Problems solved by technology

Although the invention classifies the mother seedlings after the seedlings are raised, the seedlings germinated from the seeds have a large difference in growth. After classification, some materials with weaker growth will not be able to be cut off, resulting in ineffective investment in the early stage. There are certain limitations in use

Abstract

The invention discloses a plant propagation method. The plant propagation method comprises the steps of selecting a rooting-germination accelerating treatment site on a non-isolated root system of a plant, and then carrying out cutting treatment or / and hormone treatment on the rooting-germination accelerating treatment site. According to the plant propagation method, the non-isolated root system is used as a material for propagation, and a large number of young individuals with the same genotype as mother plants can be obtained; moreover, the method is low in cost and easy to operate, a physical and chemical combined method is adopted, propagated individuals share mother plant root systems to absorb nutrients, the survival rate is high, plants are robust, management is almost not needed before transplanting, newly-grown seedlings have independent root systems, the mother plant root systems do not need to be cut off during transplanting, the influence of conventional root cutting on themother plants is avoided, and the problem that tender individuals with the same genotype as the mother plants are difficult to quickly obtain in scientific research and production is solved.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for asexual propagation of shallow-rooted plants, and belongs to the field of garden plants. Background technique [0002] The germination promotion of trees is widely used in the construction of ear picking gardens and rapid vegetative propagation. At present, asexual reproduction methods such as tissue culture, grafting, root cuttings and cuttings are mostly used in seedling cultivation and plantation. Although the purpose of rapid reproduction can be achieved, there are respective limitations in the above several methods. Tissue culture has high requirements on the operating environment and the quality of operators, and the initial investment is large. The survival rate is difficult to guarantee. Different breeding materials need a corresponding set of breeding systems, and it is difficult to directly promote and utilize them in production. Grafting and ...
