The multi-headed chrysanthemum is a flower that grows in more than two flowers per chrysanthemum. Because it is multi-colored and colorful, it is a common material for arranging flower beds or arranging potted flowers on the National Day. In the autumn season, its arrogant Lingshuang posture is elegant, colorful, and the protagonist in the singer's show is deeply loved by the masses. Now I will talk about a few management aspects that need to be mastered in order to nurture a large number of chrysanthemums.
1, species selection
Suitable varieties of chrysanthemums are widely used. Generally, large chrysanthemum varieties can be cultivated. In particular, flower varieties with large flowers, abundant flowers, tall and straight branches, even leaf sections, and robust plants have better results. Several flowers can be evenly and neatly arranged. Shaped one effect.
2, timely cutting
The time for cutting and breeding depends on the number of flowers to be cultivated in each pot, and it is recommended to raise dozens of flowers. It is best to pick and shoot buds at the end of the first year of the year. If you only raise up to ten or less, you can cut in the early April of that year. The cutting head should be selected as the strong head of the strong branch. The length is about 8 cm. Only the parietal lobe is left, and after filling, it is filled with white plastic film. shade. Pay attention to water spray during the period to keep the soil moist, and take root after 20 days of routine management. Premature cuttings are prone to premature hair and difficult to control height.
3, pull the heart
Once the seedlings are alive, timely bring the pots on the mud, and then put them under the arbor for conservation. After serving the pots for several days, the young seedlings should be placed in a space where there is plenty of sunshine and air circulation, so that the pots and soils are often brought dry to prevent the growth of the chrysanthemum seedlings. When the height of the chrysanthemum is about 15 centimeters, it starts picking the heart. At this time, only the bottom 2-3 leaves are picked up to make it sprout again. The last topping must be completed 10 days after the beginning of autumn. If you need to flower dozens of flowers, you should repeat the above-mentioned method.
4, change the flower pot
The seedlings that survived were transplanted in small 4-inch pots. At this time, the seedlings were not strict with the soil quality. It was sufficient to use some adobe soil with horse manure, and then put them on a sunny and water-free site to maintain the water. Weeding and weeding in time to promote root growth. When the weather turns cold after the beginning of autumn, change the flowerpot and plant it in a pot of 8 inches or so. The pelvic floor is best placed with 30 grams of horseshoe for long-term supply of nutrients. Then, add 5 parts of humus, 2 parts of garden soil and 3 parts of horse manure that were previously tanned. The Xia Ding seedlings in the new basin were only filled to 1â„2 of the basin depth. This is the time of the rainy season. If the filling is overfilled, the new roots have not yet grown. Poor, not conducive to the growth of the roots. With the growth of the new plant, it has been filled in 2 times. Due to the large depth of soil, the main trunk of the original plant was buried in the potted soil, reducing the branch height of the chrysanthemum plant. When changing the soil, remove some of the old soil properly, cut some old roots, and injure the roots. It can not only inhibit the growth of the chrysanthemum plant, but also promote new roots and make it grow robust in the later period.
5, fertilizer and water management
In the maintenance stage before the beginning of autumn, it is not necessary to apply large fertilizers. Apply 3-5 times of abattoir liquid and green manure water before changing basins. If the fertilization is too early, it will easily lead to premature and premature aging. It is difficult to control the height, and it will cause poor growth later and affect flowering. After the beginning of autumn, topdressing 1 liquid fertilizer, such as soaked fermented soy sauce, bean cake, horseshoe and soy liquid fertilizer, etc.; or topdressing about 30% of decomposing human excreta, while spraying fertilizer, also use foliar spray, ie 0.3 Percentage of urea and 0.2% of KH2PO4 were sprayed on the foliage once a week until budding. However, care should be taken to prevent excess fertilizer, and the first and second days after fertilization should be backwater, that is, chasing the fertilizer once and pouring it twice. The watering of the chrysanthemum should be based on the sunny days and more pouring, the cloudy days less pouring, the seedlings mostly pouring, the principle of the seedlings less pouring and flexible. Watering is usually done in the morning, and watering at night can easily make the plants pull up. To prevent water accumulation in the basin on a continuous cloudy day, it is best to use cover measures to prevent the chrysanthemum from being adjusted by the rain.
6, dwarfing treatment
It is critical to control the height of the chrysanthemum in the process of growing the chrysanthemum. Generally, a 1% solution of chlormethorine (or B9) is sprayed once a week. Spraying begins one month to one and a half months before budding until bud emergence. The spraying time is best selected in the evening, when the pressure is low, the absorption is good, and the spraying is even. If it happens after treatment, it will rain in just 24 hours and immediately after sunny day it will be sprayed once. Spraying Chlorophyll can not only make the plants dwarf, but also increase the leaf color.
7, shaping and selection
The chrysanthemum has a balanced plant type, normal leaf color, uniform flower size, and uniform flowering period. To achieve this standard, it is necessary to adjust the growth of each branch as early as possible. The water should be drained before the yak and the plants should be smashed so as not to break, and then the orientation of each twig is adjusted and a thin green bamboo lacquer sash is tied. When tying, pay attention to the consistency of the branches. When placed, the weak branches should face south, and the strong branches should face the north, so as to balance the growth of the branches, so that all sides have ornamental value. When the flower buds have bean size, they should be stripped immediately. Individuals with buds that are too early or too large can be allocated buds and left buds, and small and deformed disability buds should be removed early.
To produce large quantities of potted chrysanthemums, to be diligent in management, to be good at thinking, and to find problems as early as possible. Diseases and insect pests occur frequently in most flower growth cycles. It is necessary to strengthen ventilation and light transmission, and to observe them closely so that the occurrence and spread of pests and diseases can be curtailed as soon as possible. A cultivator, a harvest, and carefully cultivated gerbera will be the first in the chrysanthemum exhibition with its plant type, flower color and green leaves.
