Method for transplanting large-sized landscape tree in saline-alkali soil and structural layout for transplanted-tree pit

Abstract

The invention relates to a method for transplanting a large-sized landscape tree in saline-alkali soil. The method is characterized by mainly comprising the following steps: (1) preparing a seedling tree; (2) preparing a tree pit: (a) digging the tree pit; (b) laying a water seepage layer; (c) laying nutritional soil; (3) carrying out tree planting: (a) coiling a nutrient tube at the outer circumference of a soil ball; (b) adjusting the tree pit planting direction of the seedling tree; (c) arranging an observation well pipe at one side of the soil ball; (d) backfilling improved soil; (4) maintaining: (a) observing the water accumulation condition of the root of the tree; (b) conveying nutrient solution through the nutrient tube. The invention also relates to a structural layout of the tree pit for transplanting the large-sized landscape tree in the saline-alkali soil, wherein the water seepage layer is laid at the bottom of the tree pit, the nutritional soil is laid on the upper surface of the water seepage layer, and the observation well pipe is arranged. Compared with the prior art, the method and the structural layout have the advantages that the problems in large tree transplanting that the survival rate is low, the growth is slow, and the like are solved on the premise that an isolating layer is not arranged and a water seepage pipe or blind ditch is not laid to remove salt, the survival rate of the large tree transplanted in the offshore saline-alkali soil is increased remarkably, in addition, the implementation is simple and convenient, the cost is reduced, and the like.

Description

technical field [0001] The invention belongs to the technical field of large tree transplantation, in particular to a method for transplanting large landscape trees in saline-alkali land and the structural layout of transplanted tree holes. Background technique [0002] At present, with the ever-changing development of modern cities and the continuous improvement of landscape environment requirements, today's landscaping projects often have to reflect the effects of greening and beautifying in a short period of time, and the big trees are tall, graceful, and easy to transplant. Big trees can speed up the process of urban greening and quickly show the effect of plant landscaping. Therefore, tree transplantation is also more and more used in landscaping. [0003] All trees with a DBH of 10-20cm or more can be called "big trees" in garden engineering. Although the transplantation of big trees becomes a scene quickly, it is more difficult to survive than conventional garden see...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the technical problems in the known technology, the present invention provides a method to solve the problems of low survival rate and slow growth in the transplantation of large trees without setting an isolation layer, laying seepage pipes or blind ditch salt drainage, and proposes The method of transplanting large-scale landscape trees in saline-alkali land and the structural layout of transplanted tree holes can significantly improve the survival rate of transplanting large trees on coastal saline-alkali land
