The planting method of ginger lotus prefer yin or yang

Ginger lotus, this is a kind of plant, this ginger lotus blossoms is still quite good-looking, what is the planting method of this ginger lotus? Does Jiang Lotus like Yin or Yang:

Turmeric lotus belongs to the genus Curcuma of Zingiberaceae and is a perennial herbaceous tropical bulbous flower. Because the pink bracts resemble the lotus and belong to the family Zingiberaceae, it is called ginger lotus.

Ginger lotus has a unique flower pattern, bright colors, and the flowering period of ginger lotus is also quite long, as long as 3 months.

1. Bulbs: bulbs with a diameter of more than 1.5cm and more than 3 stored roots should be selected when planting.

2. Flowerpots: ginger lotus flowers should use larger pots, but do not use too deep pots, which are easy to rot.

3. Soil: generally speaking, except the clayey soil is not suitable for ginger lotus, other soils can adapt well. However, in order to grow ginger lotus better, we can choose some sandy soil or slightly acidic soil which can lock in water but has good drainage performance when cultivating potted ginger lotus. Some mature base fertilizers can also be added to the bottom of the pot.

4. Moisture: when you just plant ginger lotus, you must keep the soil moist and have enough water. In the middle of the growth of ginger lotus, it is also necessary to keep the soil moist, but pay attention to drainage, otherwise the wet environment is easy to infect ginger lotus; usually water, remember not to sprinkle water on leaves and flowers.

5. Environment: the suitable temperature for the growth of ginger lotus is 20 ℃ ~ 35 ℃, and it is best to grow in the environment of half yin and half yang. Under natural conditions, if the temperature decreases and the day becomes shorter, the ginger lotus will go into dormancy. Ginger lotus is a tropical flower, so it is necessary to maintain a certain environmental humidity to avoid dry air.

6. Fertilization: the growth rate of ginger lotus will increase after budding, so more nutrition is needed. At this time, we need proper fertilization, and it is best to use compound fertilizer containing nitrogen, phosphorus and potassium at the same time, so that the nutrition is more balanced. It can promote the growth of stems, leaves and flowers of ginger lotus at the same time.

This is the end of the introduction on the planting method of ginger lotus. This ginger lotus is more suitable for breeding in a half-yin and half-yang place.

Understand the knowledge of planting flowers and plants and enrich daily life

Flower planting is a kind of thing that people generally come into contact with in daily life, which has been widely concerned by people all the time, so what are the introductions to flower planting? I believe we also want to know the answer to this question. Now we can better apply it to our daily life through the study of the knowledge of planting flowers and plants.

Introduction of plant planting media

1. Peat: peat is a product of natural swamp formed after thousands of years (also known as peat or peat). It is not only the least coalified coal, but also the most primitive state of coal, aseptic, non-toxic, non-polluting, good ventilation, light weight, water retention, fertilizer conservation, conducive to microbial activities, enhanced biological performance, rich nutrition, is not only a cultivation substrate, but also a good soil mediator, and contains high organic matter. Humic acid and nutrients.

two。 Coconut bran: coconut bran is a coconut shell fiber powder, is a processed coconut by-product or waste. It is a kind of pure natural organic medium which falls off from the processing of coconut shell fiber. The processed coconut bran is very suitable for cultivating plants and is a popular horticultural medium at present.

3. Garden soil: garden soil, also known as vegetable garden soil, pastoral soil, this is a common cultivated soil, because of frequent fertilization and cultivation, high fertility, good aggregate structure, is one of the main raw materials for the preparation of cultivated soil. The disadvantage is that the surface layer is easy to harden when dry, and the ventilation and water permeability is poor when wet, so it can not be used alone. Surface sandy loam with vegetables or legumes is the best.

4. Red jade soil: formed by the accumulation of volcanic ash, it is the most widely used soil medium. This is also the most widely used cultivation medium in Japan. It is a highly permeable volcanic mud with dark red round particles, no harmful bacteria and a slightly acidic PH value. Its shape is conducive to water storage and drainage. The percentage generally mixed with other substances is 30-35%, which is higher than that of peat. The effect is comparable to that of peat.

5. Vermiculite: vermiculite is a natural, non-toxic mineral that expands at high temperatures. It is a rare mineral and belongs to silicate. Its crystal structure is monoclinic, and it looks like mica in appearance. Vermiculite is produced by certain hydration of granite. It usually occurs at the same time as asbestos. Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of soil. In 2000, the total output of vermiculite in the world exceeded 500000 tons. The main producing countries are China, South Africa, Australia, Zimbabwe and the United States.

