Hydroponic Cultivation Process of Barley Fodder

Pre-preparation

Venue

1. Light-sheltered area, low-light area, natural light, strong light area

2. Workshop selection is relatively free: private houses, boarding houses, sheds, office buildings, containers are available.

3. Requirements for the workshop device temperature control equipment, such as air conditioning, exhaust fans, water heating, boilers and automatic temperature control equipment.4. The workshop can also be structured with sprinkler system, according to their own requirements.

5. The workshop needs to do a good job of waterproof coating to prevent moldy floors, it is necessary to install automatic sterilization devices or daily with a sprayer to eliminate.6. Lighting device red and blue light belt and LED plant white light belt.

The nursery frame

Height: 10-15cm from the ground, each layer spacing 35cm or so.

Length: according to the size of the plate, generally can put 6-10 plates.

Width: according to the length of the plate (generally divided into 56cm and 59cm, but there are other specifications), can be smooth against the plate, the bottom of the shelf to do a good job of drainage prevention.

Seedling tray and water catching tray

Standard seedling tray 59cm * 24cm * 4cm and 56cm * 24cm * 3cm bottom must be with holes. Water catching tray can be the right size, there is no fixed requirements.

Water spraying equipment

Spray cans, sprayers, automatic watering equipment (electric sprayer, water pump, submersible pump, pressure pump)

Seedling paper

Requirements for good water absorption, size according to the inner diameter of the plate to buy.

Note: Try not to choose newspaper, newspaper has ink containing lead is higher.

Pool or bucket

1. Sterilization pool (bucket)

2. Soak seed ground (barrel)

3. Water storage tank (bucket)

Thermo-hygrometer (at least two or more in a separate room)

Shade curtains and light strips

It is necessary to install plant LED red and blue light and LED white light strip, red and blue light strip is used during the sprouting period, white light strip is used during the growing period.

Planting process of barley seedlings

Seed Selection

1. Purchase fresh and full seeds of the year with high germination rate;

2. Purchase seed attention to the principles: particle size as uniform as possible, bright color, high purity, high germination rate;

3. Selection of seeds: remove impurities and cracked seeds, eliminate insect-infested, mutilated, moldy, deformed and especially small seeds;

4. After selecting the seeds, use tap water to wash the soil and other attached impurities on the surface of the seeds.

Soak the seeds

1. Use disinfectant powder (1g to 500ml water ratio) to kill the seeds for one minute before soaking. Indoor seed soaking, cold water soaking.

2. Seed soaking time: 12-18 hours in winter, 8-12 hours in summer.

3. The amount of water used for seed soaking should be more than 3 times that of the seed, and it is better to have more than less, and the water used for seed soaking should not be reused.

4. Seed soaking end judgment standards: a seed bud mouth bulging b hand pinch seed cross-section, very brittle and easy to pinch off.

5. Fish out the seeds after the end of soaking, and use sterilized water to clean off the mucus on the surface of the seeds.

Germination, constant temperature germination

1. Rinse the soaked seeds with sterilized water and put them into the germination basket.

2. The amount of seeds in the basket is best not more than two-thirds of the capacity of the germination basket (to avoid uneven heat, affecting the germination of seeds), and then put into the germination room.

3. Germination time 14-16 hours, water spray 3-5 times intermittently, the seed buds should not be too long, 80% of the seeds can be divided into disks.

4. Nutrient solution use: first of all, according to the ratio of 1:1000 dilution, for the later daily spraying sprouts use.

Dividing Plate

1. Good sprouting seeds cleaned with water, the seeds evenly spread to the seedling tray, generally large seeds accounted for about 90% -95% of the bottom of the plate, small seeds spread evenly density of 90%; due to high temperatures and high humidity sprouts are prone to rot. Small trays must be covered with planting paper: leak-proof, moisturizing.

2. Light-sheltered area: top covered with the same seedling tray stacked tray shading growth (about 2 days)

3. Stacked trays need to be watered 1-2 times a day by inverting the tray.

4. Sterilize with red and blue light strips for supplemental light, 3-6H per day is sufficient.

Cultivation

1. Temperature: the growth of sprouts at 20-25 ℃, the lowest can not be lower than 18 ℃, the highest can not be higher than 30 ℃.

2. Humidity: the relative humidity in the workshop is 5-70%.

3.Watering

Sheltered area, once a day in winter, 2-3 times a day in summer, according to the actual situation (large seeds with spray water, small particles of seeds with atomized water), as long as to ensure that the seed coat is moist, the planting paper is moist, and no water storage.

Supplemental light treatment: white light of the light is most suitable for growth, daily light length 6-12H, to supplement the missing light time, to achieve the effect of wheat seedlings to increase yields and reduce disease.

After on the shelf, due to the root cross, poor water permeability, watering should be small water, to ensure that the roots are moist.

4. Ventilation: 1-2 times a day in winter (choose when the highest temperature of the day); 2-3 times a day in summer (avoid the highest temperature of the day). Ensure fresh air in the workshop.

5. Cooling measures: a spray to increase the relative humidity of the workshop; b increase the number of ventilation; c shade (shade net); d water air conditioning (not recommended, the cost is too high).

6. Light: the whole growth process of sprouts do not need strong direct light, low light (window light can be). LED white fill light (special fill light).

Harvesting

The general harvesting height of sprouts in 15-20cm, barley seedlings grow too old low nutrient content.

Sterilization

According to the different disinfection objects are divided into 3 kinds:

Disinfection of disinfectant powder

Mainly for the disinfection of plant, cultivation frame, seed dipping pool, seedling tray, after blending into water to become colorless can be.

1. Disinfection of plant, cultivation frame: before planting, spray with 84 disinfectant solution, sealed for half a day, ventilated and then used.

2. Disinfection of seed-soaking pool: after seed-soaking, pour out the water, flush with disinfectant powder solution and rinse with clean water (once a week).

3. Disinfection of seedling trays: no matter new trays or reused old trays, soak them in disinfectant powder solution for 15 minutes, and rinse them with clean water (disinfect them once a week).

Sterilization (focus on attention during planting)

Mainly for water, germination box, planting process workshop disinfection.

1. Sterilization powder use: a gram to a catty of water, a spoonful of 10g to 10 kg of water

The first step before soaking the seeds into the disinfectant water to soak 1-2 minutes, fish out and directly soak the seeds.

Step 2 Spray about 12 hours after germination

Step 3 Spray once after spreading the disk, then dry and put into the box production

2. Sterilization of germination box (use 84 disinfectant)

3. Dilute according to the instructions on the bottle of disinfectant solution, disinfection of the workshop during the planting process

Single variety rot, find the cause of the seed; you can selectively use preservatives; multiple varieties of rot, disinfect the workshop.

Seal the workshop, people are forbidden to be inside during the disinfection period, and enter after ventilation.

Mainly for seed soaking bags, germination bags, work clothes disinfection. Concentration is the same as usual when washing clothes, soak the seed soaking bag, germination bag, work clothes in 84 solution for 15 minutes, rinse with water, dry, sun dry and use.

Precautions:

How to deal with the cause of root yellowing:

1. temperature control within the wheat seedlings suitable temperature, the temperature is not higher than the maximum 28 ℃, some varieties do not exceed 26 ℃.

2. Problems caused by bacterial infection, sterilize with disinfectant powder (disinfectant powder ratio: 1 gram to 1 pound of water, spray the roots, once a day);

3. Indoor sterilization, with 84 disinfectant solution at least 2-3 times a day, ground wall spraying.
