Method of single-bud cutting propagation of film-covered rose

Abstract

The invention provides a film-covered Chinese rose single bud cutting propagation method. The film-covered Chinese rose single bud cutting propagation method comprises the steps of paving a bottom-layer plastic film on a flat seedbed and paving geotechnical cloth on the plastic film, putting a sterile coconut chaff seedling substrate on the geotechnical cloth and thoroughly watering the substrate, selecting Chinese rose branches, dipping the roots of the cuttings with 3-indolebutyric acid rooting powder having the content of 0.10%-0.25%, inserting the cuttings into the substrate and thoroughly watering again, covering the seedbed with the cuttings with a layer of non-woven cloth, covering the non-woven cloth with a top-layer plastic film and wrapping the bottom-layer plastic film and the top-layer plastic film together, controlling the outside environmental temperature of the cutting seedbed within the range of 20-32 DEG C before rooting, after the Chinese rose cuttings root completely and the cutting auxiliary buds begin to germinate and grow, uncovering the top-layer plastic film, uncovering the non-woven cloth 2-4 days later, and performing intermittent spraying watering to ensure that the substrate is wet thoroughly until the seedlings are grown. The film-covered Chinese rose single bud cutting propagation method has the advantages of isolation of the seedling substrate from the outside environment, few cutting diseases, high survival rate, quick seedling growing, simple planting management and low labor investment.

Description

technical field [0001] The invention belongs to the technical field of vegetative propagation of horticultural plants, and relates to a film-covered rose single-bud cutting propagation method. Background technique [0002] Cuttings are an important method of asexual reproduction of plants. Using part of the roots, stems or leaves of plants, the cuttings take root and grow into complete and independent new plants. Cutting seedlings have the advantages of simple propagation method, convenient management, and fast seedling growth. Cutting seedlings can be collected when the plants are pruned, and the production cost is relatively low. In practical application, the cutting propagation of plants mainly includes branch cuttings and root cuttings. According to the nature of cuttings, cuttings are divided into hard branch cuttings and tender branch cuttings. The basic principle of cutting is: under suitable conditions, the cambium at the base of the cuttings will first form a white...

Problems solved by technology

However, in practical application of this method, the environmental humidity control is relatively strict with the change of weather, and automatic intermittent spraying during the day is required, resulting in a large waste of water resources, difficulty in personnel monitoring and management, poor rooting consistency of cuttings, and survival of seedlings. The rate cannot reach the best effect, which affects the efficient reproduction and production of rose seedlings
