With the development of flower industry, miniaturized and compact potted flowers and bonsai are more and more popular, so the dwarfing technology of flowers shows more and more vitality. The main techniques of dwarfing cultivation are:

The main results are as follows: 1. asexual reproduction can achieve dwarfing effect by using grafting, cutting, striping and other asexual reproduction methods, which can shorten the flowering stage, reduce the plant height and compact the plant type. Grafting can achieve dwarfing by selecting dwarfing varieties. The plant height can be determined by considering the cutting time, for example, the chrysanthemum can be dwarfed and lodging can be controlled by cutting in late July. in addition, by using the bud cutting method, the tall Dahlia can be planted in a pot with a diameter of more than ten centimeters. the plant height is only small and the flowers are large and colorful. Chrysanthemums are dwarfed by horn buds.

Second, through plastic pruning, the main branches are removed to promote the germination of side branches when the plant is young, and then cut off too many side branches that do not grow well, in order to achieve plump plant type, low plant, and improve ornamental. Rose, a string of red, rhododendron, foliage flowers and other pruning mostly use this method to dwarf. Daffodils are dwarfed by needling and carving.

Third, controlled fertilization should timely apply phosphorus and potassium fertilizer to potted flowers, apply less nitrogen fertilizer, control plant vegetative growth and achieve dwarfing.

Fourth, the artificial bending stem artificially distorts the branches, which hinders the nutrient transport channel of the plant, slows down the growth rate of the plant, and achieves the low type of flower plant. Generally, it is widely used in the production of small bonsai.

Use of plant growth regulators

1. Spraying a string of red plants with paclobutrazol can make the internodes shorter, the leaf area smaller and the leaf color deeper, thus changing the phenomenon of tall and thin stems, sparse flowers and leaves and serious de-flowering of a string of red plants, and improve the ornamental value. In addition, goldfish grass, chrysanthemum and other flowers are also often used in dwarfing.

2. The treatment of a bunch of red and other plants with propranolol can reduce the plant height by 26%, shorten the stem nodes, increase the number of branches, and improve the ornamental ability.

3. The treatment of the plant with B9 can inhibit the vegetative growth of morning glory, dwarfing it by 61.5-67% in the vegetative growth period and 40.5% in the full flowering stage, so that the plant type is short, the branches and leaves are compact, and the flowering is concentrated. 4. Dwarftin can inhibit the vegetative growth of petunia flower, which can dwarf its plant type and improve its ornamental ability.

Radiation treatment of some flowers, but also through radiation treatment to change the growth status of plants, so as to achieve dwarfing, for example: the treatment of daffodil bulbs with Y rays can control the growth of daffodils and dwarf narcissus plants. When the canna was treated with 60 ℃, the height of canna could be reduced by 30-50 cm and the ornamental value could be increased.
