Problems solved by technology

However, due to the strong alkalinity of Portland cement as a cementitious material, the pH of the liquid phase in the voids in the concrete is generally as high as 12 or more, which is extremely unfavorable to the early planting and later growth of plants.
In addition, some traditional cultivation methods often make it difficult for plant roots to penetrate into the deep gaps in the concrete, which reduces the ability of the plants growing in it to resist the erosion of rivers
Therefore, the screening of suitable species and the optimization of cultivation methods will be an important way to realize the successful construction of ecological concrete vegetation. However, the current technology mostly focuses on the production process of ecological concrete, and there is relatively little research and application on the selection of suitable plants and the corresponding cultivation techniques. few

Embodiment Construction

[0019] The organic matrix of vinegar grains used in the present invention is the Hengxin brand powdered organic matrix of vinegar grains jointly developed by using waste residues from vinegar production, and is a slow-release matrix fertilizer. The matrix is ​​processed through a series of processes such as fermentation, turning, drying, molding, etc., after rationally adjusting the acidity of the acidic vinegar waste residue, adding carefully screened compound bacteria, and its organic matter content is as high as 35%. The total amount is greater than 4%, and the pH value is normally between 5.8-6.5. If it is used as an ecological concrete cultivation substrate, the pH value can be adjusted to about 5.5. In terms of form, the matrix has two kinds of powder and granular to meet different production needs.

[0020] The implementation site is on the ecological slope protection of Binjiang Avenue in a city in the lower reaches of the Yangtze River. The perennial wet season of th...

Abstract

The invention discloses a related culture technology and a method for constructing phalaris arundinacea population in ecological concrete spheres on a river bank protection slope, belonging to the technical field of ecological environmental protection and restoration of a watercourse bank slope. The method provides a series of culture integration technologies such as a picking and storage method of phalaris arundinacea seeds, a selective criterion of a vinegar residue matrix, a sowing date determination principle, sowing density, a sowing method and irrigation and fertilization management after sowing. With the adaptation of the integration technologies, the acidity and the basicity of the ecological concrete are significantly improved, the growing time of the phalaris arundinacea before a next-year wet season is prolonged, the proportion of planting the phalaris arundinacea in gaps in the concrete spheres is increased, the vegetation coverage reaches over 100 percent, and the averagebiomass can reach 1.36kg / m<2> (dry weight above the ground). Moreover, the number of the phalaris arundinacea which is washed away is significantly reduced after the next-year wet season, and the vegetation is stable.

Description

Technical field: [0001] The invention relates to a technique and a method for constructing vegetation on a river bank sphere ecological concrete slope protection, and belongs to the technical field of river bank slope ecological environment protection and restoration. Background technique: [0002] Ecological concrete is a new type of concrete, which originated in Japan in the 1990s and has since been widely used around the world. In recent years, my country has made some progress in the research and application of this field. In terms of form, ecological concrete components mainly include spherical or hemispherical blocks, lattice blocks and stone-like blocks, etc., but they are all continuously cast by mixing and pouring coarse aggregate, cement, water and admixtures. Porous honeycomb blocks. However, due to the strong alkalinity of Portland cement as a cementitious material, the pH of the liquid phase in the voids in the concrete is generally as high as 12 or more, whic...
