A, selected seeds. Seeds for sprout cultivation, should pay attention to the selection of germination rate of more than 95%, purity, purity are high, full of seeds, without any contamination of the new seeds.
Two, soak the seeds to promote germination. After selecting the seeds, generally choose 20 ~ 30 ℃ of clean water amalgamated 2 ~ 3 times, and then more than 2 ~ 3 times the volume of seeds soaked in water. Winter time is slightly longer, summer time is slightly shorter, generally peas 18 to 24 hours, 12 to 20 hours, buckwheat 24 to 36 hours, radish 6 to 8 hours. The end of soaking, rubbing off the seed coat mucus, fishing out and draining the excess water from the seed surface, the seeds in a flat-bottomed container, covered with a wet towel or wet sack piece, peas placed in the 18-22 ℃, radish, buckwheat placed in the 23-26 ℃, toon placed in the 20-23 ℃ at a constant temperature for germination. Peas, buckwheat, toon after 48 hours, radish 24 hours, seed buds up to 3 millimeters long can be sown.
Three, fine sowing. First rinse the sowing tray, the bottom of the tray 1 to 2 layers of white paper (or old newspapers), the paper to absorb enough water, then, the seeds have been germinated evenly spread on the wet substrate, generally 60 × 25 × 5 cm size of the sowing tray, the amount of seed sown per tray: peas for 350 to 400 grams, buckwheat 150 to 170 grams, 80 to 100 grams of radish, toon 30 to 50 grams. After sowing, and then the seedling plate neatly stacked together, covered with black plastic film, peas at 18 ~ 23 ℃, buckwheat, radish 20 ~ 25 ℃, parsnip 20 ~ 23 ℃ temperature under the "stacked plate germination." 2 days after the buds as high as 2 to 3 cm, you can seedling tray "on the shelf", and at this temperature began to see the light growth.
