Chinese tamarisk transplanting planting technology at dredger fill original soil area

Abstract

The invention aims at the greening problem of the sea mud dredger fill high saline and alkaline area, transforms the past greening mode with high input and poor benefit, takes the ecological engineering sciences and natural vegetation successional law as the guide, adopts the principle that suitable soil is adaptive to the suitable tree (plant) and suitable soil is adaptive to the suitable method, adopts the salt tolerance of the Chinese tamarisk and adopts the manual work partial improved dredger fill for reducing the salt content in the planting hole of the Chinese tamarisk and the soil at the periphery less than 3% in a short time, after satisfying the growing requirement of the salt tolerance plant as the Chinese tamarisk, the Chinese tamarisk seedling is transplanted nearby. The Chinese tamarisk is used for improving the coil and reducing the salt content in the soil, the Chinese tamarisk can attract the insect, birds and other animals for greatly changing the ecological environment. The Chinese tamarisk transplanting novel technology for the dredger fill region is low in cost and fast in effect and has continuity. The technology can offer strong technology guarantee for developing and building the coastal region and improving the environment.

Description

technical field [0001] The invention belongs to the field of landscaping greening construction, in particular to a method for greening the original soil of dredging land reclamation in coastal dredging land reclamation areas. Background technique [0002] The land area of ​​Tianjin Binhai New Area is 2270 square kilometers, among which the coastal saline soil with a salt content greater than 6g / kg accounts for 43.9% of the total land area. And according to incomplete statistics, the current area of ​​dredged landfill in the new area is more than 300 square kilometers. Land reclamation is an effective way to expand ports, industrial development space and urban construction land. In recent years, coastal areas have been rapidly expanded to shallow seas and tidal flats, and land reclamation is unstoppable. At present, Tianjin Port and Beitang Tourism and Leisure Resort , Lingang Economic Zone, Nangang Industrial Zone, etc. have been reclaimed for 200km 2 Around, planning to r...
