| 摘 要： | 通过对辽宁省朝阳县羊山镇1990~1998年间营造的各类品种杨树发生溃疡病情况的调查,结果表明:栽植时一次性浇足水分(150 kg.穴-1)发病率仅为0.48%。说明浇水不足是引发生杨树溃疡病的重要因素;起苗时苗木根系损伤严重的,发病率较高;不同品种类型的苗木杨树溃疡病发生率有明显差异;欧美杂交杨和新疆白杨派抗病能力强,青杨派树种抗杨树溃疡能力差。

| Abstract: | Investigation on the situation of Botryosphaeria ribis infected on species of poplar which was constructed in Yangshan town of Chaoyang county in Liaoning province from 1990 to 1998,results showed that irrigation field with enough water(150 kg·den~(-1)) at the first time while planting,the incidence of this disease was 0.48%.Irrigating field without enough water could cause disease of Botryosphaeria ribis.Radication of seedlings were damaged seriously while lifting,thus the incidence of this disease was higher.The incidence of disease of Botryosphaeria ribis had significant differences infected on different species of poplar.The disease-resistance of Populus × euramericana cl.and Populus tomentosa(Xinjiang) was strong and that of Sect.Tacamahaca was bad. |
