Cultivation techniques of sprouts
Bean sprouts are eaten by young organs of plants. Sprouts are tender, delicious and unique in flavor, and have rich nutritional value and dietotherapy function. In the process of cultivation, the seed pollution is less, the growth speed is fast, the environmental conditions are easy to control, the growth cycle is short, and the production and economic benefits are high.
I. Planting facilities
1. cultivation frame: made of angle iron, steel bars, bamboo and other materials, which is conducive to multi-layer three-dimensional cultivation. Generally, there are 3-5 layers of cultivation racks with a spacing of 30-40 cm, and the width depends on the length of the seedbed. For convenience of operation, the height shall not exceed1.6m..
2. Cultivation containers and substrates: containers are generally made of light plastic seedling trays, and the specifications are 60 cm long, 25 cm wide and 5 cm high. The base material is mostly white paper (old newspaper), but also white cotton cloth, non-woven fabric, 3 mm thick polyethylene foam board, perlite or river sand.
3. Water spraying facilities: In order to ensure the requirement of water for the growth of dental seedlings, it is necessary to keep the substrate moist, strengthen spraying and keep the air humidity. Micro-spraying facilities should be installed for large-scale planting, and sprayers and watering cans should be equipped for small-scale planting.
Second, be technical. At present, the most popular sprouts in the market are pea tooth vegetables, followed by radish, Toona sinensis, buckwheat and other sprouts, and their cultivation points are basically the same.
1. Seed selection: New seeds with germination rate above 95%, high purity and cleanliness, full seeds and no pollution should be selected. In particular, the seeds of Toona sinensis are easy to lose their germination ability under high temperature conditions, and more attention should be paid to selecting new seeds that have not passed the summer (wear off their wings before use). Cultivating sprouts with such seeds has the advantages of fast growth, strong growth, slow fiber formation, low yield, tender quality and no pollution.
2. Soaking seeds to accelerate germination: wash the selected seeds with clean water at 20-30℃ for 2-3 times, and then soak them with water 2-3 times the volume of the seeds. It's longer in winter and shorter in summer. Generally speaking, pea 18-24 hours, Toona sinensis 12-20 hours, buckwheat 24-36 hours and radish 6-8 hours. After soaking the seeds, wipe off the seed coat mucus, drain the excess water, put the seeds in a flat-bottomed container, cover them with a wet towel, put the peas at 18-22℃, and put the Toona sinensis at 20-23℃ at constant temperature to accelerate germination. Peas, buckwheat and Toona sinensis can be sown after 48 hours, and radishes can be sown after 24 hours, when the buds are 2-3 mm long.
3. Sowing: Wash the seeding tray, lay 1-2 layers of white paper (or old newspaper) on the bottom of the tray to make the paper absorb enough water, and evenly spread the germinated seeds on the wet substrate, generally 60? 25? 5 cm tray, the sowing amount of each tray is 350-400g of peas, 0/50-/0/70g of buckwheat, 80-/0/00g of radish and 30-50g of Toona sinensis. After sowing, the seedling trays are neatly stacked together and covered with black plastic film, peas 65438+. Laminating to accelerate germination? Two days later, when the buds grow to 2-3 cm high, you can put the seedling tray on the shelf and start to grow under the light at this temperature.
4. Bud management: ① illumination. Buckwheat buds and radish buds need strong light, Toona sinensis seedlings need medium light, and asparagus peas have strong adaptability. It should be noted that the light should not be too strong during the growth of sprouts, otherwise cellulose will form prematurely and affect the quality; If the light is too weak or insufficient, it is easy to make the sprouts thin, leading to lodging and rot. 2 moisture. Because the sprouted vegetables are tender and juicy, they must be regularly supplemented and sprayed 2-3 times a day, subject to the fact that the substrate in the vegetables is moist and does not drip a lot. Spray less when it is rainy or the temperature is low, and spray more when it is hot and dry. ③ Ventilation. Keep ventilation and adjust the temperature and humidity every day.
5. Harvest: tender stems and leaves are the products of sprouted vegetables, with tender tissues and high water content, and most of them are sold as a whole. The harvest criteria are as follows. (1) Longxu pea: The sprouts are light yellow and green, with a height of 10- 12 cm, neat, with cotyledon tips spreading out, tender and without fibrosis. ⑵ Toona sinensis after sowing: The sprout is dark green, 8-65438 0 2 cm high, neat, with spread cotyledons, hypertrophy and rich fragrance. ⑶ Buckwheat sprouts: green cotyledons, red hypocotyls and seedling height 12- 15cm. Neat, cotyledons spread out, completely hypertrophy. (4) Baby tassel radish: The sprouts are green, 8- 10 cm high and neat. Cotyledons are flat and hypertrophy.
