摘要: 文章主要回顾阐述2002—2017 年台州对柑橘黄龙病亚洲种和亚洲柑橘木虱防控研究结果。指出黄龙病在果园空间分布入侵初期呈均匀分布,后呈聚集分布,亚洲柑橘木虱在果园内也呈聚集分布状态;认为黄龙病对柑橘产量与品质影响是随着病级的上升增加。得出黄龙病疫情自然入侵扩散流行呈周期性变化规律,建立积年发病率(PI)与入侵年数(N)模型I=84.6740/[1+EXP(3.540-0.5838X)](n=14,r=0.9946**);检测发现黄龙病树体内和亚洲柑橘木虱带菌量在11 月和12 月最高,亚洲柑橘木虱带菌率同样以12 月最高。提出防治亚洲柑橘木虱除抓好春夏秋三梢期外,冬季和初春清园也是一个重要环节。台州探索实践的“九坚持”和“三防五关”防控模式对黄龙病防控和柑橘产业的可持续发展起到了积极作用,可在相似柑橘生态区推广应用。

Abstract: This paper mainly reviewed some researches on prevention and control of Candidatus Liberibacter asiaticus and Diaphorina citri in Taizhou from 2002 to 2017. It was found that the population of citrus HLB was distributed evenly in citrus orchards at the early stage of invasion, but subsequently developed in the pattern of aggregation. Accordingly, the population of Diaphorina citri belonged to the pattern of aggregation distribution. The effect on production and quality of citrus increased with the severe degree of citrus HLB. In conclusion, the pattern of invasion and epidemic diffusion of citrus HLB had a periodic change. A model between the cumulative incidence of HLB (PI) and its invasion year (N) was constructed as follows: PI=84.6740/[1+EXP (3.540-0.5838X)](n=14, r=0.9946**). In addition, tests showed that the pathogen population of Diaphorina citri in infected trees reached a peak in November and December. Meanwhile, the pathogen-carrying rate reached the highest in December as well. As a result, with the exception of three shoot stages (spring, summer and autumn), cleaning orchard in winter and early spring would also be an important part for controlling the citrus psyllid vectors. The“nine principles”and“three critical prevention periods and five tests”prevention and control technologies, which were explored and practiced by Taizhou, could play a positive role in the sustainable development of HLB control and citrus industry. These technologies can be popularized and applied to the similar citrus ecological zones.
