今天库尔勒香梨网为大家带来的是:怎么防治库尔勒香梨环纹花叶病?

(1)栽培无病毒苗木

取37℃恒温下处理2~3周后长出来的库尔勒香梨苗新烧顶芽,进行组织培养,繁殖无毒单株。再嫁接到独离苗上,不显示出特有症状确认为无毒后,用作母本树,繁殖接触。用种子实生苗做钻木,进行繁殖、育苗。

(2)禁止在田间生产上的大树上高接或繁殖无病毒新品种

一般杂交育成的或从国外引进的新品种,多数是无毒的。禁止把无毒接穗在未经检毒的梨树上进行高接或保存,以防受原来带毒大树的病毒感染。

(3)加强库尔勒香梨苗检疫

防止带毒苗木的病毒蔓延扩散,应建立健全无病毒母本树的检验和管理制度,把好检疫关,杜绝病毒的侵入和扩散。