6. Perlite: perlite Perlite perlite is a kind of acid lava from volcanic eruption, a glassy rock formed by rapid cooling, named for its perlite structure. Perlite deposits include perlite, obsidian and turpentine. The difference between the three is that perlite has an arc-shaped crack formed by condensation, which is called perlite structure, with a water content of 2% 6%; turpentine has a unique turpentine luster, with a water content of 6% 10%; obsidian has a glass luster and shell-like fracture, and the water content is generally less than 2%.

7. Plant stone: the color of plant stone is wax yellow, the surface is smooth and the structure is solid. It is a kind of volcanic stone, which releases a large amount of gas and heat after volcanic eruption. It is porous, light, can quickly absorb nutrients and retain moisture after special temperature, and then processed by high-tech technology after 250 degrees high temperature sterilization. Therefore, it has the characteristics of light weight, drainage, moisturizing and air permeability, and after planting gold stone wet water, the color is golden, and the elegant orchid plants complement each other.

8. River sand: River sand is a non-metallic ore with complex composition, smooth surface and high impurity content, which is caused by the repeated collision and friction of natural stone and water for a long time. The river sand is smooth, relatively clean and comes from a wide range of sources; the river sand is tasteless and the sea sand has a salty taste.

9. Iridescent stone: lovely color, uniform particles, round appearance, no root damage, suitable bulk density, good plant fixation, not easy to decompose, not easy to break, can be used for a long time / has good air permeability and good water holding capacity, has a certain fertilizer retention capacity, while adding imported long-term controlled release fertilizer, rich in trace elements and rare earth elements mineral particles, long-term release, PH is slightly acidic, low EC value. No weed seeds, no germs, no mosquitoes.

10. Sun stone: sun stone is as dry as other pumice. And widely used in South Korea. Slightly acidic, suitable for plant varieties that do not like to change pots and do not need to change pots. In addition to oriental orchids, bonsai, foliage palms, cacti and aquatic plants, it is also suitable for cultivation of general potted flowers and mountain grasses.

11. Maifan stone: Maifan stone is a kind of compound mineral or medicinal rock which is non-toxic, harmless and has certain biological activity. The main chemical composition of Maifan stone is inorganic aluminosilicate. Including SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO, etc., but also contains all the major elements needed by animals, such as K, Na, Ca, Mg, Cu, Mo and other trace elements and rare earth elements, about 58 kinds.

twelve。 Tung sand: Tung sand is a kind of volcanic sand named after Tongsheng, Japan, which contains a large amount of Fe2O3 (iron oxide) in the shape of hard stone sand. Used for the planting of orchids, deciduous plants, etc. Fuji sand is also named after place names and is produced in the area of Mount Fuji in Japan. This medium has good permeability, water storage, fluidity and drainage. Suitable for bonsai, alpine flowers and other plants.

13. Deer marsh soil: a rare substance produced in volcanic areas, generated by the lower volcanic soil, in the form of volcanic sand, pH is acidic, has high permeability, water storage and ventilation. The size of the deer marsh soil is not quite the same. there are many holes. This kind of soil is mainly used for bonsai, orchids, alpine flowers and so on.

14. Pumice: the porosity of pumice is 71.8%, and the water absorption is 50-60%. It is named because it can float on the surface of the water because of its many pores, light weight and unit weight less than 1 g / cu cm. It is characterized by light weight, high strength, acid and alkali resistance, corrosion resistance, no pollution, no radioactivity and so on. It is an ideal natural, green and environmentally friendly product.

15. Diatomite: diatomite is a kind of siliceous rock, mainly distributed in China, the United States, Denmark, France, the Soviet Union, Romania and other countries. It is a biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2, which can be expressed by SiO2?nH2O, and the mineral composition is opal and its varieties. Introduction of China's diatomite reserves of 320 million tons, prospective reserves of more than 2 billion tons, mainly concentrated in East China and Northeast China, of which large scale, more work has been done in Jilin, Zhejiang, Yunnan, Shandong, Sichuan and other provinces, although widely distributed, but high-quality soil is only concentrated in Jilin Changbai and Yunnan, most of the other deposits are grade 3-4 soil, because of the high content of impurities, can not be directly used in deep processing.

