Leaves ovate to oblong, basal leaves stipitate, upper leaves sessile. The head flower is solitary, the tubular flower is yellow, and the tongue flower is white. Pink, blue, purple and pink, etc. Some are tongue-shaped double petals, or tongue-shaped flowers are tubular. Growth habit: masculine, fertile and moist, avoid continuous cropping and waterlogging. Trollius chinensis, also known as Trollius chinensis and Lotus Leaf, is a perennial herbaceous flower of Trollius of Trolliaceae. The leaves are shaped like lotus bowls, and most of the flowers are orange. They can be used to decorate potted plants on balconies and windowsills, and can also be placed on indoor desks and shelves for appreciation. Leaves alternate, long-stalked, round or nearly kidney-shaped, with wavy obtuse angles at the edges. Flowers solitary, axillary. When cultivated in the wild, they bloom in summer and autumn. Horticultural varieties include dwarf trollius, double petals, semi-double petals, mosaic and so on. This flower is native to Peru, Chile and other places. I like warm, humid and sunny environment, and the suitable growth temperature is 18-24℃. In summer, it is afraid of high temperature, the growth above 35℃ is inhibited, it is not cold-resistant, and it can tolerate short-term low temperature of 0℃. Biennial flowers are often planted in the north. Trollius chinensis is often used for sowing and propagation, and can also be used for cutting with tender branches. Generally, it is sown in March and blooms in July and August; Sowing in June and flowering on National Day; Sowing in September and flowering in the Spring Festival; Sowing in 65438+February, "May Day" blossomed. When sowing, soak in warm water at 40-45℃ for one night, then plant in a shallow basin, which is filled with plain sand and covered with fine sand with a thickness of about 65,438+0 cm. After sowing, keep it moist in the sunny place and emerge in about 65,438+00 days. Two true leaves of seedlings were planted in pots at different times. Cutting at room temperature 13- 16℃ in spring, cutting off 3-4 leaves of stems and vines with the length of 10 cm, leaving the top leaves, inserting them into the sand, keeping them moist, taking root in 10 days, and putting them into pots after 20 days. When the stems of Trollius chinensis are creeping, scaffolding is needed. When the seedlings grow to 3-4 true leaves, it is necessary to remove the heart and promote its multi-lateral branches. Before putting it on the shelf, the core should be removed and tied evenly on the shelf to form various decorative forms. After flowering, cut off the old branches and wait for the new branches to blossom. For aging plants, when the temperature reaches above 10℃, the upper branches and leaves can be cut off at the base, and basic fertilizer can be applied and placed in a greenhouse at about 7℃ to promote the formation of new branches and clusters. Trollius chinensis should be cultivated in sandy loam rich in organic matter, with PH value of 5-6. Fertilize once every 3-4 weeks in the general growth period. Loosen the soil in time after each fertilization to improve aeration, which is beneficial to root system development. Trollius likes wet and is afraid of waterlogging, and the soil moisture is kept at about 50%. Water should be watered less frequently during the growing period, once every 2-3 days in spring and autumn, once a day in summer, and spray water on the leaves in the evening to maintain a high humidity. Water should be reduced after flowering to prevent the branches from growing vigorously. Trollius likes sunshine, but is not tolerant of shade. It should be cultivated in sunny places in spring and autumn, properly shaded in summer, put in a cool and ventilated place in midsummer, enter the room in the middle of 5438+ 10 in the north, and maintain in sunny places. The room temperature should be kept at 10- 15℃, and the fertilizer and water should be properly controlled. Peacock grass for indoor flower cultivation: Peacock grass is an annual herbaceous flower of Tagetes in Compositae. The plant is short, with a plant height of 20-40 cm, compact plant type, clustered branches and purple stems. The leaves are opposite, pinnately divided, the lobes are lanceolate, and there are obvious oil glands at the leaf margin. Flowers are born on the top of the head, with dark red outer ring and yellow inner ring, so they are also called red and yellow grass. Because of repeated interspecific hybridization, in addition to red and yellow, pure yellow, orange and other varieties have been cultivated, as well as single-petal and compound-petal varieties. The flowering period lasts from May Day to November 1st. Peacock grass has strong adaptability, likes warm sunny environment, bears drought, and has no strict requirements on soil and fertilizer. Peacock grass is cold-resistant and can resist the attack of the first frost. Spend