How to raise blue chrysanthemum

1. Temperature

The suitable growth temperature of blue chrysanthemum is a little different from that of other plants. The most suitable temperature for the growth of blue chrysanthemum is between 20 and 25 ℃. Too high or too low temperature will directly reduce the germination rate of seeds, so we should control its growth temperature when raising blue chrysanthemum.

2. Watering

When we sow blue-eye chrysanthemum seeds for daily maintenance, we must control the soil moisture, which is very important to the growth of blue-eye chrysanthemum. When we water the blue chrysanthemum, the hydraulic power should not be too large, the hydraulic power with great impact will damage the soil surface of the blue chrysanthemum, which will also affect the root system of the blue chrysanthemum.

3. Lighting

I believe flower friends all know that blue chrysanthemum is a kind of plant that avoids the heat. So how to raise blue-eye chrysanthemums in summer? It is too hot in summer, so we must protect it from shade in summer. If it is in other seasons, you can leave it outside to receive light to prevent the seedlings from overgrowing.

4. Fertilization

I believe that flower friends who have raised blue-eye chrysanthemum know that blue-eye chrysanthemum blossoms for a long time, so they will think that it needs sufficient nutrients to support it. In fact, we only need to apply a thin fertilizer before the flowering stage to allow the blue chrysanthemum to grow healthily during the flowering period, and to apply fertilizer once to resist the severe cold in the too cold winter.

The above is to introduce the problem of how to raise blue chrysanthemum, let's take a look at the pest control of blue chrysanthemum!

The main points of how to raise blue-eye chrysanthemum

Blue-eye chrysanthemum is a good ornamental flower, the cultivation of blue-eye chrysanthemum needs certain skills, how to raise blue-eye chrysanthemum? Next, let's take a look at the key points of blue chrysanthemum culture.

Introduction of Blue Mu Ju

Blue eye chrysanthemum alias African daisy, big flower blue eye chrysanthemum. Originally from South Africa, it is not resistant to cold. Avoid hot, suitable temperature 18 ℃ ~ 26 ℃, prefer sunny environment, suitable for soil with good drainage. Blue chrysanthemum plants are highly 20--60cm, basal leaves clustered, cauline leaves alternate, usually pinnatifid. Capitate inflorescences solitary, involucre tomentose, ligulate flowers white, abaxially lavender, discoid blue-purple. Achenes furrowed, villous. Blue chrysanthemum is a semi-shrub or perennial perennial herb with a height of 20cm and 60cm. Basal leaves clustered, cauline leaves alternate, pinnatifid. Blue chrysanthemum terminal head, the central blue-purple tubular flowers, tongue petal flowers, flowers are white, purple, light, orange and so on. Blue mu chrysanthemum is an annual herb with a height of 50 to 80 box meters, its stem is smooth and the upper part of the branch is pinnately parted into a linear shape. Capitate inflorescence terminal, its slender peduncle, ligulate flowers in a single whorl, middle and lower reddish brown, florescence for summer and autumn.

Key points of Culture of Chrysanthemum morifolium

1. Temperature

Given the appropriate temperature according to the requirements of specific varieties, the germination temperature of most seeds is between 20 and 25 ℃. Too high and too low temperature will directly affect the germination rate of seeds.

two。 Humidity

The management of moisture after sowing is very important. In winter, when the soil temperature is low at night, there is little water loss, so there is no need to replenish water or less water at the seedling stage; if the soil temperature is high, spray water should be sprayed according to the actual needs at the seedling stage. When raising seedlings in summer, water evaporates very quickly, and water must be replenished at any time according to the actual situation. If the seed is very fine, in order to avoid the erosion of water, the method of soaking basin can be used to replenish water.

3. Light

Except for some varieties such as cyclamen that need darkness during germination, most seeds are conducive to germination under light conditions. Seeds must be exposed to light after germination, otherwise the seedlings will grow too much.

4. Remove the cover

After the seeds germinate, the mulch should be uncovered in time. 60% of 70% of the seeds should remove the membrane after the cotyledons are unfolded to prevent the seedlings from overgrowing. At the same time, the humidity of the substrate should be maintained so that the cotyledons of some ungerminated seeds protrude successfully from the seed shell.

