为了探索枣疯病树的治疗方法,1980—1985年对万余株病树进行手术治疗试验,平均治愈50%左右,轻病树的治愈率可达60—70%。通过对 MLO 在病树体内时空变化规律的初步研究认为,手术治疗有效的原因可能有:1.发芽前主干环锯,可阻断根部越冬的 MLO 向地上部运行;2.彻底锯除病枝、切断侧根、去除病芽等可能去除病原;3.手术后导致树体新陈代谢的改变,有可能促使MLO 的死亡。手术治疗的效果比较稳定,而且其方法简便宜行,适于在生产中推广。
In order to explore the jujube tree disease treatment, 1980-1985 more than a thousand strains of trees for surgical treatment trials, the average cure of about 50%, the cure rate of light tree can reach 60-70%. Based on the preliminary study on the temporal and spatial changes of MLO in the diseased tree, the reasons for the effective surgical treatment may include: 1. Pre-germination trunk trephination can block the overwintering MLO in the root to run to the shoot; 2. To thoroughly remove the diseased branch , Cut off the lateral roots, removal of diseased buds and other pathogens may be removed; 3. After surgery led to changes in the tree metabolism, may promote the death of MLO. The effect of surgical treatment is relatively stable, and its method is cheap, suitable for promotion in the production.
