Inoculation effects of three ectomycorrhizal fungi (Xerocomus pulverulentus ,Armillaria luteovirens &Amanita vaginata )on Pinus koraiensis seedlings were studied by adopting pot-culture method.Result shows that X .Pulverulentus can form the mycorrhizal symbionts with Pinus koraiensis seedlings,which could improve the seedling height,ground diameter and dry biomass of Pinus koraiensis ;the colonization percentage reached by 61.5%;three mycorrhizal contribution rate is 50.39%,40% & 69.94%,respectively.X .pulverulentus can signifi-cantly improve the activity of phosphatase of soil in the rhizosphere soil,and promote the transformation of total phosphorus into available phosphorus activity,so as to improve the content of available phosphorus in the rhizo-sphere soil.The above result shows that the fungus of X .Pulverulentus have certain potential application of mycor-rhizal seedling of Pinus koraiensis .

<正>植病流行学把植病系统看成是整个农业生态系统的一个组成部分,注重在分析研究植病系统中病原物群体,寄主群体以及各种环境因素之间错综复杂的相互关系的基础上,综合解决问题。流行学的研究重视生态环境对流行的作用与影响。我们所研究的群体病害都是在一定的生态环境中发生的,反过来也影响到生态环境的改变。病理学家考虑

<正>我国随着华北、西北、内蒙古等地区樟子松的人工引种和造林面积的逐年的扩大,樟子松病害的种类、面积也逐年增加,枯梢病便是其一。松枯梢病自70年代后期在东北地区的樟子松中发现后迅速蔓延危害。目前,该病在辽宁、黑龙江樟子松人工林栽培地区大面积发生和流行,轻者影响树木的高生长,茎生长变慢,重者全株死亡,造成严重的危害,造成巨大的经济损失。本论文重点就该病害的发生、症状、病原菌、寄主、侵染循环、流行因素、防治措施等方面进行初步探讨。

森林并非是树木的简单集合,而是有一定结构,各成分之间相互作用、彼此制约,并与外界环境发生密切联系的极其复杂的集合体。森林病虫害的大面积发生,常使得林木及林副产品减产、甚至绝收,更有甚者森林病虫害会让大片林木死亡,造成大量森林资源的浪费。因此,森林病虫害的防治工作越来越受到林业工作者的高度重视。

An actomycete strain HD006 was isolated from the soil samples collected from Anda of Heilongjiang province.Its antagonistic activity against to pathogen of poplar leaf blight and the morphological appearance,cultural characteristics,physiological properties and biochemical characteristics of HD006 were analyzed.Homology analysis showed that its 16S rDNA sequence has the identity of 95.98% with Kitasatosporia phosalacinea.Strain HD006 was identified as K.phosalacinea var.Heilongjiang.

我们在对森林虫害进行治理时,从保护和改善生态环境出发,以实现可持续控制为目标,遵循预防为主、标本兼治的原则,严把检疫关,在加强监测的基础上,以营林措施为主,药剂防治为辅,协调运用人工、物理等措施,进行综合防治。只有这样,才能更好地治理好森林病虫害,促进我国林业的发展。

从樟子松枯梢病病害的症状、病原菌、病菌生物学特性、寄主范围、侵染规律、流行规律和防治技术等7个方面综述了近年来樟子松枯梢病的研究进展.

樟子松梢病的病原菌为松壳色二孢菌(Diplodia pinea),具腐生性,是一种典型的潜伏侵染的寄主主导病毒[1,2].因此,对该病的防治应以生态系统的自控能力和樟子松枯梢病流行规律为依据,采取以营林防治为主,生物防治、化学防治与之相结合的综合防治技术.

1999年,在黑龙江省尚志市一面坡林场进行了樟子松枯梢病综合防治试验.2003年根据防治试验林标准地的调查结果,经计算得知:防治所带来的经济效益非常显著,同时也说明樟子松枯梢病综合防治技术可以从根本上控制病害的发生与危害.

通过对樟子松叶、枝、芽、果等部位进行组织切片和真菌分离培养,鉴定出真茵24种,其中子囊茵3种、担子茵1种、半知茵20种.这些真菌种群在樟子松树体上可分为芽栖真菌、叶栖真茵、枝栖和果栖真菌4大类,其种类组成和数量与樟子松树龄、叶龄、枝龄、树冠层次等有密切关系.芽栖真菌种类和数量随树龄的增加而增多,叶栖真菌(特别是兼性寄生真茵)的种类和数量随叶龄的增加而增多,枝栖真菌种类和数量随枝龄的增加而增多.樟子松树栖真菌种群组成也随环境条件而发生变化,在发病的樟子松林分内樟子松枯梢病菌数量激增占主导地位,环境条件的恶化是促成变动的主要原因.在健康的樟子松林分内也广泛地分离到樟子松枯梢病菌,表明该病害是潜伏性的侵染病害.
