When planting and cultivating bean seedlings, you can choose beans with high yield, fast growth and good quality. The storage time should not be too long, and you can choose new seeds of the same year or one year. After selecting seeds, broken, deformed and withered seeds can be screened out, leaving only healthy seeds.
Step 2 prepare the seedling tray
Prepare a seedling tray for later seedling raising, which needs disinfection and sterilization before use. Spread two layers of moisturizing paper or non-woven fabric on the seedling tray, and spray water on it to moisturize, which provides a good growth environment for bean seedlings to germinate.
3, soaking seeds to accelerate germination
Before sowing, the seeds can be selected and soaked in hot water at 55℃ for 15 minutes to avoid scalding. When the water temperature drops to about 25℃, the seeds can be soaked for about 5-6 hours. After soaking and absorbing water, you can take out the seeds, wrap them with wet cloth and put them in an environment of 20-25℃ to accelerate germination. When most seeds are found to germinate, they can be taken out for sowing.
Step 4: sow seeds
Spread the seeds evenly on the plate, keep a good spacing and don't let the seeds overlap. Put the beans in a ventilated place, not under strong light, but in the shade or covered with black plastic film, which can promote the growth of bean seedlings in the dark. Spray water 2-3 times a day, and seedlings will emerge in a day or two.
