摘要
对福建莆田城厢代表性龙眼园土壤的农化性状进行了调查分析,结果表明:土壤酸度偏低,48.84%的果园土壤pH<5.0,有机质和代换性钙含量属中上水平,全氮和有效钼含量属中下水平,但碱解氮、有效锌、有效铁,特别是有效硼和有效铜普遍较缺乏,而有效磷、有效钾、代换性镁和有效锰则较丰富。据此提出了培肥果园土壤、合理施肥和矫治缺素等措施。
The agrochemical characters of typical longan orchards soil in Chengxiang county were investigated.The results showed that the values of soil pH were lower(pH〈5.0) for 48.84% of longan gardens in Chengxiang.For the longan orchards soil in Chengxiang,the contents of organic matter and exchangeable Ca were higher,and the contents of available P,available K,exchangeable Mg and available Mn were richer,while the contents of total N and available Mo were lower than that of normal level,whilst available N,available Zn and available Fe,especially available B and Cu were too low.Based on the data,measures of soil fertilization,reasonable fertilizing and remending practice of deficiency symptom were put forward.
