When soybean pods are ripe, they will burst and pop out seeds in the sun. During the rainy season, seeds can spread. 1. temperature and light: soybean likes sunshine environment, suitable for seed germination 10- 12, optimum temperature 15-20, optimum growth temperature 20-25, and optimum growth temperature 20-28 during flowering and pod setting. If the temperature is lower than 14, the plants will not bloom, and if the temperature is too high, the plants will die. 2. Moisture and humidity: Soybean likes humid environment, and seeds need more moisture for germination. At flowering stage, the soil moisture content is about 75%, otherwise it will drop buds. Soybean needs less fertilizer before flowering, but it needs more fertilizer during flowering and pod setting, accounting for more than 80% of the total fertilizer absorption.

Soybean germination process

The growth process of soybean is mainly divided into four steps: sowing, germination, emergence and leaf extraction. First of all, when germinated soybeans are sown in wet soil, the appearance of the seeds will turn pale and the seed coat will crack slightly. After about two days, the soybean will grow pale yellow buds from the seed coat, and after five days, the soybean will grow symmetrical leaves. If soybeans are planted in soil to provide a suitable growth environment, they can emerge in about 4-6 days. Soybean is usually sown in spring, but it can also be planted in summer and autumn when the environment is suitable.

Direct planting of soybean seeds

First of all, we should choose full and robust seeds, pick out the broken and moth-eaten seeds, and then soak them in tap water for more than 12 hours, preferably not more than 24 hours. You can wash it twice in the middle, and it will germinate soon after accelerating germination.

Soybean seed germination

1. If you want soybeans to germinate smoothly, it is not recommended to choose genetically modified soybeans. It is recommended to go to the supermarket to buy genetically modified soybeans. 2. Put the soybeans into the container, and then pour the water into the container. Water is nothing but soybeans. Do not pour too much water. 3. After the previous step, let the soybeans stand for about five to eight hours, and then pour out all the water soaked in soybeans in the container. 4. At this time, you will find that the soybean is obviously bigger. Pick out the broken soybeans and move on to the next step. 5. Then cover the container with a thin layer of breathable cloth. Don't cover it too thick, it is not easy to seep and it is not easy to carry out the next operation. 6. Then sprinkle water every day to make the thin cloth slightly wet. Under normal circumstances, it takes about three or four days for small soybeans to germinate and grow vigorously.
