Transplanting method for big tree

Abstract

The invention provides a transplanting method for a big tree. The method comprises three main steps: preparation before transplantation; transplantation; and management after transplantation. The concrete steps of the method comprise root cutting and shrinking to a root ball, nutrient and water management before transplantation, pruning before transplantation, treatment of a transplanting hole and backfilling soil, tree lifting, transporting, field planting, supporting, nutrient and water management after transplantation, pruning after transplantation, soil loosening, weeding and pest and disease control. The transplanting method for the big tree provided by the invention enables the survival rate of the transplanted big tree to increase to more than 95%, which is significantly higher than the survival rate in the prior art.

Description

technical field [0001] The invention relates to the technical field of seedling transplantation, in particular to a method for transplanting large trees. Background technique [0002] In urban landscaping and tree protection work, it is often necessary to transplant large trees. The so-called big trees generally refer to arbor species with a diameter at breast height of more than 15 cm. However, large trees have long age, old stage development, weak cell regeneration ability, and well-developed main root. Therefore, it is easy to cause underdeveloped root system after transplantation, tree body dehydration, nutrient deficiency, poor drought and waterlogging resistance, etc., resulting in low survival rate of large tree transplantation. [0003] Chinese invention patent 201210160592.4 (transplanting method of garden seedlings), introduces a method of transplanting garden seedlings, and introduces the transplanting technology of large trees from the aspects of preparation bef...

Problems solved by technology

However, it uses a one-time ring-shaped root removal in the root removal and shrinkage, which destroys the root system of the big tree as a whole, affects the absorption of tree nutrients and the germination of new roots; in addition, when the rainwater is too much, the planting pit cannot filter Due to the effect of water, the root system of the big tree is damaged after transplanting. When the soil contains too much water, it is easy to cause the root system to rot, and eventually the big tree cannot survive after transplanting.

[0004] In addition, most of the existing technologies choose to infuse the tree body after transplanting the tree to supplement nutrients. Although this can make up for the nutrients that the tree cannot independently produce and absorb during the transplanting process to a certain extent, it is a bit of a "remedy" after all. means
