莆田市常太枇杷园土壤肥力与果树营养状况测定

Soil Fertility of Loquat Orchards and Nutrient Situation of Fruit Trees in Changtai Town,Putian City

莆田市常太镇枇杷园土壤肥力和叶片营养状况分析结果表明:枇杷园土壤偏酸,全N、Mg供给不足,B供给严重不足。有效P含量不高,K、Ca、Cu、Fe、Mn、Zn土壤供给充足,并有偏高趋势。枇杷叶片N、P、K、B、Mg质量分数未达到适宜指标,Cu、Mn、Zn、Fe含量偏高,与施用含重金属农药有关。据此提出了合理施药、培肥的农艺措施,为生态果园的建立提供理论依据。

The results showed that the contents of N, Mg, P were insufficient, and K, Ca, Cu, Fe, Mn, Zn contents were sufficient. B content was obviously insufficient of the loquat orchard soils in Changtai town of Putian city. The contents of N, P, K, Mg, B were insufficient of the loquat leaves, the contents of Cu, Mn, Zn, Fe were sufficient and with a high tendency. Based on these data, measures of reasonable soil fertilization and pesticide application were put forward.
