Culture methods of camellias and pest control of camellias

Camellia plant shape is very beautiful, not only so colorful, colorful, loved by the world horticulture community. Then, let's take a look at the planting methods of camellias together with the editor, as well as the relevant introduction to the prevention and control of diseases and insect pests. I hope we can help you all. Let's take a look!

The cultivation method of camellias first, planted in the north of the Yangtze River, camellias have been planted in spring, in the south of the Yangtze River, autumn planting is better. To adopt the way of land planting, we should choose the land with good drainage and strong water retention, and the sandy loam rich in humus. If it is potted, it is selected as follows: rotten leaf soil, sandy soil, stable fertilizer soil, or 4 parts of rotten leaf soil, 5 parts of peat soil and 1 part of coarse sand. The pH is between 5 and 6.5. The planting land should choose a place where there is no stagnant water or can not be exposed to the hot sun. Potted camellias are placed in a ventilated and transparent place in winter and in a shady shed or other shady place in summer. The camellias move randomly, which is disadvantageous to the growth of camellias. Second, light and temperature Camellia is a kind of plant with long sunshine. Flower buds can only be formed in an environment that lasts 12 hours a day. The optimum growth temperature is 18: 25 ℃, and the optimum flowering temperature is 10: 20 ℃. If the temperature is higher than 35 ℃, the leaves will be burned. Camellias are not cold-resistant and should be admitted in winter. The temperature should be kept at 3: 5 ℃. It can also endure a low temperature of-10 ℃ for a short time, but not more than 16 ℃ for a long time, otherwise it will promote germination and cause fallen leaves. During the growing period, you should be placed in a semi-overcast environment and should not accept excessive direct sunlight. Especially in summer and autumn, shade should be carried out, or under the trees in a sparse shade. Third, the requirements of watering and fertilization for fertilizer and water, camellia are higher, alkaline soil and neutral soil are disadvantageous to the growth of camellia. In the north, special attention should be paid to the fact that alkaline water should be acidified before watering flowers. The specific method is to store tap water for 2 days to volatilize the chlorine in the water, and then add an appropriate amount of ferrous sulfate (about 0.5% of the water). The amount of water should not be too large, too much water is easy to cause rotten roots. The basin soil can not be dry, and if there is a lack of water, it is easy to make the roots shrink due to the loss of water, so as to keep the basin soil and the surrounding environment moist. Don't spray water during flowering. It is better to apply fertilizer with thin alum fertilizer and water, and avoid applying thick fertilizer. Generally, after sprouting in spring, thin fertilizer and water is applied every 17 days, phosphorus and potassium fertilizer is applied in summer, fertilizer can be stopped for about one month in early autumn, alum fertilizer is applied again before flowering, and available phosphorus and potassium fertilizer is applied when flowering, so that the flower is big and colorful and the florescence is long. Fourth, shaping and pruning to plant camellia mainly cut off dry and withered branches, diseased and weak branches, cross branches and over-dense branches, which obviously affect the tree-shaped branches and remove excess buds. In addition to the above work, potted camellias should also be pruned according to personal preferences, but should not be re-cut, because their growth potential is not strong. Fifth, flowering control camellias are not cold-tolerant, generally use the selection of varieties, temperature control, hormone treatment and other methods to control flowering. If you want to make camellias bloom on National Day holiday, you can use a brush to dip 0.1% of gibberellin in mid-July or early August and apply them to the buds every 3 days. If it is estimated that the "National Day" flowering is not safe, it can increase the number of buds, increase fertilizer and water, promote the rapid growth of flower buds, and make the "National Day" see flowers.

6. Winter management of potted camellias (1) when the temperature drops below 0 degrees Celsius, move the potted camellias to a sunny place outside, or put them in a plastic shed sealed on three sides and sunny on one side. It can also be put indoors, but the place is required to be well lit and well ventilated. In case of severe cold and frost weather, you should pay attention to keeping warm, and it is best to move the outdoor camellias indoors before the sudden cooling. If it is placed outdoors, it should be covered with plastic film, newspaper or cloth at night. (2) Water and fertilizer management. Camellias like a warm and humid environment and are afraid of stagnant water. Spray the leaf surface with water whose water temperature is similar to room temperature every 3-5 days in winter to increase humidity and clean leaf dust. During the flowering period, it is appropriate for the basin soil to be dry and wet, and the suitable time for watering is noon on a sunny day. Winter is the bud expansion period of camellia, 0.1% to 0.3% potassium dihydrogen phosphate solution should be sprayed once a month combined with foliar water spraying, or thin liquid fertilizer dominated by phosphorus and potassium should be applied to the root (fertilizer-water ratio is 1:4) once a month. (3) when other indoor overwintering potted flowers bloom (early flowering varieties begin to bloom at the end of November, general varieties bloom from February to April), do not put them in places where the light is too strong or the temperature is too high, otherwise the flowers will die early. Plucking too many buds can make the flowers large and colorful, and prolong the flowering period. Do not spray water on the flowers when watering, otherwise it will cause the flowers to rot and shorten the flowering period. After the flowers fade, pick the residual flowers in time. The main diseases of camellias include ring streak, shoot blight, anthracnose, leaf spot, bituminous coal and so on. The main control agents are carbendazim 500 times, chlorothalonil 800 times, carbendazim 800 times, and carbendazim 800 times regularly. Attention should be paid to the prevention and control of gray mold and flower blight before flowering. The main pests of camellias are red spiders, aphids, scale insects, leaf rollers and bridge worms. The main control agents are cypermethrin 15ml + isocarbophos 20mL or monocrotophos 25mL mixed with 30 jin water spray. Summary: the above is the introduction of the culture methods of camellias, as well as the prevention and control of diseases and insect pests. Different flowers have different meanings and different points in breeding, which can enable us to better maintain flowers. The editor's information is not comprehensive enough, so please forgive me.

