摘　　要："小老树"是造成我国柑橘单产偏低的一大关键因素,主要由品种、土壤、人为等因素造成。本文以四川东北地区集中连片的柑橘基地为例,通过实地走访调查,结合对橘园土壤营养状况和根系致病菌检测,分析造成该区域柑橘"小老树"的原因,并提出针对性的改造促产技术,以期促进四川及周边相似区域柑橘产业高质量发展。The small aged tree is a key factor causing the low yield of citrus in our country,mainly caused by variety,soil,human factor,etc.This paper took the concentrated and contiguous citrus bases in northeastern Sichuan as an example,through field visits and investigations,combined with the detection of soil nutrient status and root pathogenic bacteria in citrus orchard,analyzed the causes of the small aged trees of citrus in this area,and proposed production promotion measures,in order to promote the high-quality development of the citrus industry in Sichuan and similar areas.
