How to Grow Bean Sprouts: Methods and Step-by-Step Guide
Bean seedlings have a fresh fragrance, are crisp and delicious, rich in nutrients, and also offer various therapeutic benefits, making them very popular with modern people. As a leafy green vegetable, they have excellent growing prospects, so today we will introduce the growing methods.
Field growing methods
(1) Requirements for cultivation facilities and location
① Location requirements: To produce bean seedlings, an enclosed balcony or a winter-warm greenhouse can be used. The suitable growing temperature is 18-23°C, humidity around 80%, and strong light is not needed.
② Seedling tray: The trays used for producing pea seedlings must be sturdy, durable, lightweight, and have good air permeability. Black plastic seedling trays are generally preferred.
(2) Cultivation techniques
① Plot selection: Pea seedlings are suitable for growing in slightly elevated land with convenient drainage and irrigation, and in relatively fertile, loose, neutral to slightly alkaline soil.
② Seed selection: Choose green peas or speckled peas with thick seed coats, small grains and plumpness. Pea seedlings produced from these peas have thick stems and leaves, grow quickly, and have strong disease resistance.
③ Sowing time: The optimum temperature for pea seed germination is 18-20°C. Sowing can be scheduled for early spring in February-March or September-October. In warm regions, sowing can also be done from the end of October to January of the following year
④ Management: Apply topdressing twice before harvest, and once after each harvest. Topdressing should mainly be quick-acting nitrogen fertilizer. Pea seedlings are susceptible to waterlogging, so during the growing period pay attention to clearing ditches and draining water to prevent root rot, but they should not be too dry either; keeping the soil moist is sufficient. After rain and after fertilizing, appropriately remove weeds, and pay attention to guiding the vines so they do not grow into the furrow. Regarding pests and diseases, there are powdery mildew, yellow spot disease, yellow top disease, etc., which should be controlled promptly.
⑤ Harvesting: 30-50 days after sowing, when the seedlings are 10-15 cm tall and the sprouts are light yellow-green, begin picking the tender shoots, that is, pick the upper tender shoots. After that, harvest once every 15-20 days. Generally, 6-10 harvests can be made.
