目前在城市园林绿化及旅游区、风景区、公园、公路两旁等绿化美化中普遍采用大规格的苗木进行栽植。大苗具有成形快、效果立竿见影、抵抗自然灾害能力强等特点。但由于青海省湟中县地处西北,受气候等原因的影响,绿化用针叶及常绿树种经常需要从外地引进。由于苗圃地环境与绿化地环境差异较大,容易造成移植苗木大量死亡,造成大量资金及劳力的浪费。为了提高移植苗木的成活率,可采用以下一些措施。
Currently in the city landscaping and tourist areas, scenic areas, parks, roads and other greening and landscaping are widely used in large-size seedlings planted. Large seedlings with forming fast, immediate effect, ability to resist natural disasters and so on. However, due to the fact that Langzhong County, Qinghai Province is located in the northwest, affected by climate and other reasons, green needles and evergreen species often need to be imported from the outside. Due to the large differences between nursery environment and greening environment, it is easy to cause a large number of deaths of transplanted seedlings, resulting in a lot of money and labor waste. In order to improve the survival rate of transplanted seedlings, the following measures can be used.
