柑桔黄龙病综合防治研究

INTEGRATED CONTROL PROGRAM OF CITRUS HUANGLONGBIN DISEASE

实施以采用无病种苗和田间防疫为中心的柑桔黄龙病综合防治技术,在新区两项措施并举,现树龄已9～14年生,仍然健康高产,每hm^2产量达32600kg,田间保持既无黄龙病株,亦无柑桔木虱。对病区仅施行“田间防疫”,也能压低田间病株率和控制田间传染,维持果园效益。

The integrated control techniques including the planting of huanglongbin disease (Citri huanglongbin)free seedlings and the epidemic prevention in the field was implemented new non-infected zone of citrus orchard. The citrus trees have been healthy and high yielding although the trees are 9-14 years of age. The yield was up to 32600 kg/hm2. There are neither plants of huanglongbin disease nor citrus psylla (Diaphorina citri Kuw. ) vectors found in the field. It also reduced the rate of diseased plants and controlled the spread of the disease in the field when only was the epidemic prevention implemented in the orchard of infected zone. The profit of the orchard was therefore kept.