16. Rice husk: (blackened, crushed and called rice chaff ash) can increase heat absorption and make the ground temperature. The rising water temperature promotes plant growth and reduces cold damage. Loose and porous, good ventilation, increase the supply of oxygen to the root. Promote plant absorption, improve acid soil, reduce fertilizer loss and emission to prevent invasion of species such as molluscs.

17. Water moss: pure natural products, clean materials, no germs, can reduce the occurrence of diseases and insect pests, good water retention and drainage performance, with excellent ventilation performance, not easy to decay, can be used for a long time, and do not need to update all materials in the basin change. can be used alone or mixed with other substrates, easy to cultivate.

18. Volcanic rock: volcanic rock (basalt) is a porous stone formed after volcanic eruption, which is very precious. Yanlei volcanic rocks in Shanghai are rich in sodium, magnesium, aluminum, silicon, calcium, manganese, iron, phosphorus, nickel, cobalt and other minerals. It can promote plant growth, increase soil permeability and prevent rotting roots.

19. Fairy soil: because the fairy soil contains a variety of trace elements, coupled with its own cohesion, not loose, good water retention, air permeability, no consolidation, no bacteria, no disorderly roots, more sprouting, no fertilization within two years, 3-5 years can be slightly applied thin fertilizer. Especially suitable for beginners to grow orchids, you don't have to worry about how to fertilize orchids, as long as you master the watering method.

20. Rotten leaf soil: first, light and loose, good permeability, and strong ability to retain water and fertilizer; second, porous, long-term application is not hardened, easy to be absorbed by plants. Mixed with other soils, it can improve soil and improve soil fertility; third, it is rich in organic matter, humic acid and a small amount of vitamins, auxins and trace elements, which can promote the growth and development of plants; fourth, the high temperature in decomposition and fermentation can kill bacteria, insect eggs and weed seeds, and reduce the harm of diseases, insects and weeds.

21. Orchid stone: a general term for porous stone materials used to cultivate orchids, which is a positive medium. Some are formed naturally and some are man-made. Including pond foundation stone, pumice stone, phytolith, volcanic rock and so on. Lanshi is widely used in family Lanhui cultivation. It is generally porous, and the voids are visible to the naked eye, so it has strong water absorption and water retention; and because it is granular and there is a large gap between particles when stacked, it has quite good air permeability, and the cultivated orchids are not easy to rot, clean and beautiful. it is an ideal medium for planting orchids.

twenty-two。 Cinder: cinder, a kind of industrial solid waste, also known as slag from coal-fired power plants, industrial and civil boilers and other equipment. The main components are silicon dioxide, alumina, iron oxide, calcium oxide, magnesium oxide and so on. It can be used for succulent plant cultivation. Because of the various chemical elements in the cinder, it can be soaked for a short time before use to reduce the content of chemical elements.

23. Pine scale: a substrate produced by fermentation of dry bark on the surface of trees such as pines. Water conservation, ventilation, not suitable for insects, is a better Peilan matrix, can also be used as plant paving and other art forms.

24. Eggshell: egg white yolk removed, washed, smashed after a product, more common. Can be used as the substrate for the cultivation of succulent plants, breathable and moisture-proof, not too much, easy to agglomerate.

25. Zeolite: the general chemical formula of zeolite is: AmBpO2p?nH2O, the structural formula is A (AlO2) Q) [(AlO2) x (SiO2) y] n (H2O), where An is Ca, Na, K, Ba, Sr and other cations, B is Al and Si,q are cationic valences, m is the number of cations, n is the number of water molecules, x is the number of Al atoms, y is the number of Si atoms, and (y) is usually between 1 and 5.

Introduction to woody flowers in the classification of flowers

Woody flowers. The stems of this kind of flowers and trees are Lignified, relatively hard, and are generally taller than herbs. According to its morphological characteristics, it can be divided into three types: trees, shrubs and vines (or vines).

Arbor flowers. The tree is tall, with obvious trunk, upright, exuberant growth and luxuriant branches. This kind of flowers and trees can be divided into evergreen trees and deciduous trees according to their evergreen or deciduous growth habits. Evergreen trees such as Magnolia, Magnolia, Osmanthus fragrans, Magnolia mandshurica, etc.; deciduous trees, such as Magnolia, plum blossom, turquoise blossom, Xifu begonia flower and so on.

Shrubs and flowers. No obvious main pole, low tree shape, often branching from the root neck, can also be divided into evergreen shrubs and deciduous shrubs. The former such as rhododendron, camellia, mast flower, Milan, Fusang, oleander, jasmine, etc.; the latter, such as rose, rose, primrose, wax plum, pomegranate, etc.

