How to propagate colourful leaf grass, the propagation method / sowing medium should be selected.

Colourful leaf grass is famous for its unique leaf color, in addition, the breeding method is simple, so more and more people plant it. When it grows to a certain stage, it needs to reproduce, so how does it reproduce? The editor will introduce to you several common breeding methods of colored leaf grass.

How does Colored Leaf Grass reproduce

At present, the common propagation methods of colourleaf grass are cutting, sowing and tissue culture. Among them, cutting is suitable for potted flowers, sowing is suitable for large-scale propagation, tissue culture is generally used to cultivate new varieties, suitable for botanists who study colored leaf grass.

I. Cuttage method of Colored Leaf Grass

1. Time selection

Theoretically, cutting can be carried out all year round, but in most areas, the lower temperature in winter is not conducive to rooting after cutting, so cutting is often carried out in spring and summer, especially from March to April.

2. Select branches

Select branches from 1-2-year-old strong colored leaf grass plants, usually the branches with terminal buds are the best.

3. Make cuttings

Cut the selected branches into cuttings 5-10 cm long, trim the leaves at the base, retain 3-5 leaves, and need 3-5 nodes on each cuttage. The excess leaves are cut off to avoid the loss of nutrients.

4. Cuttage

After making cuttings, how does colourful leaf grass reproduce? The cuttings will be cut in the prepared basin soil, and then the soil near the cuttings will be compacted, appropriate watering to keep the soil moist, but do not allow stagnant water in the basin.

5. Post-management

After cutting, keep it in a cool and ventilated place, keep the temperature not lower than 18 degrees, and pay attention to the moist condition of the soil. Generally, it can take root in 7-10 days, and a thin liquid fertilizer can be applied after 2 weeks. Then normal maintenance can be carried out in accordance with the breeding method of colored leaf grass.

Second, how to sow coloured leaf grass

1. When will the colourful leaf grass be sown

Generally speaking, it takes 5 months from sowing to transplanting, so the sowing time depends on the time on the market. For example, if you want colourful grass to be on the market in October, you need to sow in May, except that it is not suitable to sow in winter. The other three seasons can be sown, and the best time is March-April.

2. Selection of matrix.

How does colourful leaf grass reproduce when sowing? First of all, we should select a good matrix, the most suitable matrix is a mixture of perlite and peat soil, the proportion is 3:1, and before use, the substrate needs to be disinfected. Generally, soak in 75% chlorothalonil wettable powder for 30 minutes and then dry.

3. Sowing seeds

Sowing is the most suitable breeding method for large-scale houses, but because the seeds are relatively small, in order to spread evenly, it is necessary to mix the seeds with fine soil, and then scatter 2-3 seeds in each hole. Cover with 2-3 mm thick soil, then compacted and watered.

4. Management

Sowing needs to be controlled at about 20 degrees, and seedlings can emerge in 10-15 days. After emergence, the temperature needs to be controlled at 16-18 degrees, after the true leaves grow out, they can be cultivated into seedlings, and after the seedlings grow to 6-10 cm, they can be cultivated in soil.

