我们知道在夏季气温很高，阳光也十分强烈，不管是树木自身还是树下的土壤，水分散失及蒸发都十分严重，这是影响树木能否安全度夏的关键因素。
We know that in summer, the temperature is very high and the sunlight is also very strong. Whether it is the trees themselves or the soil under the trees, water loss and evaporation are very serious, which is a key factor affecting whether trees can safely survive the summer.
想要减少树木水分蒸发的方法有很多，在园林养护过程中常见的主要有喷施蒸腾抑制剂、往树冠及枝叶上进行喷雾，还有就是搭设遮阴网。
There are many ways to reduce water evaporation of trees. The common methods in garden maintenance are spraying transpiration inhibitors, spray on tree crowns, branches and leaves, and setting up shading nets.
搭设遮阴网是高温季节移栽树木最常用的一项降温、防蒸腾措施。通过遮挡部分阳光以及辐射从而来营造一个小的气候环境，使树木周围的温度、湿度、光照等能处于一个相对来说比较合适树木生长的状态。
Setting up shading nets is the most commonly used cooling and transpiration prevention measure for transplanting trees during the hot season. By blocking some sunlight and radiation, a small climate environment is created, allowing the temperature, humidity, and light around the trees to be in a relatively suitable state for tree growth.
但是在搭设遮阴网的过程中，由于工人操作失误、或者技术指导不够到位，常常出现明明搭设了遮阴网，反而却使树木枝叶干枯、死亡更快的现象。
However, during the process of setting up shade nets, due to worker errors or inadequate technical guidance, it is common for trees to wither and die faster despite the installation of shade nets.