Vines and flowers. The branches are long and thin, can not stand upright, often climb or grow around other things, such as evergreen ivy, Fufang vine, honeysuckle, etc.; deciduous flowers, wisteria, wall-climbing tiger and so on.

The other is classified according to the ecological conditions of flowers. That is, it is classified according to the flowers' different requirements for temperature, sunlight and water. For example, according to the requirements for temperature, flowers can be divided into cold-resistant flowers, semi-cold-resistant flowers and non-cold-resistant flowers; according to the requirements for sunlight, they can be divided into sun-loving flowers, yin-loving flowers and semi-yin-semi-yang flowers; according to the requirements for moisture, it can be divided into aquatic flowers, wet flowers, xerophytic flowers and mesophytic flowers.

The other is classified according to the ornamental use of flowers, which can be divided into five categories: flowering flowers, foliage flowers, fruit flowers, stem flowers and aromatic flowers.

Herbaceous flowers

(1) Annual flowers: complete their life history in the same year, usually sowing in spring, blossom and bear fruit in summer and autumn, also known as spring sowing flowers in production. Such as: thousand-day red, Fu Lukao, Scutellaria barbata, impatiens, marigold and so on.

(2) biennial flowers: flowers that complete their life history every year, usually sown in autumn, only stay in vegetative growth in that year, accept vernalization in the process of low temperature in winter, and can blossom and bear fruit and die in the next spring and summer, so they are also called autumn sowing flowers. Such as: calendula, daisies, violets, pansy and so on.

(3) perennial herbaceous flowers: usually blossom and bear fruit many times, with a life span of more than two years, which can be divided into two types according to the shape of the underground part:

① perennial flowers: the root persists through the winter and continues to germinate and grow in the next spring. The root shape is normal and no metamorphosis occurs. Such as: chrysanthemum, day lily, peony, hairpin, four seasons begonia, lotus peony, carnation and so on.

② bulb flowers: the underground part has hypertrophic and nutrient-rich abnormal stems or abnormal roots, mainly

A corms: underground stems are shortened and enlarged, wrapped by several layers of membranous bark, the lower part of the bulb forms a ring mark, that is, a shortened node, and there are hypertrophic terminal buds at the top, budding to form the aboveground part, and propagating with hypertrophic corms or bulbs in spring or autumn. Such as: gladiolus, freesia, saffron.

B bulbs: bulb discs with shortened or discoid underground stems. Such as daffodils, lilies, hyacinths, tulips, Zhu Dinghong and so on.

C rhizome: root-like underground stem, succulent hypertrophy, branched, with obvious nodes and very short internodes, each node with lateral buds, located in the axils of the degenerated scale leaves on the nodes. Such as: canna, ginger flowers, lily of the valley.

D tubers: short and hypertrophic irregular tuberous rhizome nodes are very short, with budding eyes on the nodes, can branch leaves, and are usually propagated by tubers. Such as calla lily, big rock tree, colored leaf taro, cyclamen and so on.

E-root type: the root expands into a tuber root, and there is a germination point at the top of the tuber root, from which new shoots germinate. Such as dahlia, buttercup and so on.

(4) Aquatic flowers: they grow in water all the year round, and most of them are herbaceous flowers with rhizomes and persistent roots. According to the posture of their growth in water, they can be divided into four categories:

Standing water type: stems, leaves and flowers stand upright above the water surface, and the roots are stuck in the mud. Such as lotus, water calamus and so on.

Floating type: stems, leaves and flowers float on the surface of the water, and the roots are stuck in the mud. Such as water lilies, king lotus and so on.

Submerged type: the stems and leaves of the plant are sunk in the water, and the roots are stuck in the mud. Such as goldfish algae, fish grass, bitter grass and so on.

Floating type: the root system does not enter the soil, the whole plant floats and moves on the surface of the water.

(5) cactus and succulent plants: stems and leaves have a variety of metamorphosis, well-developed water storage tissue, thick, fleshy and pulpy, some species of leaves degenerated into needling, 'thorn seat' born in the abnormal stem. Thorns, bulbs, stem nodes, flowers have a strange posture, colorful flowers, quite interesting. Common are: cactus, cactus, Ling arrow lotus, crab melon orchid, epiphyllum, stone lotus, Yushu and so on.

