How to breed a string of red, when to sow seeds / spring or autumn sowing

There are many places in life where you can see a string of red figures, and many flower friends will keep it at home to watch, one of the reasons is that a string of red has a lot of functions, and reproduction is also very simple, so how does a string of red reproduce and survive? Let's take a look at the two most common ways to reproduce a string of red.

How does red breed?

Saffron is often propagated by two methods, namely sowing and cutting, in which sowing can be divided into spring sowing or autumn sowing, which can reproduce a large number of saffron at a time, while cuttings are mainly used for pot culture, and the operation is simple and the rooting time is fast. it can be propagated without affecting the growth and flowering of the mother plant.

The breeding method of a string of red

First, a string of red seeds are sown and propagated

1. When will a string of red seeds be sown

It can use spring sowing or autumn sowing, in which spring sowing usually takes place in early March, and after sowing, it can blossom from September to October, and autumn sowing is in August. After sowing, it blossoms in May of the following year. As autumn sowing requires reasonable maintenance in winter, spring sowing is a good choice for ordinary flower friends.

2. Sowing method

⑴, the use of sowing is a string of red how to breed? Prepare the basin soil before sowing, apply a small amount of base fertilizer in the soil, and then pour water for 1-2 days to ensure that the soil is fertile and moist, which is beneficial to the rooting of sowing.

⑵, sow the seeds evenly on the soil, and then cover with 1-2 cm thick soil. As the soil has been watered thoroughly before, the soil will be relatively moist, so there is no need to water after sowing. Put it in a semi-shady place and cover it with plastic film to keep warm and moisturizing.

⑶, keep the soil moist, if it is too dry, it can be soaked in water from the bottom of the basin, generally 8-10 can germinate, but you need to wait until it grows seedlings and then properly supplement fertilizer, and then manage normally according to a string of red maintenance skills, usually about 100 days from sowing to flowering.

Second, a bunch of red cuttage propagation

1. Time

The time is generally chosen in March-May or September-October, which can be carried out in combination with pruning, for example, when the top is removed, the buds can be used as cuttings, which can reduce the maintenance steps.

2. Methods

Cut about 12-15cm branches from the robust plant, put it in a cool place to dry naturally, and then cut the branches in the potted soil, generally cutting 1-2 branches in each flowerpot, and then pour water thoroughly to ensure that the temperature is about 20 degrees Celsius. If it is too dry, it can sprout for about a week, and then transferred to the sun for maintenance.

