一、研究目的及意义随着城市化进程加快,城市绿地面积严重不足,城市热岛效应严重。藤本植物大多有很好的观赏价值,在城市垂直绿化中有着非常重要的作用。积极开展藤本植物的种质资源创新和优良品种的选育,丰富城市绿化植物材料,对于推动城市绿化事业的发展具有十分重要的意义。在老师的指导下,我开始对这爬上墙的绿色植物进行了研究。二、研究内容及方法1.研究内容(1)观察爬山虎的外部形态,并采
First, the purpose and significance of research With the accelerating process of urbanization, urban green space seriously inadequate, urban heat island effect is serious. Most of the vines have very good ornamental value and play a very important role in the vertical greening of the city. Vigorously carry out germplasm germplasm resources innovation and breeding of fine varieties, rich urban greening plant material for promoting the development of urban afforestation is of great significance. Under the guidance of the teacher, I started to study the green plants climbing the wall. Second, the research content and methods 1 research content (1) observe the external morphology of ivy, and mining
