Planting methods and management points of peanut sprouts

Peanut sprout is a kind of food with both dietotherapy and therapy. it can not only be eaten raw, but also rich in nutrition, and the content of energy, protein and crude fat ranks first among all kinds of vegetables. and rich in vitamins, potassium, calcium, iron, zinc and other minerals and various amino acids and trace elements needed by the human body, with high planting prospects, let's take a look at the planting method of peanut sprouts.

Planting preparation

1. Varieties: to select small-grain peanut varieties, we should use new varieties produced in the same year with full grains, uniform size, no damage, strong germination potential and high germination rate.

2. Site: peanut sprout production requires strict temperature and humidity conditions, generally does not need light, but requires fresh and smooth air, can use free living room or waste spare room and so on.

3. Containers: foam boxes of various specifications are available, generally choose boxes with a length of 60 cm, a width of 40 cm and a height of 25 cm. The bottom of the box is required to be flat with drainage ventilation holes.

Sowing method

1. Seed selection: select new seeds of the current year, preferably small white-skinned peanut varieties, and choose seeds with full seeds, uniform size, intact seeds and more than 95% germination rate.

2. Soak the seeds: soak the selected seeds in clean water for 12 hours and 24 hours, so that the seeds can fully absorb water and expand. Then remove the seeds and rinse them with clean water for 2 or 3 times before sprouting.

3. Sprouting: the germination should be carried out in the seedling plate, and the soaked seeds should be sowed directly in the seedling plate, and then the seedling plates should be stacked on top of each other. The appropriate temperature is 22-25 ℃.

4. Sowing: the cultivation container is cleaned and sterilized, and the germinated seeds can be placed on the plate. The sowing amount of each seedling plate is about 500 grams, but it should be placed in a single layer and cannot be piled up.

Planting management

1. Weeding: after 2-3 days of sowing, when the bud is 1 cm long, all the unbudded kernels will be removed.

2. Temperature: the suitable temperature for peanut bud growth is 18-25 ℃, spraying more water to cool down in summer and strengthening heat preservation in winter.

3. Watering: watering 3-4 times a day, with clean well water as appropriate, and the amount of water should be drenched by all the shoots and soaked through the substrate.

4. Lighting: during cultivation, the room should be kept dark and invisible, otherwise the peanut buds will turn green and affect the appearance and taste.

5. Harvest: in the normal cultivation environment, it takes 7-8 days from sowing to harvest in summer and autumn, and 8-10 days in winter and spring.

Production Technology of Peanut Bud Seedling vegetable by Sand Culture

Peanut sprouts have the characteristics of crisp, tender and refreshing, rich in nutrition, is a new type of pollution-free sprouts, suitable for both young and old. The use of white foam incubator sand culture to produce peanut sprouts, especially suitable for family production, self-food, cost-effective, safe nutrition. Next, introduce the main technical points of producing peanut sprouts by sand culture.

First, select seeds

Select small-grain peanut varieties such as Tianfu No. 3 and Jihua No. 4, or black peanut varieties with higher nutritional value, requiring full nuts, uniform size, no damage, no diseases and insect pests, strong germination potential, high germination rate, and new peanut species produced in the same year.

Second, soaking seeds to accelerate germination

First soak in warm water of 50 ℃ for 1 minute, then soak in clean water for 8-10 hours, change water twice during this period, wait for the seeds to absorb water and expand, rinse with clean water twice, then put them into a woven bag or incubator made of cotton thread to accelerate germination, and sow seeds when they are white.

Third, sow seeds on the border

Pour the sand into the incubator with a thickness of more than 30 centimeters, then scrape it flat with a scraper, spread the germinated peanut seeds evenly into the border, sow densely without leaving a gap, cover with 5 centimeters of fine sand after sowing, and water thoroughly once. It is covered with black plastic film or newspaper and other objects to block light and moisturize.

IV. Seedling tray management

The moisture retention of sand is good, and generally there is no need to replenish water 2-3 days after sowing. Spray water with a spray can every 3-5 days to keep the seedling plate dark and humid. During cultivation, the incubator should be placed in a dark environment to prevent peanut buds from turning green and affecting the taste and quality. Water spraying should be carried out in a dark environment, and the cover should be covered in time after spraying water.

5. Timely harvest

When the bud grows to 8-10 cm high, the top bud valve is not unfolded, the bud can be harvested when the bud is strong, white and tender, and can be eaten after cleaning.

Planting techniques and key points of management and harvest 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.
