Problems solved by technology

[0003] A large amount of organic matter (sawdust, rice husk, distiller's grains) and artificial inorganic fertilizers are added to the vegetation concrete slope protection technology. As the vegetation grows, artificial inorganic fertilizers are used first, and a large amount of organic matter has not been decomposed in time to provide subsequent Nutrient elements, which cause the vegetation to slow down in the growth process in the following two or three years

Embodiment Construction

[0019] The implementation process of this method is as follows:

[0020] 1. Preparation of activator:

[0021] Combined with the soil texture of the construction site, mix 20-35Kg of nitrogen-fixing bacterial fertilizer, phosphate-solubilizing bacterial fertilizer, also known as phosphorus-resolving microbial fertilizer 1-5Kg, and silicate bacterial bacterial fertilizer, also known as biological potash fertilizer 60-84Kg, and then add water. The mixture was adjusted into a paste, then 5% sucrose solution was added, soaked for activation for two hours, and then freeze-dried to obtain a powdery activated product.

[0022] Mixing 90-110Kg of concrete greening additive, 180-220Kg of organic matter, 180-220Kg of cement, and 0.04-0.06Kg of activator fully and uniformly to obtain activation additive material;

[0023] The obtained activation additive material is added to the soil, so that every 1 cubic meter of soil contains 40-60g of concrete greening additive. After fully stirring...

Abstract

A vegetation protective soil base material activation method is applied to the fields of ecological slope protection project, ecological restoration project and side slope and landscape garden greening project and the like. The method includes that concrete greening additive, organic matter, cement and activation substance are fully mixed to be uniform and then mixed into soil base material, and a spraying and sowing machine is adopted to spray activation substance on side slope finally, wherein the activation substance is obtained by combination and activation of three microbial inoculum fertilizers of nitrogen-fixing microbial inoculum fertilizer, phosphate-dissolving microbial inoculum fertilizer and silicatebacterium fertilizer. The vegetation protective soil base material activation method provided by the invention provides growth environment for plants in concrete and is beneficial to side slope greening plant growth. Meanwhile quantity of microorganism in slope protection base material is increased, and soil nutrient activation speed is improved by utilizing decomposition of microorganism on organic matter and release action of microorganism on mineral element, thus improving soil aggregate, improving soil fertility and effectively promoting side slope restoration.

Description

technical field [0001] The invention relates to the technical field of slope greening, in particular to a soil substrate for vegetation protection, which is applied in ecological slope protection projects for the purpose of improving the characteristics of vegetation protection substrates, enhancing the fertility of the vegetation protection substrates and improving the growth environment of vegetation on slopes. method of activation. Background technique [0002] At present, domestic infrastructure is developing rapidly. Infrastructure construction such as hydropower development and road construction makes slope excavation and ecological protection projects everywhere. For example, the greening technology of vegetation concrete slope protection has been widely promoted in my country. This method has high technical content. The patented product - greening additive is used to make the spray layer have good structure and nutritional conditions, and the pH value is controlled w...
