Abstract
The invention discloses a compound substrate for cultivating lawns and a preparation method thereof. The substrate is prepared by taking mineralized refuse as a main component, sufficiently curing the mineralized refuse and hogwash refuse and then mixing a mixture with greened soil, coal ash or desulfurized gypsum; the prepared compound substrate can be used for replacing common greened soil to produce the lawns. According to the compound substrate, on one hand, a recycling way of four wastes including the mineralized refuse, hogwash, the coal ash and the desulfurized gypsum is expanded; on the other hand, the production cost can be saved so as to be good for solving the problems of damages to the soil, soil salinization and the like in the production of conventional lawns in China.
Description
Technical field
The present invention relates to the matrix of culturing plants, specifically belong to a kind of composite interstitial substance of cultivating lawn and preparation method thereof.
Background technology
Mineralized waste be domestic refuse in refuse landfill after landfill is for many years stable, a kind of soil-like grain material of formation.In mineralized waste, contain the required nutritive substance of a large amount of plant-growths and trace element, the cultivation of using it for lawn is feasible, but due to physical structure, the physico-chemical property of former mineralized waste and other pollution substances that contain, the grow generation restraining effect of meeting to plant, therefore, directly utilize former mineralized waste production lawn not reach desirable effect, the quality that must produce through improvement guarantee lawn.
Flyash is the waste residue that coal-fired station produces under hot conditions, wherein contain nutritive element and the trace elements such as the required Mg of a large amount of plant-growths, P, K, flyash adds in mineralized waste as mineralized waste modifying agent, can promote the growth of plant, increase the biomass of plant, also can change the physico-chemical property of mineralized waste, improve the fertility of mineralized waste simultaneously.
Desulfurated plaster is the by product that the flue gas that produces after coal combustion obtains after desulfurization is processed, wherein contain abundant plant essential mineral element S, Ca, Si etc., desulfurated plaster and organic mixing modifying agent can improve the physical structure of mineralized waste, total porosity, the increase hollow billet space that can reduce mineralized waste capacity, increase mineralized waste, reduce non-hollow billet space.The chemical ion that can improve mineralized waste simultaneously forms, and reduces the total salt quantity of mineralized waste.
Summary of the invention
The object of the present invention is to provide a kind of composite interstitial substance of cultivating lawn and preparation method thereof, this composite interstitial substance can replace afforesting autochthonal product lawn not only can, by mineralized waste resource utilization, can also save the land resources of China.
A kind of composite interstitial substance of cultivating lawn provided by the invention, is to take mineralized waste as main body, adopts multiple modifying agent that mineralized waste is improved and formed, and its components in mass portion is counted meter: mineralized waste 100, hogwash 10-30, afforests native 10-30.
Described greening soil replaces with flyash or desulfurated plaster.
A kind of composite interstitial substance of cultivating lawn provided by the invention, components in mass portion is counted meter: mineralized waste 100, hogwash 10-30, flyash 10-15, afforests native 10-15.
Described flyash replaces with desulfurated plaster.
A kind of preparation method who cultivates the composite interstitial substance on lawn provided by the invention, step comprises: after first mineralized waste and hogwash evenly being mixed and become thoroughly decomposed by said components proportioning, then mix with remaining component.
Above-described becoming thoroughly decomposed is that pretreated former mineralized waste and hogwash are banked up about 30 days 25 ℃ of left and right.
Prepare after matrix, before turf plant, to the matrix infiltration of will repeatedly spraying water, guarantee that the moisture in matrix is sufficient.The lawn maintenance in its later stage carries out according to ordinary method with irrigation.
Compared with prior art, advantage of the present invention:
The present invention utilizes mineralized waste, hogwash, flyash, the multiple waste of desulfurated plaster as the matrix of cultivating lawn, find an approach that rationally utilizes multiple waste, utilize turf quality that the present invention produces to be better than the lawn of the autochthonal product of common greening, so the present invention can replace greening soil completely and cultivate lawn.Mineralized waste after improvement comes production lawn can greatly solve a large amount of farmlands soil destruction problem that lawn production brings as Nutrition Soil, can realize the circulation sustainable use of refuse landfill simultaneously, to saving China's land resources, has great significance.
