在古田县5种园地作物土壤上采集耕层土壤样品7023个，调查园地作物状况，探讨土壤养分供应与土壤主要性质之间的关系。结果表明，供试园地土壤平均有机质含量为25.38 g/kg，pH 值为5.07，全氮含量为1.20 g/kg，碱解氮、有效磷、速效钾含量分别为143.5 mg/kg、29.95 mg/kg 和59.3 mg/kg，各养分含量均与土壤有机质含量和 pH 之间呈极显著正相关。供试园地土壤全氮含量中等，碱解氮、有效磷含量较高，78.51％的土壤速效钾处缺乏水平。提高有机质含量和改良土壤酸度是供试园地土壤改善养分供应状况的根本措施。%7 023 topsoil samples were collected in 5 kinds of garden crops soil in Gutian County,crop con-dition were investigated to explore the relationship between soil properties and soil nutrient supply.The results show that,the average content of soil organic matter,total nitrogen,alkali hydrolyzable nitrogen,available phos-phorus,available potassium and pH in garden soil were 25.38 g/kg,1.22 g/kg,143.5 mg/kg,29.95 mg/kg, 59.3 mg/kg and 5.07,respectively.There were moderate content of total nitrogen,higher content of alkali hydro-lyzable nitrogen and available phosphorus,78.51% soil lack of available potassium in garden soil.To improve the content of organic matter and soil acidity was the fundamental measure for the tested garden soil improving nutri-ent supply conditions.
