Cutting seedling method for dracontomelon duperreanum greening tree species

Abstract

The invention belongs to the technical field of propagation of greening tree species and discloses a cutting seedling method for dracontomelon duperreanum greening tree species. The method comprises the following steps: selecting twigs in January, April, July and November for cuttage, wherein spikes are separately 6cm, 10cm and 14cm in length; quickly dipping the spikes with 200mg/L, 400mg/L and 600mg/L rooting agents, and mixing sandy loam and subsoil (the mass ratio is 1:1) as a cutting matrix; and covering and overshadowing the spikes with films, opening the films to spray water, and applying fertilizers after rooting. The cutting survival rate of dracontomelon duperreanum reaches 80% or higher.