5. Transplant

When the seedlings grow to be suitable for transplanting, they should be planted or planted in time, otherwise it is easy to cause excessive growth of seedlings and production delay. The time of transplanting all kinds of seedlings is different, which should be decided according to the actual situation.

Originally from South Africa, it is not resistant to cold. Avoid hot, suitable temperature 18 ℃ ~ 26 ℃, like the sunny environment, should be well drained soil. Blue chrysanthemum plants are highly 20--60cm, basal leaves clustered, cauline leaves alternate, usually pinnatifid. Capitate inflorescences solitary, involucre tomentose, ligulate flowers white, abaxially lavender, discoid blue-purple. Achenes furrowed, villous. Morphological characteristics of blue chrysanthemum Chrysanthemum is a semi-shrub or perennial root herb with a height of 20 cm to 60 cm. Basal leaves clustered, cauline leaves alternate, pinnatifid. Blue chrysanthemum terminal head, the central blue-purple tubular flowers, tongue petal flowers, flowers are white, purple, light, orange and so on. Blue mu chrysanthemum is an annual herb with a height of 50 to 80 box meters, its stem is smooth and the upper part of the branch is pinnately parted into a linear shape. Capitate inflorescence terminal, its slender peduncle, ligulate flowers in a single whorl, middle and lower reddish brown, florescence for summer and autumn. The ecological habits of blue-eye chrysanthemum native to South Africa, blue-eye chrysanthemum is not resistant to cold. Avoid the heat, like to the positive environment. Soil with good drainage should be recommended. Blue chrysanthemum plants are highly 40--60cm, basal leaves clustered, cauline leaves alternate, usually pinnatifid. Capitate inflorescences solitary, about 7.Scm in diameter, total pedicel long 15--30cm, involucre tomentose, ligulate flowers white, abaxially lavender, discoid blue-purple. Blue-eye chrysanthemum achenes are furrowed and villous. Blue chrysanthemum likes sufficient sunlight, cool climatic conditions, strong cold tolerance, and no special requirements for planting soil. You can sow seeds in spring and autumn. The northern land is sown in March and April, and can blossom in May and June, and autumn sowing is usually in late September. Before the beginning of winter, you can overwinter with a little cover, mainly by sowing and breeding. The stems and leaves of snake chrysanthemum are bright and slender, the florets are light and elegant, and they are very wild, and because of their strong self-sowing ability, the flowers bloom continuously from spring to autumn, so they are suitable for planting in the family garden. Cultivation techniques of blue chrysanthemum sowing preparation 1. Raising seedlings blue chrysanthemum pot seedlings are recommended to use hole pots or seedling pots to raise seedlings, do not sow directly in the ground. Directly sowing in the ground, the soil spreads more diseases and insect pests, the ground temperature is lower, and the moisture and humidity are not easy to control, which affect the germination rate. It is also easy to calculate the germination rate by raising seedlings in hole pot. 2. The seedling substrate of blue chrysanthemum requires loose soil, good air permeability, water and fertilizer conservation, cleanliness and no disease, and good fertility. The commonly used substrates are peat soil, coconut bran, perlite and vermiculite. For example, peat 85% + perlite 10% + vermiculite 5%. Peat should not be too fine, perlite particles have a diameter of 3mi 4mm and vermiculite particles have a diameter of 3mi 5mm. Some fertilizers can be added to the matrix. Most seeds germinate well on the substrate with pH 5.5-5.8, but for a bunch of red, geranium, marigold and malachite, the pH value is 6.2-6.5. 3. The blue-eye chrysanthemum matrix is mixed well and then filled in the basin, and the matrix does not need to be compacted and leveled gently in the process of filling, otherwise it will change the physical properties of the matrix and reduce the air permeability of the matrix. 4. The fine sprinkler is used to pour through the bottom water, and the size of the water droplets should not impact the soil surface and keep the soil surface smooth. After watering, use the fungicide to irrigate again, the commonly used agent is chlorothalonil. 5. Soaking seeds properly can promote germination and increase germination rate. The seeds with thin seed coat can be soaked in cold water, those with thick seed coat can be soaked in warm water or hot water, and very small seeds can not be soaked in hot water. For example, sweet pea and black-eyed Susan soaking seeds overnight can increase the germination rate and make the germination faster. Sowing principle 1. Sowing density pot sowing can sow one or more seeds per hole according to the actual situation. Sowing in the seedling pot, the general variety can sow 1 Mel 2 thousand seeds per square meter. First, according to the area of the sowing pot, the seeds are evenly divided into several parts, one for each pot. 2. Sowing larger seeds can be evenly sown on the substrate, or strip sowing, smaller seeds, such as petunia, goldfish grass, can be mixed with clean fine sand before sowing. Very large seeds, such as sweet peas and cyclamen, can be sown on demand. 