When to plant summer soybeans?

Summer-sown soybeans refer to soybeans sown in summer. Because summer has plenty of sunshine and the climate is warm and humid, these conditions are conducive to the growth and development of soybeans. Therefore, under proper cultivation management, the yield of summer-sown soybeans is usually higher than that of soybeans planted in other seasons. So when should summer soybeans be planted? Let’s learn more about it below.

When to plant summer soybeans?

The suitable sowing time for summer soybeans is generally in mid-June, and no later than early July. However, the specific time needs to be flexibly adjusted according to factors such as local climate, soil conditions and crop planting habits to ensure that summer-sown soybeans can grow smoothly and achieve a good harvest.

How to plant summer soybeans?

1. Variety selection

Choose soybean varieties with high yield, high quality and strong adaptability, such as Xudou 18, Ruidou No. 1, Sudou 13, etc.

2. Land preparation and fertilization

Before sowing, the land should be prepared, the tillage layer should be loosened, and the root stubble should be turned over. In combination with land preparation, apply 2-3 cubic meters of farmyard manure and 15 kg of diammonium phosphate per mu. You can also use 15 kg of triple compound fertilizer or 25 kg of soybean-specific fertilizer as base fertilizer.

3. Seed treatment

It is recommended to mix seeds with seed dressing agent before sowing. Choosing a compound agent with a long lasting effect, such as 35% thiamethoxam•carboxin suspended seed coating agent, can prevent diseases and pests and reduce the use of pesticides in the seedling stage. If you need to mix the seeds with micro-fertilizer at the same time, you should mix the micro-fertilizer first, dry it in the shade, and then coat it.

4. Precision seeding

Precision sowing is adopted during sowing, with 1 seed per hole. The general cultivation row spacing is 40 cm, the sowing depth is 3-5 cm, and the plant spacing is generally 12-15 cm depending on the variety. The sowing amount per mu is 4-5 kg, ensuring that about 15,000 seedlings are left per mu.

5. Post-broadcast points

After soybean sowing, the seedlings should be checked and replanted in time. When the bean petals just emerge, you should go to the field in time to check the seedling situation. If there are missing seedlings or broken ridges, you should first find out the reasons, and then replant the seedlings in time according to different situations.

Generally speaking, summer-sown soybeans are naturally sown in summer, but the specific time should be determined based on actual planting conditions. In addition, by paying attention to the above planting points, farmers can better implement summer soybean sowing work, promote soybean growth and development, and increase yield and quality.
