新材料、新技术 在大树移植中的应用

大树移植是城市绿化建设中的一种重要技术手段，可以加快绿化步伐，迅速达到绿化、美化的园林效果。此外，大树移植也是在城市改建扩建工程中，保护已成林的古树和各种树木的有效手段。可见，大树移植是同林绿化施工中的一项重要工程。     

树干注射药物防治光肩星天牛

树干注射药物防治光肩星天牛诸晓玲光肩星天牛在通辽市城区已有十多年发生史了，目前对园林树木的危害较为严重。据查，全市３２条街路中已有１８条街路的树木受害，受害树木达２．５万株，占城区街路树木的５６％。为了控制天牛的蔓延，近几年我们先后采取了堵虫孔、插毒...     

对通辽市城区绿化的认识

城市园林化是衡量城市现代化文明程度重要指标。通辽市在20世纪80年代间曾被评为全国绿化先进城市，以规整有序的城市布局、葱郁多彩的园林绿化而闻名；20世纪90年代通辽市的城市建设又有了一个新的发展，成片的居住区被重新改建，众多的高楼大厦如雨后春笋般涌现。新建扩建了一批公园、广场和街道绿地，城市面貌焕然一新。     

通辽市城市植物多样性保护规划

在全面调查通辽市范围内栽植植物的基础上,提出了近几年通辽地区在保护原有植物的同时,通过引种驯化增加植物种类、丰富品种,提高栽培的物种多样性,扩大多样化种群的规模和均匀分布,最终使通辽市的植物物种数量接近东部地区先进水平,最终实现通辽城市与自然的发展。     

蝴蝶兰软腐病中一种新致病菌的分离与鉴定

 Soft rot disease often affects Phalaenopsis amabilis during the growing season. However, the pathogen of the disease is remaining poorly studied. In this study, bacterial strain R1 was isolated from soft rot tissues in Wuhan. The pathogenic, morphological, physiological, biochemical tests and 16S rDNA sequence analysis were carried out. The homology of 16S rDNA sequence between strain R1 and Pseudomonas grimontii was 99.72%, and its physiological and biochemical properties were also similar to those of Pseudomonas grimontiis. All these evidences indicated that strain R1 could be identified as a novel strain of Pseudomonas grimontii. The pathogenicity of the novel isolate was proved according to the Koch's postulates. This is the first report that Pseudomonas grimontii can cause soft rot disease of Phalaenopsis amabilis.
