How many days does soybean germinate? What are the conditions for seed germination?

Soybean is a common food on the table and a common cash crop in China. The main breeding method is sowing, which can generally be carried out in May-June.

Soak soybeans in clear water for 3-4 hours before sowing, take them out, keep the temperature above 35℃, water them once every 10 hour, twice a day, and germinate for about 4 days. When the weather is cool, it takes 7- 10 days for soybean germination.

Soybean emergence time

Under the condition of loose and breathable soil and suitable temperature and humidity, soybean can emerge in 7- 10 days after sowing. If there is enough rain after sowing, the emergence speed will be accelerated, and the emergence will take about 5 days.

Post-emergence management of soybean

1, replanting

After soybean emergence, it should be checked regularly. After discovering the lack of seedlings, the seeds of the same variety should be soaked in time, and then replanted, or replanted under the room.

Step 2 weed

Weeding should be done in time at soybean seedling stage to prevent weeds from competing with soybean seedlings for nutrients, promote the absorption of nutrients by soybean seedling roots and ensure the healthy growth of soybean seedlings.

3. Flood control

The growth period of soybean seedlings is generally in summer, with high temperature and heavy rainfall. High temperature and humidity can easily lead to root rot and even seedling death of soybean. So it is necessary to drain water in time.
