随着科学技术的发展,桉树组培苗、人工杂交育种和扦插育苗技术的成功,使桉树速生丰产林栽培面积不断扩大,桉树木材的利用更加受到重视。筹建中的南宁造纸厂、北海高密度纤维板厂均以桉树为主要原料,可以预见桉树的种植面积必将迅猛发展。但是近年来,桉树青枯病在广西、广东、海南等省(区)广泛流行,给桉树生产造成了巨大的经济损失,极大地挫伤了桉树种植者的造林积极性,防治桉树青枯病已是亟待解决的重要课题。
With the development of science and technology, the success of eucalyptus tissue culture, artificial hybrid breeding and cutting seedling raising technology have made the cultivation area of fast-growing and high-yield forest of eucalyptus growing unceasingly, and the utilization of eucalyptus wood has been paid more attention. The construction of the Nanning paper mill, Beihai high-density fiberboard plants are mainly eucalyptus raw materials, we can foresee the planting area of eucalyptus is bound to develop rapidly. However, in recent years, the widespread epidemic of eucalyptus bacterial wilt in Guangxi, Guangdong and Hainan provinces has caused tremendous economic losses to eucalyptus production and greatly eroded the enthusiasm of eucalyptus growers in afforestation. The control of eucalyptus bacterial wilt has been An important issue to be solved urgently.
