How to sow sunflowers, how to grow sunflowers

1. Scattering 2, scattering 3, strip seeding 4, machine seeding.

1. Seed treatment before sowing

1. Generally, seeds that are easy to germinate can be soaked in cold or warm water before sowing, and the water temperature should be controlled below 40 degrees to make the seed coat soft or the seeds swell and then sown.

2. Seeds with hard seed coat, due to the hard seed coat, impermeable and impermeable, can be used to cut the seed coat, pesticide treatment and other methods.

3. For seeds that require dormancy under low temperature and wet conditions, they are often treated by freezing and low temperature layering (i.e., sand storage).

Second, the sowing period

Flowers are usually sown in the spring when the weather is already warmer. However, there are many species, some species that bloom in winter and spring are often sown in late summer and early autumn, and those with a short growth period can also be sown in late autumn and early winter.

3. Sowing

Flowers are generally made of 3 parts of peat soil and 1 part of Gaza for sowing soil; It can also be used as soil for sowing with humus or fine sand; <> is still available

Find a flat piece of land, put in the sunflower seeds soaked in warm water, too.

It will germinate after four or five days, and then it will be watered and fertilized constantly.

1. To plant a sunflower, Xinyin should pick its seeds first. If you want to grow sunflowers in a pot, you can choose small sunflower seeds for ornamental use.

2. If it is to be planted in a large flower bed or yard, you can choose the edible type.

3. After picking the seeds, sow them at a temperature of about 20 degrees Celsius, bury them in the soil, and wait for the seed buds to break through the soil and open the cotyledons before transplanting.

4. When transplanting, it is necessary to transplant with soil, and after transplantation, it is necessary to pay attention to watering and watering enough, and the light is appropriate.

The correct way to grow sunflowers is to soak the seeds in warm water for germination, and then spread the seeds evenly into sandy soil.

In order to improve the germination rate of sunflower seeds, after selecting healthy seeds with full particles, suitable size, and no diseases and pests, the seeds are germinated, and the seeds prepared by Tong Juxiao are soaked in warm water of 30 to 40 degrees until the seeds absorb enough water to split and germinate, and then take out the seeds and prepare for sowing.

Before planting sunflowers, you need to choose a loose and breathable, well-drained, humus-rich sandy soil, plough the prepared soil and weed, and then apply enough basal fertilizer to the soil to provide sufficient nutrients for plant growth.

Sow the sunflower seeds evenly into the soil, water them once after sowing to keep the soil moist but not waterlogged, and then put the plants in a sunny, ventilated and breathable environment to maintain, and the seeds can germinate after five to seven days.

Growth characteristics of sunflowers

1. Life is tenacious.

Sunflower has strong vitality, low requirements for soil, can grow normally on various soil qualities, and the plant also has salt tolerance, can absorb salt, after modification, can be used as a kind of crop to improve the soil.

2. High water demand.

The water requirement of sunflowers is different at different growth stages, from sowing to budding stage, the water requirement is the total water requirement, and from the budding to flowering stage, in the peak demand period, the water requirement is 43% of the total water requirement.

3. Sun-loving nature.

Sunflower is a sun-loving, short-day scattered plant, vigorous growth needs sufficient sunlight to bloom and pollinate normally, improve the fruiting rate, if the plant is in a dark environment for a long time, the quality of the seeds is not good, and the yield will also be reduced.

The correct way to plant sunflowers: germination treatment, soil selection, start sowing, timely transplanting, and post-maintenance.

1. Germination treatment: Sunflower can be sown directly, or it can be germinated first, which can improve the seedling emergence rate, and the seeds can be wrapped in wet towels and placed in a ventilated environment, and they will generally germinate in two or three days.

2. Soil selection: Sunflower seeds prepare the soil before entering the soil, choose the area with good sunshine and loose soil, it is best to dig deep first, and then apply the appropriate amount of base fertilizer to improve soil fertility.

3. Start sowing: when sowing, spray the seeds evenly in the soil, cover them with thin and fine soil, water them immediately after sowing to keep the soil in a moist state, and after sowing, transfer them to a sunny and breathable environment for maintenance. Usually after 5-7 days the seeds germinate and resume.

4. Timely transplanting: sunflower seedlings can be transplanted after growing three or four leaves, pay attention to the balance between the seedlings when transplanting, and water thoroughly after transplanting, so that they can recover their growth as soon as possible.

5. Later maintenance: sunflower does not have very high requirements for water, watering should not be too frequent, the temperature of the breeding environment is best controlled between 2-15, and the fertilizer is selected as compound fertilizer, which can be more frequent to help it grow better.

The whole process of sunflower planting method is to select and prepare the land, prepare seeds, sow seedlings, and carry out planting.

First, the selection of land preparation.

Before planting sunflowers, choose the soil for planting, choose a flat land, deep soil layer, medium fertility, convenient irrigation and drainage, relatively small soil stickiness, and not choose a plot with heavy stubble. After selecting the planting plot, the soil should be organized, deeply turned, and decomposed fertilizer should be applied to improve the fertility of the soil.

2. Prepare the seeds.

If you want to plant for ornamental use, you can choose dwarf sunflower seeds, and choose seeds with full grains, no diseases and pests, and good quality, and suitable seeds can improve the germination rate of planting. Treat the seeds in advance, dry the seeds in advance, and then mix the seeds with a new high-fat film, which can repel underground pests, avoid virus infection, and also improve the germination rate of seeds.

3. Side-cavity sowing seedlings.

Sunflowers can be sown in April every spring, when the temperature is around 20, and the seeds are planted in the soil with the tips of the seeds facing down. After sowing sunflowers, cover them with a thin layer of soil and water them thoroughly, and they will germinate in about 3-5 days.

Fourth, carry out colonization.

When sunflower seedlings grow to a height of 20 cm, they can be colonized, planting the seedlings into the soil, maintaining a row spacing of 50 cm to 100 cm. Once planted, pour enough water into the soil. After the growth is stable, it can receive sufficient light and spray potassium dihydrogen phosphate solution to supplement nutrients.

Tips for planting sunflowers

1. Seed selection: Choose good quality sunflower seeds to ensure that they are fresh and adapted to local climatic conditions. You can buy sunflower seeds from a florist, gardening center, or ** store instead.

2. Soil and planting location: Sunflowers prefer soil rich in organic matter and well-drained. Choose a location that is full of sunlight, away from the shade of high walls or large trees. Make sure there is enough space in the planting location, as sunflowers can grow quite tall.

3. Sowing and growing: In the right season, sprinkle sunflower seeds directly on the prepared soil, and then gently cover a small layer of soil. Keep the soil moist, but don't overwater it.

Sunflowers usually require a long growing period, so patience is required to wait for them to ripen.
