The seed germination rate was more than 90% square meters per gram of seed 6-8 (which can be planted 1 acres of field), seeding rate is about 80 g / mu (can be transplanting 3-5 acres, planting 90-120 mu). No water and cover soil after sowing. Then the bed is covered 20-30 cm high scaffolding, covered with nylon film, moisture, insulation and prevent the rain washed away the seeds.
