Cutting Propagation Method of Rhododendron orientalis in High Temperature Area in Summer

Abstract

The invention discloses a cutting propagation method of Japan cuckoo in a summer high temperature area, which includes selection of cuttage period; cuttage seedbed preparation; selection and shearing of cutting slips; pretreatment of cutting slips; cutting and management after cutting. Through adjustment of the cuttage period, the selection and special treatment of rooting liquid, cutting matrix and cutting slips, strict control of cuttage environment, selection of cutting slips with big degree of lignification, and use of a double-layered arched shed film and a sunshade net, the method can preserve humidity and reduce temperature, thus the success rate of the cutting propagation of Japan cuckoo in the summer high temperature area is greatly improved. The method effectively solves the difficulty that the Japan cuckoo is not easy to take root after cutting in the summer high temperature area, the cutting slips are easy to die, and the cutting propagation rate is low; the rooting rate and quality are effectively increased; the rooting rate is up to over 95%.

Description

technical field [0001] The invention belongs to the technical field of rhododendron propagation, and in particular relates to a cutting propagation method of Rhododendron orientalis in summer high-temperature regions. Background technique [0002] At present, the existing horticultural rhododendron cultivars in China are generally accepted to be classified according to the flowering period and source, and are divided into four strain groups: Spring Rhododendron, Summer Rhododendron, Eastern Rhododendron and Western Rhododendron (Zhang Changqin 2008). [0003] Rhododendron obtusum (oriental cuckoo for short) refers to a variety of Rhododendron obtusum from Japan and its many hybrid offspring. The plant of Rhododendron obtusum is low, and its branches are mostly horizontal, small and soft. The leaves are tender green, shiny on the surface, oval in shape, smaller, thinner, and less hairy. The flower buds are born on the top of the branches. Generally, there are 1-3 small flowe...