Color leaf grass color leaf sketch guide: how to raise color leaf grass / how color leaf grass how to breed color leaf grass name piece color leaf grass culture methods and matters needing attention introduction of color leaf grass perennial herbs, foliage flowers. It is often used to decorate flower beds, meeting places and theatres, and can also be used as leaves for flower baskets and bouquets. The breeding methods are sowing and cutting, like temperature and cold tolerance, and pay attention to the prevention and control of diseases and insect pests. Species name: color leaf grass alias: color leaf amaranth: multi-color leaf herbs-foliage water: like to be moist, water should be watered in summer, otherwise it is easy to wilt. And often spray water to the leaves to maintain a certain degree of air humidity. Fertilizer: apply more phosphate fertilizer to keep the leaves bright. Do not apply too much nitrogen, otherwise the leaf surface will be dim. Soil: the soil is required to be loose and fertile, and the general garden soil can be used. Temperature: like warmth, strong cold tolerance, suitable temperature for growth is 15 ℃ 25 ℃, overwintering temperature is about 10 ℃, freezing injury is easy to occur when it drops to 5 ℃. Light: like the sun, but avoid the scorching sun. Flower words: a desperate relationship. The morphological characteristics of color-leaf grass are perennial herbaceous plants, the old plants can grow into subshrubs, but the plant shape is ugly and the ornamental value is low, so they are mostly cultivated for one or two years. The plant height is 50~80cm, and most of the cultivated seedlings are below 30cm. The whole plant is hairy, the stem is quadrangular, and the base is lignified. Leaves opposite, ovoid, apex long acuminate, margin with obtuse teeth, leaves can grow 15cm, green leaves, with yellowish, pink, scarlet, purple and other colorful markings. Terminal raceme, flowers small, light blue or light purple. Nutlets are smooth and shiny. Color leaf grass varieties, varieties, five-color leaf grass (Var verschaffel news) leaves have yellowish, pink, scarlet, dark red and other color markings, strong growth. The yellow-green leaf type ChartreuseTyPe is ten small yellowish green with many dwarf branches. FringedTyPe leaf margin is lobed and corrugated leaf type (Large-LeavedType) has large oval leaves and tall plants. The temperature-loving plant of colourful leaf grass has strong adaptability, the temperature in winter is not less than 10 ℃, when it is hot in summer, it is slightly shaded, likes sufficient sunshine, and sufficient light can make the leaves bright. The distribution area of colourful leaf grass is a kind of flower with strong adaptability. It can also be seen in many places in our country, especially in the south. Gardens are often cultivated all over our country. The main cultivation bases are Jiangsu, Zhejiang, Anhui and other places. According to the breeding method, colourful leaf grass can be divided into two types. 1. Seed propagation type: sowing and reproduction can maintain the good characters of the variety. This type has the following five leaf types: [big leaf type] (large~leaved type), with large oval leaves, tall plants, few branches and uneven leaves. [color leaf type] (Rainbow type), the leaf is small, long oval, the apex is pointed, the leaf surface is smooth, the leaf color is red, orange-red, yellow-green, white green spot and so on. [wrinkled edge] (Fringed type), the leaf margin is cracked and corrugated, the cracks and ripples vary greatly, and there are many kinds of leaf colors. [willow leaf type] (Willow~leaved type), leaves slender, willow-shaped, leaf margin irregularly lobed and serrate. [yellow-green leaf type] (C color leaf grass hartreusetype), small leaves, yellowish green, sunburn resistance, short and much branched plants. Vegetative reproduction type: some non-twist, low-twist or those who can not keep the character of the variety by sowing and breeding. The common variety of horticulture is var.verschaffeltii, with light yellow, pink, scarlet, dark red and other color markings on the leaves. In addition, the ornamental grass (C.pumilus), which is native to the Philippines and Sri Lanka, is also highly ornamental. Plant height 15-20 cm, perennial herbs, stems recumbent. Leaves opposite, rhombic, 2-3 cm long, dark brown, margin green, light abaxially. The flower blue-green panicle is 10-12 cm long. C.thyrsoideus, subshrub, 80cm high, bright green leaves, heart-shaped oval. Margin coarsely serrated. Bright blue flowers, verticillate inflorescences, with 3-10 flowers, arranged in a spike. The flowering period is from November to December, and potted flowers are observed in winter. There are about 150 species of Colored Leaf Grass, which are found in Asia, Africa, Oceania, tropical and subtropical regions. The common varieties of potted flower cultivation are: Honghong, velvet red, dwarf peach red and other varieties. Sex likes the environmental conditions of warm and humid climate, soft and sufficient sunshine and fresh air, the suitable indoor temperature in winter is 20 ℃ to 25 ℃, the lowest overwintering temperature can not be lower than 10 ℃, the leaves turn yellow and fall off when the temperature is too low, and the plants below 5 ℃ die. Potted plants require sandy cultivated soil rich in humus, loose and fertile, with good drainage and air permeability. For the demand for water, we should keep the basin soil and the environment moist and moderate, avoid drought and prevent waterlogging, so as to avoid dehydration and discoloration of leaves and soft rot of roots. The light is soft and sufficient, and the leaf color is brilliant, but the leaf surface is rough and loses glossiness due to the strong sunlight in the clear sky in midsummer. And in the shady environment, the leaf color is not bright. Leaf grass likes sandy loam with rich humus and good drainage. When potted, bone meal or compound fertilizer was used as base fertilizer, and organic liquid fertilizer was applied once every 10 to 15 days during the growing period (stopped in midsummer). In the seedling stage, the heart should be picked many times to promote the lateral branches and make the plant full. After flowering, 2-3 nodes of the lower branches can be retained, the rest can be cut off and new branches can be reissued. The suitable temperature for the growth of colourful leaf grass is about 20 ℃. Cold Dew moves indoors back and forth, and the room temperature should not be lower than 10 ℃ in winter. Watering should be dry and wet, and keep the basin soil moist, otherwise the roots are easy to rot. Colorful leaf grass, also known as old age to change, perennial herbaceous flowers. The plant height is 30-50 cm and the branches are