A string of red Salvia splendens Ker-Gawler A string of red pictures: how to raise a string of red / how to reproduce a string of red business cards a string of red Salvia splendens Ker-Gawler a string of red breeding methods and precautions A string of red is also known as firecracker red, which is a plant of the genus Salvia in Labiatae. A string of red inflorescences with slender, bright red color, long flowering period and strong adaptability are the most commonly cultivated herbaceous flowers in Chinese cities and gardens. In recent years, there has been a new development in the application of sage ornamental plants abroad. Sage (red lip) and pink calyx sage (a string of blue) have been bred many new varieties. China has also introduced and carried out small batch production, which has played a good effect in the layout of urban landscape. A string of red flowers is family love, which represents the heart of love. A string of red dietotherapy or medicinal value Huanhua network medical information and health dietotherapy information for reference only, can not be used as a basis for diagnosis and medical treatment. Any health problems should consult professional health care personnel, the treatment of any disease, please follow the doctor's advice. The ultimate task of protecting flowers: to love yourself, proceed from reality and follow the doctor's advice. For disease, do not be careless, do not postpone, do not give up hope, face it bravely, warm the silent world with love, and protect the inner flower field with your heart. The medicinal parts of a bunch of red herbs are whole herbs, which can be harvested during the growing period, fresh or dried. Taste and efficacy are sweet and flat. Clear heat, cool blood, reduce swelling. Indoor potted plants, flower beds, flowers, flower beds, flower belts, potted cultivation techniques A string of red planting distance is about 40 cm, it is suitable for fertile and loose soil or sandy soil rich in humus. In the peak growing season, it can be applied with phosphate-containing liquid fertilizer once or twice to promote flowering. A string of red usually do not like flood, otherwise it is easy to produce yellow leaves, fallen leaves, resulting in large plants and sparse flowers. During the growth period, plastic surgery should be often removed to control the height and branching of the plant. Cause the inflorescence to grow and enlarge and blossom neatly. Spring sowers bloom from September to October, and the old overwintering plants in the greenhouse also have flowers from May to June, but not as many as in summer and autumn. Although the branches and leaves grow vigorously in hot summer, there are few flowers. A bunch of safflower is late. If the seeds are harvested, they should be sowed in the greenhouse or hotbed at the beginning of March, which can advance the flowering date and help to bear fruit well. A string of red seeds are easy to fall, or are often not fully mature because of cool autumn, so they are often used in pots and transferred to the greenhouse for overwintering. Cutting new branches in the second year makes it easy to take root. In the hotbed above 15 ℃, cuttings can be cut at any time. The cuttings take root in about 10 to 20 days, and can be planted in 30 days. The cuttage seedling to flowering stage is faster than the seedling, and the plant height is also easy to control. The plant of the late transplant is short and the growth potential is weak, but it has little effect on the florescence, the flowering is still luxuriant, and it is easier to arrange. For the purpose of seed collection, it is best to use seedlings. National Day with a string of red, cut in early July, when the weather is hot, should pay attention to shade, rainy days should pay attention to rain and drainage. When a bunch of red seedlings grow from 3 to 4 pairs of true leaves, each plant should have at least 4 lateral branches and move to the flower bed when the ends of the branches show flowers. If phosphate fertilizer is applied before flowering, flowering is especially good. A string of red calyx fades for a long time but does not fall, for ornamental arrangement, the residual flowers need to be removed at any time, and the breeding method of keeping flowers colorful and red is mainly sowing and propagation, and can also be used for cutting propagation. The sowing time can be carried out from March to early June in spring (from late February to early March in Shanghai). There is no need to cover soil after sowing, and the temperature is kept at about 20 ℃. It can germinate in about 12 days. Cutting propagation can be carried out in summer and autumn (flower color variation is large, can be sown in advance, divided into flowers and colors, and then propagated by cutting method). [sowing and propagation] generally sowing seeds from March to June. The seeds are larger, 260,280 seeds per gram. The optimum temperature for germination was 21 Mel 23 ℃, and germinated 18 days after sowing. If sowing in autumn, indoor disk sowing can be used, the room temperature must be above 21 ℃, and the germination is fast and neat. When it was lower than 20 ℃, the germination potential decreased obviously. In addition, a string of red is a light-loving seed, which does not need to be covered with soil after sowing, and can be removed and placed around the seed with light vermiculite, which not only does not affect the light transmission but also plays a moisturizing effect, and can improve the germination rate and uniformity, and the general germination rate is 85% and 90%. [cuttage