Abstract
The invention provides a preparation method of afforestation matrices for mudstone rock slopes. The afforestation matrices are prepared by effectively compounding the raw materials such as gangue, mudstone rocks, ripened soil, a microbe improver, straws, cake fertilizers, livestock and poultry manures, binding agents, polyacrylamide or polyvinylmide and fertilizers under certain conditions. The method has remarkable effects of boosting soil forming and ripening of the matrices, increasing the supply of available nutrients of soil, improving the physical and chemical properties of soil and promoting revegetation.
Description
Technical field
The present invention relates to afforesting matrix, refer to especially a kind of preparation method of afforestation matrices for mudstone rock slopes.
Background technology
In the engineering constructions such as the constructing road in mountain area, hydroelectric development, mining, because slope excavation has caused a lot of exposed mud stone rock slopes.Mud stone is a kind of sedimentogeneous rock that is formed by mud and clay curing, and comparison of ingredients is complicated, and bedding is not obvious, is formed by fine grain settling.The mud rock geology condition has extensive distribution in China, belongs to soft rock mass, and mud stone has features such as meeting cement, softening and dehydration cracking.The rock slope surface of a wound is different from soil-slope, do not have the necessary edaphic condition of plant-growth and a nutrient condition, its rock mass water retaining function is poor, and the activation nutrient that contains is low, be difficult to from the side slope rock stratum, absorb moisture and nutrient supply growth and development of plants, cause plant to be difficult to existence.Therefore, the high-quality and efficient afforesting matrix of exploitation is the important substance basis (such as Chinese patent ZL02104143.1) of rock slope soil remediation and Revegetation.Yet, in the present known rock slope afforesting matrix process for preparation, not only the unreasonable application because of the microorganism modifying agent brings some detrimentally affect to matrix microbial ecosystem and physicochemical property, and also causes wasting of resources phenomenon serious because of a large amount of interpolations of peat.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of afforestation matrices for mudstone rock slopes, the deficiency that exists to overcome prior art, have draw materials conveniently, the characteristics such as with low cost, resources conservation, environmental friendliness.To the slaking of one-tenth soil, the supply that increases the available nutrient of soil that promote matrix, improve soil physico-chemical characteristic, promote that Revegetation has significant effect.The present invention has not only found a new approach that utilizes for the waste coal gangue in the progress of coal mining, and contain the characteristics of the nutritive elements such as more rich organic matter and P, K, Ca, Mg, S, Cu, Zn, Fe, Mn for coal gangue, practicablely turn waste into wealth, also provide a kind of new technology for preparing high-quality and efficient rock slope afforesting matrix.