few. Leaves opposite, rhomboid ovate, thin, can be more than 15 cm long, the edge has deep thick teeth, green leaves, yellow, red, purple and other colorful markings, hence the name colourful leaf grass. The common varieties of potted flower cultivation are: Honghong, velvet red, dwarf peach red and other varieties. Colored leaf grass likes warmth, and pot sowing and cutting methods can be used for reproduction. Sowing at 18-25 degrees, seedlings can emerge in 1-2 weeks, cuttings are divided into ground cuttings and water cuttings, water can be used to cool half a cup of boiled water, cuttings select 2-3 nodes in the middle and upper part of the branches, remove the lower leaves, and place them in water. When the white water root grows to 5-10 mm, it can be planted in a pot. It takes 5-7 days in spring and autumn, and it can take root in one day in summer. The daily management of colourful leaf grass is relatively simple, just pay attention to pick the heart in time, promote new branches, form a plump ball, and develop clumps of plants. Inflorescence formation should be removed so as not to affect the ornamental effect of leaves. Colorful leaf grass is an excellent potted foliage flower, can also be used in summer and autumn flower beds, bright colors, very beautiful. At the same time, you can cut branches and leaves to do cut flowers, or the ingredients of flower baskets, and can also be planted in the same pot with duckweed, which is a good material for decorating the living room and study. The disease control of colourful leaf grass is easy to occur quenching disease at seedling stage, so attention should be paid to the disinfection of sowing soil. Leaf spot disease is harmful during the growing period, so spray it with 50% topiramine wettable powder 500 times. In indoor cultivation, shell insects, red spiders and whitefly are easy to occur, which can be controlled by 1000 times of omethoate EC. Seedling quenching disease is a kind of disease often encountered in sowing and breeding melon and leaf chrysanthemum. it can be seen that the leaves of seedlings are green, that is, lodging and death, or rot or dry up. The disease is mainly caused by Rhizoctonia solani and Rhizoctonia solani. The pathogen overwinters in the soil or on the diseased remains, and is spread by seeds or water droplets. For the prevention and treatment of balsamina balsamina, see the prevention and treatment of balsamina balsamina. In the seedling stage, the coring should be carried out according to the set plant shape, and if you want to cultivate a tufted and plump garden column, you must coring the trunk of the seedling. If you want to cultivate it into a conical shape, the trunk will be coring many times instead of coring the lateral branches. If you do not pick seeds, you should coring the inflorescence in time. The seed collection of Colored Leaf Grass grassland is produced in Java, Indonesia. It is a perennial herb of the genus Labiatae. The varieties cultivated in green space or family are artificial horticultural varieties. When the gardening variety is potted, the plant height is about 30 cm, the leaves are opposite, ovate or round, and there are purple, pink, red, yellowish, orange and other colored markings on the green leaf substrate. Colourful leaf grass comes from the tropics, so it likes warmth and is not cold-resistant, the overwintering temperature should not be lower than 5 ℃, and the suitable temperature for growth is 20-25 ℃. It can also tolerate semi-shade, avoid hot sun exposure, and can be placed indoors for a short time, requiring it to be planted in loose, fertile and well-drained soil. If only for ornamental use, the growing period needs to pick the heart several times to promote branching and make the shape plump. If you want to harvest seeds, you'd better not pick your heart. In Buhai area, colourful leaf grass blossoms from August to September. Before flowering, you should choose III. The brightly colored plants remain seeds; when flowering, the inflorescences should be artificially pollinated in the form of brush and pollen brush stigma, and then isolated by paper bags to prevent hybrid degradation. In the early stage of flowering, some phosphorus and potassium fertilizers should be applied to ensure the nutritional requirements when fruiting. Generally, after flowering and fertilization, as long as the sun is sufficient and there is no harm to diseases and insect pests, coloured leaf grass can bear seeds, and one month after seed setting, the seeds can be harvested, dried and preserved for sowing in the coming year. As the seeds of colourful leaf grass are small, they should be dried with pods when harvested. It should be noted that the seeds harvested by themselves will certainly have some degeneration and variation after sowing in the second year, and bad plants should be eliminated from the seedling stage. The method of propagation is usually sowing and propagation can maintain the good characters of the variety. For those who can not keep the variety character by sowing and propagation, it is necessary to adopt cutting propagation. Under the condition of high temperature greenhouse, the four seasons can be sown in pots, usually in March in the greenhouse. Half of the fully mature humus soil and plain sandy soil were mixed into the seedling basin, and the seedling pot containing fine sandy soil was soaked in water, then soaked according to the sowing method of small seeds, slightly covered with thin soil and covered with glass plate or plastic film to keep the basin soil moist, water supply and pipe protection. The optimum temperature for germination was 25 ℃ to 30 ℃ and germinated in about 10 days. After emergence, the seedlings are divided into pots for 1 to 2 times. The seeded seedlings have different leaf colors, so you can choose the good and eliminate the bad at this time. Cuttings can be carried out all the year round and are easy to survive. Can also be combined with plant coring and pruning for softwood cutting to cut full and growing branches. Cut 10cm or so and insert it into the clean and sterilized river sand. The embedded part must often have leaf nodes to take root, shade maintenance after cutting, and keep the basin soil moist. When the temperature is higher, it will take root faster. During this period, the basin soil must not be too wet to avoid rotting roots. It will take about 15 days to root and survive. Can also be inserted in water, with cool half a cup of boiled water can, cuttings select the growth of the branches in the middle and upper 2ml 3 nodes, remove the lower leaves, placed in the water, when there are white water roots up to 5Mel 10mm can be planted into the pot. [1] it is better for potted plants to be small, with an inner diameter of 