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.
