摘要
近几年,滨州市城区部分行道树出现生长缓慢,树势衰弱现象。通过土壤检测和现场调查发现根系和地上部分生长空间不足、土壤盐碱化、肥水不足、整形修剪和虫害防治不到位等是引起行道树长势衰弱的主要原因。针对以上问题提出了加强部门间协调,合理规划、扩穴改土、补充肥水、加强修剪及病虫害防治等解决措施。
In recent years,some of the street trees have grown slowly and feebly in urban areas of Binzhou City.In order to understand the debility reasons of the street trees,an investigation is conducted.It is found that the main reasons of slow growing of the street trees are the lack of growing space of root system and above ground part,soil salinization and alkalization,the lack of fertilizer and water,the lack of pruning and pest control,and so on.In view of the above problems,some countermeasures are taken in the paper,such as coordination between departments,rational planning,tree point expanding and soil improvement,supplement of fertilizer and water,strengthening of pruning and pest control.
