Cultivation methods and matters needing attention of camellia.

Camellia, also known as camellia, is the national flower of Yunnan Province. As a traditional famous flower in China, many people like to raise it. People who love flowers, in particular, will keep several pots of camellia at home. However, how to make good use of camellia is inexperienced. The following are the cultivation methods and precautions of camellia. 1. Soil is the growth foundation of potted camellia, because the root system of camellia depends on the growth and development of soil, and the water and nutrients needed for camellia life activities are mainly absorbed from soil. Camellia likes mountain red loam with high humus and loose ventilation, and its pH value is between 5 and 6.5. Alkaline soil or cohesive soil cannot be used as the substrate for potted camellia. Soil preparation: 50% mountain soil, 40% sawdust or edible fungus residue, cake fertilizer powder or livestock manure and phosphate fertilizer powder 10%. The three materials are evenly mixed, properly watered, bagged and maintained for more than 20 days in summer and autumn and more than 30 days in spring and summer. This kind of soil is not only loose and breathable, but also can keep fertilizer and water, which is suitable for the growth and development of camellia. 2. Illumination Camellia needs proper illumination, but it is afraid of direct sunlight. In spring and late autumn, camellia should be moved to the balcony or sunny ground for full-day illumination to promote the growth and development of the plant, promote the differentiation of its flower buds and make its flower buds strong. When the sunshine is strongest in summer, the flowerpot should be moved to a well-ventilated environment, or moved to the north balcony or Nanyang terrace for cultivation. You can also cover plants with 75% sunshade net from 9: 00 am to 5: 00 pm to avoid direct sunlight, causing leaf trauma or plant withering. If possible, move the camellia to the sun shed to escape the heat safely. 3. Temperature is one of the important conditions for the growth of camellia. Camellia likes warmth, the optimum temperature is 18 to 25, and the relative humidity is 60% to 65%. For the growth of tea flowers, the spring shoots generally germinate in the middle and late March, start to germinate in April, form terminal buds in the middle and late May, stop growing, and gradually differentiate into leaf buds or flower buds. It takes 180 to 240 days from flower bud formation to flowering. Summer buds germinate in late July and stop growing in early September. Camellia is resistant to low temperature, but when the cold wave invades, the temperature drops below 0 or when it encounters dry northwest wind, it will freeze the shoots and the flower buds will wither due to freezing injury. Therefore, the flowerpot will be moved to the north and south of the back for maintenance to ensure its safety in winter. 4. The watered camellia leaves are many, with large leaf area and fast transpiration. Camellia likes humid climate and moist soil. Therefore, potted camellia must be hydrated, watered once a day during the spring and autumn growth period, and watered once in the morning and evening in summer, especially in dog days. If the ground is dry, water or spray water around the ground and flowerpots once or twice to maintain a certain air humidity, so that plants can flourish. At the same time, it should be noted that the soil of flowerpots will be alkalized over time because of too much watering, and most families water them with tap water. So when watering, you can add 0.5% to 1% ferrous sulfate water every month, or spray leaves with 5% to 8% vinegar. Camellia likes wet soil, but they are afraid of water in flowerpots. If there is water in the flowerpot on rainy days, it must be removed in time to prevent the roots from suffocating and rotting in the water. 5, fertilizer Camellia is a kind of fertilizer-loving flower, because the tree is strong, there are many leaves, and the flowering period is long, so it needs more fertilizer. In the process of fertilization, cooperate with changing pots and apply sufficient liquid fertilizer and long-acting fertilizer. According to the size of the flowerpot, add 3-80g of decomposed cake fertilizer powder or dried chicken and duck manure to each flowerpot, put it under the flowerpot and mix well with the subsoil. According to the plant growth period, increase the application amount of organic fertilizer. In addition to the coldest and hottest time in winter and summer, apply decomposed cake water once or twice a month. Fertilization method: scrape the soil around the basin for about 2 minutes, apply liquid fertilizer into the ditch and cover it with soil to avoid odor. You can also apply th.

6. Environment Camellia likes to grow in an environment with moderate air flow and likes the breeze. It likes the water vapor brought by the southeast wind, but it is afraid of the northwest wind and strong wind, which makes the water evaporate too fast, the supply and demand of camellia lose balance, and the leaves of camellia are easily damaged, resulting in the phenomenon of falling buds and flowers. Camellia should be kept in a cool, sunny, temperature and humidity environment in winter. In spring and autumn, the flowerpot should be moved to the balcony, so that it can be ventilated, transparent and shaken by the breeze. This not only contributes to the good growth of plants, but also contributes to the differentiation of flower buds, the growth and development of buds, and reduces the occurrence of pests and diseases. Through years of practice, it has been proved that moderate ventilation and light can prevent pests and diseases.
