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.
