Put the foam box on the bracket or on the ground, take a rootless bean sprouting (2 ml) and water 1-2 kg, spray the seedlings to reduce the production of lateral roots and root hairs, and increase the cotyledon area.

2. When the black bean seedling is 8-9 cm high, take a thickening agent (2 ml) and mix it with water 1-1.5 kg, spray the bud seedling to restrain the true leaf elongation, make the stem thicker and become brittle and tender, reduce the fiber content and make the bean flap fat, bright green and glossy, and the merchandise is improved.

3. Black bean seedlings are sprayed 2-4 times a day in the whole production process. If the temperature is high and humidity is small, then spray less, spray less in the early growth stage, grow rapidly in the later stage, and need more water, so you should spray more.

4. The moldy seeds should be removed in time in the production of black bean seedlings, so as not to cause the disease center and infect the surrounding bean seeds. When the foam box is reused, it should be thoroughly disinfected with rotten fungus and exposed to the sun for 3-4 hours.