(6) Lawn and ground cover plants:

① Lawn: refers to the low grass covering the ground in the garden, mostly perennial herbs. Such as grass family, cyperaceae, leguminous, etc., zoysia, ryegrass, wild grass, bermudagrass, bluegrass, cuttings, carpet grass, fescue, etc.

2 ground cover plants: general term for low plant groups that can cover the ground, mainly perennial herbs, including foliage, small shrubs and rattan trees.

Why do families grow flowers, what are the benefits of raising flowers, and how to raise flowers?

1. What are the benefits of growing flowers?

Flowers with its brilliant style, the natural decoration is particularly beautiful, giving people the enjoyment of the United States. Flower cultivation can enrich and adjust people's cultural life, add fun, edify temperament, improve health, and increase scientific knowledge and improve cultural and artistic literacy. Flower cultivation can beautify the motherland, protect and improve, purify the air, so that people can work and study in a beautiful environment, and live a better life. Flowering, not only for viewing, but also has many important economic value. Flowers are an important part of Chinese herbal medicine, honeysuckle, chrysanthemum, Chinese plum, hibiscus, rhododendron, rose, lotus and so on are commonly used Chinese herbal medicine. Fragrant flowers are widely used in food and light industry. For example, osmanthus can be used as food spice and wine, jasmine, white peony, generation, pearl orchid and other feasible smoked tea leaves, chrysanthemum can be used for high-grade food and dishes. White orchid, jasmine, rose, wax plum, narcissus and so on can extract essence. Raising flowers can also be exchanged for foreign exchange and accumulate funds. For example, rose oil, a high-grade essence extracted from roses, is known as "liquid gold" on the international market, and its value is more expensive than gold.

2 What are the types of flowers?

China is known as "the mother of gardens in the world". Flower resources are rich and varied. In order to facilitate cultivation, management and utilization, it is necessary to understand the classification knowledge of flowers. Because the classification basis is different. Therefore, the classification methods vary. According to the morphological characteristics of flowers, flowers are usually divided into two categories: herbaceous flowers and woody flowers. The soft stems are herbaceous flowers, and the hard stems are woody flowers. According to flower growth habits and morphological characteristics classification, generally can be divided into herbaceous flowers, woody flowers, succulent flowers and aquatic flowers. Herbal flowers according to their growth and development cycle, etc., can be divided into annual, biennial grass flowers, perennial flowers, bulbous flowers and lawn plants. Woody flowers according to its trunk height and crown size, etc., can be divided into trees, shrubs and vine flowers. Fleshy flowers, with fleshy stems and leaves, rich in water stored in the body, some leaves degenerate into needles or feathers,

It is unique in shape, so it has its own class in horticultural cultivation.

Aquatic flowers, year-round growth in the water, swamp zone, most of them belong to perennial plants, according to the ornamental part classification, flowers can be divided into, ornamental class (mainly ornamental flower color and flower shape, such as chrysanthemum, rose, etc.), leaf type (mainly ornamental leaf color and leaf shape, such as variable leaf wood, mosaic taro, etc.), fruit type (mainly ornamental fruit, such as kumquat, etc.), stem type (mainly ornamental branch stem, such as bachelor tree, mountain shadow boxing, etc.) and bud type (mainly ornamental bud, such as silver willow). According to the purpose, flowers can be divided into cut flowers (such as carnation, calla lily, etc.), indoor flowers (such as clivia, turtleback bamboo, etc.), garden flowers (such as rose, chrysanthemum, etc.), medicinal flowers (such as peony, honeysuckle, etc.), spice flowers (such as white peony, jasmine, rose, etc.) and edible flowers (lily, day lily, pomegranate). In addition, according to the climatic conditions of the origin of flowers, according to the natural distribution, flowers are divided into tropical flowers, subtropical flowers, warm temperate flowers, temperate flowers, sub-frigid flowers, alpine flowers, etc. This classification reflects the habits of various flowers and the conditions for their growth and development that need to be met during cultivation.

3 What are flower bulbs?

Bulbous flower is to point to underground bine or root occurrence metamorphosis, show globose or the perennial herbaceous flower of shape.

According to the morphological structure of its underground stem or root, it can be roughly divided into five categories:

Bulbs: underground stems were scale-like. Those with a papery outer skin are called scales, such as tulips, narcissus, amaryllis, etc.; those without an outer skin on the outside of the scales are called skinless bulbs, such as lilies.

Bulb class: underground stem was spherical or oblate, outside the leather system skin, such as gladiolus, snow orchid and so on.

