一、保持树体水分代谢平衡大树,特别是未经移植或断根处理的大树,在移植过程中,根系会受到较大的损伤,吸水能力大大降低。因此,保持树体水分代谢平衡是新植大树养护管理、提高移植成活率的关键。1.地上部分保湿包裹树干。用草绳、蒲包、苔藓等材料严密包裹树干和比较粗壮的分枝。经包裹处理后,一可避免强光直射和风沙吹袭,减少树干、树枝的水分蒸发;二可贮存一定量的水分,使枝干经常保持湿润;三可调节枝干温度。目前,有些地方采用塑料
First, to maintain tree water metabolism balance trees, especially without the transplantation or root treatment of large trees, the transplant process, the root will be greater damage, greatly reduced water absorption capacity. Therefore, to maintain the balance of tree water metabolism is the new planting tree conservation management, improve the survival rate of transplants the key. 1. The ground part moisturizes the trunk. With grass rope, baguette, moss and other materials tightly wrapped trunk and relatively thick branches. After parcel processing, one can avoid direct sunlight and wind and sand blown to reduce the trunk, branch of the water evaporation; two can store a certain amount of water, so that branches often keep moist; three adjustable branch temperature. At present, plastic is used in some places