propagation] May-August is the best. Select sturdy and full branches, 10 cm long, insert them into disinfected rotten leaf soil and keep them for 20 ℃. They can take root in 10 days after planting and transplant in 20 days. A string of red gardens are often used as the main material of flower beds and flower borders, and are often used as potted plants in the north. The cultivation of a string of red is also very common in the world, especially in Europe and the United States and Japan, although it is not included in the ranking of output value, the Goldsmith seed Company of the United States, the Italian French Company, the French company Bodger and the British company Floranova have sold a string of red seeds every year. At the same time, new varieties are constantly on the market, especially the dwarf potted varieties are updated very quickly. Therefore, the appearance of a string of red has changed a lot. Although the cultivation history of saffron in China is not long, it is the most common and most widely used in urban environmental layout. Every year, a string of red still plays a leading role in a grand festival, estimated at 500000-1 million pots in big cities and 50-100000 pots in small and medium-sized cities. However, in the application of varieties, red is the main, and old varieties are the main. White, purple and pink are rarely used. Until the 1990s, dwarf varieties entered our country, and the status of a string of red has been strengthened because of its rich colors. At the same time, there has been a new development in the application of sage ornamental plants abroad, and many new varieties of sage (red lip) and pink calyx sage (a string of blue) have been cultivated. China has also introduced and carried out small batch production, which has played a good effect in the layout of urban landscape. A series of red diseases to control fungal infection [black spot]: mainly infect leaves, petioles and shoots. At the beginning of the disease, the leaves appear purple-brown to brown spots on the front, and when enlarged, they are mostly round or amorphous dark-brown spots. Can be sprayed with carbendazim, methyl thiophanate, daconine and other drugs. [powdery mildew]: the white powdery substance appeared on both sides of the tender leaves, and the early symptoms were not obvious. after the appearance of 3Murray in the powdery mildew layer for 5 days, the leaves showed water stains, gradually lost green and turned yellow, and caused the leaves to fall off in case of serious injury. During the onset period, carbendazim and triadimefon can be sprayed, but the effect of Guoguang Inna is the best. [leaf blight]: most leaf tips or leaf edges invade, initially yellow spots, then rapidly expand inward into irregular spots, seriously damaged whole leaves withered up to 2 ppm 3, the diseased parts are chlorotic and yellowing, brown dry and shedding. In addition to strengthening the management of fertilizer and water, the diseased branches and leaves should be cut off in winter, the underground fallen leaves should be removed, the sources of initial invasion should be reduced, comprehensive control should be taken when the disease occurs, and fungicides such as carbendazim and methyl thiophanate should be sprayed. The disease is mainly for prevention. Germicidal agents are sprayed regularly in high temperature, high humidity or overcast and rainy seasons, and stone-sulfur mixture is sprayed on the dormant stage of the seedlings to carry out comprehensive sterilization, so as to ensure the healthy growth of the seedlings and the strong growth of the seedlings. itself resists a certain amount of disease invasion. Insect pest control 1. Diamondback moth is mainly the larvae of yellow diamondback moth, green diamondback moth, Spodoptera litura, mulberry brown diamondback moth and flat diamondback moth, which eat a lot of leaves in high temperature season. Control method: once found, it should be sprayed immediately with 90% trichlorfon crystal 800 times, or with 2.5% fenpropathrin EC 1500 times. 2. The shell insects are mainly white wheel scale, Japanese tortoise wax scale, red wax scale, brown soft wax scale, blow cotton scale, bran shield scale, snake eye scale and so on. The harmful characteristics of the scale insects are piercing and sucking the juice of a string of red tender stems and young leaves, resulting in poor plant growth, mainly caused by high temperature and humidity, poor ventilation and poor light. Control method: during the peak hatching period of the nymph, it can be sprayed with 2 000 times of 25% prochloraz wettable powder. 3. Aphids are mainly a bunch of red tube aphids and peach aphids, which absorb the sap of young organs of plants, harm tender stems, young leaves and flower buds, and seriously affect the growth and flowering of plants. Prevention and control method: spray with 2000 times of imidacloprid wettable powder in time. 4. Rose three-leaf wasp is mostly in the larval stage, dozens or more than a hundred clusters harm, which can eat up the young leaves of the plant in a short time, leaving only a few main leaf veins, seriously endangering the normal growth of the plant. Prevention and treatment: a small number of potted plants can pick leaves with a large number of larvae and trample them to death. It appears in large quantities and can be sprayed with 4000 times of phoxim EC. 5. Cinnabar spider mites can occur for 10 to 15 generations a year. Adult mites, young mites and nymph mites are concentrated on the back of the leaves, and the eggs are mostly laid on both sides of the veins of the