The Culture method of Camellia the language of Camellia

Camellia ranks seventh among the "top ten famous flowers" and is one of the more valuable flowers and trees in the world. Today, I'm going to tell you about the culture method and the flower language of camellia.

The flower words of camellias:

Nobility, modesty, ideal love, prudence, supernatural charm

Camellia (white): pure and innocent

Camellia (red): natural beauty

The flower language of camellia is: ideal love, humility.

The culture method of camellia:

1. Place of placement: Camellia prefer semi-shade and avoid the scorching sun, so it is suitable to be placed in a warm, moist, ventilated and transparent place. Breed camellia in spring to have sufficient light, summer should pay attention to shade, avoid direct sunlight, if the camellia on the balcony, often accidentally it will be sunburned to death. Camellia in the process of storage and transportation, it is necessary to prevent high temperature and air drying, otherwise buds and flowers are easy to fall off, affecting the quality.

2. Temperature: Camellia likes warm climate, the suitable growth temperature is between 18 and 25 ℃, the initial flowering temperature is 2 ℃, it is slightly cold-tolerant, the general variety can withstand the low temperature of-10 ℃ and summer heat, but more than 36 ℃ will inhibit its growth. The cultivation of camellia requires a certain temperature difference, and the best environmental humidity is above 60%. It can generally survive the winter naturally in the south of the Huaihe River, while the varieties of Camellia are slightly less resistant to cold.

3. Watering: Camellia bonsai culture should keep the soil moist, but not stagnant water, so as not to affect the growth when dry and wet. In general, more water can be properly watered in spring, which is conducive to sprouting and sprouting; in summer, it is best to spray foliar water, so that the leaves are drenched thoroughly, not hot water should be watered, and the high temperature before and after noon should be avoided; proper amount of water should be watered in autumn; it is appropriate to water around noon in winter and spray water every two or three days.

4. Fertilization: Camellia likes fertilizer, so pay attention to put a layer of base fertilizer in the basin soil, mainly phosphorus and potassium fertilizer, and the best fertilization is the mixture of rotten bone powder, hair, chicken feathers, rice chaff ash, poultry dung and calcium superphosphate. Usually, it is not suitable to apply too much fertilizer, generally apply 2 or 3 times of thin fertilizer from April to May after flowering, and apply a slightly thicker water and fertilizer in autumn and November. Camellia fertilizer pay attention to the proportion of phosphate fertilizer should be slightly larger, in order to promote the flowers colorful.

5. Pruning: Camellia grows slowly and should not be overpruned. Generally, long branches, disease and insect branches and weak branches can be cut off. If there are too many buds on each branch, you can sparse the flowers, leaving only 1 or 2 buds and keeping a certain distance, and the rest should be picked as soon as possible so as not to consume too much nutrients. In addition, it is necessary to pick the withered flowers in time, which can also reduce the consumption of nutrients, so as to facilitate the robust growth of camellia and form new flower buds.

6. Turning the pot: it is best to turn the pot once every two years, and the new pot must be one size larger than the old pot, which is beneficial to the root system development of camellia. The best time for turning the pot of camellia is in April in spring, of course, it can also be carried out in autumn. When turning the basin, combined with soil replacement, properly remove part of the hardened old soil, replace it with fertile, loose, breathable new culture soil, and first place a layer of base fertilizer.

7. pest control: the common diseases of camellia are black mold and anthracnose, which can be controlled by spraying 0.5 degree Bordeaux solution. Usually, management and careful maintenance should be strengthened to enhance plant disease resistance and reduce the chance of infection. If the cultivation of camellia is not well ventilated, it is very easy to suffer from pests such as red spiders, tea tip moths and shell insects. This kind of pest control method is to cut off the insect tips, which is generally carried out from April to June. It can also be sprayed with 1000 times omethoate EC to control or wash clean.
