Syzygium buxifolium cutting propagation method

Abstract

The invention relates to a syzygium buxifolium cutting propagation method, and belongs to the technical field of plant propagation. The method comprises the following steps that 1, proper propagation land is selected to build a syzygium buxifolium female parent cutting orchard; 2, a 72-hole plug tray is filled with a substrate; 3, proper cutting time is early September or mid-September, and cutting is conducted once a year; 4, cutting branches adopt scions soaked with a root promoting agent; 5, about 95% of the scions are rooted in 38 days after cutting, and seedling exercising can be conducted. The syzygium buxifolium cutting propagation method is easy to operate and high in propagation speed, the problem that syzygium buxifolium cutting propagation rooting is difficult is solved, the yield is up to 95%, the syzygium buxifolium cutting propagation method can be used for commercialization large-scale production, is good in repeatability and is reported for the first time at home, and the gap of the related technical field at home is filled up.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, in particular to a cutting propagation method of red nan. Background technique [0002] Syzygium buxifolium, Myrtaceae, Syzygonia genus, evergreen broad-leaved shrub, with ridged shoots, oval, spherical crown, tough wood, bark tea brown, reddish brown, not smooth, dense branches, many branches, Twigs brittle and easy to break; single leaves, opposite, small, leathery, broadly elliptic, elliptic, broadly obovate, nearly oblanceolate, 1.5-3cm long, 1-2cm wide, cuneate at the base, blunt at the apex , entire margin, pinnate veins, main veins are sunken, side veins are small and inconspicuous, numerous and dense, with a pulse distance of 1-1.5 mm, obliquely upwards, 1-1.5 mm away from the edge of the leaf to form lateral veins, and the leaves are short The stalk is about 2mm long, and the new buds and leaves are red in spring, which are ornamental, and the leaves are green and yellow-green...

AI Technical Summary

Problems solved by technology

At present, the cutting propagation technology of red nan is still immature, and the rooting rate of the existing spikes is only about 70%, and Liu Wei et al. (2009) believe that seed propagation is easier than cuttings, and the reproduction coefficient is higher

However, the genetic background of the seeds is complex, and large-scale propagation of seeds is not conducive to the consistency of the product, which restricts the professional and large-scale development of red Nan.
