Preparation method for cutting rooting agent used for oriental arborvitae

Abstract

The invention discloses a preparation method for a cutting rooting agent used for oriental arborvitae. The preparation method comprises three steps, i.e., preparation of tender willow juice; compounding; and preparation of the rooting agent. The preparation method comprises the following concrete steps: firstly cutting tender willow branches short, incising the short tender willow branches, and carrying out submerged soaking so as to obtain the tender willow juice; then dissolving polyaspartic acid, rice vinegar, the tender juice, potassium 3-indolebutyrate, aspirin, sucrose and 3-bromocamphor-8-sulfonic acid in distilled water, and slowly adding indoleacetic acid, 2-diethylaminoethyl hexanoate, salicylic acid, pullulan and naphthaleneacetic acid so as to obtain a rooting agent solution; and slowly adding the rooting agent solution into a carboxymethyl chitosan solution drop by drop and carrying out uniform mixing so as to obtain the rooting agent. The invention has the beneficial effects that the preparation method for the rooting agent is simple and easily practicable; the biological effect of growth hormones in the rooting agent can be effectively preserved; and the rooting agent also has the functions of sustained release, transpiration prevention and water loss pverntion, and can promote rooting and improve a survival rate.

Description

technical field [0001] The invention relates to the field of plant propagation, in particular to a preparation method of a cutting rooting agent for arborvitae. technical background [0002] Arborvitae is an evergreen tree. The crown is broadly oval, and the branchlets are flat, arranged in a plane. The leaves are small and scale-like, clinging to the branchlets in a cross-opposite arrangement, with glandular grooves in the middle of the back of the leaves. Plants monoecious, flowers unisexual. The male cones are yellow, composed of alternating microsporophylls, each microsporophyll has 3 anthers, and the pearl scales and bract scales are completely healed. The cones are mature in the same year, the scales are lignified, cracked, and the seeds have no wings or ridges. Arborvitae is a special product in China, and it is distributed all over the country except Qinghai and Xinjiang. The life span is very long, and there are often ancient trees with a hundred years or more....

But this inventive method treats cuttings with 600-4000 mg / L naphthalene acetic acid and indole butyric acid as hormones, and its concentration greatly exceeds the suitable concentration. High concentration auxin will interfere with the normal protein and nucleic acid metabolism process of cuttings, thereby making the body grow Slowing down or even stopping will cause dead seedlings, and its auxin will be decomposed by photooxidation, which will cause the cuttings to suddenly contact with a large concentration of auxin in the initial stage, resulting in slow growth of the body, and there is no auxin available in the later stage, so the inventive method The survival rate of cuttings is not high
