This is done in a shaded or cool room in the summer and in a greenhouse or indoor in the winter. Black bean sprouts production cycle is short, about 10 days can be harvested. Three-dimensional cultivation with the disk frame can be made of angle iron, wood, size space dependent. Generally each layer is spaced at 40 centimeters, so that the lower layer of sprouts have light. Seedling tray available plastic seedling tray, the bottom of the flat with exhaust holes.

Production technology

The black small beans used must be new seeds, germination rate higher than 90%.

The selected clean seeds are placed in warm water at 20 ℃ to soak for 36 hours, so that the seeds absorb enough water for germination. Sowing without any agricultural fertilizer, you can use the more absorbent newsprint in the seedling tray, water to wet the paper can be evenly spread the seeds in the tray. The amount of seed used per tray is about 0.25 kilograms. Multi-faceted hands will be seedling tray stacked, generally 5-10 trays as a stack, the top layer of wet sacks to keep warm. Room temperature is maintained at about 22 ℃, two or three days can grow to about 1 cm, at this time can be separated on the shelves, spray water three times a day to keep the paper plate inside the moist and not waterlogged. In 20 ℃ conditions, a week or so length of 8 cm long can be harvested.
