Can sunflowers be planted in the sand Can sunflowers be grown in sand?

Yes, sand grows more easily than soil.

Flower name: Sunflower.

Morphological characteristics: It is an annual succulent herb. The height of the plant is 10-15cm. The petals are bright in color, with white, dark yellow, red, and purple colors. There are many varieties of horticulture, including single petal, semi-double petal, and double petal.

Growth habit: likes warm, sunny and dry environment, extremely barren and thin, the general soil can adapt, can self-sow and reproduce. Seeing the sun blooming, the morning, evening, and cloudy days are closed, so there is the name of the sun flower and the noon flower. Flowering period 6 and this is missing in July.

Cultivation and breeding: Sunflower seeds are very small. Seedlings are often sown in seedling trays, lightly covered with fine-grained vermiculite, or only slightly compacted after sowing to ensure sufficient moisture.

The germination temperature is 21 24, about 7 10 days to emerge, the seedlings are extremely weak, so if the temperature is maintained, the seedlings grow quickly, and they can form thicker, fleshy branches and leaves. At this time, the seedlings can be directly potted, using pots with a diameter of about 10 cm, planting 2 5 plants per pot, with high survival rate and rapid growth.

Cuttings method. Smooth the level of the culture soil in the container, insert the cut sunflower shoots into the hole poked by bamboo chopsticks, and go deep into the culture soil no more than 2 cm. In order to make the potted flowers form and plump as soon as possible, depending on the size of the pot, as long as the spacing of 2 cm can be maintained, multiple cuttings can be taken (when the seedlings are crowded, they can be planted in other pots).

Then pour plenty of water. New cuttings can be shaded, or not shaded, as long as a certain humidity is maintained, generally 10 to 15 days can survive, into normal maintenance.

Usual maintenance. Sunflowers are very seldom pests and diseases. Usually maintain a certain limb search humidity, and apply one-thousandth of potassium dihydrogen phosphate once a half month, which can achieve the purpose of large and colorful flowers and continuous blooming. If there are multiple varieties of cuttings in one pot, all kinds of flowers bloom in one pot, and the appreciation value is higher.

Seedlings overwintered. Every year after the frost falls (in Shanghai), the double-petaled sunflower is moved indoors to shine into the sun. After winter, put it on the inside of the glass window and let the potting soil dry a little, so that it can safely overwinter.

After Qingming in the following year, you can put the flower pot in Lizhou outside the window, in case of cold snap, you need to go into the window to maintain.

Sunflower planting should go through a series of processes such as preparing potting soil, sowing seeds, raising seedlings, thinning seedlings, transplanting seedlings, picking heads, watering, and harvesting seeds.

Prepare potting soil. Although "barren resistance" is one of the characteristics of sunflowers, its growth does not care about the quality of the soil, but as a flower keeper always expects flowers to grow strong, leafy, and colorful, so it is better to prepare a loose, breathable, and fertile soil as much as possible.

Sunflowers can be planted with sand, sunflowers disturb the base is a slow touch to plant a better kind of flowers, for the planting soil requirements are not high, with sand can also be planted, as long as the nutrients and water keep up with the can also grow very well.

The best suitable planting time for sunflower is spring, choose loose and breathable, well-drained, humus-rich soil, sprinkle the seeds on the soil after germination treatment, water to keep the soil moist, and transplant it to germinate, and apply potassium dihydrogen phosphate once every half month.

When cultivated in hanging bowls or potted plants, the flowers will be large and beautiful if there is still sufficient sunlight during the flowering period, otherwise not only the flowers will be small and the number will be small, but the plants will also grow. After the flower, the fruit is very similar to the bud, after the fruit is ripe, the peel turns dark brown, at this time it can be gently picked by hand, and the next spring is sown after drying, and the plant can be slightly pruned, cut off the flowering branches, promote the growth of good momentum, and conducive to flowering. The pruned branches can be used for cuttings.

The flower language of the sunflower

1. Longing for light.

Sunflower has the meaning of yearning for light, sunflower can not be maintained in a dark and lightless environment, otherwise the plant will be difficult to bloom, so the sunflower is very yearning for light and warmth, can express the yearning for life and dreams.

