Sunflower has a wide adaptability to soil and can adapt to heavy clay to light sandy soil. It must be resistant to acid and alkali. Generally, the acidity and alkalinity can grow between 5.5 and 8.5. During soil preparation, the soil is carefully prepared, the soil is deeply turned over, the soil is broken, and hard objects such as stones are removed. And apply enough base fertilizer.

2. Seed selection treatment

Select seeds with good varieties, fast growth, high yield, and strong stress and disease resistance. Seeds with full grains, shape, size and color are the best, while those with poor quality should be eliminated. Before sowing, the seeds should be treated. First, the selected seeds should be exposed to the sun for 2-3 days, and remember to turn them in time when drying the seeds.

Intertillage weeding is carried out 2-3 times a year to ensure the strong growth of sunflowers, the first time can be carried out between seedlings, intertillage 3-4cm, topdressing appropriate amount of urea, the second in the first week, when deep ploughing 8-10cm, the third time at the end of the plate, deep ploughing 3-4cm, topdressing fertilizer. Artificial pollination of sunflowers is extremely important, because sunflowers are cross-pollinated crops. Artificial pollination can increase seed setting rate, yield and income.
