In order to solve the problem of difficult germination of Sosa Japonica seeds, the Lanyin Ⅲ and Qingdao Zoysia were treated with mechanical methods, chemically by a variety of agents. It was found that Zoysia Japonica seed germination can be promoted by immersing with H 2SO 4,H 2O 2,GA 3,and dipping the seeds in NaOH and KOH solution of 7%-10% concentration for 15min could increase the rate of germination rapidly. By the comprehensive treatments (NaOH+GA 3,NaOH+ethylene) could be improved the germin...
