Planting techniques of sunflower

Sunflowers are very easy to survive, so the planting technique of sunflowers is very simple. Although simple, but the sunflower planting technology in the operation process should pay attention to the following points.

Sunflower seeds are very small, about 8400 per gram, often sown on seedling trays, very slightly covered with fine vermiculite, or only slightly compacted after sowing to ensure adequate moisture. The germination temperature is 21: 24 degrees Celsius, about 7: 10 days, the seedlings are extremely weak, so if the temperature is kept high, the seedlings grow very fast and can form sturdy, fleshy branches and leaves. At this time, the seedlings can be directly on the basin, using a basin of about 10 centimeters in diameter, planting 2-5 plants in each pot, with a high survival rate and rapid growth. Extremely resistant to barren, all kinds of soil can adapt, and sandy soil with good drainage is the most suitable. Can sow and reproduce itself. See the sun blossoms and close in the morning, evening and cloudy days, so it is known as sunflowers and noon flowers.

To propagate by sowing or cutting. Seeds can be sown in spring, summer and autumn. The seeds germinate when the temperature is above 20 degrees Celsius and germinate about 10 days after sowing. The soil cover should be thin, and it can grow without it. The seedlings were planted separately with a row spacing of 5 × 6 cm. Liquid fertilizer should be applied several times. It can blossom in about 20 days under the condition of above 15 degrees Celsius. Cuttage propagation is often used for double-petal varieties, cutting shoots are used as cuttings in summer, wilting stems can also be used, and buds appear after cutting. Transplanting plants do not need to carry soil, and do not need to be watered frequently during the growing period. The fruit will crack as soon as it is ripe, and the seeds are easy to be scattered and need to be harvested in time.

Planting techniques:

Planting techniques of sunflower: seed propagation: sowing in Sichuan from September to October, before sowing, prepare the land, open a ditch 1.3 meters deep, open a horizontal ditch according to the row spacing of 30 centimeters, a depth of 4 centimeters, and sow about 10 centimeters, so that the soil is flat and loose. The seeds need to be accompanied into the grass ash mixed with human and animal dung water to turn into seed ash. 5-6 taels of seeds are used per mu. When sowing, first apply human dung water in the ditch and spread the seed ash evenly.

Planting techniques of sunflowers: split propagation: after the summer harvest, dig out the old pockets, select the ones that grow well, divide them into small pockets, plant them according to row spacing of 30 cm and plant spacing of 7-10 cm, and pour them into livestock dung water.

Sunflower planting technology 3: field management: seed propagation, when the seedling height-centimeter, watering-times light human and animal dung water to lift seedlings. When the height of the seedling is 3cm to 4cm, the seedling should be evenly distributed and replenished. Leave a seedling every 3-4 cm, and the supplementary seedlings should be carried with soil. After leveling the seedlings, they were ploughed and weeded for one time, and topdressing was carried out in parallel. If the plant is propagated, the new seedlings will be removed after planting and topdressing for one time, and then only need to pull grass and loosen the soil, and then top dressing for the winter after harvest in September and November.

The planting method of sunflower

Sunflowers not only have the characteristics of blooming in the sun and closing in the morning, evening and cloudy days, but also have many colors. Flower friends like to plant sunflowers, and the planting method of sunflowers is not very difficult. Flower friends can not only sow seeds, but also cut.

Daily maintenance of sunflower planting

Sunflowers are best preserved in a sunny environment. If the light is weak, there will be overgrowth, few flowers or even no flowering. Sunflowers are more resistant to barren, so the basin soil can adapt. If you can use sandy soil with good drainage, you can keep the basin soil-constant humidity at ordinary times, and apply potassium hydrogen phosphate (or other flowering fertilizer) half a month. It will be able to achieve the effect of large and colorful flowers and continuous blooming.

Sowing the planting method of sunflower

Sunflower seeds are very small, about 8400 per gram, can be sowed in spring, summer and autumn, often sown in seedling plates, and can be slightly covered with or without soil after sowing. The germination temperature is 21: 24 degrees Celsius, about 7: 10 days, the seedlings are extremely weak, so if the temperature is kept high, the seedlings grow very fast and can form sturdy, fleshy branches and leaves. At this time, the seedlings can be directly on the basin, using a basin of about 10 centimeters in diameter, planting 2-5 plants in each pot, with a high survival rate and rapid growth.

The cutting of the planting method of sunflower

Sunflower is very easy to cuttage, cut branches in summer as cuttings, wilting stems can also be used, after the emergence of buds, transplanting plants do not need to carry soil, the growing period does not need to be watered frequently.

Winter management of sunflower

In winter, the sunflowers can be moved indoors to the sun, so that the pot soil is dry and can safely survive the winter. after the Qingming Festival the next year, the flowerpot can be placed outside the window. In case of a cold spell, it is necessary to go into the window for maintenance.

Cultivation techniques of sunflower

Now it is cultivated all over China, with a wide variety of flowers and colors, light fragrance, easy to raise and easy to survive. Sunflower planting method is not very difficult, flower friends can not only sow, but also cuttage, today I would like to introduce the cultivation techniques of sunflower.

Cultivation techniques of sunflower:

Sowing: sunflower seeds are very small, about 8400 per gram, can be sown in spring, summer and autumn, often sowing in seedling plates, after sowing can cover a little bit of soil, or not. The germination temperature is 21: 24 ℃, about 7: 10 days, the seedlings are extremely weak, so if the temperature is kept high, the seedlings grow very fast and can form sturdy, fleshy branches and leaves. At this time, the seedlings can be directly on the basin, using a basin of about 10 cm in diameter, planting 2-5 plants in each pot, with a high survival rate and rapid growth.

Cutting: sunflower is very easy to cuttage, cut branches in summer as cuttings, wilting stems can also be used, buds appear after planting, transplanting plants do not need to carry soil, do not need to be watered frequently during the growing period.

For the winter management of sunflowers, sunflowers can be moved indoors to reach the sun in winter, so that the basin soil can be dry a little bit, and the flowerpots can be placed outside the window after the Qingming Festival the next year. In case of a cold spell, they still need to go into the window for maintenance.

Daily maintenance: sunflowers had better be placed in a sunny environment for maintenance. If the light is weak, it will grow too long, and the flowers will not even bloom. Sunflowers are relatively resistant to barren, so the general basin soil can adapt. If there are conditions to use sandy soil with good drainage, usually maintain a certain humidity of the basin soil, apply 1/1000 potassium dihydrogen phosphate (or other flowering fertilizer) once a month. It will be able to achieve the effect of large and colorful flowers and continuous blooming.

Sunflower cultivation techniques are introduced here, sunflower is also known as pine leaf peony, purslane, Portulaca oleraceae, Portulaca genus. Like the warm, sunny and dry environment, see the sun blooming, morning, evening, cloudy days close, so it has the name of "sunflower, noon flower".
