What is the growth process of sunflowers?

The growth process of sunflower includes seedling stage, budding stage, flowering stage, and maturity stage.

1. Seedling stage:

From the emergence of seedlings to the emergence of buds, it is called the seedling stage. Generally, it takes 35-50 days, and 28-35 days for summer sowing. This period is the stage of leaf and flower primordium formation and floret differentiation.

At this stage, the growth of the aboveground part is stunted, and the root system of the underground part grows rapidly, and a strong root system is formed soon, which is the stage with the strongest drought resistance of sunflower.

2. Current bud period:

A stellate body with a diameter of 1 cm appears on the top of the sunflower, commonly known as the bud. It generally takes about 20 days from budding to flowering, which is the period of vegetative growth and reproductive growth, and it is also the most vigorous stage in life. During this period, sunflowers need the most fertilizer and water, accounting for about 40%-50% of the total fertilizer and water requirements.

If the demand for water and fertilizer cannot be met in time during this period, the yield will be seriously affected.

3. Flowering period:

In the field, 75% of the plants have tongue-shaped flowers open, that is, they enter the flowering stage. It usually takes 6-9 days for a flower disc to bloom from the tongue to the tubular flower. From the second to the fifth day is the inflorescence.

The peak flowering period. The number of flowers blooming on these 4 days accounts for about 75% of the number of flowers. The flowers mostly bloom at 4-6 a.m. and are pollinated and fertilized the next morning. Unfertilized shoots can remain unwilted for 7-10 days.

4. Maturity period:

From flowering to maturity, 25-55 days for spring sowing and 25-40 days for summer sowing, there are differences among different varieties, and about 15 days of flowering and pollination shield is the stage of seed formation. The weather should be clear, the temperature difference between the day and liquid should be large, and the soil moisture should be suitable.

Sunflowers generally bloom in May and end in November.

Sunflower cultivation methods and precautions.

1. Watering. When cultivating sunflowers, you should water them frequently. It has a high requirement for water and is indispensable during growth.

Usually it is watered every day in the summer, usually every other day, but it is best to avoid stagnant water. If it is rainy weather, it is necessary to drain the water in time to avoid root rot in the stagnant water.

2. Illumination. Sunflowers naturally love the sun. Usually put it in a sunny place, bask in the sun, and it is best to be exposed to direct light, so that the light will be better flowering, growing, and flourishing.

If you don't get sunlight for a long time, the flowering period will end early, or you may not even bloom.

3. Fertilization. Sunflower likes fertilizer, and must be fertilized frequently during the peak growing season, usually once every two weeks to apply Trim water-soluble fertilizer, and the nutrients are enough for the sunflower to grow vigorously. Pay attention to the concentration when fertilizing, and dilute it before watering, so that it can be better and faster absorbed.

If the fertilizer concentration is high, it is easy to burn the roots.

Fourth, soil. Sunflower has a certain resistance to barrenness, and the general garden soil can ensure the normal growth demand. However, if you want it to grow more vigorously, it is recommended to use soil with good drainage performance and more fertile, and the garden soil can be mixed with river sand.

as well as basal fertilizers, which are helpful for growth.

5. Precautions.

When raising sunflowers, pay attention to put them in a ventilated place, if the environment provided is too hot and humid, it is easy to be infected with pests and diseases. Be sure to spray as soon as possible after spotting, otherwise the plant may die.

<> flowering period: 5-11 months.

The sunflower flowering period is at least 7 months, the hotter the place, the longer the flowering period, it is not only a hard-working flowering machine, but also a cheap flower that is super easy to raise, a branch can live in the soil, and some varieties can also reproduce a large area by sowing every year!

Sunflower belongs to the purslane family succulent herbaceous plants, the natural flowering period is 5-10 months, although it is a perennial herbaceous plant, but because it is not tolerant to severe cold, it needs to be replaced by raising roots or sowing seeds every spring, and the amount of flowering will burst the pot. It can also be grafted with golden branches and jade leaves, old piles of roots, leaf fairies, etc., but it requires a certain gardening foundation to be successful, and interested flower friends can also try it.

Sunflowers generally bloom in May and can last until before frost.

The exact time when the sunflower blooms depends on the mode of reproduction, the local climatic conditions, and whether the individual breeds in a sunny environment. Sunflowers are propagated by sowing, which is generally sown in March and April, and can only bloom in May and June, while by cuttings and propagation by root seedlings, they can bloom in May. It is mid to late March, it is the time when a large number of sunflower seeds and root seedlings are on the market, and friends who want to raise sunflowers can take advantage of the spring to cultivate some, and they can harvest a sea of flowers after more than a month.