2. Silent love.

The sunflower represents silent love, the sunflower is gorgeous, the flower is always blooming upward, which can bring positive energy to people, and the sunflower is given to a friend, indicating that a friend can bring light and positive energy to himself.

3. Not afraid of difficulties.

The flower language of the sunflower is not afraid of difficulties, the sunflower has good cold tolerance and drought tolerance, whether it is in a cold environment, or in the dry soil, as long as the light is sufficient, it can bloom beautiful flowers, the sunflower is given to friends who encounter difficulties, which can express encouragement to friends.

The sunflower is also known as the half-branch lotus, which can only bloom when it encounters sunlight, and the flowers close when there is no sun. Due to its strong reproductive ability, it is relatively easy to maintain, but it is not easy to want the sunflower to burst the pot, so let's take a look at how to cultivate the sunflower of the pot.

1. Cultivation of sunflowers.

There are two main ways to grow sunflowers: cuttings and seeding. The success rate of both methods is relatively high, so it is understandable which method to choose for planting, and the following mainly introduces the use of sowing propagation to cultivate sunflowers.

For sunflowers, in addition to being unsuitable for propagation in winter, sowing propagation can be carried out in spring, summer and autumn. If the seeds are sown and propagated in the spring, it should be noted that the ambient temperature of the seeds before germination needs to be maintained at 20-25 degrees, so this temperature may not be reached in the early spring, and the germination of seeds should be carried out in the greenhouse. The depth of seed sowing is best about 3 cm from the soil surface, and it can germinate after 10-15 days after the seed is sown, and after the plant grows a few true leaves, the first top dressing measures will be carried out, about 3 weeks, and the seedlings planted in pots or open fields can be planted separately.

Second, the daily management of sunflowers.

1.Illumination. The name of the plant shows how important light is to the sunflower.

Light conditions are the most important factor affecting the growth of sunflowers, no matter in which growth period, its growth is inseparable from light; If it is cultivated in a shady place, it will not only fail to grow and bloom normally, but may also cause it to die. Therefore, in daily management, the sunflower should be planted in a sunny place, and if it encounters rainy weather, it should be moved to a place with bright light indoors for growth.

2.Soil. One of the reasons why sunflowers are easier to grow is that there is no requirement for soil, generally speaking, choose the sandy soil commonly used in flowers, if the soil configuration is more balanced and rich, you can add an appropriate amount of river sand and garden soil to improve the drainage of the soil.

In addition, it is also a good idea to add a sufficient amount of basal fertilizer to ensure that sufficient nutrients are given before the plant is fully differentiated.

3.Watering. The need for water in the sunflower is an ordinary level among many plants, and if it is watered daily, watering twice a week is a more suitable choice; In summer, when the temperature is high, it can be increased to 3 times a week, or even once every other day.

It should be noted that the watering process should not be too rushed, and it should be applied slowly from the periphery of the plant at an even rate, which can well avoid water accumulation in the soil.

4.Disease. Because the sunflower has good disease resistance, it is less likely to encounter diseases and insects in the process of plant cultivation.

However, before the sunflower grows true leaves and before the flowering period comes, it is best to take sufficient protective measures and buy corresponding insecticides in the market to spray, such as chlorothalonil or flower protector solution, to ensure that the flowering of the plant can go smoothly.

1. Preparation of soil: When planting sunflowers, it is necessary to use river sand, garden soil and organic fertilizer to prepare the base soil. 2. Planting method:

Sunflower seeds are mixed with fine sand and sprinkled on the surface of the soil. 3. Scientific watering: Sunflowers like water and need to be watered 1-2 times a week.

4. Top dressing fertilizer: Sun peanuts should be topdressed once a month for a long time.

1. Prepare soil

Sunflower is suitable for growing in sandy loam soil rich in organic matter, when planting sunflower, it is necessary to use river sand, garden soil and vermiculite in a ratio of 1:3:1 to mix and prepare a cultivation substrate, and then apply well-rotted organic fertilizer to the soil to improve the fertility of the soil and promote the vigorous growth of sunflower.

