Description
1. Variety selection: The planting varieties of black bean seedlings should choose varieties with fast germination, short growth cycle, uniform seedling thickness, strong disease resistance and good palatability. Currently, there are two varieties of black bean and flat top black that are commonly used as cattle feed. It is best to use black beans that were harvested that year.
2. Seed treatment: Before planting the black bean seedlings, firstly, the seeds are air-selected and water-bleached, and the mechanical rolling damage, insect-eaten, moldy, and too small seeds should be removed. Inferior beans, and then fish the black beans into a bamboo sieve to control the moisture.
3. Soaking seeds in warm soup: Pour the controlled black beans into warm water at 55°C for seed soaking in warm soup. Stir continuously in one direction. The amount of water used for seed soaking is twice the amount of dry seeds. When stirring for about 15 minutes, add an appropriate amount of cold water, and soak it when it is cooled to 25°C. At the same time, add a 2 ml) rootless bean sprouts. After stirring evenly, soak the seeds for 24 hours. At this time, the black beans have absorbed enough water. Wash them with clean water for 2 to 3 times, pour them into a bamboo sieve to control the water, and let them dry for 3 to 30 minutes. 5 minutes, ready to germinate.
4. Disinfection and germination: Lay a layer of toilet paper on the bottom of the sterilized foam box, spray it with warm water at 25-30°C, spread the black beans evenly in the box, and let the beans be covered with a dense layer at the bottom of the box. Use dry bean seeds for each box. 350 grams, spray with warm water at 20°C after laying. Then each 6 trays are stacked for germination.
5. Seedling stage management: During the whole production process of black bean seedlings, water should be sprayed 2-4 times a day. If the temperature is high and the humidity is small, spray more. Otherwise, spray less. spray. In addition, the moldy seeds should be removed in time to avoid causing the disease center and infecting the surrounding beans. When the foam box is reused, it should be thoroughly disinfected with rot fungus, and exposed to the sun for 3 to 4 hours.
