There are many varieties of the sun, I like the red compound leaf sunflower, just fold a section, more than three centimeters, bury the soil more than two centimeters deep, compact, water some water... You can put a few more branches in a pot, and there are flowers blooming every day, and sometimes you can bloom twenty or thirty flowers a day when they bloom, which is very beautiful. . .

Sunflower Scientific name: Portulaca grandiflora Alias: Half-branched lotus, pine-leaved peony, Purslane grandiflora Genus:

Purslane family, purslane origin distribution Native to Brazil, South America. It is cultivated all over the country. 1-year-old fleshy herb, 10-15 cm tall.

Morphological characteristics The stems are thin and rounded, lying flat or oblique, with clumps of hairs on the nodes. Leaves scattered or slightly clustered, cylindrical, centimeter long. The flowers are apical, centimeter in diameter, with leaf-like bracts at the base, and the petals are brightly colored, with white, dark, yellow, red, purple and other colors.

The capsule is lobed when ripe, and the seeds are small and delicate, brownish-black. There are many varieties of horticulture, including single petal, semi-double petal, and double petal. Growth habit likes warm, sunny and dry environment, extremely resistant to barrenness, 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 6-7 months. Garden use Sunflower plants are short, the stems and leaves are fleshy and clean, the flower color is rich, and the flowering period is long.

It is advisable to arrange the periphery of the flower bed, and it can also be set up as a special flower bed. Whole herbs can be used as medicine. Propagation and cultivation Sunflower seeds are very small, about 8400 seeds per gram.

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.

It is extremely resistant to barrenness and can be adapted to general soils, and sandy soils with good drainage are the most suitable. It can be sown and reproduce by itself. 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.

Propagation with sowing or cuttings. Sowing can be done in spring, summer, and autumn. When the temperature is above 20, the seeds germinate and germinate about 10 days after sowing.

The soil should be thin, and it can grow without covering the soil. Seedlings are planted separately with a row spacing of 5 to 6 cm. Liquid fertilizer needs to be applied several times.

It can bloom in about 20 days under conditions above 15. Propagation by cuttings is often used in double-petaled varieties, where the cut shoots are used as cuttings in the summer, wilted stems can also be used, and flower buds appear after cuttings. Transplanting plants does not need to be soiled, and there is no need to water them frequently during the growing season.

The fruit cracks when it is ripe, and the seeds are easy to scatter, so they need to be harvested in time.

Sunflower belongs to the woody plants that grow for many years, because it is not cold-resistant, it is generally an annual planting deficit, it is in May, and now it is a good time to plant sunflowers. Sunflower can be sown and reproduced, can also be cuttings, if you want to bloom quickly, it is recommended to select cuttings, now the purchase of sunflower root seedlings is very cheap, and more mixed colors, after surviving colorful, ornamental value is better. Sunflower, everyone is familiar with it, belongs to the purslane family green plants, one of the most common green plants.

The petals are large, the colors are bright, and there are many shades.

The flowering period of the sunflower is long, how big the flowers are, and in the case of planting, remember to pre-embed pieces in the potting soil, (manure of chaff pig manure). This is followed by cultivation using permeable soil. It is a very good soil layer to mix with humus soil and garden soil and briquettes.

The first soil to be used when planting, generally speaking, can be integrated into the poor soil, so it is naturally best to choose high-quality sandy soil at the drainage pipe level. It likes to have enough sun, and if you can ensure that the sun is sufficient, you can see enough flowers and leaves.

This is a soft mode, the budding temperature is 21 to 24 degrees, about 7 10 days of germination, the seedlings are very subtle, so to maintain a higher temperature, the seedlings will develop quickly. The sowing time of sunflowers is generally chosen in spring, and it takes about 2 months from planting to full bloom. If you plant with a good friend or somewhere else, you need to protect the underground stems and water them moderately, so that they can bloom in three days, and the planting time can be in summer and autumn.

The problem of drought tolerance and moisture resistance of sunflowers.

