通过近几年走访各个施工单位和养护现场，发现部分树木缓苗期长或者栽植后没多久死亡，原来和我们绿化施工过程中的细节有关，现把这些误区分享给大家，仅作参考：
In recent years through the visits of all construction units and maintenance site, found that some trees or long slow seedling planting not long after death, and we turned out to be related in the process of green construction details, we put these ideas to share with everyone, only for reference:
1、雨天栽植
1, rainy planting
绿化施工人员为抢时，抓进度，头顶大雨栽植苗木，这种行为似乎可以减少浇水这一环节，实则这种行为不可取，这样栽植根部被糊状泥土埋压，通透性极差，不利于苗木的成活生长。
Green construction personnel grasp the progress to grab, heavy rain, head of planting seedlings, this behavior seems to reduce the watering of the link, but this behavior is not desirable, so planting root is burying the soil paste, poor permeability, is not conducive to the survival and growth of seedlings.
2、带袋栽植
2. Planting with bags
绿化施工人员为了省工常将苗木连同营养袋(或者遮阴网、草绳等）一同埋入土中，这种省工的行为虽然能保证苗木栽后短时间内的成活，但由于营养袋较难腐烂，限制了苗木根系四周生长，从而易形成“老小株”苗；同样草绳经长时间腐烂后对土壤的理化性状会造成一定的破坏。建议对袋苗必须先除去营养袋后再栽植为宜。
Green construction personnel to labor often together with nutrition bag seedlings (or shade net, rope etc.) together are buried in the soil, the behavior of labor can ensure the survival of seedlings planted after a short period of time, but because the nutrition bag is difficult to limit the rot, seedling root growth and easy to form around, from the "old line" seedlings the same rope; after a long time decay on physical and chemical properties of the soil will cause some damage. It is suggested that the bag seedlings should be removed first and then planted.
3、垃圾土上栽植
3. Planting on waste soil
绿化施工人员开穴栽苗时，对穴内的垃圾诸如塑料袋、石灰渣、砖块等不予清除，将苗木直接栽植，苗木在这种恶劣的小环境中成活率无疑极低。建议在开挖穴时遇到建筑垃圾或生活垃圾等杂物时，一定要清理彻底然后再栽植，确保建植绿地的质量。
Green construction workers open hole seedlings, the garbage in the hole, such as plastic bags, lime residues, bricks and other will not be cleared, the seedlings directly planted, seedlings in this kind of small environment, the survival rate is undoubtedly very low. It is suggested that the construction waste must be cleaned up and then planted in order to ensure the quality of the green land when the construction waste is encountered in the excavation.
4、栽植过深或过浅
4. Planting too deep or too shallow
绿化施工人员易忽视苗木土球的大小和苗木根系的深浅而将苗木放入穴中覆土而成，这样对小苗和浅根系苗木易造成栽植过深埋没了根颈部，苗木生长极度困难，甚至因根部积水过多而窒息；对大苗木和深根性苗木易造成栽植过浅，根部易受冻害和日灼伤，风吹易倒伏等。建议要视苗木的大小和苗木根系的深浅来确定栽植深度，以苗木根颈部露于表土层为宜。
Green construction personnel ignored nursery soil ball size and seedling root depth and the seedlings into the soil cave and so on, and the shallow root cause seedling seedling planting too deep buried root neck, seedling growth is extremely difficult, too much by the Ministry of water and even suffocation; on seedling and deep root seedlings caused by planting shallow roots susceptible to freezing and burns, wind susceptible etc.. It is suggested that the planting depth should be determined according to the size of the seedlings and the depth of the root system of the seedlings, so that the roots and necks of the seedlings should be exposed to the topsoil.
5、未能及时浇透水
5, failed to timely pouring water
绿地栽植过程中遇到降雨或乌云压境时，施工人员常忽视了栽后浇水的环节，这极易因雨水里不够导致苗木缺水而死亡。建议待雨停后立即补浇透浇足。
When rain or clouds arrives green planting process, construction personnel often ignore the link of watering after planting, it is very easy to die due to rain water not enough to cause the seedlings. It is suggested that immediately after rain stop pouring and pouring foot thoroughly.
