How to plant sunflower seeds? Teaching you the correct planting method
Sunflowers bloom facing the sun, very beautiful to look at, and they also produce sunflower seeds, which can be pressed for oil and also used as feed and snacks. So how do you plant sunflower seeds?
1. Soil: Sunflowers are also called oil sunflowers. Sunflowers can grow in fields and at the edges of fields, and can even grow quite well in saline-alkali soil. The only thing that needs to be satisfied is irrigation and watering. However, if you plant them in fertile, flat soil, they will grow better, and the sunflower seeds will be fuller. They can also be rotated with corn and soybeans.
2. Sowing time: The sowing time for sunflowers is not strict, as long as they are sown during the frost-free period. They can be sown as long as the temperature reaches above 10 degrees. You can choose to sow after Jingzhe in the lunar calendar, sow in early January, or sow in early March, but no later than late April, otherwise it will affect the planting of the next crop.
3. Fertilization: If you want them to grow better, they need more fertilizer, and generally no topdressing is needed. For one mu of land, applying three to five tons of farmyard manure is enough. The soil should be irrigated before sowing.
4. Planting density: Sunflowers are planted at 3000-6000 plants per mu. If the soil fertility is good, they can be planted a little thinner; if the soil fertility is poor, they can be planted a little denser. Sow in holes at equal spacing, with a plant-to-row spacing of 40-60cm, sowing 1-2 seeds per hole, or planting in wide and narrow rows is also acceptable. After sowing, cover with soil and cover with film to preserve moisture. After sunflowers sprout, do a good job of seedling management, check seedlings and fill gaps in time. After sunflowers are sown and sprout, seedlings can be replanted, but they must not be left unplanted.
5. Pollination: Sunflowers are pollinated by insects. Sunflower pollen is relatively heavy and not easily carried by the wind, so insects can only help with pollination. If the sunflower planting area is relatively large, bumblebees can be released for pollination. If the planting area is small, manual pollination can be chosen. For manual pollination, choose around 10 a.m. on a sunny day, bring a pair of adjacent flower heads together and rub them gently. Do this once every two or three days, and generally pollinating 3 times is enough.
6. Harvest: Around the end of June, sunflowers begin to turn yellow and withered, and this is the time when they can be harvested.
Sunflower seeds can be planted to grow beautiful sunflowers. Sunflowers have high ornamental value, and the seeds also have a wide range of uses after harvest, making them suitable for large-scale planting.
