Embodiment 1
[0030] A soil improvement and detection method for saline-alkali land and desert, including a soil improvement method and a soil detection method, wherein the steps of the soil improvement method are as follows:
[0031] 1) Solid-liquid separation of kitchen waste, crushing of agricultural and forestry wastes, dewatering of river sludge and municipal sludge;
[0032] 2) Mix 60 parts of kitchen waste, 10 parts of agricultural and forestry waste, 30 parts of river sludge and municipal sludge treated in step 1), add activated carbon and hydrogen peroxide for composting and fermentation, hydrogen peroxide disinfection, activated carbon to remove part of the odor, activated carbon The mass percentage of the mixture with hydrogen peroxide is 5%;
[0033] 3) The compost fermentation product 1 in step 2) is compressed and dewatered, and the compost fermentation is carried out again to keep its temperature at 50°C. When the temperature exceeds 50°C, a soil tiller is used to turn the he...
Embodiment 2
[0048] In step 3) of the soil improvement method, the mixing mass ratio is: 40% of kitchen waste, 20% of agricultural and forestry waste, 40% of river sludge and municipal sludge, and the mass percentage of activated carbon and hydrogen peroxide in the mixture is 10%; step 5) The temperature of re-composting fermentation in the medium was maintained at 70°C.
Embodiment 3
[0050] In step 3) of the soil improvement method, the mixing mass ratio is: 50% of kitchen waste, 15% of agricultural and forestry waste, 35% of river sludge and municipal sludge, and the mass percentage of activated carbon and hydrogen peroxide in the mixture is 8%; step 5) The temperature of re-composting fermentation in the medium was maintained at 60°C.
[0051] The invention can make the soil change from weakly alkaline to weakly acidic which is more suitable for plant growth, and also significantly improve the salinity leaching rate of the soil and the germination index of plants, which is beneficial to the growth of plants, and obviously improves the quality of the original soil. It can realize the harmless and resourceful treatment of kitchen waste, and realize the effective utilization of waste resources.
