通过对莆田华亭、常太、西天尾三地果园土壤营养状况的实验测定和分析评价,初步掌握了三大名果龙眼、枇杷、荔枝生长的土壤环境质量现状与存在问题。结果表明:莆田果园土壤普遍偏酸,有机质不足;普遍严重缺氮(N)、磷(P)、钾(K),且氮、磷、钾比例失调;硼(B)、镁(Mg)、铜(Cu)、锌(Zn)元素缺乏;龙眼园和荔枝园钙(Ca)含量不足。根据实验分析结果进一步提出改良建议,为莆田果园绿色果品生产和可持续发展提出了理论依据,为果农、有关决策管理部门及科研机构提供了莆田果园土壤肥力的参考资料。Through measurement and evaluation of nutrient situation of soil in Huating、Changtai、Xitianwei,the condition and problem of the soil of longan,loquat and lichee could be investigated. The results indicated that the soil was too acid comparing to the normal condition,lack of organic matter,and generally even serious lack of the element of nitrogen,phosphorus,potassium. Meanwhile nitrogen,phosphorus,potassium were disproportional. The element of B、Mg、Cu、Zn are deficient. The element of Ca in longan and lichee orchards was not sufficient. Finally,considering the green fruit production and sustainable development,the further suggestions were given.
