Embodiment 1

[0023] In an embodiment of the present invention, a composite material for ecological restoration includes the following raw materials: 31 kg of apatite, 7 kg of tetraethyl orthosilicate, 15 kg of chitosan, 42 kg of ageratum, and 13 kg of tea polyphenols.

[0024] Grind the ageratum, pass through a 100-mesh sieve, and then add an acetic acid solution whose mass is 4 times that of the acetic acid solution. The solvent of the acetic acid solution is water, and the mass concentration of the acetic acid solution is 30%. Then the temperature was raised to 55° C., heated and stirred at this temperature for 50 minutes, and then ultrasonically treated for 15 minutes with an ultrasonic power of 1000 W. The filtrate was collected by filtration and concentrated to 10% of its volume to obtain the Ageratum treatment product. Mix ethyl orthosilicate with ethanol 4 times its mass to prepare ethyl orthosilicate solution; crush apatite, pass through a 100-mesh sieve, and mix with ethyl orthosil...

Embodiment 2

[0026] In an embodiment of the present invention, a composite material for ecological restoration includes the following raw materials: 39kg of apatite, 15kg of tetraethyl orthosilicate, 25kg of chitosan, 50kg of ageratum, and 21kg of tea polyphenols.

[0027] Grind the ageratum, pass through a 150-mesh sieve, and then add an acetic acid solution 5 times its mass. The solvent of the acetic acid solution is water, and the mass concentration of the acetic acid solution is 35%. Then the temperature was raised to 60° C., heated and stirred at this temperature for 60 minutes, and then ultrasonically treated for 20 minutes with an ultrasonic power of 1000 W. The filtrate was filtered and concentrated to 15% of its volume to obtain the Ageratum treatment product. Mix ethyl orthosilicate with ethanol 5 times its mass to prepare ethyl orthosilicate solution; crush apatite, pass through a 150-mesh sieve, and mix with ethyl orthosilicate solution at a stirring speed of 250r / min Stirred f...

Embodiment 3

[0029] In an embodiment of the present invention, a composite material for ecological restoration includes the following raw materials: 33kg of apatite, 9kg of tetraethyl orthosilicate, 18kg of chitosan, 44kg of ageratum, and 15kg of tea polyphenols.

[0030] Grind the ageratum, pass through a 150-mesh sieve, and then add an acetic acid solution 4.5 times its mass, the solvent of the acetic acid solution is water, and the mass concentration of the acetic acid solution is 35%. Then the temperature was raised to 60° C., heated and stirred at this temperature for 55 minutes, and then ultrasonically treated for 20 minutes with an ultrasonic power of 1000 W. The filtrate was filtered and concentrated to 15% of its volume to obtain the Ageratum treatment product. Mix ethyl orthosilicate with 4.5 times the mass of ethanol to prepare ethyl orthosilicate solution; crush apatite, pass through a 150-mesh sieve, and mix with ethyl orthosilicate solution at a stirring speed of 250r / min Sti...

Abstract

The invention discloses a composite material for ecological restoration as well as a preparation method and application thereof. The composite material is prepared from the following raw materials in parts by weight: 31 to 39 parts of apatite, 7 to 15 parts of ethyl orthosilicate, 15 to 25 parts of chitosan, 42 to 50 parts of ageratum conyzoides and 13 to 21 parts of tea polyphenol. The preparation method comprises the following steps of crushing the ageratum conyzoides, adding into an acetic acid solution, heating, agitating, carrying out ultrasonic treatment, filtering and concentrating, so that an ageratum-conyzoides treatment substance is prepared; crushing the apatite, mixing with an ethyl orthosilicate solution and heating, so that a mixture A is prepared; mixing the chitosan and a citric acid aqueous solution and heating, so that a mixture B is prepared; uniformly mixing and agitating the ageratum-conyzoides treatment substance, the mixture A, the mixture B and the tea polyphenol, so as to obtain the composite material. The composite material is used for improving the germination rate and the survival rate of a plant and the ecological restoration rate of mine, can be used for adsorbing a heavy metal, which cannot be free out, in soil, and can be used for effectively ameliorating the soil of the mining wasteland, the heavy metal polluted land, the hillside land and the like.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation, in particular to a composite material for ecological restoration and its preparation method and application. Background technique [0002] The irrational development and utilization of human beings has caused the destruction of natural ecological environments such as forests and grasslands, thereby deteriorating the living conditions of humans, animals, and plants; such as: soil erosion, land desertification, soil salinization, and biodiversity reduction, etc. Wait. The consequences of environmental damage often take a long time to recover, and some are even irreversible. The main ecological problems are as follows: In my country's serious soil pollution areas, the pollution area caused by excessive agricultural products is extensive, of which heavy metal pollution accounts for 80%. The excessive rate of heavy metals Pb, Cu, Zn, Cd and Cr in grain accounts for 10%; the parks...
