The invention discloses an EPS composite rock surface repair matrix, which is composed of raw materials in subordinate mass ratios: 3-4 parts of sodium carboxymethyl cellulose, 40-60 parts of coconut bran, and 0.1-0.3 parts of ammonium dihydrogen phosphate. parts, 25-35 parts of sterile water, and 60-80 parts of high-viscosity EPS; described high-viscosity EPS is that 1 mass part of bacteria content is the phosphate solubilizing bacteria strain PMN1501 fermentation broth of 1 × 10 cells/g put into It is produced after fermenting 500 parts by mass of straw powder extract medium for 16h-26h. The present invention utilizes discarded coconut bran as a material, can effectively utilize waste, provides a new utilization approach for the utilization of coconut bran, and at the same time, the present invention can improve the absorption and utilization rate of fertilizer nutrients by plants, and can reduce the amount of chemical fertilizer and reduce The effect of soil compaction. |
