Dredger fill sludge mud flat structure and rapid greening planting method thereof

Abstract

The invention discloses a dredger fill sludge mud flat structure and a rapid greening planting method thereof. The dredger fill sludge mud flat structure comprises a sludge mud flat, a plurality of planting grooves are dug in the sludge mud flat, greening trees are cultivated in the planting grooves through cultivation soil, the cultivation soil is arranged to be in a circular truncated cone shape, fixing sand is arranged on the outer side of the cultivation soil, and filtering sand is arranged at the bottom of the sludge mud flat. According to the structure, the sludge mud flat on a sludge coast is made into a slope shape, the stability performance of the greening trees can be improved through the circular-truncated-cone-shaped planting grooves, the root systems of the greening plants are reinforced through the fixing sand, the greening trees are fixed through greening tree fixing frames, the greening trees are prevented from being shaken by sea wind, rapid rooting of the greening trees is facilitated, and the survival rate of the greening trees is increased; loess is laid on the top of the sludge mud flat, lawns are planted on the loess, the effect of preventing water and soil loss is achieved, and the greening effect is achieved; and underground water can be collected to irrigate the greening lawns, and the problem of irrigation difficulty is solved.

Description

technical field [0001] The invention relates to the field of afforestation and planting of muddy tidal flats, in particular to a structure of muddy tidal flats with dredging fill and a rapid greening and planting method thereof. Background technique [0002] The silty coast is composed of silt or silt mixed with silt (mainly referring to silt with a particle size of 0.05-0.01 mm), and is mostly distributed along the coast of large river estuaries that input fine-grained silt. Because most of the silt flats are fertile, they are often developed as good places for tidal flat farming. The coast of the Bohai Bay is well-known both at home and abroad for its rich meat and delicious shellfish such as cockles and xishi tongue. At the same time, muddy beaches are also treasures for drying salt. China's famous Tanggu Salt Fields and Subei Salt Fields are all located in muddy coastal areas. Due to tidal currents, muddy coasts often develop tidal trenches of various sizes. It is ver...

Problems solved by technology

It is very difficult to carry out greening and planting on the muddy coast. Due to the influence of the sea breeze, the green trees are easy to fall and the roots are not easy to take root. Moreover, it is difficult to grow green plants on the muddy beaches, and the irrigation of green plants is also limited. Therefore, the cost of greening and planting on the muddy coast is high and the effect is poor. For this reason, a dredging muddy beach structure and its rapid greening and planting method are provided.
