Cultivation of radish sprouts, indoors and protected areas. The following small series will introduce the cultivation method of radish sprouts.
Agricultural techniques prefer seeds. For the seeds used to cultivate radish sprouts, radish varieties with excellent growth potential, strong disease resistance and good quality should be selected. Such as Dahongpao, green fat radish, and heart red.
Soaking seeds and germination. Wash the radish seeds first, then soak for 8-10 hours at room temperature with 3 times more water than the seeds (during the period, rinse the seeds 1-2 times with running water, each time to clarify to the degree), then The seeds were germinated under conditions of 23-26 °C. When the seed is exposed to the embryo at 3-5 mm, it can be sown.
Seeding method. Seedling trays and seedbeds can be sown. The seedling tray requires a flat bottom surface, is sturdy and durable, and has good permeability; the cultivation substrate can be made of white cotton cloth or wrapping paper. Before seeding, the seedling trays are cleaned, disinfected, and then coated with a layer of cultivation substrate, and then the seeds are evenly sprinkled on the substrate in the seedling tray (100-150 grams per tray). After planting the seeds, place the seedling tray on the cultivation rack. The seedbed should choose loose, fertile and well-drained sandy loam blocks. Water should be poured before sowing, and then the seeds should be evenly spread on the seedbed by seeding (150-250 grams per square meter). After sowing the seed, cover a layer of 1 cm thick loose soil.
Seedling management. Mainly pay attention to the reasonable regulation and ventilation of temperature and light to ensure the yield and quality of sprouts. The growth temperature at the seedling stage should be controlled at 20-25 °C. When ventilation is cooled, care should be taken not to allow the wind to blow directly onto the sprouts. If the seedling tray is sown, it should be dumped once a day (upper and lower, back and forth) to make the buds receive the same light and grow neatly. The requirement for humidity is: use the seedling tray to sow, keep the medium in the tray moist but not collect water. The indoor air humidity should be controlled at about 80% (can be adjusted by spraying or spraying). When seedlings are planted in seedbeds, the water can be watered when the seedlings grow to 3 cm in length, and attention should be paid to the use of small water to avoid rotten seedlings.
Harvested at the right time. When the seedling tray is cultivated, when the radish sprouts grow to more than 1 cm, they can be sold in a whole plate, and the tray can be recycled and reused. When the seedling bed is cultivated, when the sprouting seedlings are emerald green, the seedling height is 8-10 cm, and the cotyledons are flat, fully enlarged, and can be harvested when there is a matchstick.
