Six measures of dwarfing flowers
With the development of the flower industry, miniaturized, compact potted plants and bonsais are becoming more and more popular with people. Therefore, dwarfing technology of flowers is increasingly showing its vitality. The main techniques for dwarfing cultivation are the following six:
First, asexual reproduction
The dwarfing effect can be achieved by using vegetative propagation methods such as grafting, cuttings, and layering, shortening the flowering stage, reducing plant height, and compacting the plant type. Grafting can be achieved by selecting dwarfing varieties for dwarfing. The cutting height can be determined by considering the cutting time. For example, chrysanthemums can reach dwarfing and control lodging in late July. In addition, the planting of tall dahlias can be planted in pots with a diameter of more than ten centimeters with the budding method. The plant height is only limited by the size and color of the flowers.
Second, pruning
Through shaping, remove the main branch of the plant to promote its germination side branch, and then cut too many poorly developed side branches in order to achieve full plant type, low plant height, and improve ornamental. Roses, rosettes, rhododendrons, and foliage are used for dwarfing. Narcissus dwarfs the growing point by acupuncture and engraving.
Third, control fertilization
The timely application of phosphorus and potash fertilizer to potted plants, less nitrogen fertilizer, and control of vegetative growth of plants to achieve dwarfing.
Fourth, artificial Qugan
Artificially distort the branches, so that the plant nutrient transport channels are blocked, slowing down the growth rate of the plants, and reaching the low level of the flower plant type. Generally used in the production of small bonsai more.
Fifth, the use of plant growth regulators
1. Spraying a series of red plants with paclobutrazol can shorten the internodes, reduce the leaf area, and deepen the color of the leaves, thus changing the phenomenon of high stem thinness, sparse flowering and severe flowering of a series of red plants, and increasing ornamental value. . In addition, snapdragon, chrysanthemum, and other dwarf flowers are often used.
2. Treating a bunch of red plants with D-glycidamine can reduce plant height by 26%, and the stem segments become shorter, the number of branches increases, and the ornamental quality increases.
3. The treatment of plants with B9 could inhibit the vegetative growth of morning glory, making it 61.5~67% dwarf during vegetative growth and 40.5% dwarf at full flowering stage, thus making the plant type dwarf, the branches and leaves compact and flowering concentrated.
4. The use of chlormethasine to inhibit the vegetative growth of petunia flowers can make the plant type dwarf and enhance ornamental quality.
Six, radiation treatment
Some flowers can also be used to alter the growth of plants through radiation treatment to achieve dwarfing. For example, treating narcissus bulbs with gamma rays can control daffodil growth and dwarf narcissus plants. Treating the canna with 60°C can reduce the height of the canna 30 to 50 cm and increase the ornamental value.