10 cm in general. After 20 to 30 days of maintenance, the plant height up to 15 cm can be placed and watched. The place with strong diffuse light in the south window should be selected for indoor placement to keep the pot soil dry and wet, the air fresh and the environment clean. Outdoor maintenance, sparse shade environment should be put in summer. Rarefied liquid fertilizer can be applied 3 times in the whole year. If the main stem grows too high, you should pick the heart in time. In the case of not harvesting seeds, it is best to remove it at the initial stage of flower panicle formation, because most of the plant posture is loose after heading, reducing the ornamental effect. At the beginning of October, it overwinters in medium and high greenhouses, and the old plants can be renewed in this period. At the same time, the soil can be changed in combination with turning the basin. The maximum inner diameter of the basin is 14 cm, and then it is inconvenient to put it. Nutlets of colourful leaf grass are easy to fall off naturally when they are ripe, and they are also afraid of being blown by storm, so they should be cut off and threshed one by one when the sepals turn yellow. although some fallen seeds can sprout and sprout, they are not resistant to cold, so they can not play the role of self-sowing and reproduction. Water cutting propagation 1. Colorful leaf grass preparation container: the cutting container can be a jar, or the upper part can be cut off with a mineral water bottle, and the lower part can be filled with water. The container must be clean, the water quality must be clean, and it is best to take a large cola bottle to store water for more than one day for cutting and follow-up management. 2. Cutting cuttings: when the main branch or the side branch that passes through the heart is about 4 nodes or 10 cm long, select the thick stem, leaving only 1 to 2 nodes of opposite leaves at the base, cut off the upper part, the cut should be smooth, there is no wound of extrusion and tear. Then, cut off the lowermost pair of leaves of the cuttings, concentrate on the base of every 3 to 5 cuttings, bundle them together with white thread pine, and wait for water insertion. 3. Water insertion management: it is generally best for cuttings to enter water from 3 cm to 4 cm from the mouth of the bottle. After that, put it in the scattered light place, pay attention to change the clear water (reserve water storage) every 2 to 3 days, and pay attention to make up for the falling water level in the bottle due to evaporation every day. Generally, under the condition of 18 ℃ to 25 ℃, white root can be seen in 7 to 10 days. 4. Timely potting: the adventitious root of colourful leaf grass is easy to grow at the stem node, and the straight and sturdy stem will also sprout, which provides conditions for cuttings to take shape as soon as possible. When it is seen that there are several 1 cm to 2 cm adventitious roots at the base of the cuttings, they can be put on the pot or planted in time. Pay attention to careful operation, do not damage the root system, generally in the shade of flowers for about 10 days, you can enter the normal management. Propagation skills: the seed soil of Colored Leaf Grass is a mixture of peat soil and fine sand, which can be sowed. The seeds of Colored Leaf Grass are light seeds, so there is no need to cover the soil after sowing, the optimum temperature for germination is 20 ~ 25 ℃, keep the substrate moist, and germinate for 8 ~ 10 days. Cutting can be carried out in four seasons, rooting in about 20 ℃ in a week, and water cutting is also easy to take root. When the sowing seedlings grow a pair of true leaves, the pot soil is peat soil. 2. River sand, adding enough base fertilizer, often topdressing during the growing period, including topdressing calcium superphosphate and bone meal. When the temperature is kept above 20 ℃, the seedling stage depends on the purpose of culture. If you want to cultivate plump plants, you should remove the trunk to promote the growth of lateral branches. If you want to cultivate a conical plant, you don't have to remove the trunk. Coloured leaf grass has strong adaptability and simple management. The temperature adaptation range is 10-30 ℃, which is lower than 10 ℃. The plant growth is stagnant and the plant is dead below 5 ℃. Colored leaf grass is a light-loving plant, sufficient light, can make the leaves bright, but in summer high temperature should avoid direct sunlight, high temperature and strong light will destroy the pigment, cause the increase of chlorophyll, lead to the plant color is not bright, or even green, affecting the ornamental. Therefore, it should be properly shaded when it is hot in summer. There is no shade in other seasons, because dim light will make the leaves gray. The leaves of colored leaf grass are large and thin, and the water supply should be ensured. When the soil is dry, the color of the leaf surface should fade, especially in summer, the basin soil should be moist. At the same time, water should be often sprayed to the ground and leaf surface to improve air humidity, but there should be no stagnant water. Stagnant water is easy to cause root rot and leaf shedding. In winter, watering is controlled, and the greenhouse temperature is maintained at 15 ℃, which ensures that the dry-wet cycle is obvious and the cycle is short. The requirement of fertilizer is not high, the rarefied fertilizer based on nitrogen fertilizer is applied once or twice a month in the growing season. After the inflorescence appears, if the seed is not collected, it should be picked in time so as not to consume nutrition and at the same time make the plant shape scattered and affect the ornamental value. If you want to collect seeds, you will harvest when the inflorescence changes from green to yellow. The function and use of colorful leaf grass is colorful, many varieties and easy to breed. As a widely used foliage flower, it can not only be used as small foliage flower display, but also can be equipped with picture flower bed, and can also be used as flower basket and bouquet with leaves. Indoor furnishings are mostly small and medium-sized potted plants, choose a set of pots with light color and smooth texture to set off the gorgeous leaf color of colored leaf grass. In order to make the plant beautiful, the unopened inflorescences are often cut off and admired on the short table and windowsill. Courtyard cultivation can be used as a flower bed, or plant edge. Several pots of colored leaf grass can also be used to decorate the venue and the vestibule of the theatre with flowers. The flower language of color leaf grass: desperate love color leaf grass picture of color leaf grass sowing and cutting propagation method

