How to Grow Soybean

Planting preparation

Planting preparation

Pick seeds

  • Good quality seeds have a higher germination rate and the plants will grow stronger. Therefore, before sowing, seeds should be screened to pick out diseased particles, moth-eaten grains, grains and broken petals.

  • In addition, in order to improve the purity of seeds, according to the typical characteristics inherent in this variety (such as grain type, grain color, seed size, umbilical size and color depth), weed out mixed heterogeneous seeds.


Dressing mud

  • Can choose general culture soil


  • Soybeans are short-day crops. Only when the length of daylight is shorter than the critical day length can they flower and bear fruit, otherwise only vegetative growth will be carried out.

  • Soybean is more sensitive to light. Because the soybean pods are distributed in the upper and lower parts of the plant, it is necessary to ensure that the plants growing in the soybean group receive sufficient sunlight for photosynthesis during the cultivation process in order to transport organic nutrients to the various parts of the pod.

  • It is recommended to grow soybeans outdoors.


Temperature management

  • Soybean is a warm crop and grows well in a warm environment. The minimum germination temperature is 6-18℃, and the germination is normal at 10-12℃; 15-25℃ is most suitable during the growth period.

  • Soybean seedlings have a certain resistance to low temperature. Generally, when the temperature is not lower than minus 4℃, soybean seedlings are only slightly damaged, and when the temperature exceeds minus 5℃, the seedlings are all damaged by freezing.



  • Soybeans require more water, but the requirements for water are different at different growth stages. From the initial flowering stage to the flowering stage, the soybean plants grow fastest and the water requirement increases. The soil is required to be sufficiently moist, but not too much rain, the climate is not wet or dry, and the sun is sufficient.

  • Different seed sizes require different amounts of water. Generally, large seeds require more water and are suitable for cultivation in areas with abundant rainfall and wet soil; small seeds require less water and are mostly planted in arid areas. The frequency of watering depends on the soil moisture, it is generally recommended to water one to three times a week.



  • Soybean has strong adaptability to soil, and almost all soils can grow. The number of fertilization should not be more than three times. It is recommended to fertilize during the nutrition period, flowering period and pod period.  


Wind and rain

  • Use general weatherproofing measures and temporarily move to indoor planting if circumstances permit.

Rhizobium usage

Rhizobium usage

Rhizobium should be inoculated at the seedling stage, the steps are as follows:

  1. Add 1-2 ml of water to Rhizobium with a dropper

  2. Make Rhizobium evenly dispersed in liquid in water

  3. Dilute Rhizobium with water

  4. Add 2 ml of diluted Rhizobium evenly to each pot

Cleaning tool method:

  • The tool used for Rhizobium inoculation can be immersed in 1:49 bleach for 1 hour after use
