Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Embodiments of the invention include:

[0021] A method for cutting and propagating red shin scattered leaves, comprising the following specific steps:

[0022] Step 1. Configure the initial induction medium and rooting agent: use a solution with a sucrose concentration of 8%, agar content of 0.7%, and a pH value of 5.6-5.8 as the initial induction medium; use NAA (naphthaleneacetic acid) 400-800mg, vitamin B 1 2-5mg, 20-50g of sucrose, 3-6g of borax and 1kg of water are used to make a mixed solution as a ro...

Abstract

The invention relates to a leaf cutting propagation method for Polygonum runcinatum. The method comprises specific steps as follows: S1, preparing an initial induction culture solution and a rooting agent; S2, initial induction culture; S3, induction of callus; S4, value-added culture; S5, seedling hardening and transplanting. By means of the leaf cutting propagation method for Polygonum runcinatum, a large quantity of cutting materials can be saved, growth of original plants is not affected, and time and labor are saved during leaf picking.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation methods, in particular to a propagation method of Chishan scattered leaf cuttings. Background technique [0002] Chishan powder (Polygonum runcinatum in Latin) is a herbaceous plant of the genus Polygonum, mainly produced in Sichuan, Guizhou, Yunnan, Hunan, Hubei, Shaanxi, Gansu and western Henan. It is suitable for arranging flower borders, roadsides or planting under sparse forests. [0003] Chishan powder has remarkable resistance and enrichment characteristics to heavy metals cadmium, zinc, lead and copper. Phytoremediation has developed new varieties of plant resources. [0004] Chishan powder is often propagated by division and seed, mainly by division. The traditional method is to dig up the rhizome before emergence and divide it into individual plants. When planting, plow the land and open a 1.3m wide high bed. The distance between the plants is about 33cm and the h...