dorsal leaves or under the gathered filaments. Each female mite can lay 50 to 150 eggs, and the maximum time is 500. the time to complete the first generation is only 10 to 13 days at 23 ℃ to 25 ℃, and about 7 to 8 days at 28 ℃. The high temperature and drought season is rampant, which often leads to a large number of dense white spots on the front of the leaves and yellowing even withered spots on the back of the leaves. Prevention and control method: once found, spray with 2000 times of 25% Baileba wettable powder in time. 6. The beetles are mainly copper green beetles, black velvet beetles, white star beetles, small blue and white beetles, etc., often gnawing on new leaves, shoots and buds with adults, seriously affecting plant growth and flowering. Prevention and control method: make use of the false death of adults to vibrate and kill in the evening. Make use of the phototaxis of adults, trap and kill with black light. When adults feed, spray with 1000 times 50% malathion EC. In addition, there are other hazards, such as lamp moth, night moth, bridge worm, bag moth, leafhopper, bugs and so on. Corresponding control measures can be taken according to the harm characteristics of different insect pests. A string of red ecological habits a string of red, sexual preference for warm, humid, sunny environment, fear of cold, avoid dry and hot climate. The suitable temperature is 20-25 degrees, the temperature is below 5 degrees, the leaves will gradually turn yellow and fall off. Saffron has strong adaptability, but grows well in loose, fertile and well-drained soil. Potted a string of red, the basin to apply sufficient base fertilizer, the early growth should not be more watering, can be irrigated once every two days, so as to avoid leaves yellowing and falling off. Entering the peak growth period, we can appropriately increase the amount of water and begin to apply topdressing twice a month, which can make the flowers bloom luxuriantly and prolong the flowering period. When the seedling has 4 leaves, it begins to pick the heart and promote the plant to be more branched. Generally, it can be picked out 3 times for 4 times. In addition to the above-mentioned self-sowing reproduction ability, a string of red can also be propagated by artificial sowing and cutting. Sowing can be carried out from March to April, and the seedlings will be transplanted and planted when the height of the seedlings is 5ml / 10cm. Cuttings can be carried out when the temperature is above 15 degrees. Choose a sturdy branch that is slightly hardened, cut it into a paragraph about 6 centimeters long, insert it into a half-deep insert bed, and sprout new roots in half a month. It can also be propagated by dividing roots from old plants. Potted plants should be placed in a string of red places to pay attention to air circulation, fertilizer and water management should be appropriate, otherwise the plant will rot or be damaged by aphids, red spiders and so on. When insect pests are found, 40% dimethoate 1500 times solution can be used to control them. The morphological characteristics of a string of red, herbs. Stem ca. 80 cm tall, smooth. Leaf blade ovate or ovoid, 4 to 8 cm long and 2.5 to 6.5 cm wide, apex acuminate, base rounded, both surfaces glabrous. Verticillate inflorescences with 2 to 6 flowers, crowded into terminal false racemes, bracts ovoid; calyx campanulate, 11 to 22 mm long, scarlet, upper lip entire, lower lip 2-lobed, teeth ovate, apex acute; Corolla red, Corolla tube protruding calyx, ca. 3.5 to 5 cm, red pilose outside, glabrous inside tube; stamens and style protruding beyond Corolla. Nutlets ovate, 3-angled, smooth. The florescence is from July to October. Originally from Brazil. It is commonly cultivated in parks in Shanghai and Nanjing for viewing. The distribution area of a string of red saffron | North China | Northeast China | East China | South China | Northwest China | Central China | the propagation mode of a string of saffron in southwest China is mainly sowing propagation, which can also be used for cutting propagation. The sowing time can be carried out from March to early June in spring (from late February to early March in Shanghai). There is no need to cover soil after sowing, and the temperature is kept at about 20 ℃. It can germinate in about 12 days. Cutting propagation can be carried out in summer and autumn (flower color variation is large, can be sown in advance, divided into flowers and colors, and then propagated by cutting method). [sowing and propagation] generally sowing seeds from March to June. The seeds are larger, 260,280 seeds per gram. The optimum temperature for germination was 21 Mel 23 ℃, and germinated 18 days after sowing. If sowing in autumn, indoor disk sowing can be used, the room temperature must be above 21 ℃, and the germination is fast and neat. When it was lower than 20 ℃, the germination potential decreased obviously. In addition, a string of red is a light-loving seed, which does not need to be covered with soil after sowing, and can be removed and placed around the seed with light vermiculite, which not only does not affect the light transmission but also plays a moisturizing effect, and can improve the germination rate and uniformity, and the general germination rate is 85% and 90%. [cuttage propagation] May-August is the best. Select sturdy and full branches, 10 cm long, insert them into disinfected rotten leaf soil and keep them for 20 ℃. They can take root in 10 days after planting and transplant in 20 days. The culture method of a string of red pictures and a string of red

