Large-sized Chinese ash transplanting method

Abstract

The invention discloses a large-sized Chinese ash transplanting method, and relates to the technical field of tree transplanting. The method comprises the following steps: (1) large-sized Chinese ash is selected; and transplanting is carried out during the Chinese ash dormant period in winter and spring; (2) pruning and root cutting treatments are carried out, wherein the root range is no smaller than twice the tree diameter; (3) water retention is carried out during long-distance transportation, wherein: a, all cuts after pruning and root cutting treatments are sterilized and disinfected; b, the cuts are sealed by smearing a smearing agent; and c, the entire Chinese ash trunk is sealed by spraying a liquid mulch film; (4) bond-rooting is carried out during a planting process; (5) watering is carried out, wherein first three times of watering after Chinese ash planting should be between the 15th and the 30th in the lunar calendar; and (6) aeration is carried out after watering, wherein pits with depth of 10-20cm are dug around the tree for aeration after 4-7 days of the first watering; hoeing and scarification are carried out after second watering; and deep-hoeing and scarification are carried out after third watering. The method is simple and easy. With the method, survival rate is high, investment is low, effect is good, and benefit is high.

Description

technical field [0001] The invention relates to the technical field of tree transplanting. Background technique [0002] With the improvement of landscape engineering requirements and the acceleration of urban ecological environment construction, transplanting large-scale seedlings plays an important role in improving the image and grade of green space landscape as soon as possible. There is no city, and the ash tree is salt-alkali, drought-resistant, and frost-resistant. It has an irreplaceable ecological role and special function in the greening construction of the eastern coast and northern big cities. However, it has been proved by production and market practice that large-scale ash tree seedlings are too old, the regeneration ability of root cells is weak, the ability of root system recovery and new root rooting is not strong, the transplanting technique and survival rate (the survival rate of annual cultivation is 50%), It has always been a hot and difficult issue tha...

Problems solved by technology

However, it has been proved by production and market practice that large-scale ash tree seedlings are too old, the regeneration ability of root cells is weak, the ability of root system recovery and new root rooting is not strong, the transplanting technique and survival rate (the survival rate of annual cultivation is 50%), It has always been a hot and difficult issue that plagues the nursery stock garden industry, and the application and research and development of core production technology related to it has become a practical issue that the industry pays special attention to.

The reasons why large-scale ash trees are difficult to survive after transplanting are: old trees, poor regeneration ability; many root injuries, difficult recovery; long-distance transportation and water loss, which seriously damages the root-cap balance after transplanting, and the respiratory area and transpiration area are unbalanced
