Select seeds with uniform and full seeds, thick seed coat, high germination rate and no damage. Soak the seeds in warm water at 55 ~ 60℃ 10 ~ 15 min, and then soak the seeds in warm water.

The soaking time is 24 hours for soybeans, 24 hours for mung beans, 24 hours for red beans, 24 hours for peanuts, 24 hours for peas, 24 hours for broad beans, 24 hours for black beans, 6 hours for alfalfa and 6-8 hours for radish.

Sowing seeds, putting plates to accelerate germination; Newspapers should be laid in the seedling tray, and seeds should be sown evenly. Don't pile seeds. After sowing, spray water 1 time, cover with black cloth to keep moisture, put it on a shelf, water it 1 time every day, and change the position of the seedling tray. When most of the seeds are exposed, the seeds with dead buds, rotten buds, injured buds and dead grains are eliminated. Accelerating germination for 2 ~ 3 days at the appropriate temperature of 65438 08 ~ 22℃.

Watering; Keep the buds moist throughout the growth period. Sprinkle water 2 ~ 3 times a day in the early growth stage; In the middle and late growth period, water should be increased and sprayed 3 ~ 4 times a day. The amount of water drenched each time should be based on the degree of newspaper soaking, and water should not be accumulated at the bottom of the cultivation tray, so as not to cause rotten seeds.

Temperature; The optimum growth temperature is about 20℃, and it can grow at 12 ~ 30℃, generally controlled at 19 ~ 23℃.

Light; Under dark conditions, seedlings grow rapidly and are not easy to standardize. Keep the scattered light in the cultivation room before harvest and shade it in summer.

Greening; When the new buds grow to 4 ~ 5 cm, remove the mulch to make them green under the light.

Harvesting; It is required that the new buds are green, the height of the seedlings is about 10cm, the top leaves are unfolded, the stem tip is 8 ~ 10 cm, and there is no fibrosis. The general sales length is 8cm, and the crops can be 1 in high temperature season and 10 ~ 20 days in low temperature season.

Soybean 8- 10d, mung bean 8- 10d, red bean 12- 13d, peanut 5-7d, pea 8- 10d, broad bean 8- 10d and black bean 8-0d.
