The present invention provides a method for soil improving in red loquat planting process, and relates to the field of agricultural planting, the method includes the steps of land selection, land preliminary treatment and soil improvement, and a soil conditioner comprising the raw materials of 150-200 parts by weight of domestic sludge water, 30-40 parts by weight of crop straws, 10-20 parts by weight of livestock manure, 5-8 parts by weight of vinasse, 1-2 parts by weight of Hydromica, 1-2 parts by weight of probiotics and 0.5-1 part by weight of a composite modifier to complete the soil improvement. The domestic sludge water, the crop straws, the livestock manure, the vinasse and other cheap waste raw materials are used as the main materials of the soil conditioner, animals are used forsludge treatment, useless domestic sludge is converted into a beneficial pure natural organic fertilizer by the ecosystem in the body of the animals, side effects can be avoided, the probiotics and the composite modifier are added for catalysis of the soil improvement, the soil conditioner used in the soil improvement has higher efficiency, and results can be guaranteed.
