According to the propagation method, colored-leaf grass can be divided into two types. 1. seed propagation type: sowing and propagation can maintain the excellent characteristics of varieties. There are five leaf types in this type:

Big leaf type, large oval leaves, tall plants, few branches and uneven leaves.

Rainbow-shaped, with small, rectangular leaves and smooth tips with red, orange-red, yellow-green, white and green spots.

Fringe-shaped, with wavy cracks at the leaf edge, great changes in cracks and ripples, and more kinds of leaf colors.

Willow leaf type, slender leaves, willow-like, with irregular serrations at the edge.

Hartreusetype), small leaves, yellow-green, fire-resistant, short and multi-branched. Asexual reproduction type: a person who is partially untwisted, low-twisted, or unable to maintain variety traits through sowing and reproduction. The common horticultural variety is var.verschaffeltii, with mottled leaves, including light yellow, pink, vermilion and crimson. In addition, it is native to the Philippines and Sri Lanka and has high ornamental value. Plant height 15 ~ 20cm, perennial herb with recumbent stems. The leaves are opposite, rhombic, 2 ~ 3 cm long, dark brown, with green edges and pale back. The blue-green spike length of the flower is 10 ~ 12 cm. It is 80 ~ 100 cm high, with bright green leaves and an oval heart shape. The edges are coarsely serrated. The flowers are bright blue, and 3 ~ 10 flowers are arranged in panicles. Flowering11~ 65438+February, potted in winter.

Edit the ecological habits of this paragraph.

Thermophilic plants, with strong adaptability, the temperature is not lower than 10℃ in winter, slightly shaded when it is hot in summer, and like abundant sunshine, which can make the leaves colorful.

Edit this section cultivation management

There are about 150 species of colored grass, which are produced in tropical and subtropical areas of Asia, Africa and Oceania. Common varieties of potted flower cultivation are: red rainbow, velvet red, short pink and so on. Sexually, I like warm and humid climate, soft and abundant sunshine and fresh air. The suitable indoor temperature in winter is 20℃ to 25℃, and the minimum wintering temperature should not be lower than 10℃. If the temperature is too low, the leaves will turn yellow and fall off, and the plants below 5℃ will die. Potting requires sandy culture soil to be rich in humus, loose and fertile, with good drainage and air permeability. For the demand of water, it is necessary to keep the soil and environment moist and moderate, avoid drought and waterlogging, and avoid dehydration and discoloration of leaves and soft rot infection of roots. The light is soft and sufficient, and the leaves are gorgeous and remarkable. However, it is forbidden to make the leaves rough and lose luster under the direct sunlight in sunny summer. In a shady environment, the leaves are not bright. [2]

Yecaoxi is a sandy loam rich in humus and well drained. When potted, bone meal or compound fertilizer was applied as base fertilizer, and organic liquid fertilizer was applied every 10 ~ 15 days during the growing period (application was stopped in summer). At the seedling stage, the heart should be picked many times to promote the development of lateral branches and make the plants full. After flowering, you can keep 2 ~ 3 lower branches, cut off the rest and send new branches again. The optimum temperature for the growth of colorful grass is about 20℃, and the cold dew moves indoors before and after, and the indoor temperature should not be lower than 10℃ in winter. At this time, watering should be dry and wet alternately, and the basin soil should be kept wet, otherwise the roots will rot easily.

Collect seeds

Color-leafed grass is a perennial herb of the genus Color-leafed grass in Labiatae, which is native to Java, Indonesia. Now it is cultivated as a horticultural variety in green space or at home after artificial transformation. Horticultural varieties are about 30 cm high when potted, with opposite leaves, oval or round, and purple, pink, red, light yellow, orange and other color markings on the green leaf substrate.

Color-leafed grass comes from the tropics, so it likes warmth and is not cold-resistant. The overwintering temperature is not lower than 5℃, and the suitable growth temperature is 20-25℃. It likes sunny environment, and can tolerate semi-shade to avoid exposure to the scorching sun. It can be placed indoors for a short time and needs to be planted in loose, fertile and well-drained soil. If it is just for viewing, it needs to be picked several times during the growing period to promote branching and make the shape full. If you want to harvest seeds, you'd better not dig your heart.

