Cutting Propagation Method of Rhododendron by the Stream

Abstract

The embodiment of the invention discloses a cutting propagation method of rhododendron rivulare. The method comprises the following steps: performing site preparation; selecting and scissoring cuttings; treating the cuttings; performing cuttage and cuttage post-management. Specifically, the method comprises the following steps: selecting 3-5-year-old rhododendron rivulare as a mother plant, scissoring annual half-lignified branches as cutting materials, cutting the cutting materials into cuttings of 8-10 cm, keeping 3-4 knots for each cutting, and remaining 3-4 complete leaves at the top of the cutting; cutting a part of the top of the cutting, 0.5 cm away from a bud to be flat by a sharp edge, and cutting away a section with the length of 0.5 cm at a part of the base of the cutting, 2 cm away from the bud under the condition that the included angle between the sharp edge and the cutting is 45 degrees, wherein a cutting hole is horse-ear-shaped; cutting off 2 / 3 of each of the 3-4 complete leaves remained at the top of the cutting. According to the method, the difficult problems of difficult rooting and low cutting propagation rate of the rhododendron rivulare are effectively solved, the rooting rate can reach more than 82%, and the cutting rooting time is only 70 days; the method is an effective method for quickly propagating the rhododendron rivulare.
