摘要
对猕猴桃根腐病发生规律田间调查及防治试验研究结果表明:老龄园发病重于幼树园;栽植较深、土壤粘重、排水不良、透气性差的果园发病严重;改行间垄为行上垄有明显的预防效果,化学防治以根部晾晒后用地菌净800倍液灌根效果最好,防效达67.7%,甲霜灵锰锌防效次之,为64.2%.
It was showed by field investigation and control experiment that the root rot disease of Actinidia chinensis was more severe in orchards with old trees than those with young trees. It was found out that the disease occurred more seriously in orchards when the trees were over deeply planted, on heavy clay soils with poor drainage and poor gas permeability. It was proved that the disease could be effectively controlled by planting the tree rows on ridges instead of among the ridges. The disease could be also well controlled by pouring the roots with 800 x 'Dijunjing' chemical after the roots were aired, the controlling effect reached 67.7% in the experiment, and the control effect by 'Jiashuangling' chemical reached 64.2%.
