Problems solved by technology

However, once the embankment net is destroyed, its embankment effectiveness will no longer exist, and the embankment effect can only be maintained for about 1-2 years
This technology can only be used as an experiment and lacks the advantages of large-scale promotion

Embodiment Construction

[0023] 1. Implementation process

[0024] The project process includes: soil salinity determination, material selection, material preparation, material identification and acceptance and other preparatory work; determination of sowing time, seed soaking, seed dressing, sowing, covering soil, covering grass, laying nets, fixing nets, real-time inspection Acceptance and other engineering measures; and post-maintenance work and measures such as fertilization, embankment effect investigation, species growth and reproduction observation, soil salinity dynamics, etc.

[0025] The specific process is as follows:

[0026] Soil salinity measurement: 3 weeks before sowing, collect soil samples in the field, 0-5 cm in 1 cm layer, 5-30 cm in 5 cm layer; use MIA-3 ion analyzer to measure soil salinity and pH in time. At the same time, the national standard methods GB7857-87, GB7173-87 and GB7853-87 were used to determine the contents of soil organic matter, nitrogen and phosphorus, respect...

Abstract

A direct seeding technique of vegetation for protecting the slope of newly built sea dike features that the direct seeding technique system and standard for regrowing vegetation on the slope of newly built sea disk in order to protect it are created to make the target vegetation survival on high-salinization and infertile sea dike. Its advantages include low cost, easy operation, saving time, and high survival rate of vegetation.

Description

[0001] 1. Technical field: the present invention belongs to the technical fields of ecological environment protection engineering and water conservancy engineering 2. Background technology [0002] Among the existing technologies, the following three technologies are used at home and abroad for seawall slope protection. [0003] 1. Turf transplant slope protection technology [0004] In the early stage of my country's "Ninth Five-Year Plan", it was mainly transplanted from the nearest thatch turf (10 cm thick) to protect the slope of the seawall and prevent rain erosion and wave attack. The cost is about 6-10 yuan / square meter: with the expansion of the reclamation area, In the latter part of the Ninth Five-Year Plan period, there was a shortage of Imperata turf, so it was necessary to search, purchase and transport Imperata turf far away from the newly built seawall. The average transportation distance was 32.8 kilometers, and the cost of slope protection increased significant...
