摘要
柑桔黄龙病是柑桔生产上的毁灭性病害,在田间主要通过柑桔木虱(Diaphorina citri Kuwayama)传播,目前尚无有效防治柑桔黄龙病的药剂。防虫网室种植柑桔是目前国内多个黄龙病高发区用以防控柑桔木虱及黄龙病的新型种植方式。2020年1月至2021年2月在广东惠州(黄龙病流行区)的一个沙糖桔结果园中,设置防虫网覆盖区和露天区,对网室区与露天区的树势、黄龙病流行状况、柑桔木虱发生情况、其他害虫发生情况及温湿度进行跟踪调查,并分析其差异。结果显示,与露天比较,防虫网室种植有利于增强健康植株的树势,对产量无不利影响;网室对温湿度的影响主要表现在湿度上,5月和7月网室内相对湿度分别升高1.96和1.81百分点,10月和11月网室内相对湿度分别降低6.73和7.20百分点;网室种植能减少柑桔害虫发生种类,减少柑桔木虱发生数量,减轻黄龙病病情,但会引起全年性粉虱数量增加和秋季(10-11月)柑桔全爪螨暴发。
Citrus Huanglongbing(HLB)is a devastating disease in citrus production,mainly spread by Asian citrus psyllid.There is no effective control chemical at present.In order to control the HLB through controlling the spread of Asian citrus psyllid(Diaphorina citri Kuwayama),the cultivation of citrus under insect-proof screen is a sustainable way of planting citrus.Shatangju citrus orchards in the endemic area of HLB in Huizhou,Guangdong Province were covered with insect-proof screens from January 2020 to February 2021,with uncovered orchards as control.The tree vigor,occurrence of citrus D.citri,HLB and other pests,temperature and humidity of the covered orchards and control were investigated and the differences were analyzed.The results showed that compared with control,insect-proof screen cultivation was beneficial to the improvement of tree vigor without adverse effect on yield.The insect-proof screens mainly influenced the humidity.The relative humidity in the insect-proof screen house was increased by 1.96 and 1.81 percentage points in May and July,respectively,and decreased by 6.73 and 7.20 percentage points in October and November,respectively.The insect-proof screen cultivation can reduce the varieties of citrus pests,the number of Asian citrus psyllids and the condition of Huanglongbing disease,but it could increase the number of whitefly throughout the year and cause the outbreak of citrus red mite(Panonychus citri McGregor)in autumn(October to November).
