of organic matter and total nitrogen were generally reasonable. The polarization phenomenon of available phosphorus was relatively obvious, and the available phosphorus content at only 12.56% of the sites was relatively appropriate. The overall content of available potassium was relatively low, and the available potassium content at 71.03% of the sites was lower than 120 mg·kg-1. Overall, as a typical sample of soil in the low and hilly areas of central Zhejiang Province, the soil fertility in different regions of Yongkang City varied significantly, the content of soil fertility indicators was unbalanced, and the tendency of soil acidification was relatively serious. Therefore, it is necessary to fully implement measures such as soil testing and formula fertilization in the low mountain and hilly areas of central Zhejiang, so as to balance the soil fertility level, improve the quality of cultivated land, and prevent the aggravation of soil acidification.

Key words: central Zhejiang, soil fertility, soil acidification, quality of cultivated land
