Why should rice seeds be sun-dried before sowing?
Sun-drying rice seeds before sowing can effectively improve the germination rate and germination vigor of the seeds. The main reasons are: 1. Sun-drying seeds can promote after-ripening of the seeds and increase enzyme activity. After rice seeds are harvested, although they are sun-dried, winnowed and cleaned before being stored, because maturity and dryness vary, the air humidity and temperature during storage will also change. If the seeds absorb moisture, respiration becomes vigorous, and nutrients inside the seeds are consumed heavily, which often leads to weakened germination ability and reduced germination vigor. Sun-drying the seeds can enhance the permeability of the seed coat, so that they absorb water evenly during soaking and enzyme activity is increased.
