Radish sprout is a fatty seedling formed by the germination of radish seeds. It is also called doll radish, doll radish or shellfish. The production methods are flexible and diverse, and can be produced using various facilities. For example, solar greenhouses and improved Yangshuo can be used for production in winter, and shade nets can be used for production in summer. Farmers can use idle houses and idle land for production. Town residents can make use of balconies, house aisles and other production. If properly cultivated, 1 kg of radish seeds can produce 10 kg of radish sprouts, 1 square meter can produce 5 kg of sprouts, high input-output ratio, and can achieve higher economic benefits. First, the choice of species: the best selection of green varieties of the epidermis, and pay attention to screening suitable for growth at different temperatures. Stem white or light green, dark green or light green leaves, thick and shiny embryo axis, large amount of seeds, high germination rate is good, such as Daqing radish, Mid-Red, dry ideal. Seeds should be full of grain and strong in life. Thousand grains weigh more than 15g, and the germination rate should reach more than 80% within 48h (hours). Second, seed treatment: seeds first sun in the sun, placed in 30 °C water immersion 10min (minutes), and then with 52 °C water immersion 15min (minutes), and then immersed in water at room temperature for 3h (hours). Remove it, wrap it in gauze, or put it in a damp cloth, germinate at a temperature of 20 to 25°C, and sow when 50% of the seed is white. It can also soak in seeds with 0.2% bleaching solution for 1 minute (minutes) before sowing, germination after sterilization, or slightly dry to sow. Third, the production method 1, the traditional production method: From November to March the following year, it is produced in a plastic greenhouse or modified Yangshuo. The high temperature period must be shaded and ventilated, and attention should be paid to heat preservation at low temperatures It is best to use sand culture method. The production site will be leveled, with bricks 1 meter wide, unlimited seedbeds, seedbeds with fine sand, 10 cm thick, and the sand bed will be sprayed with warm water and sowed. When sowing, mix the soaked seeds with 2 times the amount of dry fine sand and spread them evenly. If there are piles, you can use a straw stick to spread it evenly. Generally about 200 square meters sowing about 200 meters, sowing cover fine sand, thick 1.5 cm, and then cover the film insulation moisture. It can also be cultivated in soil, but the soil should be loose and fertile, and a small amount of nitrogen fertilizer should be added. The surface should be leveled and the bottom water should be poured. One square meter is broadcasted with 120-250g seeds, covered with fine soil or fine sand, 1.0-1.5cm thick, covered with straw screens, or newspapers, or black shade nets. Early and late water spray, temperature maintained at 15-20 °C, 3-4d (days) emergence. At this time, it is necessary to promptly remove the cover, spray water, spread the arched sand cover or soil, and help the seedlings unearthed. After emergence, visible light grows. If the sunlight is strong, cover it with a black shade net. When the seedling height is 3-5 cm, pour 0.5% nitrogen fertilizer water. Afterwards, use dry eyes to spray water sooner or later when dry. Sprinkle water should not be too much to prevent the occurrence of damping-off. Nor can it be too dry, otherwise the seedlings will age and the quality will be poor. 3 days before harvest (days), when the shoot length was 5 cm, the cover was removed and the greening was promoted under weak light. In this way, the hypocotyls of the seedlings are erect, with pure white color and good quality. Can also be sowed once after the cover of soil, 8-10 cm thick, or sub-cladding, so that seedlings shade softening, immediately after unearthing harvest, green under the white, better quality. When the radish sprouts cotyledon flattened, the true leaves did not emerge, and when the roots were white and tender, when the morning dew did not dry or when the sun was setting in the evening, the roots were uprooted and 400-500 g were bundled and listed. 2, hydroponic production method (1) Factory production. The use of idle residential or light industrial plants as production sites, sub-nursery room, green room, studio and so on. The wall around the nursery room is painted black to reduce indoor lighting. The relative humidity of the air is 60%-90% and the temperature is 20-25°C. The afforestation room is where the seedling shoots grow 10-12 centimeters long and is cultivated by light. It is usually located on the sunny side. It is installed with a large glass window and the surrounding walls are painted white. The indoor light intensity is 3000 lx (lux) and the relative humidity is 60%. 85%, temperature 16-25°C. The studio is used for soaking, sowing and sprout packing. Three-dimensional cultivation of radish sprout production. The cultivation frame was welded with angle iron. Except for the ground floor 10 centimeters away from the ground, the remaining layers were separated by 40 centimeters. Each cultivation shelf is placed with 6 cultivation trays. There are 4 small wheels at the bottom of the rack. There are 2 directional wheels, which can be moved freely in the room. The distance between each rack is 50 cm for the staff to operate. In order to facilitate the sale of living products, a product concentrating rack should also be set up, with a spacing of 22 centimeters per floor, and supporting the size and transportation work. For transport on bicycles, pallets on both sides of the bicycle are used to hold the cultivation trays. Each side has a cultivation tray with 5 floors. When transporting by car, 6 cultivation trays can be placed on each floor. Lightweight plastic vegetable seedling tray for cultivation containers, 58.4 cm in outer diameter, 24.2 cm in width, 6.1 cm in height, 57.2 cm in inner diameter, 22 cm in width, 5 cm in height, and 3 mm square holes in the bottom of the pan, arranged approximately neatly. It is 1.2 mesh/cm2. Drape Pack,Vertical Drape Pack,Disposable Drape Pack,Disposable Medical Drape Pack ShaoXing SurgeCare Medical Products Co., Ltd. , https://www.sxsurgecaremedical.com
