Elm cutting propagation method

Abstract

The invention relates to an elm cutting propagation method. The method comprises the following steps: 1) in mid February, collecting and processing annual shoots of an elm; 2) cultivating the disinfected cutting shoots in a culture room until yellowish calluses grow from incisions in the bottoms of the cutting shoots after one week; 3) taking out the calluses from the cutting shoots, and carrying out rooting treatment and germinating agent treatment; 4) through the above treatment, removing other lateral buds of the cutting shoots and keeping top buds when the buds of the cutting shoots begin to germinate after one week and new leaves gradually sprout; and 5) transplanting when branch roots are formed after cultivating for 25 days. The cutting propagation method disclosed by the invention realizes the full use of slack winter season and avoids busy spring, and the method provides longer growth time for seedlings.

Description

technical field [0001] The invention relates to a method for promoting rooting of cuttings in the process of plant asexual propagation, especially in the process of cutting propagation, in particular to a hydroponic cutting propagation method of elm. Background technique [0002] Cutting is a common propagation method for cultivating plants. The roots, stems, and leaves of plants are inserted into soil, sand or soaked in water, and then planted after rooting to obtain an independent new plant. In forestry production, different plants have different conditions for cuttings. For example, the location of the material, the time of cuttings, and the cutting substrate will all affect the survival rate of cuttings. In terms of production, twig cuttings can effectively multiply elms. However, the cutting time of twigs is the growth period of seedlings from June to August. Before the cutting of twigs is completed, it is necessary to reserve a long period of land for transplanting se...

Problems solved by technology

The hard branch cutting technology of elm is currently in the initial stage of experimentation, and the cutting technology is immature, mostly preliminary exploration, and multi-use land, such as Yang Yanli's "Preliminary Study on the Hard Branch Cutting Experiment of Golden Leaf Elm"; Li Min's "Bai Yu Cutting Propagation Experiment", etc. On the land or in the culture medium, but affected by the weather, the survival rate cannot be guaranteed