3. The depth of sowing and the depth of sowing with soil cover are determined by the size of seeds and the light requirement of seed germination. In general, the sowing depth of seeds is 2-3 times the diameter of seeds. Some varieties, such as Petunia, Corydalis, Starry Flower, and four Seasons Begonia, need light to germinate, do not need to cover the substrate, and sow directly on the soil surface; some varieties need to be slightly covered, such as a string of red, goldfish, and calyx flowers; and some seeds should be slightly thicker and sown deeper, such as ornamental millet. The recommended covering material is coarse vermiculite, which has good water retention and air permeability. 4. After water spray sowing or mulching, spray water again with a fine spray nozzle and water thoroughly, so that the seeds are in full contact with the substrate and mulching materials. 5. Cover blue chrysanthemum with glass, plastic film or plastic film on the sowing pot to maintain air humidity and keep warm in winter. Summer can not cover the film, cover the film can not be sealed, both sides must be ventilated. 6. Shading must be shaded if sowing in summer, otherwise the light is too strong and the water evaporation is exuberant, which will affect the seed germination. Sowing method 1. To prepare sowing soil, it is best to use Cuiyun's sowing soil. 2. The soil used for sowing small seeds had better be screened first, then use the leaky fruit basket commonly used at home, put the fine soil under the sun, and first use the screened branches to cover the bottom, because there are holes the size of small fingers at the bottom of the seedling tray. Fine soil is easy to lose, just can use these large guys, and then put the fine soil until the hole is filled. Fine soil is placed on the surface in order to better infiltrate with small seeds and facilitate germination. In fact, sowing soil with Cuiyun is not a big problem without sieving. Cuiyun's sowing soil itself is also thinner. 3. The humidity of the sowing soil should be appropriate, and it is appropriate to hold the hand into a ball and release the hand. Some people may ask, isn't it the same for seeds to be buried and then sprayed with water? It is really different. Everyone who has used it knows that the cultivated soil is very light, and the wettability of the dry soil is very poor. After spraying water, it floats, and it is very difficult to wet, so it is necessary to pour less water to stir and mix the soil. 4. Put the thick soil left after sifting on the lower part of the seedling plate hole and the fine soil on top. 5, spray water: make the soil surface fully moist, if there is water on the hand, you can spray with its 500 times dilution solution, which is conducive to germination. 6. Sowing: after dipping the seeds with toothpicks in water, stick the seeds one at a time and put them in the center of the hole. It is best to press the coated seeds slightly into the soil. Small seeds are generally light-loving, do not need to cover the soil, it is best to have a hole, after sowing, put the seedling plate into the bottom basin with water, let the water slowly infiltrate. Large seeds dislike light, the seeds should be covered with soil, cover the seeds, and it is best to put them in a cool, dark place before germination. The dwarf hates light, so the plastic film can be covered with black film. Seedling plate is only suitable for small seed sowing, such as geranium, blue chrysanthemum, golden lotus and so on had better be sowed directly in the small seedling basin. 7. Spray water after sowing until the soil is completely wet, and then cover it with plastic film. Do not remove the plastic film before germination, it is best to spray water once a day, and then take off the plastic film after germination to give the seedlings normal light. Make your own small family greenhouse. Put the seedling tray in such a small family greenhouse. Cover the lid until it germinates. The greenhouse is placed in a cool place when the temperature is high, and when the temperature is low, you can bask in the sun during the day and take it back to the house at night. It should be noted that once seedlings sprout, you must let them bask in the sun, otherwise a day or two may be in vain. When the seedlings are almost ready, take out the seedling plate and let the seedlings receive sunshine in a well-ventilated place. It is best to let the soil have a dry-wet cycle in a day or two. Blue chrysanthemum sowed in a large basin, separated by a 2~3CM, and then moved out after germination, a pot of a seedling. Seedlings with small seeds are generally more resistant to transplantation and can be moved when the seedlings are slightly larger. It is best to bring some soil when transplanting and pay attention to proper shading for a few days after transplanting. 