Culture methods and matters needing attention of Cymbidium
1. Substrate requirements for Cymbidium Culture
Cymbidium can be cultivated with fern root, peat, moss, bark, charcoal block, broken brick and so on.
two。 The methods of going up and changing pots for Cymbidium culture
As a rule, when the plant is too large, the pot should be changed or the ramet should be put on the pot to promote growth and flowering. Upper basin or change basin should be carried out after flowering or when the new buds are just sprouting in early spring. The method of changing the basin: pour the plant out of the old basin, cut off the rotten roots and yellow leaves, and remove the old matrix; put a layer of broken tiles or bricks at the bottom of the new urn to facilitate drainage and ventilation; put the plant in the basin, fill it with the new substrate, compact it with your hands and pour water through it.
3. Watering method of Cymbidium Culture
Cymbidium is a kind of flower that needs more water, especially in summer, it not only needs sufficient water, but also needs to spray water to the leaves to cool down and increase humidity. The inflated pseudobulb of Cymbidium has the function of water storage, so it has a certain degree of drought tolerance. But if it is not watered enough, the inflated pseudobulbs will shrink and affect normal growth. In addition, watering should be reduced during flowering, otherwise the flowers will appear brown spots.
4. Fertilization methods for the Culture of Cymbidium
In the vigorous growth period, rarefied fertilizer and water should be applied every 10 days or so, and little or no organic fertilizer should be applied in the seedling stage and low temperature season. Nitrogen, phosphorus and potassium compound fertilizer with a ratio of 7:6:19 can be used for foliar spraying. Cymbidium needs more fertilizer. If the nutrients are insufficient, the leaves will yellowed and fall off and the flowers will become smaller. therefore。 It is necessary to strengthen fertilization. Fertilization is applied once every 5-7 days in spring and summer, once every 10-15 days in autumn, and can be stopped in winter. During the growing period in spring and summer, the standard fertilizer diluted 1000 times of nitrogen, phosphorus and potassium should be applied, and more potash fertilizer should be used in autumn, which can be sprayed with 800-1000 times potassium dihydrogen phosphate.
5. Control of Diseases and insect pests in Cymbidium Culture
The main diseases of Cymbidium are leaf blight, anthracnose, soft rot and leaf spot, which can be controlled with 50% carbendan 500 times or 50% carbendazim 500 times, and soft rot and leaf spot can also be sprayed once a month with topiramate or chlorothalonil. The main pests are aphids, red spiders, shell insects and so on. 1000-fold solution of fenitrothion and omethoate EC can be used to control aphids, and 800-fold solution of triclofenac or dichlorvos can be used to control red spiders, once every 15 days.
6. Temperature requirements for Cymbidium Culture
Cymbidium prefers warm, cool, moist and semi-overcast environmental conditions. The suitable temperature for growth is 15-25 ℃. If the temperature is lower than 10 ℃ or higher than 35 ℃, it is better to enter dormancy, and the overwintering temperature is not lower than lO ℃. When the temperature difference between day and night is less than 10-15 ℃ in most varieties, flower bud differentiation can be carried out smoothly.
7. Matters needing attention in the Culture of Cymbidium
(1) compared with other orchids, Cymbidium prefers light, but can not be exposed to direct sunlight. Seedlings need 70% / 80% shade, 60% big seedlings, 40% / 50% shade in spring and autumn, 60% shade in summer, and more light after late autumn. to facilitate flower bud differentiation and bud blooming. The growth of Cymbidium needs high air humidity and sufficient moisture. The suitable air relative humidity for seedling growth is 80%, and the pH of water quality should be pH5.4~6; keeping the substrate moist in the peak growing season, often spraying water on plants and roots, and maintaining air humidity are beneficial to growth and development; there is a dormant period after flowering, and less watering is required.
(2) Cymbidium is the most fat-loving type of orchids. The flower bud differentiation period of Cymbidium is from August to September, and there must be obvious temperature difference in order to promote flower bud differentiation, that is, about 25 ℃ in daytime and 12-15 ℃ at night. If the night temperature exceeds 15 ℃ during flower bud germination, it will cause flower bud to wither. Good ventilation is a favorable condition affecting the growth and development of Cymbidium. For example, poor ventilation, especially in summer, is not conducive to the normal growth and development of Cymbidium, affecting the differentiation of flower buds, resulting in the phenomenon of only long leaves but no flowering.
This is the end of the breeding methods and matters needing attention of Cymbidium. Next, I would like to introduce the distribution range of Cymbidium.
Culture methods and matters needing attention of Cymbidium grandiflora
Cymbidium prefers warm, cool, moist and semi-overcast environmental conditions. The suitable temperature for growth is 15-25 ℃, which is lower than 10 ℃ or higher than dormancy. The flower bud differentiation of most varieties can be carried out smoothly when the temperature difference between day and night is less than 10-15 ℃. The following is a detailed arrangement of Cymbidium cultivation methods and matters needing attention, as well as maintenance methods throughout the year.

2. Cymbidium is the most fat-loving type of orchids. The flower bud differentiation period of Cymbidium is from August to September, and there must be obvious temperature difference in order to promote flower bud differentiation, that is, about 25 ℃ in daytime and 12-15 ℃ at night. If the night temperature exceeds 15 ℃ during flower bud germination, it will cause flower bud to wither. Good ventilation is a favorable condition affecting the growth and development of Cymbidium. For example, poor ventilation, especially in summer, is not conducive to the normal growth and development of Cymbidium, affecting the differentiation of flower buds, resulting in the phenomenon of only long leaves but no flowering.
