The invention provides a soil loosening and recarburization conditioner for a torreya grandis forest. The conditioner is prepared from, by weight, 5-10% of straw, 20-30% of a cake fertilizer, 20-40% of undecomposed livestock manure, 5-20% of rice chaff, 5-20% of saw dust, 5-20% of ceramsite and 10-20% of river sand, wherein 5-10% of the straw comprises one of more of rice, millet and corn stalk; 20-40% of the undecomposed livestock manure is livestock manure fermented for 30-40 days; 10-20% of the river sand is dried river sand. The soil loosening and recarburization conditioner for the torreya grandis forest has the advantages that the undecomposed livestock manure is added into the conditioner, therefore, when the conditioner is released into the roots of torreya grandis, the conditionercan continue to decompose on the root, and the generated heat can increase the diffusion efficiency of water, gases and exchange ions and microbial activity in the soil and can improve the growth ofthe roots of the torreya grandis; generated carbon dioxide can effectively improve the photosynthesis of torreya grandis trees and promote the growth of the torreya grandis.
