Salt-alkali-resistant planting structure and planting method of big trees in tidal flat reclamation landscaping

Abstract

The invention relates to the field of landscaping, and particularly relates to a saline-alkali-resisting planting structure and planting method for landscaping trees in a tidal flat reclamation area.The invention mainly solves the technical problems that treatment and planting methods in saline-alkali soil are relatively complicated, large-specification seedlings such as cinnamomum camphora, celtis julianae and the like in the tidal flat reclamation area are low in survival rate, poor in growth vigor, and poor in landscape effect, the irrigation treatment area is small, the irrigation efficiency is low, and the like in the prior art. The method comprises preparation of a big tree soil ball; the big tree soil ball is buried in a first planting soil layer; the edge of the big tree soil ballis provided with a plurality of polyvinyl chloride (PVC) hollow pipes; the lower ends of the PVC hollow pipes are close to the bottom of the big tree soil ball; a second planting soil layer, an organic fertilizer layer, a third planting soil layer and a gravel layer are sequentially arranged under the first planting soil layer; each PVC hollow pipe comprises a main pipe and a lengthened pipe; theouter surface of the end part of each main pipe is in threaded connection with the inner surface of the end part of one corresponding lengthened pipe; each PVC hollow pipe is provided with thorough holes; and the edge of each through hole is provided with guide grooves.

Description

technical field [0001] The invention relates to landscaping, in particular to a salinity-alkali-resistant planting structure and planting method for large trees in landscaping landscaping in tidal flats. Background technique [0002] Saline-alkali land is a type of salt accumulation, which refers to a type of land where the salinity in the soil is high and affects the normal growth of plants. At present, the use of saline-alkali land is mainly in agriculture or forestry, for example, by improving saline-alkali land and then planting some saline-alkali-tolerant crops; or by planting some saline-alkali-resistant trees to establish shelter forests in saline-alkali land. A Chinese patent discloses a coastal saline-alkali land soil improvement technology (public number: CN108076718A). The first step is to wash the salt with fresh water, dig trenches and open ditches reasonably according to the terrain, and wash the salt with the accumulated fresh water to the saline-alkali land t...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a saline-alkali-resistant planting structure and planting method for landscaping landscaping in tidal flat reclamation land, which mainly solves the problems in the prior art that the treatment and planting methods of saline-alkali land are relatively complicated, and large-scale camphor trees and coral park trees are relatively complicated. Technical problems such as low survival rate of seedlings in tidal flat reclamation land, poor growth, poor landscape effect, small area of ​​irrigation treatment, low irrigation efficiency, etc.