less when it is hot in summer. The seedling raising period is short. It takes only 70 days from sowing to flowering, and seedlings can be raised in greenhouse in early spring without heating, and then planted in courtyard, flower bed or potted plant after late frost. The germination rate of malachite seeds is low, and the common sowing method is only 10%-30%. To plant malachite grass, containers such as boxes and pots should be used to raise seedlings, and sandy loam should be filled in them to create a soft and breathable germination environment for seeds. Sow the seeds directly on the soil surface, and cover them with straw or newspaper to keep them in close contact with the soil. Commonly used watering can, can't let the topsoil dry. After the seeds germinate, remove the cover. February orchid for indoor flower cultivation: Latin name: Orychophragmus; alias: Orychophragmus: Cruciferae, Orychophragmus; adaptation area: ecological distribution from southeast China to east China: ground cover plants >; Morphological characteristics of cold-type narrow-leaf lawn: the flowers are light blue and purple, and the flowering period is from March to May. Growth habit: Suitable for indoor flower cultivation with semi-shade, cold tolerance and humidity. Shell flower: scientific name: Molucella laevis, alias: collar flower, genus of Celastraceae: shell flower of Labiatae. Origin: west Asia characteristics: annual herb, height 40- 100cm. Small white flowers, six in turn, fragrant calyx like shells, green is very beautiful. Key points of cultivation: the suitable temperature for germination is 15-25℃, and the suitable temperature for growth is 20-30℃. Planting requirements: sow in a nursery basin or choose a fertile vegetable garden with good drainage, water and irrigate, apply soil thinly, keep the humidity on the border, and germinate in about 10 day. Sow in stages and provide flowers in a unified way. The land needs fertile and good drainage system. 5-6 pieces should be transplanted with soil and fertilized and watered after survival. In order to promote multi-branching, topping can be carried out at an early stage. This kind of flower is easy to manage, grows healthily and has few diseases, but there are liriomyza sativae from time to time, so attention should be paid to prevention and control. Platycodon grandiflorum: scientific name: alias: bell flower, hexagonal flower, pedicel grass and hexagonal lotus Origin: China and Japanese Habit: I like warm, sunny or semi-cloudy environment. Not resistant to high temperature, humidity and cold climate. It needs fertile and well-drained clay. Propagation: mainly by sowing and dividing plants. Sowing, sowing in September, and emergence 2 weeks after sowing. Sowing in spring in April and flowering in June of the following year. Branch plants, all in autumn. Cultivation: extensive cultivation management, open cultivation, and choose places with deep and fertile soil. Fertilize 1 time every month during the seedling growth period to keep the soil moist and prevent dry cracking. When flowering, plants are prone to lodging and can be cultivated or supported properly. In early winter, the aboveground parts gradually wither. Cut off the dead leaves, and the underground roots can overwinter in the open field. Application: Platycodon grandiflorum is bright blue in color and shaped like a bell, but it expands into a balloon when it sprouts, so it is called "China balloon". It is suitable for arranging flower borders and decorating rock gardens, and is also an excellent material for cut flowers and potted plants. The fragrance of indoor flower cultivation: tufted, coralline, phlox. Native to the eastern part of North America, it is a perennial evergreen perennial herb flower, which is a unique variety in the Fulukou strain. In recent years, tufted phlox has attracted much attention in landscaping. It is not only an excellent ground cover flower with high coverage and strong ornamental value, but also has the characteristics of simple planting, strong adaptability, drought resistance, cold resistance and salt tolerance. The tufted phlox blooms every spring and autumn. The flowers are slightly fragrant and cup-shaped, and the colors are dark pink, rose purple, white, reddish and yellow. Its plants are robust, can grow in various types of soil, and can also grow well in slightly dry soil. This variety germinates early, and leaves and flowers germinate synchronously. The requirement of fertilizer for tufted fulukou is not strict, but during the growth period, attention should be paid to applying base fertilizer, adding organic fertilizer during soil preparation, and applying 500 kg to 1000 kg per mu. Apply a small amount of nitrogen fertilizer and phosphorus fertilizer in the growth period, mainly nitrogen fertilizer in the long leaf period, and phosphorus fertilizer can be sprayed in the flowering period. The propagation