Abstract

The invention discloses an ecological base stock for field planting engineering of a mangrove forest, a preparation method for the ecological base stock and application of the ecological base stock. The ecological base stock for field planting engineering of the mangrove forest is prepared from a porous material, peat, a functional microbe and decomposed manure of livestock and poultry, wherein aratio (in parts by mass) of the porous material to the decomposed manure of livestock and poultry to the peat is (1 to 5): (2 to 3): (5 to 10); and the addition level of the functional microbe accounts for 1.5%-3.5% the total mass of the ecological base stock. The functional microbe is bacillus amyloliquefaciens IAE. The porous material comprises ceramsite, biochar large granules and a macro-porosity lightweight substance; the peat comprises pearlite and coco coir; and the decomposed manure comprises fermented chicken manure and cattle manure. The ecological base stock is laid in holes of a tidal flat for transplanting young mangrove plants. According to the ecological base stock, pores of soil/deposit are increased, water exchange capacity of the deposit is improved, the oxygen content ofroot systems of the young mangrove plants is increased, and the survival rate and growth speed of the young mangrove plants are increased.

Description

technical field [0001] The invention belongs to the technical field of vegetation restoration ecology and engineering materials, and in particular relates to an ecological base material for mangrove planting engineering, a preparation method and application thereof. Background technique [0002] Mangrove is a tropical and subtropical coastal ecosystem with great primary productivity, and has the functions of resisting storm surge and storm wave, preventing coastal erosion, and promoting disaster prevention and mitigation of tidal flat deposition. The construction of mangroves is an important starting point to realize the ecological disaster reduction of the coastline. [0003] In areas where natural disasters such as storm surges and storm waves land on the shoreline, the shoreline often lacks mangrove barriers, causing seawalls to collapse, flooding villages and farmland, and causing huge social and economic losses. In recent decades, coastal development, factories, reclam...
