Method for raising seedlings in plugs by cutting

Abstract

The invention discloses a method for raising seedlings in plugs by cutting. The method is suitable for cutting propagation of Chinese rose, camellia japonica, rhododendron,rosa rugosa and taxus chinensis. The method mainly comprises the following steps of (1) preparing a cutting shoot, namely selecting annual semi-lignified branches; (2) preparing a cutting plug, namely clipping a thin non-woven fabric to coat vermiculites in holes of the plug; (3) conducting cutting, namely removing leaves from the cut branches, and inserting the branches into the plug; (4) conducting watering; and (5) coating a film. The method is simple and feasible in operation, does not need hormone treatment, has a short rooting time, is suitable for large-scale industrialized seedling raising of Chinese rose, camellia japonica, rhododendron,rosa rugosa and taxus chinensis, and has broad-spectrum adaptability.

Description

technical field [0001] The invention belongs to the technical field of plant cutting seedling breeding and propagation, and in particular relates to a method for plug cutting seedling raising. Background technique [0002] Chinese roses, camellias, rhododendrons, and roses are all famous ornamental plants. Not only can it be used as potted flowers, but it can also be used for solitary planting, group planting and rockery landscaping in garden landscape construction, and can also be used for urban public greening, courtyard greening, flower exhibitions, fresh cut flowers and flower arrangement materials, etc. Taxus chinensis is a unique Tertiary relic plant in my country, and it is an important resource plant integrating ornamental, medicinal and timber uses. Since the 1970s, the natural anti-cancer product paclitaxel was extracted and isolated from Taxus brevifolia. Taxus, as an important medicinal plant, has been recognized more and more for its medicinal value. But most ...

Problems solved by technology

The Chinese invention patent with the publication number CN104604466A "A Method for Cutting Rose Branches" includes seedbed preparation, cutting preparation, cutting and post-cutting management and transplanting. The cutting seedbed is sandy loam soil with rich nutrition and ventilation and The soil improver is used as the cutting substrate; the cuttings are the semi-lignified branches of the year, and the cuttings and seedbeds are treated with growth regulators; the rooting rate of the small arched shed reaches 80% and then transplanted; when transplanting, open holes for planting, put Plantar fertilizer; the disadvantage of this method is that it is inconvenient to transplant

The Chinese invention patent with the publication number CN103960006A "A Rose Cutting Method" includes the preparation of cuttings, the configuration of cutting nutrient solution, and the production of fast cuttings. The cutting seedbed is flower mud, and nutrient solution needs to be configured for cutting , adding antibiotics to the nutrient solution to control the invasion of pathogens to the cuttings; the disadvantage of this method is that it needs to cut flower mud, regularly add nutrient solution and antibiotics to pollute the environment, etc.

Published patent application number CN103975737A's Chinese invention patent "Cultivation method of yew cuttings" includes the selection of branches in spring; soaking in root powder solution for 12 hours, the survival rate of cuttings can reach 90%. The disadvantage of this method is mainly to select cuttings Due to seasonal restrictions, cuttings need to be treated with root-promoting agents for a long time

Published patent application number CN101861792A's Chinese invention patent "A Mandia Taxus Cultivation Technology" includes selecting branches with a diameter of 5-10 cm and a diameter of 3-5 cm; After 48 hours of acetic acid treatment, the cuttings are mixed in perlite: humus at a ratio of 1:2 and then mixed with 30‐80g / kg of substrate. The survival rate of cuttings can reach 90%. The disadvantage of this method is that cuttings It takes a long time and the mixing matrix is ​​too troublesome

So far, there is no report on the successful application of a fast, simple, hormone-free, pre-treated cuttings, and a wide-ranging method for plant cutting propagation
