Wormcast-based transplanting matrix for improving survival rate of osmanthus seedlings and use method thereof

The invention discloses a wormcast-based transplanting matrix for improving a survival rate of osmanthus seedlings and a use method thereof. The transplanting matrix is obtained by mixing wormcast with Yangtze River alluvial soil according to the volume ratio of (9: 1)-(3: 7). After transplanting for 40 days, the survival rate of osmanthus trees using the prepared matrix is up to 100%, and the osmanthus trees start to grow shoots after 43 days; while the survival rate of the osmanthus threes using Yangtze River alluvial soil as control is only 36%, and the shoots do not appear yet after 100 days.
