Sunflower is a plant that everyone is familiar with. Its seeds are people's favorite snacks, and its kernels can be used to extract oil after being collected. Now sunflower is one of the most important oil crops in China, and the economic benefits after planting are particularly high. Many people want to plant it on a large scale, but they don't know much about its planting method. Today, the editor will introduce it to you.

How to Plant Sunflowers

1. Choose seeds and land

When planting sunflowers, you must choose those sunflower varieties that are high-yielding and disease-resistant. Now the new generation of hybrid seeds has high yields and high oil yields, which is the best choice for people to plant sunflowers. The choice of land is also very important when planting sunflowers. It is not suitable for continuous planting, and it likes loose and fertile soil. After planting, the land should be deeply plowed, sufficient base fertilizer should be applied, and it should be leveled.

2. Sowing time

Sunflowers are a plant with strong cold resistance, so they are particularly suitable for early sowing. If you choose to cover the ground with plastic film, you can choose to plant them in early March each year. If you choose to plant them in the open field, you need to sow them in late March or early April. The best time to sow sunflowers in summer is between late June and early July each year.

3. Field management

Field management is also very important when planting sunflowers. The seedlings should be thinned out when the first true leaf grows after the seedlings emerge. Weeding should be done twice during the growth period. The first weeding can be combined with tillage. After the second weeding, the soil should be added in time to prevent the sunflowers from lodging.

4. Fertilizer and water management

Fertilizer and water management is also very important when planting sunflowers. This plant has a low demand for fertilizer in the early stage after planting, but more in the later stage. If you choose spring sowing, you can apply enough base fertilizer and apply topdressing after the sunflower grows eight pairs of true leaves. You can choose ammonium carbonate or uric acid for topdressing. Sunflowers are relatively drought-resistant, so they cannot be allowed to appear in the field in time. After they enter the flowering period, if the weather is dry, they need to be watered in time.
