    摘要:

    为研究浙北地区不同土地利用方式下土壤理化性质的变化特征,以水田、水浇地和果园为研究对象,测定土壤pH、有机质、全氮、有效磷、速效钾和部分样品容重、阳离子交换量和水溶性盐含量。结果表明:①土壤pH为果园>水田>水浇地,且水浇地的土壤pH显著低于果园和水田;②土壤有机质为水田>果园>水浇地,且水田的土壤有机质显著高于果园和水浇地;③3种土地利用方式之间全氮含量没有显著性差异,土壤有效磷为水浇地>果园>水田,且水浇地和果园的有效磷含量均显著高于水田,土壤速效钾为果园>水浇地>水田,果园的速效钾含量显著高于水田;④土壤容重、阳离子交换量和水溶性盐含量在水浇地和果园之间没有显著差异。本研究结果可以为浙北地区土地资源合理利用、科学施用肥料和农业高质量发展提供参考。

    Abstract:

    In order to study the characteristics of soil nutrient changes under different land-use types in Northern Zhejiang Province, soil physiochemical properties of paddy fields, irrigable fields and orchards were measured, including pH, organic matter (OM), total nitrogen (TN), available phosphorus (AP), available potassium (AK), bulk density (BD), cation exchange capacity (CEC) and water-soluble salt. The results showed that: 1) pH was in an order of orchard>paddy field>irrigated field, pH of irrigated field was significantly lower than those of orchard and paddy field; 2) OM was in an order of paddy field>orchard>irrigated field, OM of paddy field was significantly higher than those of orchard and irrigated field; 3) There was no significant difference in TN among the different land-use types, AP was in an order of irrigated field>orchard>paddy field, AP of irrigated field and orchard were significantly higher than that of paddy field, AK was in an order of orchard>irrigated field>paddy field, AK of orchard was significantly higher than that of paddy field; 4) There was no significant difference in BD, CEC and water-soluble salt between irrigated land and orchard. These results can provide a reference for the rational use of land resources, scientific application of fertilizers and high-quality development of agriculture in Northern Zhejiang.
