【摘要】：丁香作为市花对哈尔滨具有重要的景观价值和人文意义。从植物对不同环境的抗性角度出发,比较不同种类的丁香属植物,对园林树种中丁香的选择有重要价值。本文选取8种丁香属植物,小叶丁香、紫叶重瓣丁香、北京丁香、暴马丁香、白丁香、红丁香、蓝丁香和紫丁香,对不同树种叶片和土壤中的氮磷钾含量进行测定,对叶片中氯的吸附和硫的吸附以及土壤中微量元素的吸收能力进行比较研究。对土壤氮磷钾含量的测定以及叶片土壤中各项元素含量的测定均为符合国家标准的测定方法,并对数据进行相关性、差异性分析,进行隶属函数分析得到丁香属植物的抗性强弱。分析主要研究结果如下：对大气氯的吸收能力大小顺序为红丁香紫丁香暴马丁香小叶丁香白丁香蓝丁香紫叶重瓣丁香北京丁香；对大气硫的吸收能力大小顺序为紫丁香暴马丁香小叶丁香红丁香白丁香紫叶重瓣丁香蓝丁香北京丁香；对土壤有效铜的吸收能力大小顺序为紫丁香红丁香白丁香小叶丁香蓝丁香暴马丁香紫叶重瓣丁香北京丁香；对土壤有效锌的吸收能力大小顺序为暴马丁香白丁香小叶丁香紫丁香紫叶重瓣丁香红丁香北京丁香蓝丁香；对土壤有效铁的吸收能力大小顺序为紫丁香暴马丁香蓝丁香红丁香小叶丁香白丁香紫叶重瓣丁香北京丁香；对土壤有效锰的吸收能力大小顺序为红丁香紫丁香蓝丁香紫叶重瓣丁香小叶丁香暴马丁香白丁香北京丁香。综合分析8种丁香属植物的污染抗性,可得出8种丁香属植物抗污染性的强弱顺序为紫丁香暴马丁香红丁香蓝丁香小叶丁香白丁香紫叶重瓣丁香北京丁香。其中紫丁香的抗污染性最强,在所测定的六个抗性指标中均表现出较强的抗性,暴马丁香和红丁香次之；蓝丁香在土壤微量元素有效铁和有效锰当中吸收较好,但在大气的氯和硫吸收中能力较弱；小叶丁香在大气的氯和硫吸收中能力较强,但在土壤微量元素的有效铁和有效锰的吸收中较弱,与蓝丁香形成互补；白丁香仅在土壤微量元素有效锌吸收中表现较强,在其他几项指标中均表现较弱；紫叶重瓣丁香与北京丁香的各项指标均显示吸收力较弱。通过本试验发现,城市行道树及工厂厂区内宜选择紫丁香、暴马丁香、红丁香,为美观方面考虑也可以选择将小叶丁香与蓝丁香间隔种植,有利于其景观效应。
[Abstract]:Clove, as a city flower, has important landscape value and humanistic significance to Harbin. From the point of view of plant resistance to different environments, different species of clove plants are compared. In this paper, eight species of clove, clove, purple leaf double clove, Beijing clove, lilac, white clove, red clove, blue clove and lilac were selected. The contents of nitrogen, phosphorus and potassium in leaves and soils of different tree species were determined. The adsorption of chlorine and sulfur in leaves and the absorption capacity of trace elements in soil were compared. The determination of nitrogen, phosphorus and potassium in soil and the determination of elements in leaf soil were all in accordance with the national standard. And carries on the correlation, the difference analysis to the data, The main results are as follows: the order of the absorption ability of atmospheric chlorine is: the order of absorption ability is the double clove, clove, clove, lilac, purple leaf, double clove, lilac, lilac, lilac, lilac, lilac, lilac, lilac, lilac, lilac, lilac, lilac, lilac and lilac; The order of absorbability of atmospheric sulfur was lilac, lilac, lilac, lilac, white, lilac, purple leaf, double clove, blue, clove, Beijing clove; The order of absorbability of available copper in soil was lilac red clove white clove clove blue clove purple leaf double clove Beijing clove. The order of absorbability of available zinc in soil was as follows: (1) the order of absorbability of the soil available zinc was as follows: (1) the order of the absorption ability of the soil available zinc was: (1) the double valved clove red clove Beijing clove blue clove; The order of absorbability of soil available iron was lilac, lilac, lilac, red, clove, lilac, lilac, purple leaf, double clove, Beijing clove; The order of absorbability of available manganese to soil was double clove, blue, lilac and purple leaf. The pollution resistance of 8 species of clove was analyzed. It can be concluded that the order of resistance to pollution of 8 species of clove is: lilac, lilac, lilac, blue, clove, lilac, purple leaf, double clove, Beijing clove, among them, lilac is the most resistant to pollution, All of the six resistance indexes showed strong resistance, followed by clove and lilac, blue clove absorbed better in soil trace elements available iron and manganese, but weak in the absorption of chlorine and sulfur in the atmosphere. Clove has a strong capacity in the absorption of chlorine and sulfur in the atmosphere, but it is weak in the absorption of available iron and manganese in the soil, which is complementary to the blue clove, but only in the absorption of available zinc in the soil. The indexes of purple leaf double clove and Beijing clove showed weak absorbability. It was found that lilac, lilac, lilac, lilac, lilac were suitable for choice in city street trees and factory areas, the results of this experiment showed that: lilac, lilac, lilac, lilac, lilac, lilac, lilac, lilac, etc. For the sake of beauty, we can also choose to plant clove and clove separately, which is beneficial to the landscape effect.