8. After budding, it should be ventilated and sunny, and the soil should not always be wetted, otherwise the stem will wither easily. The first summer rain was reported, and the blue chrysanthemum also appeared small yellow buds. It doesn't matter if a large seed is a single direct seeding, but it is best if it is mixed with multiple seeds. Temperature is given according to the requirements of specific varieties, and the germination temperature of most seeds is between 20 and 25 ℃. Too high and too low temperature will directly affect the germination rate of seeds. Blue-eye chrysanthemum germination temperature is 18-20 degrees, sowing does not need to cover soil 2. Humidity blue-eye chrysanthemum after sowing water management is very important. In winter, when the soil temperature is low at night, there is little water loss, so there is no need to replenish water or less water at the seedling stage; if the soil temperature is high, spray water should be sprayed according to the actual needs at the seedling stage. When raising seedlings in summer, water evaporates very quickly, and water must be replenished at any time according to the actual situation. If the seed is very fine, in order to avoid the erosion of water, the method of soaking basin can be used to replenish water. 3. Light, except that some varieties such as cyclamen need darkness during germination, most seeds are favorable for germination under light conditions. Seeds must be exposed to light after germination, otherwise the seedlings will grow too much. 4. After uncovering the seeds and germinating, the mulch should be uncovered in time. 60% of 70% of the seeds should remove the membrane after the cotyledons are unfolded to prevent the seedlings from overgrowing. At the same time, the humidity of the substrate should be maintained so that the cotyledons of some ungerminated seeds protrude successfully from the seed shell. 5. when the transplanted seedlings grow to be suitable for transplanting, they should be planted or planted in time, otherwise it is easy to cause excessive growth of seedlings and production delay. The time of transplanting all kinds of seedlings is different, which should be decided according to the actual situation. Maintenance and management of blue-eye chrysanthemum culture methods 1. Summer safety. Blue chrysanthemum is said to be afraid of heat, but last year both trees were safely placed on the windowsill. 2. The florescence is early and the number of flowers is not small. The blue-eye chrysanthemum on the windowsill sees the flowers more than half a month earlier than the one in the open air, which may be due to the lower temperature in the open air. As for the amount of flowers, just watch the film. This is the picture from half a month ago, when there were already a lot of flowers. 3. Under the condition of long flowering period and sufficient light, the flower closes late. I paid special attention to the first flower on the windowsill and bloomed for 17 days. The reason should be less wind and rain on the windowsill. If it's the one in the open air, thank you for no more than a week. In addition, the windowsill is close to the interior, if the indoor light is turned on early, it can prolong the flowering time of the blue eye. I was startled to watch it open at more than 8 o'clock one night. There is no need for sunshine (this is one of the key points of flower selection on the windowsill). As long as the blue eye chrysanthemum has enough light, the windowsill without sunlight can be opened, and it can be opened on a cloudy day if there is enough scattered light. Main points of breeding 1. The temperature is given at an appropriate temperature according to the requirements of specific varieties, and the germination temperature of most seeds is between 20 and 25 ℃. Too high and too low temperature will directly affect the germination rate of seeds. two。 The management of moisture after humidity sowing is very important. In winter, when the soil temperature is low at night, there is little water loss, so there is no need to replenish water or less water at the seedling stage; if the soil temperature is high, spray water should be sprayed according to the actual needs at the seedling stage.

When the transplanted seedlings grow to be suitable for transplantation, they should be planted or planted in time, otherwise it is easy to cause excessive growth of seedlings and production delay. The time of transplanting all kinds of seedlings is different, which should be decided according to the actual situation. The way of propagation of blue-eye chrysanthemum is sowing or cutting propagation. Spring sowing takes place in March and autumn sowing takes place in September. The land with sufficient sunshine should be selected for planting, and half of loam and rotten leaf soil should be used in potted plants, and an appropriate amount of river sand should be added. Blue chrysanthemum can be used in flower border, or cut flowers, water culture period is longer. Culture and reproduction 1. Prepare to sow soil. 2. The soil used for sowing small seeds had better be screened first, then use the leaky fruit basket commonly used at home, put the fine soil under the sun, and first use the screened branches to cover the bottom, because there are holes the size of small fingers at the bottom of the seedling tray.