Simple version of family sprout cultivation method
(l) Wash beans or seeds and soak them in a wide-mouth glass bottle (colored glass is better) for four to ten hours (depending on the weather and different seeds, usually the smaller the seeds, the shorter the soaking time. ) The volume of seeds in glass bottles shall not exceed 10%.
(2) Tie a piece of gauze or nylon net on the bottle mouth with a rubber band, and pour out all the water until it doesn't drip.
3) Invert the bottle to 45 degrees and put it in a cool and ventilated place. Pour water two or four times a day and soak for one or two seconds is enough. Pour water until it stops dripping, and then put it back.
(4) Edible after about 4-7 days (depending on the weather and different seeds).
Examples of cultivation methods of home sprouts
Tools/raw materials
All kinds of vegetable seeds, watering can, rice paper, seedling tray, carton.
Methods/steps
1. Buy all kinds of seeds I like. Because it is the first time to plant sprouts, I bought 12 seeds to try and see which sprouts are delicious.
2. Put the seeds in a container that can be cut off, or one cup at a time. Then pour warm water to soak the seeds. I soaked them for 24 hours.
3. Pour the placed tap water (excluding hypochlorous acid) into the seedling tray, spread rice paper on it, and spray it with a watering can.
4. put all kinds of seeds in, one piece of each kind.
5. After putting the seeds, cover them with a piece of rice paper and spray them wet.
6. Change the water in the dish once a day, spray the seeds 2-3 times a day and ventilate them 2-3 times a day.
7. When the sprouts grow to 2 cm, remove the surface rice paper and replace it with a carton with air holes.
8. When Xin Wei grows to 10 cm, remove the carton and receive scattered light.
9. According to the situation, you can cut and eat at any time and grow your own sprouts.

Matters needing attention
The seedling tray can be replaced by your own oil drum and bucket, but it should be brushed clean.
Don't use newspapers instead of rice paper, because newspapers have some harmful substances in the printing process, which will be absorbed by seeds.
The water in the tray should be changed every day so that the sprouts can grow well.
Don't let the bean sprouts receive direct sunlight.
How to plant Toona sinensis buds
1, seed rubbing: rub the seeds of Toona sinensis directly by hand, and it is easy to shed the membrane and remove the wing membrane of the seeds.
2. Seed soaking: blanch the seeds with 50-55 degree hot water for 5 minutes, and keep stirring until the water temperature reaches room temperature, and rinse for several times. Soak 10- 15 hours in summer and 20-24 hours in winter. When soaking seeds, it is best to wash them with room temperature water several times until the seeds fully absorb water and swell.
3. Germination: germinate the soaked seeds in gauze and wash them with warm water twice a day. The buds will germinate in about 3-5 days, and 40% of the seeds can be planted in the seedling tray when they germinate.
4. Put two layers of good toilet paper or gauze on the seedling tray, spread seeds evenly, and do not accumulate water on the seedling tray. Cover the tray with a clean wet towel to moisturize, or put on a plastic bag to moisturize. Plastic bags should be left with gaps, the temperature is about 20-30 degrees and the humidity is about 50-75 degrees. Spray water twice a day to let the seeds breathe freely. The height of 3-5 days seedlings is about 2cm. At this time, you can see the light and continue to moisturize and keep warm.
5. Spray it with a watering can 2-3 times a day, and the water needs to be poured thoroughly, otherwise the seedlings will dry up easily.
6. The seedlings grow to 5? 6 cm, reduce direct sunlight, seedlings 7? 8 cm, increase the light, the leaves are green and flat, fully enlarged, and the real leaves have not yet grown, so they can be harvested.
Toona sinensis bud is a high-grade vegetable, which is not only rich in flavor, nutrition and delicious, but also has high nutritional value and medicinal dietotherapy value. It has the effects of stimulating appetite and regulating human endocrine. It's a high-class feature. Can be used as main ingredients, spices, condiments, side dishes, scrambled eggs, cold salad, fried, pickled and so on. Often used to mix tofu or wrap jiaozi and cook the meat. There are dozens of ways to eat, and they can also be used as dozens of dishes.
I often make jiaozi, stir-fry, cold tofu and scrambled eggs, all of which are delicious.
Toona sinensis seedlings had better use plastic to make a small greenhouse, and the frame of the picture is surrounded by plastic to keep moisture and heat.
