Planting African chrysanthemum should be carried out every spring or autumn, and the climate is appropriate, which is more conducive to seed germination. The planting soil is used to ensure breathability and loose. Seeds should choose healthy and full of pests and insect pests. Just sprinkle the seeds directly on it after handling it. After sprinkle, cover the thin soil, watering and moisturizing, and the seedlings can be growing soon. During the seedling period, we must strengthen management, and move to the flower pot when you wait for three or four true leaves. . Planting time The planting African chrysanthemum should be selected between from March to May or autumn from September to November from September to November each year. The climate is relatively suitable, which is conducive to seed germination. And the climate temperature of these two time periods is also beneficial to the germination of the seedlings, and the seedlings can grow better. . Preparation of potting soil If of African chrysanthemum sowing should be prepared first, use sandy soil, vermiculite, and peat soil to mix it. Mengbuilding is beneficial. Note that it is only available for disinfection. The flower pots can choose a mud pottery pot with good breathability. The size is determined according to the number of sowing. . Select seeds The seeds should be healthy and full of seeds when sowing. This germination rate is higher. Note that the seeds of pests and insect pests must be picked out, which will reduce the bud rate. . Seeding method In the pot soil is ready, you can sprinkle the seeds on it. After the top is sprinkled, it should be covered with a layer of thin soil, then poured the water once, so that the soil is wet, and timely in time Cover the plastic membrane to keep it and moisturize. 5. After the seeds, the maintenance treatment should be kept after the planting of African chrysanthemums. The temperature is best to keep the temperature between 20-30 degrees, so that it will only germinate in about a week. During the management period, the plastic film is opened every day to make it breathe. After the seeds are sprouting, given astigmatism, and more astigmatism will be exposed to the growth of the seedlings. When you wait for three or four true leaves, you can transplant it into the flower pot.
The production of African chrysanthemums can be produced for 2 to 3 years after planting, and it can be updated after 3 to 4 years. 1. Preparation of planting beds The African chrysanthemum root system is developed. Planting beds require at least 25 cm deep soil layer. The soil is loose, fertile, organic, and organic sandy loam soil. Earth, but it is better to be slightly acidic. Before planting, sufficient base fertilizer should be applied. The general standard is 15-20 meters per cubic meter of rotten agricultural fertilizer per 667 square meters, 50 kg of nitrogen, phosphorus, potassium compound fertilizer, and 50 kg of overlapping calcium phosphate. Flowing and turning over, it is planted with a width of 60 cm, a trench width of 30 cm, and a height of 30 cm. 2. Planting Thenan chrysanthemum cutting seedlings are mostly cultivated from professional seedlings. Essence The plant double -row is planted on the 畦. The plant line is 30 cm*40 cm. African chrysanthemum planting is based on the principle of shallow planting. Pay attention to exposing the root neck to the soil surface, otherwise it will easily cause rotten neck rot. Irrigation in the ditch after planting. 3. Management after planting (1) Temperature. The most suitable temperature for plant growth is 20-25 ° C. The temperature of the soil should be slightly lower, and the root is maintained in a state of 16 to 19 ° C, which is most conducive to the growth and development of the roots. If it can be maintained above 12-15 ° C in winter, and not exceeding 26 ° C in summer, it can bloom all year round. (2) light. The African chrysanthemums have sufficient sunshine, but they are not strong in summer. Therefore, there should be strong light in winter. In summer, pay attention to proper shading, and strengthen ventilation to reduce temperature and prevent dormancy from high temperatures. (3) Irrigation. The seedlings should be controlled to promote root development. The water supply should be sufficient during growth. But pay attention not to make the center of the leaves dip the water, otherwise it will easily cause flower bud to rot. (4) topdressing. The African chrysanthemum is the flower of the fertilizer, especially the variety of flowers is large, and the severity is high. The amount of fertilizer is large. The amount of nitrogen, phosphorus, and potassium requires 15: 8: 25. Pay special attention to the supplement of potassium fertilizer when topdressing. Potassium nitrate 0.4 kg, ammonium nitrate 0.2 kg or ammonium phosphate per 100 square meters of planting area per 100 square meters. Follow the spring and autumn every 5 to 6 days, and once every 10 days in winter and summer. At the peak of spring and autumn, 0.3%to 0.5%of potassium dihydrogen phosphate can be used for fertilization per week per week. If high temperature or low temperature causes a half -dormant state of the plant, fertilization should be stopped. (5) peeling and sparse buds. If African chrysanthemums In the process of growth, in order to improve the transparency of plant groups, the growth and flowering of balancing leaves, leaf peeling is needed. If the leaves grow too much, the number of flowers will be reduced, and the phenomenon of short stalks and small flowers will occur. Pay attention when peeling the leaves: usually leaves 3 to 4 branches of each plant for more than a year, and 3 to 4 functional leaves are left on each branch. Keep each branches and leaves when peeling. When peeling the leaves, first peel the diseased leaves, yellow leaves, and old leaves that have been cut off. If the small leaves in the middle of the plant are too dense, it is necessary to remove it appropriately to expose the flower buds to control nutrition growth and promote the development of flower buds. This is to improve the quality of flowers. In the early flowering period of the seedling growth stage, all flower buds should be removed before the plant has 5 functional leaves to ensure the growth and development of the plant. In addition, when a plant has more than 3 flower buds at the same time, it should also be properly sparse to avoid insufficient nutrients and affect the quality of cut flowers. (6) Flower picking. The most suitable time for cutting flower branches to be harvested when the pollen of the outermost wheel flower starts to spread. The plants with cut flowers should maintain the most vigorous growth potential. Do not cut the flower branches when the plant is withered or semi -closed at night, and the quality of the flower cutting quality greatly affects the bottle insertion of the cut flower. (7) After the collection. The chrysanthemum plate of Africa is large, long flowers, improper treatment after collection, and tongue -shaped petals are easily damaged. To this end, prepare for the hard cardboard of the flower branch. The cardboard is about 60 cm in length, about 40 cm wide, and 5 rows of round hole eyes on the top, 10 per line, a total of 50 holes, and the diameter of the hole is about 2 cm. After the cut flower branches are short and shorter. Each of the stems is inserted into one hole every 50 stems, so that the flower plate is fixed on the eye of the hole on the cardboard, and the flower stems are hanging vertically under the cardboard. After a plate is filled (50), the cardboard was lifted flat to the sink immersed in the fresh -keeping solution, immersed the base of the flower stem into the fresh -keeping solution, and was put on the market after freshness. Che 100 flowers in each box, and 2 cardboard pairs are placed in the box, the flower plate faces up, and the flower stems under the cardboard are tilted in the middle of the box neatly, and then covered with the lid.
