摘 要:通过对建瓯南雅早钟六号枇杷园土壤常量、微量元素含量的测定,结果表明:南雅枇杷园土壤中有机质、全N、全P、全K的含量分别是1.5%、0.091%、0.150%、1.34%。按全国土壤养分含量分级标准,有机质、全N和全K属于4级,都没有缺乏,但全K在缺乏的边缘;全P属于3级,中等;B、Ca、Mg重量百分率平均分别是0.75mg/kg、1.99mg/kg、0.29mg/kg。根据土壤微量元素和交换性元素含量分级标准,B属于3级,中等;Ca高于丰缺临界值(0.90mg/kg),表明Ca含量较高;Mg低于丰缺临界值(0.50mg/kg),表明枇杷园土壤中较缺Mg。结合本实验数据提出了一些施肥措施:加强有机肥料的施用;合理施用氮肥;适量增施磷肥;增施钾肥;合理施用硼肥;注意施用镁肥。This article through to the loquat garden of nanya of Jian′ou soil constant,the trace element con-tent determination,finally indicated that,The content of organic matter,total nitrogen,total phosphorus,total potassium of loquat garden of Changtai respectively is 1.5%,0.091%,0.150%,1.34%. According to the na-tional soil nutrient content graduation standard,the organic matter、total nitrogen and total potassium all be-long to four levels,all has not lacked,but total potassium in deficient edge;The total phosphorus belongs to three levels,medium;The weight percentage average of boron,calcium,magnesium respectively is 0.75mg/kg, 1.99mg/kg,0.29mg/kg. According to the soil trace element and the exchangeable element content graduation standard,boron belongs to three levels,medium;But calcium is higher than abundantly lacks the marginal value(0.90mg/kg),indicating that calcium content is too higher;magnesium is lower than abundantly lacks themarginal value(0.50mg/kg),indicating why in the loquat garden soil comparatively to lack magnesium. Unified this empirical datum to propose some applied fertilizer the measure: Strengthening the organic fertil-izer the employment;Reasonabling employment nitrogenous fertilizer;Right amount increases executing the phosphate fertilizer;Increaseing the potassium fertilizer to execute;Reasonable to employment boron fertilizer;Attention to employment magnesium fertilizer.
