Method for constructing schima superba and sassafras mixed forest in coastal hills in Zhejiang

The invention discloses a method for constructing a mixed forest, and particularly relates to a method for constructing a schima superba and sassafras mixed forest in coastal hills in Zhejiang, which comprises the following steps of: keeping and cultivating 30-60 sassafras seed trees with excellent quality and strong plants per hectare on a slash; one-year-old schima superba is planted at the plant row spacing of (1.5-1.8) m * 1.8 m; natural updated common sassafras seedlings are reserved and bred on the forest land between the Schima superba plant row spacing outside the projection range of the common sassafras seed tree crowns; through young forest tending and forest stand management, the target tree density per hectare reaches 105-135 schima superba and 60-75 common sassafras respectively. According to the method, by means of biological characteristics of seed source providing, time difference of tree growth and the like of seed trees of the sassafras, dense crowns of schima superba can shade sun for the s
