摘　　要：杨树溃疡病菌为弱寄生菌，具潜伏侵染特性．因此，适地适树、培养壮苗健苗和保证造林后及时返苗成活是杨树溃疡病可持续控制的关键，其主要措施有：选用抗病树种，划定主要造林杨树种的抗病适生区和杨树主要栽植区溃疡病发生的危险等级（ 重发区、常发区、偶发区、安全区） ，采用主要包括在造林中尽量减少水分损失，施用防病促生剂、诱导剂，根据造林地生态条件及经营强度分别采用带干、去梢、修侧枝及截干几种不同的造林方法等各种措施提高杨树的抗病性．造林后加强抚育管理及病虫监测．The pathogen is a weak parasite. It was characterized by latent infection. Violating the principle of matching species with the site, introducing the species of poplar blindly, planting the pure forest of large scale and extensive management provide favorable condition for development and epidemic of the disease. Therefore matching species with the site, culturing health and strong seedlings, ensuing the survival of the seedling is a key of the sustainable management of the poplar disease. The main measures are as follows: select resistant species of poplar, delimit the area of growth\|suitalbe and anti\|desease for the poplar in the main silviculture area: take various measure, including reducing the water loss as much as possible in the plantation, using the prophylaxis & growth promoting agent and inducer;according to the ecological condition of the plantation site and management strength, take different ways, such as buring root with stem, cutting shoot, stem or twig to raise the resistance of the poplar. In addition, strength management and investigation and forecast of the disease are very important after the planting.