The leaves of colored leaf grass are very beautiful, so some people call it the change of old age, the leaf color of colored leaf grass is bright, the variety is diverse. The difficulty of artificial propagation is not high, and the method of sowing and cutting can be used to propagate it.

Coloured leaf grass

First, sowing seeds

Sowing and raising seedlings of Colored Leaf Grass can produce plants with rich changes in leaf color. When the conditions are suitable, the seeds can be sowed at any time throughout the year. Open fields in South China are often sown in 3mura-April, and most of them are sown in greenhouses in the north from February to March. Spring sowing in the north is sown in greenhouse, sowed with loose bed soil, sifted the bed soil, loaded with human sowing bed or seedling tray, slightly compacted and scraped flat, watered with spray pot, sown seeds about 20 grams per square meter, mixed with fine sand and sowed, the ground temperature was controlled at about 20 ℃ after searching fine soil, and the seeds emerged in 15 days. After emergence, the temperature dropped to 16 MULTHI / MULI 181. After the true leaves grow, divide the seedlings and cultivate them into seedlings in containers. The daytime temperature during the seedling stage was controlled at 18.201. Watering should be appropriate, and the seedling bed should not be too wet. When the seedling grows to a height of 6ml / 10cm, it should be planted in a pot, and cultivated in the open field until the temperature is warmer and stable. Gradually cool down and refine seedlings 5-7 days before planting. The water control at the seedling stage should be moderate so as not to make the leaves lose water and wither and prevent the excessive growth of seedlings and the occurrence of diseases.

Second, cuttage

Color leaf grass is prone to adventitious roots, and some varieties have poor fruiting, so they can only use the method of cutting propagation to raise seedlings. Cutting seedling raising can be carried out in four seasons, especially in spring and autumn. Cut the upper part of the branch 5-7 cm as cuttings and cut off the leaves. Put it into frogstone, perlite or other substrates and keep it under the condition of 15 ℃ and 20 min, 5 Mel can take root in 7 days. Water plug can also be used. After taking root, it is transplanted into the basin.
