Before planting sunflowers, it is necessary to prepare and fertilize the soil, choose sunny, loose, breathable and well-drained soil, tidy up the soil and apply rotten base fertilizer.

The sowing time of sunflower is usually arranged from March to April, when the climate is suitable and conducive to the germination and growth of seeds. The appropriate sowing temperature is very important for the growth of sunflowers. Generally speaking, the temperature should be kept between 18 and 25 ℃. After sowing, the expected budding time is about 5 to 7 days.

The sowing time of sunflowers depends on the time it takes to blossom, so they can be sown all year round. Usually, you choose to sow seeds from January to April or from September to October, so that flowers can be seen 60 to 70 days after sowing.

If it is in the south, the planting time can be advanced appropriately. If the northern region, the temperature is low, can not be planted too early, the temperature is low, it will affect seed germination.

5. Sowing time of sunflower: there is a difference between early-maturing species and late-maturing species, the growth period of the former is about 100 days, and the latter is more than 130 days. Due to the different climate of varieties and regions, the sowing time is also different. Early sunflower in Hebei Province is more than early April sowing, late sunflower sowing in late June.

What is the time and method of sowing sunflowers?

Sunflower sowing time is from April to June. The method is to choose loose and breathable humus soil to plant. Sunflower seeds can be carried out from April to June every year, during which the temperature is more suitable and the precipitation is moderate, which can make the sunflower seeds germinate better.

Sunflowers can reproduce by sowing. Although there is no strict requirement of sowing season, spring is usually chosen for sowing, and the best time is around April, that is, around Ching Ming Festival. At this time, the temperature is moderate, about 20-25 degrees Celsius, which is conducive to seed germination and growth.

The planting time of sunflowers is usually sown between April and June every year. The temperature during this period is within the suitable range of plant growth, which is conducive to seed rooting and germination. After planting, sunflowers will sprout after waiting for 10 to 15 days. Usually golden flowers can bloom in summer.

Sunflower seed planting method and time: planting time, breeding treatment, sowing and seedling raising, seedling management, transplanting and planting. Planting time the best planting time for sunflowers is around April to June every spring, during which the temperature can be maintained at about 18-25 ℃, which is the most suitable for planting and conducive to seed germination and growth.

Studies have proved that early sowing in the northwest of Jilin Province has become one of the important factors restricting sunflower yield, and timely late sowing is an important measure to increase production. The sowing date of conventional sunflower varieties is from May 10 to 20, and that of sunflower hybrids from May 25 to June 10. The sowing date of oil sunflower hybrids is from May 30 to June 20.
