Problems solved by technology

[0005] The propagules of the current mangrove planting technology are seeds or young saplings. The way to cultivate mangrove plants is the same as that of conventional greening seedlings. The nursery germinates the seeds, and then transplants the mangrove seedlings to the beach. The root system causes damage, which seriously weakens the stress resistance of mangrove plants and reduces the growth rate of mangrove plants; moreover, compared with the nursery environment, the beach environment is very harsh, and the transplanted mangrove seedlings will lose a large number of seedling plants when they adapt to the beach environment
Manual seedling cultivation and transplanting are cumbersome, and the survival rate of seedlings is low during the transplanting process, which seriously hinders the work efficiency of large-scale restoration of mangroves
[0006] At this stage, especially when it comes to landscape engineering areas, in order to improve the survival rate of mangrove plants, methods such as embedding steel plates in front of the saplings and building dikes are used to protect the saplings from waves and tidal impacts. Such engineering measures are costly. Considering the red Due to tree plant growth restrictions and landscape needs, secondary construction will be carried out in the later stage, which will cause damage to the shoreline environment

Abstract

The invention discloses an ecological engineering product and a preparation method and application thereof. The ecological engineering product is a degradable ecological engineering product made of cement, stone, sand, plant fiber, humus, microorganism strain peplos body and a plant nutrient substance peplos body for filed planting mangrove forest on strong wave mobilization force coast. The functional microorganism bacillus amyloliquefaciens in the engineering product promotes the rapid rooting of mangrove forest seedlings, inhibits plant pathogens, and decomposes plant fibers within the ecological engineering product at the same time; the humus regulates pH of raw materials; peplos plant nutrient substances continue to provide nutrients such as nitrogen, phosphorus and potassium; and theplant fibers are beneficial to the degradation of the ecological engineering product after field planting of the mangrove plants is carried out. The engineering product creates a stable living environment for the seedling germination and early growth of the mangrove plants, and promotes the rooting and field planting of the mangrove plants. Experiments show that the use of the engineering producton the strong wave mobilization force coast can facilitate early field planting of the mangrove plants, and the survival rate of plant seedlings is increased by 10-15 times.

Description

technical field [0001] The invention belongs to the technical field of vegetation restoration ecology and engineering materials, and specifically relates to an ecological engineering product and its preparation method and application. Background technique [0002] Mangrove is a vegetation community that grows in the tropical and subtropical intertidal zone. It has good salt tolerance and plays a huge role in reducing waves and promoting siltation, purifying sewage, and resisting typhoons. At the same time, it provides coastal organisms with survival Habitat to maintain the ecological balance of the coastal zone. [0003] Since the 1970s and 1980s, due to the influence of various factors such as tidal flat reclamation and aquaculture activities caused by the population growth in coastal areas, the area of ​​mangroves in the world has decreased sharply. During 2009, 20% of the world's mangroves were lost. In the past ten years, people have realized the necessity of restoring...
