摘  要：
采集临安市山核桃(Carya cathayensis)产区8个乡镇共321个土壤样品,分析其主要理化性质。结果表明,不同乡镇山核桃林地土壤理化性质受成土母岩和人为经营的影响,具有一定的差异性,其中太湖源镇林地土壤容重最小,仅为0.9 g/cm3,总孔隙度最大,为65.86%;昌化、河桥、龙岗3个乡镇土壤砂粒(2~0.02 mm)含量较高,大于30%,而粉粒(0.002~0.02)含量则较低,小于46.0%;土壤pH值以河桥镇为高,pH6.17,太湖源镇最低,pH4.81;土壤有机质含量以岛石镇和太湖源镇为高,分别达38.00、35.54 g/kg,而河桥镇最低,为23.95 g/kg;昌化、岛石、太湖源3个乡镇水解氮、速效钾含量较高,分别达200.00、100.00 mg/kg;土壤有效磷和有效硫含量以岛石镇为最高,分别为10.80,24.90 mg/kg;不同乡镇山核桃林地土壤微量元素平均含量排序为锰>铁>锌>硼>铜,土壤有效锰、铁、铜含量以岛石镇山核桃林地土壤较高,分别为62.46、26.88、1.30mg/kg,而有效锌、硼则以清凉峰镇为高,含量分别为2.26,1.77 mg/kg。

摘  要：
Detection and analysis were made on physiochemical properties of 321 soil samples from Carya cathayensis stands in 8 towns and villages of Lin’an,the most famous hickory production area,Zhejiang province.The results showed that soil bulk density was the smallest(0.9g/cm3) but with the biggest total porosity(65.86%) in Taihuyuan.Sand content occupied more than 30% in Changhua,Heqiao and Longgang,but with the lowest silt content of 46.0%.The highest pH value was detected in Heqiao(6.17),and the lowest in Taihuyuan(4.81).Content of soil organic matter in Daoshi and Taihuyuan topped 38.00 and 35.54 g/kg.The content of hydrolytic nitrogen,available potassium in the soil was higher as 200.00 and 100.00 mg/kg in Changhua,Daoshi and Taihuyuan.Availability phosphorus and sulfur were 10.80 mg/kg and 24.90mg/kg in Daoshi.The mean content of trace elements in the soil of different town was as follows: Mn > Fe > Zn > B > Cu.The content of Mn,Fe and Cu was higher in Daoshi than that in other towns,respectively 62.46,26.88,1.30 mg/kg,the content of Zn and B was higher in Qingliangfeng,respectively 2.26,1.77 mg/kg.
