Production of black bean sprouts with foam plastic boxes, simple cultivation facilities, and the production of spear products without pollution, welcomed by consumers. The production site cultivation site can be either a greenhouse or an idle house or balcony. As long as it can meet the temperature, humidity, light requirements of the growth of sprouts, and there are sufficient and clean water sources. Production facilities In order to use the space effectively, it is possible to use shelf-type cultivation, and the seedling box can also be placed directly on the ground. Miao box more foam plastic boxes, specifications for 56 cm x 40 cm x 16 cm. Four holes are drilled around the seedling box to drain the excess moisture from the box. Spent waste is generally used as a cultivation substrate. Large-scale cultivation should also be installed micro-spray facilities, small-scale production of more use sprayer or high-pressure small watering can spray moisturizing. Diffuse seed before sowing, and fully dry. Wash twice with clean water and then soak in warm water of 20-30 degrees for 6-12 hours. Soaking time should be longer in winter when the temperature is low, and shorter in summer. The amount of water used is 2-3 times the seed volume. After germination soaking, gently wash off the mucus on the seed coat, then remove and drain the water, spread evenly into the foamed plastic box that has been covered with moist newspapers, and spread about 500 grams of dry seeds per box. After sowing, each of the 6 seedling boxes is tied together, and an empty box is shaded at the top and placed on the cultivation shelf or on the ground to germinate. During the germination process, the temperature is maintained at 25-30 degrees, and it is necessary to change the position up and down once a day. At the same time, spray moisture, water spray should not be too large, no water in the box is appropriate. Spray water 2-3 times a day, keeping a certain distance between each seedling box. Management after budding When the black bean sprouts grow to 2-3 cm in length, the seedling boxes should be placed in a timely manner in order to avoid bad seeds and rotting buds. (1) Lighting management. Black bean sprouts are not very strict with the light requirements. In order to make the black bean sprouts transition from dark, high temperature and high humidity germination conditions to the cultivation environment, the seedling boxes should be placed in the air temperature and humidity before moving to the production room. Stable and low-light conditions for 1 day, then let the sprouts grow under scattered light, do not let direct sunlight, so as to avoid premature emergence of fiber sprouts and quality. (2) Temperature and ventilation management. The germination phase requires a temperature of 25 to 28 degrees, and the temperature after exiting the box is 18 to 25 degrees. Heating and insulation measures should be taken in winter booths. In the hot summer season, shade nets should be installed to increase the amount of ventilation so as to keep the air in the cultivated environment fresh and reduce rotten seedlings. (3) humidity management. Spray 2-3 times a day, the amount of water spray should not be too large, in order to wet the substrate in the seedling box rather than water. The floor of the shed is also sprayed with moisture, and the relative humidity of the indoor air is maintained at about 85%. When the weather is cloudy, snow, and rain, it is necessary to spray less water. In sunny days, it is necessary to spray more when there is a drought. Reasonable disease prevention of black bean sprouts is rarely diseased, but the germination period is prone to seed mildew, and it is prone to rotten root downing during the growth period. In order to ensure that the product meets the green pollution-free food standard, the seedling box and Other utensils shall be strictly cleaned during the production process. Potassium permanganate solution having a concentration of 0.1% may be sprayed on the seedling box and the greenhouse. Found that rotten seedlings should be removed as soon as possible. 6-15 days after sowing and sowing, the cotyledons should be fully expanded. When the embryo axis length is 12-15 cm, it can be harvested or sold with a box. Source: Yuan Dongzheng, vegetable service center of Shengzhou, Shandong Province
