1, site selection Flat topography, fertile, well-drained, irrigation convenience of sandy loam plots as a nursery. In early spring when the soil is 20 centigrade, it will be topped and topped with 4,000-6,000 kg of base fertilizer per mu. 2, sowing my region generally use spring broadcast (before and after Ching Ming).垅 for the use of large 垅 double line, 垅 distance 60 cm, 30 cm 垅 surface, sow 2 lines, 15 cm spacing, spacing 10 cm, a triangle between the two on-demand.畦 for the long 10 10 meters, 畦 wide 1 meter, 25 cm spacing, plant spacing of 10 cm sow a seed. Cover soil 4-5 cm. In order to sprout neat, covering soil thickness should be uniform, the seeds should be placed flat. Before sowing enough water at the end of sowing, in general, do not irrigate before emergence