Sunflowers, also known as "noon flowers", are sun-loving plants

Although the sunflower flowering period is super long, the flowering period of a single flower is only one day, and it blooms at noon and closes in the evening, it likes the sun very much, and the stronger the light, the brighter it blooms, so it also has the title of noon flower. At the same time, the sunflower can tolerate drought and barrenness, the soil is not picky, the general garden soil, sandy loam soil, humus soil, cheap nutrient soil, etc. can be planted, both potted and ground planted, in addition to being used for balcony potted plants and courtyard ground planting, now it has also been widely used in flower bed decoration and urban greening, blooming flowers into pieces, pleasing to the eye!

Although sunflower is not tolerant to severe cold, most varieties can be kept for spring sowing, or they can be put away in a warm room during the cold season to continue to raise roots, and then pruned for cuttings after new branches are replanted in spring. Cheap, easy to raise, long flowering period, sowing flowers and plants in spring, sunflower is indeed the first choice!

If you look at it from a year, it generally blooms from summer to autumn, because it is not good for sunflowers to be too cold in winter, so generally in spring when the temperature rises and you can start to sow seeds, and when you grow up, it will be almost summer. Then it blooms until autumn, and when the weather is very cold, even after winter, it will slowly wither.

If it is from a day, he generally blooms at noon, so he calls it noon flower.

Sunflowers bloom in June to September every year, the flowers have the characteristics of flowering to the sun, generally in the morning and evening and cloudy days when the flowers will be closed, the better the flowering when the sun is strong, when breeding sunflowers, choose humus with high trace element content, and sterilize the potting soil before planting to reduce bacterial breeding.

In general, if the sun flower is single, it will start to bloom at about 9 o'clock in the morning, and the flowers will be closed around 5-6 o'clock in the afternoon, and other flowers will bloom the next day.

2. Sunflower aliases: large-flowered purslane, broad-leaved half-branched lotus, sunflower, half-day flower, pig suckling flower. Purslane peony that is resistant to high temperatures and drought.

Sunflowers generally bloom in summer.

The sunflower situation you asked, under normal circumstances, it should be sown in spring, basically in April and May, it should be able to bloom, there is no problem.

The sunflower blooms for at least 7 months, the hotter the place, the longer the flowering period, it is not only a hard-working flower, but also a super easy flower, a branch can live in the soil.

The flowering of the sunflower is generally in the month, this flower usually blooms best at noon, and it is basically not visible in the morning and evening and when it is cloudy, so it is also called the sunflower. Its flowers bloom for a long time, until September and November.

Cultivation methods and precautions.

1. Illumination. Sunflower is a strong positive flower, sun-loving, when maintaining at home, be sure to give it enough light, even if it is summer exposure does not need to be shaded, lack of light, it will affect the amount of sunflower and flower size.

2. Temperature. The most suitable growth temperature for sunflowers is 26-29, not afraid of high temperatures and low temperatures, the lower the temperature, the slower the growth rate of sunflowers, and when the temperature is lower than 15, sunflowers will stop growing.

3. Watering. Sunflowers like to grow in dry soil, not afraid of drought or waterlogging, too much watering will make the root system of sunflowers rot. Therefore, during the growth period of the plant, it must be given water in strict accordance with the watering principle of "seeing dry and wet".

Fourth, fertilization. The demand for fertilizer and water for sunflower is not high, only need to apply a Bika granule compound fertilizer during the plant growth period to promote the growth of sunflower, and before the plant flowering, apply a phosphorus and potassium fertilizer to promote the flowering of sunflower.

Sunflower is the month that blooms.

Raise sunflowers, master these 3 "conditions", and the flowers are numerous and bright.

The temperature is right, it blooms in all seasons, and it can be raised indoors in winter.

The growth process of sunflower includes seedling stage, budding stage, flowering period, maturity period, the growth cycle of sunflower is about 2 months, from the seed pot sowing to the sunflower bud, usually to wait for 60 days, sowing in spring, waiting until summer to flower, the higher the average temperature, the more beneficial it is to its growth, if there is no time to sow in spring, it can also be carried out in autumn.

There are no strict requirements for the planting time of sunflowers, it is best to plant them in the warm spring, because the spring climate is mild, suitable for plant growth, and the survival rate is high, and if there is no time, it can also be planted in autumn.

The growth cycle of the sunflower is about 2 months, from the seed is potted and sown to the sunflower grows buds, it usually takes 60 days to wait, sowing in the spring, and waiting until the summer to bloom, the higher the average temperature, the more beneficial it is for its growth.

Sunflower growth process.

1. Seedling stage:Sow sunflower seeds in spring, wait for a few days, sunflower will grow young shoots, from the beginning of germination to sunflower buds are belong to the seedling stage, the seedling period lasts about 30 days, during this period, sunflower will continue to grow, rhizomes continue to grow taller.

