1.1 Seed beet sprouts

Using the nutrients stored in the seeds to directly cultivate young vegetables such as: soybean sprouts, broad bean sprouts, toon sprouts, peanut sprouts, radish sprouts, longbeard pea sprouts, mung bean sprouts and so on.

1.2 Body Vegetable Sprouts

Sprout balls, shoots, young stems, etc. cultivated using nutrients accumulated in the persistent roots, fleshy taproots, stem roots or branches of biennial or perennial crops such as: chicory sprouts, bitter vegetable sprouts, ginger sprouts, asparagus, dandelion sprouts and so on.

2 Sprouts Cultivation System

2.1 Sprouting Room and Cultivation Room

2.1.1 Selection of Cultivation Room

Plastic greenhouses, greenhouses and other facilities can be used in the winter, early spring and late fall to bunch the time tone, and can also be utilized in factories or unused houses. When the average temperature is greater than 18 ℃, can be open-air production, need to use shade net shade.

2.1.2 Temperature

The temperature of the germination room is 20 to 25 ℃, relative humidity of about 90%; the temperature of the cultivation room is more than 20 ℃ during the day, and the night is not less than 16 ℃, to avoid a big change in temperature difference. Cultivation room relative humidity control at about 85%. Pay attention to the appropriate ventilation of the room to maintain the appropriate temperature and fresh air.

2.1.3 Light conditions

The germination room should be kept in darkness or low light, and the cultivation room should be equipped with shading facilities under strong light conditions in summer and fall. Room as a production room, the requirements of north-south, east-west extension (north-south width should be less than 20m), surrounded by light, window area of more than 30% of the perimeter wall. Winter low-light season near the south wall lighting area light intensity of not less than 5000lux, near the north window lighting area of not less than 1000lux, the central area of not less than 200lux.

2.1.4 Water

With running water, storage tanks or standby tanks, etc.. The ground should be waterproof and leak-proof, and a drainage system.

2.1.5 Auxiliary

Including seed storage, sowing operation area, hole tray cleaning area, product processing area and other facilities.

2.2 Cultivation frame

Stereoscopic cultivation *** 4 to 6 layers, the first layer is not less than 10cm from the ground, the layer spacing 40 to 50cm, every two frames and put in a row, the row spacing of 50 to 80cm, in order to facilitate the operation.

2.3 Cultivation containers

Vegetable seedling trays, specifications for the 60cm × 24cm.

2.4 Cultivation substrate

Choose clean, lightweight, non-toxic, absorbent and strong water holding capacity, easy to dispose of the residue after use of the material, such as: paper, white cotton, non-woven cloth, perlite, Styrofoam sheets and so on.

2.5 Spray system

Backpack sprayer can be.

3 Bud Light Cultivation Technology

3.1 Sterilization of shed and production tools

Sterilization of the shed is often used to fumigate with fumigants to reduce the humidity in the shed. With 22% dichlorvos fumigant 500g/667m2 plus 45% Chlorothalonil fumigant 250g/667m2, dark fire ignition, fumigation disinfection or directly with sulfur powder closed fumigation, but also in the cultivation of the interior of the shed sprinkled with quicklime disinfection. Pay attention to the disinfection period should not be carried out during the production of sprouts. In addition, according to the size of the greenhouse area, set up a few appropriate disinfection lamps, before cultivation, turn on the lamp irradiation 30min, sterilization. Before sowing, the cultivation container should be cleaned and sterilized, and it can be soaked in 5% formalin solution or 3% lime water solution or 0.1% bleach water solution for 15min, and then taken out and cleaned. The cultivation substrate should be boiled at high temperature or exposed to strong light to sterilize.

3.2 Seed treatment

Selected seeds are uniformly full, thick seed coat, high germination rate, no damage to the seeds, turn the sun for 1 to 2 d. Soak the seeds in warm water at 55-60 ℃ for 10 to 15min, or 3% lime solution can be used to soak the seeds for 45-60min or 0.1% bleaching powder solution, stirring for 10min and then fish out, and then pull out and wash it with water for 2 to 3 times to remove the mucus on the surface of the seeds. Remove the mucus on the surface of the seed.

3.3 Sowing on the plate, germination

Seedling plate laying newsprint, sowing seeds, require uniform sowing, seeds do not have the phenomenon of accumulation. After sowing sprayed 1 time, and covered with plastic film to moisturize, placed on the shelf in the germination room, turning the seeds 1 time a day, watering 1 time, and changing the location of the seedling tray. When the vast majority of the seeds show buds, use the decontaminated tweezers to remove the seeds of the defeated buds, rotten buds, wounded buds and dead seeds. Germination in the appropriate temperature of 18 ~ 22 ℃ 2 ~ 3 d. Sprouts 1.5 ~ 3cm, moved into the cultivation room.

3.4 Cultivation room management

3.4.1 Watering

Keep the buds moist throughout the growth period. In the early stage of growth, drench 2-3 times a day; in the middle and late stage of growth, increase the amount of watering, drench 3-4 times a day. The amount of water in each shower to the degree that the substrate is wet, can not make the bottom of the cultivation disk has water, so as not to cause rotting seedlings.

3.4.2 Temperature

The appropriate temperature for growth is about 20 ℃, 12 ~ 30 ℃ can grow, generally controlled at 19 ~ 23 ℃.

3.4.3 Light

Seedlings grow rapidly and are not easily standardized under dark conditions. Keep the cultivation room in diffused light until harvest and shade it in summer.

3.4.4 Greening

When the sprouts are 4 to 5 cm long, remove the top cover and let them see light and green.

4 Harvest

Requirements sprout green, seedling height of about 10cm, the top leaves unfolded, the stem end of 8 to 10cm has not yet been fibrous, the general sales length of 8cm, the high temperature season of 7 to 10d, the low temperature season of 10 to 20d can be 1 crop
