How to cultivate chrysanthemum

In the process of chrysanthemum cultivation, the main technical links are: potting and soil preparation, maternal seeding, breeding, upper basin colonization, water and fertilizer management, and trimming buds to remove buds.
Basin soil preparation Potted chrysanthemum soil requires loose soil, rich humus. Chrysanthemum is the most feared to plant in the original place or use old potted soil planted with chrysanthemum, because continuous cropping will lead to deterioration of the physical and chemical properties of the soil and adversely affect the growth of chrysanthemum. Therefore, prepare new cultivation soils every year.
In order to retain and develop different varieties of chrysanthemums, the female parent should be registered one by one during the flowering period and numbered. In mid-November, we chose to plant leeward plants in Yangyang (more than 3cm deeper than the original soil ball), then wet the rooting water, apply liquid fertilizer and cover sugar ash 3 days to 4 days after planting, cut off the ground Flowering branches and old stems. If the winter drought, pay attention to timely watering. In the following year, sugar ash can be plucked in March, and cultivating and weeding will be carried out. Fertilization will be applied 2 to 3 times to promote sprouting. At the beginning of April, the head was removed and usually 3 strains were kept per plexus.
Chrysanthemum breeding methods include cuttings, ramets, grafting, sowing, etc., generally based on cuttings. Chrysanthemum cuttings can be started in early April after clear and bright, and can be divided into batches and can be continued until early July. Generally, short-cultivation varieties are inserted early and high-grade varieties are inserted late. The cuttings should be selected from the sturdy shoots of a vigorous female parent, cut at the top about 3 cm, remove the lower leaves, and cut the base with a sharp knife. The spacing is 3 cm 4 cm, first use a bamboo stick to insert a small hole, then insert the cuttings into the soil 1 cm, with the use of fingers with compaction. Immediately after the water spray, do a good job shading facilities. Before watering, water should be sprayed. After rooting, watering can be appropriately reduced. After cuttings, rooting can be carried out for about 3 weeks to 4 weeks. After rooting, the pots can be planted separately.
Upper basin colonization should be done on sunny or cloudy days. Cutting seedlings are picked up once during transplantation. The pelvic floor mats are coarse-grained soils and are filled with culture soil. After planting, diligently eliminate weeds and keep the surface loose.
Water and Fertilizer Management When chrysanthemums are put on pots, they should be watered less, and when they are alive, the amount of water will be determined depending on the degree of soil moisture and weather conditions. Appropriate amount of fertilizer should be paid attention. Generally, thin and thin human fecal liquid fertilizer is applied once every half-month, and fertilization is not suitable when it is too hot or too dry. At the beginning of September, the chrysanthemums were changed once for the buds at the time of budding, so as to suppress the growth and promote the development of buds. When changing the basin, remove some of the soil and add some fertilizer. After that, gradually increase the concentration of fertilizer. Apply fertilizer once every 3 days to 5 days to promote rapid expansion of buds. However, chrysanthemum does not need to be top-dressed during the bud period, but it is also necessary to avoid applying phosphate fertilizer. Different varieties require different amounts of fertilizer. For example, the amount of fertilizer required for rosettes and lotus varieties is relatively large, while the amount of fertilizers required for single-leaflet varieties is less. Do not infect the leaves when fertilizing to prevent the leaves from coking.
The main purpose of topping, wiping buds, and removing buds and toppings is to achieve a predetermined number of flowering heads, and at the same time prevent the plants from growing too high. The general specimen of Ju topping heart 3 times - 4 times, Da Liju picking up 5 times - 6 times, cliff chrysanthemum to constantly picking. Plants have a higher number of pickings, and the number of slower pickings can be reduced. The picking should be timely, generally in the five leaves when the top three leaves removed, picking up the stem after the lignification, picking the heart of the bifurcation is easy to break lodging. After the beginning of autumn, stop picking up the hearts and sprout new sprouts between the new branches and leaves. These shoots must be erased at any time. Under normal circumstances, flower buds appear one after another from late September to early October, and budding and conservation can be carried out according to the requirements of cultivation.
