China is one of the countries on coal as its main energy in the world, a large amount of fly ash output. At present, China's handling of fly ash gray field storage as the main means not only take up a lot of land, but can easily cause environmental pollution. At the same time, another industrial waste furfural residue production with the development of modern industrialization gradually increased, most of the build-up or digging dumped treatment is not only a huge waste of energy, and will take up space, pollution soil and water. Therefore, the two waste comprehensive utilization of fly ash and furfural residue is an urgent research topic. The study found that, acidic substance furfural slag and fly ash mixture, the pH value of the fly ash can be reduced, and a high content of organic matter can improve the physical and chemical nature of the fly ash, while reducing the hazards of toxic elements in fly ash, pulverized coal gray practical modified materials, fly ash and furfural residue mixed material as possible to Agricultural Growing Media. The study found both suitable and appropriate mixing ratio pioneer plant, but only mixed matrix group with the nature of the early pioneer plant, to this mixed matrix into the implementation of this matrix The long-term change in the nature and suitable for plant diversity further research. In this study, as many plants to test, analyze the physical and chemical properties of the mixed matrix by more than three years of continuous observation, comparison plant yield, quality, and explore the impact of harmful heavy metals in the mixed matrix of plants and the environment, and evaluate the quality of the matrix analysis matrix difference in quality compared with the crop soils, provide the basis for the implementation of the matrix field. The results show that: (1) fly ash and furfural residue 4:1 mass ratio of the group with the new matrix for plant cultivation, initially to meet a part of the growth of salt-tolerant plants, after a certain period of plantation management, mixed matrix properties be improved to meet the vast majority of plant growth requirements. (2) the beginning of the mixing matrix suitable for alfalfa, rose, ryegrass, Kentucky bluegrass, tall fescue and other plant growth, but large than the control bit weak, spinach, green beans, millet is not suitable for cultivation in the matrix. Starting from the following year, the matrix to meet the growth requirements of the vast majority of test plants. Plant yield, quality as the matrix maturation gradually improved. The edible part of the main content of harmful heavy metals were not exceeded. (3) After a certain period of use of high concentrations of salt content in the matrix has a very significant decline, will not have an impact on plant growth, available nutrients are higher than the level of medium fertility soil, abundant organic matter content, pH value close neutral, except Cd, several major heavy metals concentrations do not exceed the soil environmental quality standards two values, and reached general farmland environmental quality standards. (4) matrix concentration of the leaching solution, chromium, lead, cadmium, copper, zinc, arsenic and several heavy metal elements