3. The transport temperature of Cymbidium is more than 5 ℃. If the bracts and leaves turn yellow, the freezing injury may occur.
4. Imported Cymbidium standards: Cymbidium imported from Japan and South Korea generally requires a plant height of 60 to 80 centimeters, 15 to 20 flowers per arrow, 3 to 5 arrows per pot, and a flowering degree of 50 to 80 percent per arrow. the difference in the height of flowers and arrows between pots is not more than 5 cm.
5. Flowering maintenance of Cymbidium: the optimum temperature during flowering is 8 ℃ to 15 ℃, which can not be placed next to the high temperature and dry heating. The low temperature flowers with 2 ℃ to 3 ℃ for a long time will suffer frost injury, and the bud will turn yellow and cannot open. The ornamental period is 50 to 80 days.
Culture of Cymbidium in four seasons 1. Spring management
As the temperature begins to rise in spring, ventilation should be strengthened as much as possible to keep the flowering plants in a cooler environment. As the temperature changes greatly during the Spring Festival, do not rush to move it outdoors to protect and promote the growth of new buds, wait for sufficient light before moving to outdoor cultivation. Water should be watered once a day, while flowering plants can only keep the pot soil moist. Fertilize once every 10-15 days. Spring is a good time to change pots or ramet propagation after flowering, which should be implemented as soon as possible. In order to reduce nutrient consumption, the branches of the withered flowers should be cut off immediately, otherwise the growth of new buds will be affected.
2. Summer management
Summer is the early stage of flower bud differentiation, because high temperature is not conducive to flower bud differentiation, so attention should be paid to cooling to promote flower bud differentiation. The temperature below 28 ℃ in summer is beneficial to growth. As the summer sun is strong, 30% of the light should be blocked to protect the leaves from the scorching sun. Water twice a day, if dry at high temperature, spray to the leaf surface. Before July, liquid fertilizer was applied once in about 15 days. Adding solid compound fertilizer once a month can contribute to the growth of new buds, and spraying pesticides and fungicides once a month can effectively control diseases and insect pests.
3. Autumn management
The temperature difference begins to increase in autumn and should be moved into indoor cultivation from October to avoid slow plant growth due to low temperature at night. At this time, sufficient sunlight should be satisfied to increase the accumulation of nutrients. The weather is getting colder in autumn, and it is usually watered once every two days to make the substrate moist as far as possible to protect the newly developed flower buds. During the growth of flower buds, more phosphorus and potassium fertilizer should be applied to make the flower buds fat.
4. Winter management
This is the period when Cymbidium begins to bloom, so be careful that the temperature at night should not exceed 20 ℃, otherwise the buds will fall off. It can be fully exposed to sunlight in winter, making the plant sturdy. It can be watered every 3-4 days in winter, and the humidity is maintained at 60%-70%. Attention should be paid to preventing snails that eat flowers. Fertilization should be stopped during flowering.
Culture methods and matters needing attention of Cymbidium
Cymbidium is native to tropical plants in India, and was later introduced into southern China and bred after crossing with local orchids. This plant has bright colors, large flowers and good ornamental value. It can be cultivated in scenic spots or potted indoors. However, many people do not understand its breeding methods and do not know what to pay attention to in cultivating this kind of plant. Today, the editor will give you a specific introduction.
Culture method
1. Soil
In order to cultivate Cymbidium, the choice of soil is very important. It likes loose, breathable and well-drained soil. It can usually use rotten leaf soil to grow Cymbidium, and it can also use moss charcoal shavings and bark blocks to prepare basin soil. It can not use ordinary culture soil, because their ventilation and drainage are relatively poor, after planting will lead to the root rot of Cymbidium.
2. Moisture
Cultivation of Cymbidium can only be properly watered to make it grow normally. Cymbidium, a plant that likes high temperature and high humidity, should give sufficient water to its roots in spring, summer and autumn, and spray water to the leaves in time. However, after flowering in early spring, Cymbidium will enter a short dormant period, which is necessary to reduce the water supply and wait for the new buds to grow larger before they can be watered more.
3. Sunshine
Cymbidium is a sunny plant, it likes to grow in a sunny environment, but it can not accept strong light, it is best to put it in an environment with plenty of scattered light, but after entering the flowering period, Cymbidium should be placed in a place with weak light, so that its flowers can be more beautiful.
Matters needing attention
During the cultivation of Cymbidium, we must pay attention to the prevention of diseases and insect pests, leaf spot disease, gray mold and other diseases should be timely sprayed carbendazim, after the occurrence of insect pests should be caught in time, or spray drugs. In addition, when cultivating Cymbidium, we should also pay attention to pruning. Its pseudobulbs generally contain more than four leaf buds, so that their nutritional molecules must be removed completely.

Culture method of Daphne odorifera
First, the basin soil is of moderate size, contains an appropriate amount of humus, and the soil is relatively loose. After matching the soil, it is necessary to expose and sterilize in the hot sun. I remember to change the basin soil every two years, and the big pot needs to be replaced when the plant grows up. Second, the leaves of watered Daphne contain a lot of wax, so they are relatively smooth.