2. Planting method:

The seeds of sunflower are small, and when planting sunflower, you need to mix the seeds with fine sand in a ratio of 1:4, and then sprinkle them evenly on the surface of the soil, and then put the pot into a bucket to supply water by soaking at the bottom to avoid being washed away when watering the sunflower seeds.

3. Scientific watering

Sunflower is a water-loving plant, it needs sufficient water during the growth process, when cultivating sunflower, it needs to be watered 1-2 times a week in spring and autumn to promote the vigorous growth of the plant, and in summer it needs to be watered once a day, and it is necessary to spray water mist around the sunflower regularly to improve air humidity.

4. Top dressing fertilizer

When cultivating sunflowers, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer once a month in the peak season of plant growth to provide the nutrients needed for flowering, and during the pregnancy bud period of sunflowers, it is necessary to apply potassium dihydrogen phosphate or phosphorus and potassium fertilizer to promote the differentiation of plant flower buds and increase the number of flowering of sunflowers.

1. Sowing time.

In addition to the low temperature in winter, sunflowers can not be planted, which can be sown in spring, summer and autumn, but many friends generally choose to plant in spring and autumn, Zhejiang, Shanghai, Anhui, Jiangsu and other places can start sowing in spring in April. In Sichuan, sowing is best in September and October; Hunan, Hubei, Jiangxi and other places can also sow seeds in March and April every spring; In the northern region, the sowing time is adjusted according to the local weather temperature, and as long as the temperature reaches about 20 degrees, the sowing can be started.

2. Planting method.

1. Sunflower seed selection.

Before planting sunflowers, you need to select the seeds, it is best to choose the seeds that are full of particles and have no damage, and the seeds of the dry plaque are decided not to choose, the purpose of this is to choose the best seeds to plant more easily.

2. Soak the seeds to promote germination.

Wash the sunflower seeds you selected with water, soak them in warm boiled water at 60 degrees for 24 hours, and then take them out and drain the indicated water after the seed skin becomes soft, and then place them on the culture* to pour enough water and place them in a sunny place, and they can germinate in 2 weeks.

3. * Soil preparation.

Sunflower seed planting is suitable for growing in good soil, so it is best to prepare it yourself when choosing soil, generally with peat*, rotting leaves*, and gardens * for 2:2:1 preparation, adding an appropriate amount of organic fertilizer as base fertilizer, watering an appropriate amount of water, and moistening the water farm.

4. Lighting control.

After sowing sunflower seeds, do not leave them in strong sunlight, especially in summer. It is best to place it on the balcony with a little astigmatism shining in, it is better to put it indoors in winter, but when there is sun, it is turned on and taken out to irradiate for one to 3-4 hours.

5. Fertilizer and water management.

Sunflower planting does not have very high requirements for water, and it is only necessary to keep the pot moist after planting, and it is generally watered when it is dry. Then there is fertilization every 3 weeks, mainly foliar fertilizer, which is more effective when it is dissolved in water.

It can be planted in spring, summer and autumn, most of the time in spring, if the southern region can choose to sow in mid-April, if it is more southern or northern, you can adjust the time appropriately, as long as the average temperature is about 18 degrees.

2. Planting method.

1. Sowing. Spread the seeds evenly in the soil and maintain the temperature above 20 degrees Celsius, and germination will take about 10 days.

2. Seedlings are planted.

When the seedling grows to a certain height, it can be planted, if you want to soil culture, the plant does not need to be planted with soil, and there is no need to water it often during the growth period. The row spacing of the plants is controlled, liquid fertilizer is applied several times, and it is important to remember that when the fruit is about to crack, the seeds need to be harvested in time, otherwise they will be scattered. If it is a bonsai, it is planted in the same way as soil culture.

3. Watering. Watering depends on the condition of the potting soil, generally if it is not dry, you don't need to water, if you water, you have to water it thoroughly at one time.

4. Correct fertilization.

It does not have high requirements for fertilizer, just apply potassium dihydrogen phosphate once every half a month, so that it can make its flowers big and bright, and the flowering period will be longer.

5. Light. It likes sunny places, so be sure to get plenty of sun as it grows, so that it can flourish.

6. Temperature. It prefers warm places, and the temperature for germination is optimally 21 to 24 degrees, so that the seedlings will grow in about a week or so.