In Buhai District, colorful grass blooms from August to September. Choose III before flowering. Colorful plants to preserve seeds; When flowering, the inflorescence should be artificially pollinated in the form of brushing the stigma with a brush, and then isolated with paper bags to prevent hybridization degradation. At the beginning of flowering, some phosphorus and potassium fertilizers should be applied to ensure the nutritional needs when bearing fruit.

Generally, after flowering and fertilization, colored grass can bear seeds as long as there is plenty of sunshine and no pests and diseases. When seeds mature one month after seed setting, they can be harvested in separate plants, dried in the sun and stored for sowing next year. Because the seeds of colored grass are small, they should be dried with pods when harvesting. It should be noted that the seeds collected by ourselves will definitely degenerate and mutate after sowing in the second year, and the bad plants will be eliminated at the seedling stage from small to large.

breeding method

Usually, sowing and propagation can maintain the excellent characters of varieties. Some varieties cannot be maintained by sowing and propagation, and need cutting propagation.

Under the condition of high temperature greenhouse, potted plants can be planted all year round, usually in the greenhouse in March. Fully decomposed humus soil and plain sandy soil are evenly mixed and put into a nursery basin, and the nursery basin filled with fine sandy soil is soaked in water, and then sown according to the sowing method of small seeds, and covered with thin soil, glass plate or plastic film to keep the soil moist, water supply and management. The optimum temperature for germination is 25 ~ 30℃, and it takes 10 days for germination. After emergence,/kloc-0 to 2 times, and then divide the seedlings into pots. Seeded seedlings have different leaf colors. At this time, the best ones can be eliminated.

Logging can be carried out all year round, and it is very easy to survive. You can also combine plant coring and pruning to carry out softwood cutting and cut off the full-grown branches. Cut about 10cm and insert it into clean and disinfected river sand. The buried part must always have leaves to take root. After cutting, it must be shaded and maintained to keep the pot soil moist. When the temperature is higher, the roots will take root faster. During this period, the pot soil should not be too wet to avoid root rot. Roots can grow and live for about 15 days. You can also put it in water and cool it with half a cup of boiling water. When cutting, select 2-3 nodes from the middle and upper parts of the fully grown branches, remove the lower leaves, put them in water, and plant them in a pot when the white water roots grow to 5- 10 mm [1].

Potting method

Colored leaf grass

Small potted plants with leafy grass are better. Generally, when the seedlings grow, they will be put into a test tube with an inner diameter of 10cm. After 20 ~ 30 days of maintenance, the plants can be placed for viewing when they reach 15cm. Indoor display should be placed in the place where the south window diffuses light intensity, keeping the soil dry and wet properly, the air fresh and the environment clean. Outdoor maintenance should be kept in a cool environment in summer. Thin liquid fertilizer can be applied three times a year. If the main stem grows too high, it should be picked in time. In the case of not harvesting seeds, it is best to pick them off at the beginning of heading, because most plants are loose and rough after heading, which reduces the ornamental effect. At the beginning of June 10, wintered in the middle and high greenhouse. During this period, old plants can be cut and updated again, and at the same time, they can be changed by turning over the pot. The maximum inner diameter of the basin is 14 cm, which is inconvenient to put again.

Color-leafed grass nuts are easy to fall off naturally when cooked, for fear of being hit by a storm. Therefore, when the sepals become Yellowstone, they should be cut off one by one and threshed. Although some ground seeds can germinate and emerge, they can't play the role of self-sowing and reproduction because they can't resist cold.

Water insertion propagation

1.

Colored leaf grass

Prepare the container: the cutting container can be a jar or a mineral water bottle. The top can be cut off and the bottom can be filled with clean water for later use. The container must be clean and the water quality must be clean, and it is best to store water in another Coca-Cola bottle for more than one day for cutting and subsequent management.

2. Cutting: When the main branch or lateral branch after core removal is 4 knots or about 10 cm long, select the stout stem, leaving only 1 ~ 2 opposite leaves at the base, and cut off the upper part, with smooth incision and no extrusion and tearing injury. Then cut off a pair of leaves at the bottom of the cuttings, concentrate every 3-5 cuttings on the neat base, tie them together with white lines and insert them into the water.

