| 摘%20%20%20要：为了解万州区玫瑰香橙果园的土壤养分含量分布状况，共采集果园土样97份，分析土壤pH、有机质、氮、磷、钾和中微量元素含量，结果表明：92.79%的土壤pH适宜柑橘生长，土壤有机质平均含量为12.76g/kg，67.01%的土壤有机质含量不足，32.99%的土壤有机质含量适宜生长；土壤碱解氮含量缺乏（<100%20mg/kg）、有效磷含量缺乏（<15%20mg/kg）和速效钾含量缺乏（<100%20mg/kg）的样品比例分别为58.77%、66.67%和38.14%，土壤中有效铁、有效铜、有效锌、交换性钙和交换性镁的平均含量分别为88.98%20mg/kg、1.31%20mg/kg、1.79%20mg/kg、3.28%20g/kg%20和0.32%20g/kg。土壤有效铁、有效铜、交换性钙、交换性镁含量过高比例分别达93.81%、92.78%、93.81%和84.45%，存在过量现象，而有24.74%的样品有效锌缺乏。因此，在玫瑰香橙的生产中，需有机无机配施，针对性补充N、P、K，增施有机肥，提高土壤有机质，改良土壤，实现高产优质。 |
