At this time, the temperature and humidity are suitable, the seed germination rate is the highest and the growth is the best. Before sowing, repair the soil, remove weeds and stones, and then apply sufficient base fertilizer. The propagation methods of sowing are row sowing or pull sowing, the row spacing is 30-35cm, and the planting depth is1-2cm. After sowing, the seeds are covered and squeezed.
