园林绿化施工主要是园林植物的栽植过程。植物材料基本是移植而来的。移植成活率及植株长势是园林绿化施工质量的重要指标。植物成活率与移植期﹑植物根再生能力﹑树体储存物质多寡﹑是否断根﹑移植技术措施及植后管理密切相关。
Landscaping construction is mainly the planting process of garden plants. Plant materials are basically transplanted. The survival rate and plant growth rate are important indexes of landscaping construction quality. The survival rate of the plant is closely related to the period of transplantation, the ability of plant root regeneration, the amount of storage material in the tree, the root pruning, the technical measures of transplantation and the management after planting.

The survival rate and the growth of plants are important indicators of the quality of landscaping. The survival rate of plants is closely related to the transplant period, the regeneration ability of the plant root, the amount of storage material in the tree body, whether the root is broken, the technique of transplantation and the post-transplant management are closely related.

移植成活的内部条件主要是树势平衡,即外部条件确定的情况下(正常温﹑湿度),植株根部吸收供应水﹑肥能力和地上部分叶面光合﹑呼吸和蒸腾消耗平衡。移植枯死的最大原因,是根部不能充分吸收水分,茎叶蒸腾量大,水分收支失衡所致。在春季施工,由于植株未展叶,根系萌生﹑再生能力旺盛,树势不会出现严重失调,只需对未发芽的枝条进行适宜修剪,平衡树势即可。
The survival of transplanted trees is the main internal conditions of equilibrium, namely the external conditions to determine the conditions (normal temperature and humidity), the plant root absorption of water and fertilizer supply ability and aboveground foliar photosynthesis, respiration and transpiration consumption balance. The biggest reason of transplanting dead is that the root can not absorb the water adequately, the transpiration of stems and leaves is large, and the water budget is unbalanced. In the spring of construction, not because of plant leaf, root initiation, high regeneration, growth does not appear serious disorders, only of ungerminated branches suitable pruning, tree vigor can balance.
Transplant survival internal conditions is mainly tree potential balance, namely the external conditions determine (normal temperature, humidity), under the condition of water supply plant roots, fat part of leaf photosynthetic capacity and the ground, breathing and transpiration consumption balance. The biggest reason for the death of transplant is that the root cannot absorb the moisture adequately, the stem leaf is large and the water balance is unbalanced. Construction in the spring, because the plant is not flowing, root initiation, regeneration, tree potential won't appear serious imbalance, simply did not sprout branches for appropriate clip, balanced tree potential.

因此按植物生存生长规律出发,传统的做法是从3月中旬开始至5月初结束或者是10月中旬至11月下旬。此间是正常施工季节。此外的时间,生长旺盛的夏季;冬季的极端低温与根系休眠缺乏再生能力;都造成移植成活比较困难。这与形势发展及特殊要求的矛盾形成了非正常季节施工的难点。
Therefore, according to the plant survival and growth regularity of the traditional approach is from mid March to early May end or mid October to late November. This is the normal construction season. In addition, the vigorous summer, extreme winter temperature and dormancy of the roots lack the ability to regenerate, which makes graft survival difficult. This contradiction with the development of the situation and the special requirements formed the difficult construction during the abnormal season.
So the traditional way of doing this is to start from mid-march to the beginning of may or from mid-october to late November. This is the normal construction season. In addition, in the summer of high growth; The extreme low temperature in winter and the lack of regeneration in the root system; It is difficult to make a transplant. This contradicts the development of the situation and the contradictions of the special requirements.

为解决非正常季节绿化施工中遇到的难点,我们可以从种植材料的选择、种植土壤的处理、苗木的运输和假植、种植穴和土球直径、种植前的修剪及种植等方面严格把关，从而尽可能提高种植成活率。
In order to solve the difficulties of non normal season greening construction, we can from the planting material selection, planting soil treatment, seedling transplanting, transportation and planting hole and soil ball diameter, before planting pruning and planting strictly, so as to improve the survival rate of planting as much as possible.
To solve the abnormal season greening difficulties encountered in construction, we can choose from plant materials, planting soil processing, transportation and provisonal planting seedling, ball diameter, the hole and soil before planting clip and planting strictly controlled, so as to enhance the survival rate of planting as much as possible.
