摘要：

为了验证两种不同的柑桔黄龙病综合防治理论指导对柑桔木虱和黄龙病的防控效果，笔者于2006－2008年在桂林良丰农场开展大面积对比试验，3年的试验结果表明：以控制木虱为重点的柑桔黄龙病综合防治区都没有观察到柑桔木虱，8年生无病苗定植区3年累计发病率为1.71％、年平均发病率为0.57％，分别比对照区减少19.41％和6.47％；6年生常规嫁接苗定植区3年累计黄龙病株率只有1.35％，年均0.45％，分别比对照区减少8.31％和2.77％。传统的柑桔黄龙病综合防治区（对照区）每年都观察到木虱，8年生无病苗定植区3年累计黄龙病株率高达21.12％，年均7.04％；6年生常规嫁接苗定植区3年累计黄龙病株率也达到9.66％，年均3.22％。

Abstract:

In order to verify the prevention and control effects of two different kinds of citrus huanglongbing integrated control theories guidance on citrus psyllid and huanglongbing. large-scale comparative test was carried out in 2006-2008 in Liangfeng farms of Guilin. The results showed that citrus psylla was never been observed in citrus Huanglongbing integrated preventing areas which focus on controlling psylla. Three-year cumulative incidence rate is 1.71% and the annual average incidence rate is 0.57% in 8-year-old disease-free seedlings planting area, reduced by 19.41% and 6.47% to comparative areas respectively while three-year cumulative incidence rate is 1.35% and the annual average incidence rate is 0.45% in 6-year-old conventional grafting seedling planting area, respectively, reduced by 8.31% and 2.77% to the contrast area respectively. Citrus psyllid was observed in traditional huanglongbing integrated control areas (contrast area) every year. 3-year cumulative huanglongbing strain rate is as high as 21.12% and the average annual 7.04% in 8-year-old disease-free seedlings planting area. Three-year cumulative strain rate reached by 9.66%, with an annual 3.22% in 6-year-old conventional grafting seedling planting area .
