Cuttage propagation method for Juniperus horizontalis 'Bar Harbor'

Abstract

The invention discloses a cuttage propagation method for Juniperus horizontalis 'Bar Harbor' and belongs to the technical field of plant propagation. The method is characterized by comprising the following steps of: 1) filling peat, pulverized reed leaves, pearlite and an organic fertilizer in a volume ratio of (2-4):(3-5):(1-3):(0.5-1.5) which are taken as matrixes into a seedbed; 2) picking autumn tips obtained last year from female parents of the Juniperus horizontalis 'Bar Harbor' and cutting spikes, wherein the appropriate cuttage time is early March; 3) impregnating ear bases of cottage branches for 2 to 3 seconds by using a Sensheng No.5 plant root promoter at the concentration of between 180 and 220ppm; 4) performing cuttage by using the seedbed, and entering a management and maintenance stage; and 5) performing seedling hardening when the rooting rate reaches about 90 percent. By the cuttage propagation method for the Juniperus horizontalis 'Bar Harbor', the rooting condition is good, and the yield can reach over 93 percent; and the method is high in propagation speed, can adapt to climate and soil environments in China, and has good market prospect, and the propagation operation steps are simple.
