随着城市建设的发展,在城市道路拓宽、老城区改造中,常常会遇到大树、古树,有的采取绕道的方法,有的则避让不开,只能让树“搬家”。怎样才能在保护树木的前提下搬走这“宠然大物”呢?笔者多次参与大树移栽,颇有一些经验和体会。一、土壤的选择与处理要选择通气透水性好,有保水保肥能力、土内水、肥、气、热状况又较协调的土壤。经多年实践,用泥沙拌黄土(3:1为佳)作为移栽后的定植用土比较好。它有三大好处:一是与树根有亲合力在栽培大树时,根部与土往往有无法压实的地方,经雨水的侵蚀,泥沙拌黄土能自动落下与树根贴实;二是通气性好。能增高地温,促进根系的萌发;二是排水性能好雨季能
With the development of urban construction, large roads and old trees are often encountered in urban redevelopment and urban transformation. Some adopt detour methods, while others avoid and can only make trees “move.” How to remove this “pet big thing” under the premise of protecting trees? I repeatedly involved in transplanting trees, quite a few experiences and experiences. First, the selection and treatment of soil to choose a good ventilation, water and fertilizer capabilities, soil water, fertilizer, gas and heat conditions and more coordinated soil. After years of practice, soil mixed with loess (3: 1 is better) as transplanting planting soil is better. It has three major advantages: First, affinity with the tree roots in the cultivation of trees, the roots and the soil often can not be compacted place, the erosion of rain, silt Loess can automatically fall down and roots affix; secondly Good ventilation. Can increase ground temperature, promote root germination; Second, the drainage performance of rainy season
