猕猴桃溃疡病即将进入高发期,怎样防治?四川农业大学龚国淑教授给出了答案

猕猴桃溃疡病号称猕猴桃癌症,传染性强,发病快,其防治是世界性的难题。四川是猕猴桃种植大省,栽培面积60万亩,占全国的38%。受去年冬天低温的影响,今年四川一些猕猴桃主产区溃疡病发病率较高。“得了这个病,目前主要采取两大措施——砍树枝,喷一些药雾,喷药剂不稳定,多了也容易产生抗体。”现正是猕猴桃田间管理的关键时期。面对当前新冠肺炎疫情,如何将病害防治技术及时传递到广大种植手中呢?

四川农业大学龚国淑教授团队带来了猕猴桃溃疡病防治技术,以图文的方式通过四川农村报微信公众号推送给大家。

伤流期尽量不动枝剪,做好伤流期后整个生长季节的抹芽、摘心、捏尖和疏枝工作,控制徒长枝、旺长枝,培育中庸枝,使枝蔓配置均匀。冬剪应在落叶后立即进行,落叶偏迟的区域或品种可适当提早冬剪时间,四川猕猴桃产区宜在12月底前完成修剪工作。严禁在雨天修剪,修剪后及时涂抹伤口保护剂促进伤口提早愈合。
