园林绿化树木不仅是园林的主要植物,也是园林景观构成的主体,同时更是园林工作重点的目标性植物。因为园林绿化树木本身种类众多,其表现出来的生物学特性也是多种多样,它们在丰富园林景观的同时,也不可避免地提高了园林各项工作的难度与复杂程度。北方冬季干燥寒冷的天气对园林绿化树木造成不同程度的冻害伤害,不仅仅影响了园林绿化树木的美观,还会对园林绿化树木的生长甚至是生命带来影响。所以,我们需要在科学分析园林绿化树木受到低温冻害的缘由基础上,保护园林景观植物的完整性,更大地发挥园林景观和园林绿化树木的功能,帮助园林事业发展提供物质和管理基础。园林绿化树木低温冻害的有效防治应当依据绿化树木的养护以及管理实际,探讨园林绿化树木冻害的表现和类型,对低温冻害的部分进行科学处理,采取园林绿化树木管护的有效措施,从而推进园林工作沿着科学化、系统化的方向不断发展。 Landscaping trees are not only the main plant of the garden, but also the main part of the garden landscape. At the same time, it is also the target plant of the garden work. Because of the large variety of landscaping trees themselves, their biological characteristics are also diverse, while they are rich in landscape, but also inevitably increase the difficulty and complexity of the various tasks in the garden. Cold and dry weather in the north caused varying degrees of frost damage on landscaping trees, which not only affected the beauty of landscaping trees, but also affected the growth and even life of landscaping trees. Therefore, on the basis of scientifically analyzing the reason why the trees in the garden are subjected to low temperature frost damage, we need to protect the integrity of the landscape plants, give more play to the functions of the landscape and the landscaping trees, and provide the material and management basis for the development of the garden. The effective prevention and control of low temperature frost damage of landscaping trees should be based on the conservation and management of greening trees to explore the performance and type of frostbite trees, to deal with the part of low temperature frost damage, take effective measures of management and maintenance of landscaping trees, Work along the scientific, systematic direction of continuous development.
