Key Techniques for Transplantation with Full Crown of Big Trees in Summer

Transplantation with full crown of big trees in summer is often used in the landscaping construction at present. Key techniques were reviewed and discussed in this paper. We considered that the binding with wire netting in transplantation of big trees could replace with wooden cases. Antitranspirants technique should be studied and promoted in depth. It could take the place of the full-sunshine and spray technique when it gets matured. The technique of aerating the soil around roots should be used better when water collects easily in the place. Diseases and pests should be paid attention to around the infusion hole when we use the technique of nutrient fluid dripping. Some methods including root cutting, nailing boards in the tree trunk, fastening the tree around roots, watering regularly were suggested for transplantation with full crown of big trees in summer.
