When is the best time to plant soybeans?

Soybean belongs to the genus Glycine max in the family Leguminosae. It is an important crop that is rich in protein, fat, carbohydrates, vitamins and minerals. It is a high-quality source of plant protein. Soybeans can be eaten directly or processed into soy products such as tofu, soy milk, soy milk, bean skin, bean sprouts, etc. They are also the main raw material for soybean oil . Let’s learn together when is the best time to sow soybeans?

When is the best time to plant soybeans?

Spring soybeans: Spring soybeans in the north are usually sown from late April to mid-May, in the Huanghuaihai region from late April to early May, and in the south from late March to early April.

Summer soybeans: Summer soybeans are generally sown after the wheat harvest, around mid-June, and mature from September to early October. Autumn soybeans: Autumn soybeans are planted earlier, usually in July, and begin to be harvested around October.

Soybean sowing methods and precautions

1. Seed treatment

Soybean seeds should be screened before sowing, and healthy and plump seeds should be selected. Seeds can be dried in the sun to increase germination rate and reduce pests and diseases. Use seed dressing agent for seed coating to prevent pests and diseases and increase germination rate.

2. Soil Preparation

Deeply till the soil to ensure that the soil layer is loose and to increase soil aeration and drainage. Apply sufficient base fertilizer, including organic fertilizer and compound fertilizer , to provide the nutrients needed for soybean growth.

3. Sowing method

Row sowing: Dig furrows in the field at a certain row spacing, sow the seeds evenly into the furrows, and then cover with soil.

Hole sowing: Dig holes at the predetermined plant and row spacing, sow 2-3 seeds in each hole, cover with soil and lightly compact the soil.

5. Seeding depth

The sowing depth is generally 4-5 cm to ensure good contact between the seeds and the soil, while avoiding being too deep or too shallow to affect germination.

6. Seeding density

The sowing density is determined according to the soybean variety , soil fertility and field management level. Generally, the row spacing is 60-70 cm and the plant spacing is 10-20 cm.

7. Notes

The soil should not be too wet or too dry during sowing, and the soil moisture should be maintained at 60%-70% of the maximum water holding capacity of the field. Choose disease-resistant varieties and treat seeds in time to reduce the occurrence of diseases and pests. Avoid continuous cropping, implement a reasonable crop rotation system, and reduce the occurrence of soil-borne diseases and insect pests. Sow seeds in time according to climatic conditions and soil temperature to avoid affecting the growth cycle and yield of soybeans due to sowing too late.

Field management should be carried out in time after sowing, such as seedling replacement, weeding, fertilization and irrigation. Consider local climate conditions and choose appropriate soybean varieties to adapt to possible drought, frost or other climate risks. Ensure that fields are well drained to avoid standing water which can lead to root diseases. Apply nitrogen, phosphorus, potassium fertilizers and trace elements reasonably according to soil test results and soybean growth requirements.

In conclusion, soybean is an important food crop and its sowing time varies according to region and climatic conditions. You can choose according to the climatic conditions of your area.