Rhizomes: underground stem hypertrophy was root-like, there are obvious nodes above, new buds born at the top of the branches, such as canna, ginger flowers, lotus, water lily, hairpin and so on.

Tubers: underground stems were irregular block or strip, such as calla, cyclamen, pittosporum, tuberose, etc.

Root tuber class: underground taproot hypertrophy was massive, root system from the end of the root tuber born, such as dahlia and so on.

4. What is the relationship between temperature and flower cultivation? Temperature is an important condition for the survival of all kinds of flowers. No matter how suitable other environmental conditions are, flowers cannot survive without suitable temperature conditions. The growth and development of each flower has its optimum temperature, maximum temperature and minimum temperature. According to the origin temperature of flowers, flowers can be divided into high temperature, medium temperature and low temperature.

(1) High temperature category: such as Milan, poinsettia, melon, pittosporum, fuchsia, etc. In North China, the lowest temperature in winter should be kept above 12 ℃.

(2) Moderate temperature: such as white peony, jasmine, hibiscus, geranium, etc., the winter room temperature shall not be lower than 5 ℃;

(3) Low temperature: such as oleander, osmanthus, kumquat, generation, cycad, etc., winter room temperature is not lower than 0 degrees can be. If the temperature is too high or too low, the normal physiological activities of flowers will be destroyed, the growth will stop, and the whole plant will die when it is serious.

5. What effect does light have on flower growth? Light is the energy source for flower plants to produce nutrients. Without light, photosynthesis cannot be carried out, and the growth and development of flowers will be seriously affected. Most plants can flourish only in sufficient light. Different types of flowers have different requirements for light. Flower proverb cloud: "Yin camellia, Yang peony, half Yin half Yang four seasons orchid." According to the different requirements of flowers for light intensity, flowers can be divided into positive flowers, neutral flowers and negative flowers.

(1) Positive flowers: Most flowers and fruits belong to positive flowers, such as magnolia, rose, pomegranate, plum blossom, crape myrtle, citrus, etc. There are also a few positive flowers in the flowers of the leaf category, such as cycas, palms, and variegated leaves. Most aquatic flowers, cacti and succulents are also male flowers. All male flowers like strong light, but do not bear shade. If the sun is insufficient, it is easy to cause excessive branches and leaves, soft and weak tissues, pale yellow leaves, difficult flowering or poor flowering, and easy to suffer from diseases and insect pests;

(2) Negative flowers: grow well under shaded environmental conditions, such as asparagus, camellia, rhododendron, hairpin, green radish, evergreen, ivy, pittosporum, turtle, begonia, etc. If exposed to strong light for a long time, the branches and leaves will wither, growth will stagnate, and serious ones will even die;

(3) Neutral flowers: grow well under sunny conditions, but when the summer light intensity is large, there is no principle of shade, such as osmanthus, jasmine, white peony, hydrangea, etc. To sum up, all kinds of flowers have different requirements for light, and even the same kind of flowers have different requirements for light at different stages of growth and development. When seedlings need light, they can gradually increase, but positive chrysanthemum requires flower buds to form under short day conditions.

6. What effect does light have on flower bud differentiation? The purpose of people cultivating flowers is to make them bloom more flowers, and light is the most effective external factor to promote flower bud formation. On the same flower, the branches that fully receive light have more flower buds; the branches that receive insufficient light have fewer flower buds. When summer sunny days, flowers receive sufficient light, flowers in the coming year on more. Generally speaking, flower plants can carry out photosynthesis at temperatures of 10--35℃, with the optimal temperature of 20--28℃. According to the requirements of the flower for the length of light, flowers can be divided into three categories:

(1) Long-day flowers: Generally, the daily sunshine time needs more than 12 hours to form flower buds, which is called long-day flowers. Many flowers bloom in spring and summer, mostly belong to long-day flowers, such as iris, aster, impatiens and so on;

(2) Short-day flowers: Flowers that have less than 12 hours of sunshine per day to form flower buds are called short-day flowers. Poinsettia and chrysanthemum are typical short-day flowers. They can only grow under long sunshine in summer and cannot differentiate flower buds. After autumn, when the light is reduced to 10--11 hours, flower bud differentiation begins.

(3) Medium sunshine flowers: flowers whose flower bud formation is not strict with the length of daytime sunshine are called medium sunshine flowers. Such as calla lily, carnation, zinnia, rose, hibiscus, etc., they do not have obvious response to the length of light time, as long as the temperature is right, they can bloom all year round.