If it is a potted plant sunflower, we must pay attention to the problem that the potted flower pot does not have to seepage, because if it happens, the sunflower will quickly rot and even die, so the planted bonsai soil must choose the soil quality of the drainage pipe. The most important area to pay attention to when planting sunflowers is to prevent cold and give as much sunlight as possible, the sunflower is high is the herbaceous plant flowers belonging to the genus Purslane, which prefers a long-term warm and humid natural environment, and the minimum maintenance of the ambient temperature is always maintained at more than five degrees.

When planting sunflowers, be sure to choose loose and fertile soil, and it should be in a place with good ventilation and lighting. Pay attention to the management of Huaiqing's late and reasonable Tian lead.

Sunflower seeds are relatively small, and they should be sown in sandy soil with no weeds and stones, and if the potting soil is not dry, do not water the socks again, so as not to accumulate water in the potting soil and lead to root rot.

Keep it in the light, but also make sure you water and fertilize it so that it can grow better. It is necessary to pay attention to overwintering, the time of cuttings, the ratio of cultivation soil, the process of fertilization, the container for planting and cultivating, and the work of raising and protecting.

Sunflower cultivation method.

Sunflower cultivation method. There are many people who like to cultivate their body and mind and want to raise some flowers, and the sunflower is undoubtedly a very good choice for us, and the sunflower is very beautiful after flowering. Next, I will take you to understand the relevant content of the cultivation method of sunflower.

Sunflower cultivation method 1

1. Soil. Sunflower does not have high requirements for soil at all, I personally feel that any soil can be planted, and there is no need for special nutrient soil, which feels a bit wasteful with good soil, and it can't hold down the roots, and it is easy to shake.

2. Moisture. Sunflower water requirements are not too high, it is also particularly easy to take care of, as long as you see dry watering on the line, generally once a week in spring, once in two or three days in summer, once a week in autumn is enough, if you want to be lazy in winter, you can do it once a month.

3. Temperature. Sunflowers like a warm and humid environment, so the temperature requirements are higher, the best growth temperature is almost 20 to 30 degrees, this temperature is very suitable for growth, so sunflowers can be in spring, summer, autumn can be put outdoors to raise in the open, winter to enter the greenhouse, or indoor breeding, otherwise it will freeze to death.

4. Illumination. Sunflower likes light very much, if you can, let it be in spring, summer, autumn has been put outside to bask in the sun, sunflower as the name suggests is like the sun, if it encounters a cloudy day or can not get the sun at night, then it will close its own flowers, and then bask until the sun itself opens again, isn't it amazing.

5. Fertilizer. Sunflower requirements for fertilizer are not high, usually watering when sprinkling a little compound fertilizer or urea on the line, to a small amount of more times, in May and June can be watered more, because of the sunflower'The flowering season is July and August.

The propagation of sunflower has seed propagation and cuttings propagation, seed propagation is relatively simple, as long as the seeds are sprinkled on the soil, and then watered thoroughly, there is no need to cover the soil, it will almost emerge in ten days, and then normal maintenance can be.

Cuttings propagation is relatively troublesome, cut off a pole and insert it into the soil, try not to damage the pole, the soil is hard and you can take the chopsticks to insert it, and then put the cuttings seedlings inside, and then water thoroughly, it is best to shade the shade above, it will grow roots after about ten days, and then you can bask in the sun.

1. Soil: Sunflowers are very easy to feed, so when raising sunflowers, just choose ordinary soil when preparing the soil. However, the fertilizer prepared for sunflower can be fermented with okara, which is good and does not cost money. And the method of fermenting okara is super simple.

2. Light: As I said before, the sunflower is very easy to feed, so it is good to give it normal light when the sunflower is maintained, as long as it is given enough light, the sunflower can grow luxuriantly.

3. Watering: When watering the sunflower, pay attention to check the bottom of the pot, if it is in summer, you should often check the bottom of the pot of the sunflower to see its air permeability, if the air permeability is better, you can water it every day, if the air permeability is not good, you can water it every other day.

4. Temperature: Because sunflowers like a warm environment, the temperature of sunflowers is better at 18 when sowing, and if you want it to sprout and grow well, the temperature is better at 21-24. Therefore, if the sunflower grows well, the temperature should not be too low, and it is better to keep it indoors in winter.
