摘　　要：通过调查城固县的6个柑橘主产区域,发现柑橘树体黄化现象越来越普遍,总体黄化率达到了38%,其中缺素引起的黄化约占20.9%、低洼地因积水和冻害导致黄化约占6.7%、病虫害危害引起的黄化约占比7.7%、其他管理原因等引起的黄化约占2.7%。柑橘黄化造成树体生长不良,产量下降,品质降低,严重影响了果农的经济效益。结合城固柑橘生产实际,建议采取合理建园、测土配方、及时防治病虫害、科学管理等对策进行综合管理以增强柑橘树体树势,减轻黄化发生情况,促进产业健康发展。The investigation was conducted in six main citrus producing areas in Chenggu county,the results showed that yellowing of citrus trees is becoming more and more common,and the overall yellowing rate has reached 38%,of which 20.9%of the yellowing was caused by lack of elements,6.7%of the yellowing was caused by surface ponding and freezing in low-lying land,7.7%of the yellowing caused by diseases and insect pests,and about 2.7%of the yellowing was caused by managements.Citrus yellowing caused poor tree growth,decreased yield and quality,which seriously affected the economic benefits of fruit growers.Combined with the actual citrus production in Chenggu,it is suggested taking countermeasures such as reasonable garden construction,soil testing and formula fertilizer,timely prevention and control of diseases and pests,scientific management,thus enhancing the tree potential of citrus trees,reducing the occurrence of yellowing and promoting the healthy development of this industry.
