Black bean sprouts production technology
Black bean sprouts (small bean sprouts) are a kind of tender and nutritious sprouts. Rich in calcium, phosphorus, iron, potassium and other minerals and a variety of vitamins, the content is higher than the green bean sprouts. Generally eaten when the shoot height is 3-10 cm. At this time two true leaves have not yet been unfolded, can be fried, soup or salad and hot pot vegetables, taste crisp and crisp, unique flavor, excellent taste. 1. Production conditions are carried out in shady sheds or cool rooms in summer and in greenhouses or indoors in winter. Black bean sprouts have a short production cycle and can be harvested in about 10 days. The trays for three-dimensional cultivation can be made of angle iron and wood, and the size depends on the space. In general, the spacing between each layer is 40 cm, so that the lower layer of sprouts has light. Seedling tray can be used plastic seedling tray, flat bottom vent. 2. The use of new species of black adzuki bean used in the production technology requires a germination rate of more than 90%. The clean seeds were picked and soaked in warm water at 20°C for 36 hours to allow the seeds to absorb enough water to germinate. Sowing without any agricultural fertilizer, the newsprint paper with strong water absorbency can be placed on the seedling plate, and the seeds can be evenly spread on the plate after being moistened with water. Each dish is used in O. 25 kilograms or so. Then put the seedlings stacked, generally 5-10 as a stack, the top layer of moisturizing with wet sacks. The room temperature is kept at about 22°C. It can be as long as about 1cm in two or three days. At this time, it can be put on shelves separately and sprayed 3 times a day to keep the paper tray moist and water free. At 20°C, it can be harvested after about a week or 7-8 cm in length.
