Growing mung bean sprouts at home is a simple and fun process. Here are the detailed steps and precautions: 1. Preparation work
1. Seed selection: Use mung beans with plump particles, bright green color, and no pests or diseases as seeds. You can purchase seeds specifically for growing bean sprouts in the market, or choose from your own preserved mung beans- Avoid using green beans that are damp, moldy, or infested with insects.
2. Container preparation: - Choose a clean, oil-free container with drainage holes or breathable bottom, such as a plastic basin, ceramic basin, glass container, or plastic basket with breathable holes- The size of the container should be selected based on the number of plants planted to ensure sufficient growth space for mung beans.
3. Tool preparation: - Prepare a clean damp cloth or tissue to cover the mung beans- Prepare a black plastic bag or newspaper for shade. 2、 Planting steps
1. Soaking seeds: Place mung beans in a container, add an appropriate amount of water (with a water temperature of 20-25 ℃), and soak for 8-12 hours- During the soaking process, gently stir the mung beans to allow them to fully contact the moisture.
2. Drain water: After soaking, remove the mung beans and drain the water with gauze or a filter- Place it in a well ventilated area to allow the moisture on the surface of the mung beans to evaporate naturally.
3. Sowing: Spread the drained mung beans evenly at the bottom of the container- Cover the mung beans with a damp cloth or tissue to keep them moist.
4. Watering and shading: Watering 2-3 times a day to keep the mung beans and damp cloth moist- Wrap the container in a black plastic bag or newspaper to create a dark environment. Pay attention to maintaining good ventilation to prevent seeds and bean sprouts from rotting due to lack of oxygen.
5. Temperature control: Place the container in a warm and ventilated place, keeping the temperature between 20-25 ℃. Avoid direct sunlight and high temperature environments. 3、 Harvesting and Preservation
1. Observing growth: Generally speaking, mung bean sprouts can be harvested 3-5 days after planting. Pay attention to the growth of bean sprouts, and pick them when they reach 5-10 centimeters in length.
2. Picking and Cleaning: Gently remove the bean sprouts from the container, taking care not to damage the roots of the sprouts- Wash the bean sprouts with clean water to remove any remaining shells and impurities.
3. Storage: Put the picked mung bean sprouts into a fresh-keeping bag, seal the mouth, and refrigerate them in the refrigerator. Green bean sprouts stored in refrigeration can be preserved for 3-4 days. 4、 Precautions
1. Hygiene: Keep containers and tools clean and hygienic during the planting process to avoid contaminating seeds and bean sprouts.
2. Light and temperature: Although seed germination may not require sunlight, the growth of bean sprouts requires a certain amount of light and suitable temperature. Avoid direct sunlight and high temperature environments, while maintaining good ventilation.
3. Watering: Watering should be done in moderation, avoiding too much or too little. Excessive water can cause mung beans to soak in water and rot; Insufficient water can dry mung beans and bean sprouts, affecting their growth.
4. Harvest time: The harvest time should be appropriate, as being too early or too late can affect the taste and nutritional value of bean sprouts. Pick the bean sprouts in a timely manner when they reach a certain length.
