Six measures for dwarfing flowers and preservation methods of edible fungi

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 as follows:

I. asexual reproduction

The asexual propagation methods such as grafting, cutting and striping can achieve the effect of dwarfing, shorten the flowering stage, reduce the plant height and compact 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 basin with a diameter of more than ten centimeters, the plant height is only enough and the flowers are large and colorful.

II. Shaping and pruning

Through plastic surgery, remove the main branches to promote the germination of lateral branches when the plant is young, and then cut off too many poorly growing lateral branches, 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 can be dwarfed by acupuncture and carving.

III. Controlled fertilization

Timely application of phosphorus and potassium fertilizer and less nitrogen fertilizer to potted flowers can control the vegetative growth of plants and achieve dwarfing.

IV. Artificial dried koji

Artificially twist the branches, block the nutrient transport channel of the plant, slow down the plant growth rate, and achieve the low plant type of flowers. 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 stems, 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.

two。 When a bunch of red and other plants were treated with propranolol, the plant height decreased by 26%, the stem nodes became shorter, the number of branches increased, and the ornamental ability was improved.

3. The plant treated with B9 can inhibit the vegetative growth of morning glory, making it dwarf 61.5-67% in vegetative growth period and 40.5% in full flowering stage, so that the plant type is short, the branches and leaves are compact, and the flowering is concentrated.

4. The plant type can be dwarfed and the ornamental ability can be improved by inhibiting the vegetative growth of petunia and other petunias.

VI. Radiation treatment

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