Method for transplanting big trees, old tree and famous wood species having tree ground diameter greater than 20 cm in sandy lands in cold regions

Abstract

The invention belongs to the technical field of garden plant transplanting and cultivation, and particularly relates to a method for transplanting trees in sandy lands in cold regions. The method includes the following steps: a, irrigation; b, support establishment; c, vertical digging; d, straw rope winding; e, water spraying; f, tree inclined digging from groove bottoms; g, carrying; h, transplanting; and I, crown pruning of transplanted trees. The transplanting method can improve the survival rate of the transplanted trees, the test survival rate can reach above 95%, and the core problem that it is very difficult to transplant big trees in sandy lands can be solved.

Description

technical field [0001] The invention belongs to the technical field of transplanting and cultivation of garden plants, and in particular relates to a tree transplanting method in cold regions and sandy soil conditions. Background technique [0002] On the one hand, the modernization process of Chinese cities pushes the boundaries of urban land construction to a wider depth; on the other hand, the internal structure of cities often undergoes major adjustments and changes. Urban construction and landscaping are developing rapidly, especially landscaping. The requirements for landscaping are getting higher and higher. , Transplanting large trees and growing forests overnight are the requirements of landscaping and the direction of development. These have led to many large trees (with a diameter of more than 20cm) in the nursery and in the wild, as well as various ancient and famous trees. The fate of Xinjiang is no exception. Xinjiang has a large area, high latitude, cold, dro...

Problems solved by technology

Now there are a lot of demands for various transplanting of big trees and old trees in urban and road construction, and tree transplanting happens almost every day. As far as Xinjiang is concerned, according to statistics, large trees (with a diameter of more than 20cm) ) and the transplanting survival rate of ancient trees is not very high, usually not higher than 50%. The main reason is that the method of transplanting trees is simple, and usually digging and pruning are carried out according to conventional methods. Since it is sandy land, the root system cannot carry Soil balls, in the process of excavation and transportation, due to the large sand content, the sand will fall off from the root system in large quantities, and normal soil balls cannot be formed, and a large number of normal hairy roots are lost and dead, resulting in bare and semi-bare root transplanting. Such transplanting The plan did not follow the needs of the trees, that is, the transplanted trees, which caused a large amount of damage to the root system and serious damage during the transplanting process; Effective supply, resulting in the death of transplanted trees; because they are big trees and ancient and famous trees, the value of each plant is 10,000 to hundreds of thousands of yuan, resulting in a large amount of economic losses