3. Water insertion management: Generally, it is advisable to insert the cuttings into the water from the bottle mouth by 3 cm to 4 cm. After that, put it under scattered light, pay attention to changing fresh water (storing water) every 2 to 3 days, and pay attention to make up the water level in the bottle that drops due to evaporation every day. Generally, under the conditions of 18℃ to 25℃, white roots can be seen from 7 days to 10 days.

4. Potting in time: The adventitious roots of colorful grass are easy to grow except the stems, and the straight and thick stems will germinate.

Color Grass Picture Appreciation (16)

This provides conditions for the formation of drilling cuttings as soon as possible. When there are many adventitious roots from 1 cm to 2 cm at the base of cuttings, they can be potted or planted in time. Pay attention to careful operation, do not damage the root system, and generally maintain it in the shade of flowers for about 10 days before entering normal management.

Colored leaf grass

Seed soil is a mixture of peat soil 1 and fine sand 1, which can be planted. The seeds of colored grass are shiny seeds, and there is no need to cover the soil after sowing. The optimum temperature for germination is 20 ~ 25℃, and the substrate is kept moist for 8 ~ 10 days. Cutting can be done all year round, and it takes 1 week to take root at about 20℃, and it is easy to take root by water insertion. When the seedlings grow 1 true leaves, they should be put into pots, and the pots are peat soil 2, loam soil 1 and river sand 1. It is necessary to add sufficient base fertilizer and topdressing frequently during the growth period, including topdressing calcium superphosphate and bone meal. When the temperature is kept above 20℃, it is decided whether to collect core at seedling stage according to the purpose of culture. If you want to cultivate plump plants, you should pick the trunk to promote the growth of lateral branches. If you want to cultivate a conical plant shape, you don't have to remove the trunk. Colored leaf grass has strong adaptability and simple management. The temperature adaptation range is 10 ~ 30℃, which is lower than 10℃, and the plants stagnate and die below 5℃. Color-leafed grass is a light-loving plant, and its leaves will become bright under sufficient light. But avoid direct sunlight when it is hot in summer. High temperature and strong light will destroy pigments, increase chlorophyll, lead to dark or even green color of plants, and affect ornamental. Therefore, it is necessary to shade properly when it is hot in summer. You can't shade the sun in other seasons, because dim light will darken the leaves. Color-leafed grass leaves are large and thin, so it is necessary to ensure water supply. When the soil is dry, the color of the leaves will fade. Especially in summer, the basin soil should be kept moist, and the ground and leaves should be sprayed with water frequently to improve the air humidity, but the water can not be accumulated, which is easy to make the roots rot and the leaves fall off. Water is controlled in winter, and the greenhouse temperature is maintained at 65438 05℃ to ensure that the dry-wet cycle is obvious and short. The demand for fertilizer is not high, and the thin fertilizer mainly containing nitrogen fertilizer is applied 1 ~ 2 times a month in the growing season. After the inflorescence appears, if you don't pick the seeds, you should pick them in time to avoid consuming nutrition, and at the same time make the plant shape messy and affect the ornamental value. If you want to collect seeds, you have to wait until the inflorescence changes from green to Huang Shi for harvesting.

It has bright colors, many varieties and is easy to propagate. It is a widely used foliage flower, which can be displayed as a small foliage flower, a flat flower bed, and also used as a leaf accessory for flower baskets and bouquets.

Indoor furnishings are mostly small and medium-sized potted plants, and pots with light color and smooth texture are selected to set off the colorful leaves of colorful grass. In order to make plants beautiful, unopened inflorescences are often cut and placed in low places and windowsills for appreciation. Garden cultivation can be used as flower beds or plant edges. You can also arrange pots of colorful grass in the venue and the front hall of the theater, and flowers are in full bloom.

The seedling stage is prone to damping-off, so we should pay attention to the disinfection of sowing soil. Leaf spot is harmful in the growth period, so 50% thiophanate wettable powder should be sprayed 500 times. In indoor cultivation, scale insects, red spiders and whiteflies are easy to occur, which can be prevented by spraying 40% omethoate EC with 1000 times solution. Seedling damping-off disease is a common disease in pumpkin sowing and seedling raising, and it is often seen that seedling leaves are green and lodging and die, or rot or dry. The disease is mainly caused by pythium melonis and Rhizoctonia solani. Pathogens overwinter in soil or diseased bodies and spread through seeds or water droplets. For the prevention and control methods, see the prevention and control of Impatiens damping-off. Pick the core according to the set plant shape at seedling stage. If you want to cultivate into clusters and plump cylinders, you must pick the core of the seedlings. If you want to cultivate into a cone, you should pick the core of the trunk many times, not the side branches. If you don't pick seeds, you should pick the core of inflorescence in time.