2. Current bud period:After the seedling stage, when the top of the sunflower grows a star until the sunflower blooms, it belongs to the budding period of the sunflower, this period lasts about 20 days, during this period, the sunflower will work hard to absorb nutrients, grow more vigorously, and its flowers and leaves will always be in a state of growth.

3. Flowering period:During the flowering period, three-quarters of the flowers on the sunflower and the front of the flower begin to bloom, and the flowering period is considered when the flowers are fully opened, which lasts about 6-9 days, but it should be noted that the flowering period will be shortened if pollinated.

4. Maturity period:The period from the end of the sunflower to the full maturity of the sunflower seeds belongs to the maturity period of the sunflower, which will last about 25-55 days, and under the condition of the right amount of watering, temperature and light, the sunflower seeds will be fully mature after about 1 month.

How to plant sunflowers.

1. Prepare the soil:Sunflower growth needs to use loose and fertile, good air permeability and drainage soil, you can use humus, garden soil and sand river soil, you can add a small amount of organic fertilizer, increase soil organic nutrients.

2. Sowing and planting:Choose well-grown, plump seeds, spread them evenly in the soil, keep the temperature above 20 degrees, water them lightly, and cover them with a thin layer of soil, so that they can take root quickly.

3. Post-seed management:After the sunflower is planted, it needs to be carefully managed, the temperature is stable in spring and autumn, the temperature is high in summer, placed in a cool position to breed, the temperature in winter is low, not less than 5 degrees, it can be placed in a sunny position indoors, if there are pests and diseases, insecticides or carbendazim can be used.

Strong heat tolerance: Sunflowers can grow and develop normally even in the hot summer months. Drought-resistant:

Wild plants do not die without rain for several months. Adaptable: Extremely resistant to barrenness, can grow in general soil.

Blooming at the sun: The sun blooms when it sees sunlight during the flowering period and closes in the morning, evening and cloudy days.

1. Strong heat resistance

Sunflowers are heat-tolerant and can grow and develop normally even in the hot summer, but in order to promote the large and colorful flowers of the plants, it is best to take cooling measures in the hot season, such as spraying water mist and moving to an air-conditioned room, etc., and be careful not to put them in the vents.

2. Strong drought resistance

Sunflower has good drought resistance during the growth process, it is generally wild on the slopes, between the fields, even if it does not rain for a few months will not die, when family farming, it needs to be watered every 3-5 days, and each watering should be watered thoroughly to keep the soil moist.

3. Strong adaptability

Sunflower is very adaptable to the environment, it is extremely resistant to barrenness, can grow in the general soil, especially for well-drained sandy loam, pot planting, can be used humus, garden soil, river sand mixed with soil, to maintain good permeability.

4. See the sun and bloom

When the sunflower is in the flowering period, it will bloom as long as it sees the sun, and it will close in the morning, evening and cloudy days, so it is called the noon flower, the sunflower, the flower is solitary or several clusters at the end of the branch, the petals are obovate, purple, red or yellowish-white, etc.

The change process of sunflower in the seedling stage, the plant will grow buds and young buds, the leaves and branches have just been differentiated, in the budding stage, the plant branches grow flower buds, the branches grow vigorously, in the flowering period, the petals of the plant will change from tongue-shaped, into tubular shape, the flower color is purple, yellow, white, orange, etc., in the mature period, the flowers will be fully bloomed.

In the seedling stage of sunflowers, the plant has just grown buds and young shoots. At this time, the leaves and branches of Sunflower are in the process of differentiation, and the root growth rate of the plant is relatively rapid, but the overall growth trend is relatively slow, and a small amount of basic fertilizer for decomposition and fermentation needs to be applied to promote the growth of the plant.

In the budding stage of sunflower, flower buds will grow on the branches of the plant, the length is 5 8 cm, the width is 1 cm, the growth of the plant branches is more vigorous at this time, the branches in the dense place need to be thinned and the main trunk is topped to promote the growth and development of the side branches of the plant.

During the flowering period of the sunflower, the inflorescence on the flower disc will slowly change from tongue-shaped petals to tubular petals, with purple, yellow, white, orange, etc., at this time, it is necessary to apply an appropriate amount of nitrogen and phosphorus fertilizer, and apply urea every half a month to provide sufficient nutrients for the growth of the plant.

In the mature period of sunflowers, the flowers will be fully bloomed, and it is necessary to prune the branches and leaves of wilted, drooping, overlapping, diseases and pests on the plant in time, and apply phosphorus and potassium compound fertilizer, which is conducive to the flowering of the plant more lush, the flower color is more gorgeous, and the soil is loosened regularly, the soil viscosity is reduced, and the root system of the plant is conducive to better absorption of nutrients.
