Planting techniques of sprouts

Sprouts are often referred to as sprouts and bean sprouts. Common varieties include soybean sprouts, mung bean sprouts, red bean sprouts, peanut sprouts, pea sprouts, radish sprouts, etc., which are eaten by young organs of plants. Because of less seed pollution, fast growth speed, easy regulation of environmental conditions, short growth cycle and high production and economic benefits, let's take a look at sprouts planting techniques.

Selected seeds

New seeds with a germination rate of more than 95%, high purity and purity, full grains and no pollution should be selected. In particular, Toona sinensis seeds are easy to lose their germination power under high temperature, and more attention should be paid to the selection of new seeds without summer (rub the wings before use). When sprouts are cultivated with such seeds, the seedlings grow fast, sturdy, slow fiber formation, low yield, tender quality and no pollution.

Soaking seeds to accelerate germination

Rinse the selected seeds with 20: 30 ℃ of water for 2 times, then soak them in water of 2 to 3 times the seed volume. Winter time is slightly longer, summer is slightly shorter, generally pea 18 hours, Toona sinensis 12 hours 20 hours, buckwheat 24 hours 36 hours, radish 6 hours 8 hours. After soaking the seeds, rub off the seed coat mucus, drain the excess water, put the seeds in a flat-bottomed container, cover with a wet towel, put peas at 18: 22 ℃ and Toona sinensis at 20: 23 ℃ to accelerate germination. Peas, buckwheat, Toona sinensis after 48 hours, radish 24 hours later, buds up to 2-3 mm before sowing.

Sowing technology

Wash the sowing plate, cover the bottom with 1 / 2 layer of white paper (or old newspaper), make the paper absorb enough water, spread the germinated seeds evenly on the wet substrate, generally 60 × 25 × 5 cm plate, sow 350 × 400 g of pea, 150 × 170 g of buckwheat, 80g of 100g of radish and 30g of Toona sinensis. After sowing, stack the seedling plates neatly and cover them with black plastic film. Peas are 18 ℃, buckwheat and radish 20 ℃. Toona sinensis "stacked plate to promote budding" at 20: 23 ℃. 2 days later, the bud was as high as 2-3 cm, and the seedling plate could be "put on the shelf" and began to grow in light at this temperature.

Sprout management

1. Light: buckwheat sprouts and radish need strong light, Toona sinensis needs medium light, and dragon beard pea has strong adaptability. Pay attention to the period of bud growth, the light can not be too strong, otherwise cellulose is formed early, affecting the quality, too weak or insufficient light is easy to make the bud weak, and lead to lodging and decay.

2. Moisture: as the sprouting vegetables are fresh and juicy, they must be watered frequently and sprayed or sprayed 2 or 3 times a day to moist the substrate in the plate without dripping a large amount of water. Spray less in rainy days or at low temperature, and spray more in high temperature and dry days.

3. Ventilation: ventilation should be maintained every day to adjust temperature and humidity.

Timely harvest

Sprouting vegetables take tender stems and leaves as products, with tender tissue and high water content, and most of them are sold in vivo. The harvest standards are as follows.

1. Dragon beard pea: the buds are light yellowish green, the seedlings are 10-12 cm high, neat, the top cotyledons are unfolded, tender and not fibrotic.

2. Toona sinensis: the buds are dark green, with a height of 8cm and 12cm, neat, cotyledons unfolded, hypertrophy, heart leaves not coming out, and rich fragrance.

3. Buckwheat sprouts: green cotyledons, red Hypocotyl, 12-15 cm high seedlings, flat cotyledons, full hypertrophy.

4. Baby tassel radish: the sprouts are emerald green, with a height of 8cm and 10cm, neat. The cotyledons are spreading and hypertrophic.
