How long can bean seeds germinate when planted in soil?

The more appropriate the temperature, the faster the germination. The temperature is 25-30℃ and the humidity is suitable. It takes 3-4 days to germinate, and 7- 10 days to germinate at/kloc-0-25℃.

Generally speaking, the water required for seed germination does not exceed 50% of the seed amount. At this time, too much water is easy to cause seed rot, so it is necessary to provide a loose and breathable soil environment for seed germination. Therefore, when planting in the open field, the sowing date should avoid the continuous rainy and low temperature weather, and at the same time, the soil moisture should be strictly controlled.

Extended data:

Generally, the flowering and pod-setting period is 5.0-60 days from the plant budding to the end of bean harvesting. It usually takes 5-7 days from budding to flowering, 8- 13 days from flowering to harvesting of commercial pods, and 4- 10 days from commercial pods to physiological maturity. In the good period of flowering and pod setting, on the one hand, beans pull out inflorescences to blossom and pod setting, on the other hand, they continue to grow stems and leaves, develop roots and form nodules.

The root system of kidney bean has wide adaptability to soil, but the soil with fertile, good drainage and good air permeability is the best. Too sticky and low humidity soil is not conducive to root growth and nodule activity. The root system of snap bean is developed, but its regeneration ability is weak. The depth of taproot is generally between 80 ~ 100 cm, and the cluster roots are mainly distributed in the plough layer of 15 ~ 18 cm, with few lateral roots and nodules, and the nitrogen fixation ability is relatively weak.