methods of tufted phlox are mainly cutting and rameting. Cutting propagation can be carried out from May to July. Select robust plants and use semi-lignified branches with the length of 7- 10cm as cuttings. Cutting substrate can be clean river sand or vermiculite. The ramet propagation can be carried out in spring and autumn. Dig out the seedlings, separate the plants with interwoven roots to form independent seedlings, and plant them at the spacing of 15cm ~ 20cm, and 2 ~ 3 plants can be planted in each hole. After planting, the soil should be compacted, thoroughly watered once, and watered again after 3 days. You can loosen the soil and moisturize it once in about 4 days, and then turn to conventional management. In summer, clumps of phlox should be pruned in time, especially after flowering, and open branches and irregular branches should be cut off. Don't use lawn mower to push and cut, only use hand scissors to trim. Weeds are found and need to be removed manually. Don't spray herbicides. In the dry season, the cluster phlox is prone to the harm of red spider, and the symptom is that the leaves turn yellow. In extremely cold areas, seedlings in the field can be covered with a layer of leaves or branches, which can avoid freezing injury caused by severe cold. The tufted phlox has many excellent characteristics of perennial flowers and has many garden uses: it can be planted in bare open space; Can be dotted on the edge of the green belt; Can be planted between cracks in rocks; Can be mixed with tulip, bellflower, dwarf day lily and other flowers; It can be planted under big trees to beautify the loess in the open air; It can also be planted in the slope area, which not only beautifies the slope, but also reduces soil erosion. Mimosa in indoor flower cultivation: Mimosa, also known as Mimosa, Huhehe and Afraid of Ugliness, is a perennial herb of Mimosaceae, with tufts as high as 1 m and barbed bristles. When leaves are touched, they close and droop, showing shame. The flowering period is 3-65,438+00 months and the fruiting period is 5-0 months. Why are mimosa "shy"? The petiole base and compound leaf base of mimosa have an enlarged part, which is called leaf pillow. There are vascular bundles in the center of occipital lobe and many parenchyma cells around it. In normal times, each cell is full of enough water, so it expands and makes the occipital bone stand upright, so the leaves stretch, but once stimulated, the water contained in the occipital cells flows into the intercellular space, so the occipital bone becomes soft and the leaves close and droop. Mimosa's hometown is in tropical America, where there are often storms. This "shy" characteristic of mimosa is very beneficial to protect itself from wind and rain. It is also like a shy girl standing at the window. When she meets a stranger, she immediately closes the window, which is quite interesting and ornamental. The whole plant of Mimosa mimosa has little toxicity, and it is used as medicine to soothe the nerves. Fresh leaves can be mashed and applied externally to treat herpes zoster. Violet, which originated in tropical America, is now widely used in indoor flower cultivation in tropical regions of the world, also known as osmanthus and violet. They are annual, biennial or perennial herbs of Viola in Cruciferae, and they are one of the famous flowers in Europe. The plant height is 20-70 cm, and the whole plant has gray-white stellate hairs. The stems are erect and much branched. Leaves alternate, oblong or oblanceolate, 3-5 cm long. Racemes are terminal or axillary, with potato chips on both sides, stout pedicels, flower diameter of 2 cm, 4 petals with long claws, and petals spreading in a cross shape. Flowers are purplish red, light red, light yellow, white and so on. , slightly fragrant. The flowering period varies with different varieties, including spring violets, which bloom in April and May. Violets in summer bloom from June to August; Violets in autumn bloom from July to September. Violet likes warm winter, cool summer and well-ventilated environment. It can withstand a short-term low temperature of -5℃ in winter and avoid extreme heat in summer. Fertile, loose and moist soil should not be fertilized too much, otherwise it is not conducive to flowering. Like sunlight, it is a long-day plant. Inadequate lighting and ventilation are prone to pests and diseases. The propagation of Cymbidium goeringii was sown in early September, and the optimum temperature for germination was 20℃. In early spring, summer violets are planted in the greenhouse. Autumn violets are sown in late autumn. Violet is a straight-rooted plant with underdeveloped fibrous roots, so it is suitable to divide seedlings before the real leaves unfold, with less damage to the root system and more soil. Double-petalled varieties that are not easy to bear fruit can also be cut or propagated by dividing roots.