A string of red breeding methods a string of red, also known as firecracker red, firecracker red, wall red and so on. Herbs of Labiatae. Originally from Brazil. Morphological characteristics: the plant height is 25 ~ 50cn^ the stem is quadrangular. Leaves alternate, cordate or ovate. Flowers terminal, raceme, kaleidoscope long, bright red. There are many cultivated varieties of a string of red, which is usually called a string of red, purple and white. Because of the different height of its plants, it is often divided into three types: high, medium and short.

Growth habits like a warm and humid climate and plenty of sunshine, and avoid direct sunlight in summer. Not resistant to drought and cold. The requirements for soil are not strict, and sufficient fertilizer and water are required. The florescence is from May to October.

Breeding method

The main results are as follows: (1) sowing method: the suitable temperature of sowing is 150.211, usually the spring sowing time is from March to June, and the autumn sowing time is from September to October. Pot sowing is often used when the seedling quantity is small, and border sowing is often used when the seedling quantity is large. The seeds soaked for 16 hours or 20 hours were mixed with soil or sand, then sprinkled evenly on the soil surface, slightly suppressed, covered with a small amount of soil and then poured with water, covered with transparent plastic sheet to moisturize, after most seeds germinated, the plastic sheet was removed, and water was sprayed with a fine-hole pot in time to prevent drought from sprouting. A string of red seeds like light, the soil must not be too thick after sowing, or the seeds and the soil surface can be compacted without covering the soil.

Cutting method: cutting is often carried out in June-July in early summer or September-October in autumn. Cutting is easy to rot to death when the temperature is too high, and it is not easy to take root when the temperature is too low. The cuttings should select the growing and full shoots, remove the basal 1-2 pairs of leaves, and the top leaves cut off the leaf surface of l/3~l/2, so as to reduce the water evaporation of the scion after cutting. Watering can be a little more for the first time, and it is appropriate to sprinkle and irrigate less frequently in the future. Too much water can easily lead to cuttings rot.

It is suitable to cultivate and maintain the soil with loose and fertile loam rich in humus. Usually transplant or pot when sowing or cutting seedlings grow 4-6 true leaves. Generally, dwarf species or middle species are selected in potted plants, and medium or high species are used in ground cultivation. Potted plant per pot, commonly used 10-12 cm diameter of small and medium-sized pots; ground plant spacing 25-40 CN ^-Chuanhong prefer fertilizer and water, generally on the pot planting can first be mixed with a small amount of mature organic fertilizer or compound fertilizer, and then once every half a month to apply nitrogen-based topdressing, the formation of pre-bud application of phosphorus and potassium fertilizer, if only urea nitrogen fertilizer will appear can not form flower bud growth. Summer watering must not be carried out at noon, otherwise it is easy to have rotten roots. In order to make the plant plump, a string of red also needs to be reshaped and pruned, repeatedly hit the head, remove the weak branches, stop starting 30 days before flowering, and cut off the abortive flowers at any time after flowering in order to keep the flowers blooming continuously.

Pest control

Red spider: it often happens in the season of high temperature and dry. Control methods: withered branches, fallen leaves and nursery weeds can be removed in autumn and winter to reduce the number of overwintering mites; during the occurrence period, 40% trichlorotrexol 1 000 × 1 500 times or 40 "dimethoate 1 200 × 1 500 times solution should be sprayed on both sides of the leaves.

Aphids: this insect rarely occurs. When damaged, the young leaves are wrinkled, and when serious, they can be sprayed with 40 times and 1500 times of dimethoate.

Spodoptera litura: larvae are harmful to leaves and flowers. When a small number of larvae occur, the damaged parts are eaten into irregular defects, and in severe cases, the leaves can be eaten. Prevention and control methods: family flower cultivation can be used to catch and kill, when it is serious, it can be sprayed and killed with 50 "fenitrothion 1000 times or 40 ^ omethoate 1 200 times."

Black spot disease: it often damages the seedlings in the seedling stage. At the initial stage of the disease, the damaged plants should be eliminated, and the diluent of carbendazim or chlorothalonil should be sprayed again every 7 to 10 days. A large number of rainy and high temperature periods are likely to occur, which need to be prevented and controlled in time.

6. Horticultural use a string of red flowers, plump plant shape, long flowering period, and strong adaptability, the most suitable for flower bed layout. Potted flowers are often used in halls, balconies or balconies.
