植树是以苗木作为造林材料进行栽植的造林方法。苗木栽植后,在正常情况下,根系能较快恢复吸水机能,以适应造林地环境,顺利成活。在相同条件下,采取植苗造林的方式,造林后幼林郁闭早,生长快,成林迅速,且适宜植苗造林的树种和立地条件很广泛,因此,该造林方式在造林绿化中采用的最多。 苗木成活率的高低受多种因素影响。苗木的成活除受苗木生活力影响外,还取决于根系从土 Tree planting is based on seedlings planted as afforestation afforestation methods. After planting seedlings, under normal circumstances, the roots can quickly recover the water absorption function, in order to adapt to the afforestation land environment, smooth survival. Under the same conditions, the planting and afforestation methods are adopted. After afforestation, the young stands can be closed for the first time, grow fast, grow quickly, and the tree species and site conditions suitable for plantation and afforestation are very wide. Therefore, the afforestation method is the most used in afforestation. The survival rate of seedlings affected by many factors. In addition to seedling survival by the vitality of seedlings, but also depends on the roots from the soil