Color-leafed grass is also called perennial herbaceous flower. Plant height is 30-50 cm, with few branches. The leaves are opposite, rhombic-oval, thin, up to 15 cm, with deep coarse teeth at the edge, green leaves with yellow, red, purple and other color stripes, hence the name colored leaf grass.

Common varieties of potted flower cultivation are: red rainbow, velvet red, short pink and so on.

Colored-leaf grass likes warmth and can be propagated by pot planting and cutting. Seeding at 18-25 degrees, 1-2 weeks can produce seedlings. Cut into two kinds, water can be inserted with half a cup of boiled water cooled in the air. For cutting, you can choose 2-3 nodes in the middle and upper parts of fully grown branches, remove the lower leaves and put them in water. When the white water roots grow to 5- 10 mm, pots can be planted. It takes 5-7 days in spring and autumn, and generally takes one day to take root in summer.

The daily management of color-leafed grass is relatively simple, as long as attention is paid to picking the heart in time, promoting the development of new branches, forming plump balls and cultivating plants. Inflorescence generation should be removed to avoid affecting the ornamental effect of leaves.

Colored leaf grass is an excellent potted foliage flower, which can also be used as a flower bed in summer and autumn. It is colorful and very beautiful. At the same time, you can cut branches and leaves to make ingredients for cut flowers or flower baskets, or you can plant a pot with Commelina communis, which is a good material for decorating living rooms and study rooms.

Edit the propagation law of this paragraph

Color-leafed grass is a perennial herb. Old plants can grow into subshrubs, but they are ugly in appearance and have low ornamental value, so they are cultivated for one or two years. The plant height is 80 cm, and most of the cultivated seedlings are controlled below 38 cm. The whole plant is hairy, the stem is quadrangular, the base is lignified, the single leaf is opposite, oval, the apex is long and tapering, and the edge has blunt teeth. The leaves can be as long as l5cm, and there are light yellow, pink, vermilion and dark red markings on the leaves of five-color clover, which makes it grow vigorously. Yellow-green leafy grass is ten small yellow-green grasses with many short branches. The frilled leaves are cracked, and the wavy big leaves have large oval leaves. The plant is tall, with few branches and uneven leaves. There are many varieties of various leaf types, and new varieties are still being cultivated, which makes colored grass occupy an important position in flower decoration. I like warm, sunny and well-ventilated environment, and my cold tolerance is weak. Generally, it is safe to overwinter above 10℃ in winter. When the temperature is too low, the leaves are easy to turn yellow and fall off, and it needs proper shading in summer when the temperature is high. As a common potted ornamental plant, it can also be used as a flower bed layout material, suitable for planting in flower bed trees, and can also be used as a material for flower arrangement decoration. Under the condition of high-temperature greenhouse, sow with small seeds, cover with thin soil, cover with glass plate or plastic film, keep the basin soil moist, and manage the water supply. The optimum temperature for germination is 30℃, and germination takes about 10 day. After emergence,/kloc-0 to 2 times, and then divide the seedlings into pots. Seeded seedlings have different leaf colors. At this time, the best ones can be eliminated. Grass likes fertile sandy loam with good drainage. Organic compound fertilizer should be applied every 10 ~ 15 days during the growth period. When fertilization is stopped in midsummer, it is forbidden to spray fertilizer on the leaves to avoid burns and rot. Color-leafed grass likes light, and excessive shading can easily lead to pale leaves and weak plant growth. In addition to keeping the basin soil moist, we should often spray the leaves with clear water to wash away the dust accumulated on the leaves and keep the leaves colorful. It should be repeated several times at seedling stage to promote the development of lateral branches for about 15 days before the roots can survive. You can also put it in water and cool it with half a cup of boiling water. When cutting, select two middle and upper branches, remove the lower leaves, put them in water, and plant them in a pot when the white water roots grow to 10 mm [2].
