采用杀菌剂浸种可以杀灭水稻恶苗病病菌,但同时会不同程度地影响种子萌发和秧苗素质。通过试验发现,无论从种子萌发还是幼苗生长来看,以水引发技术为基础的“两段浸种法”可以大大提高早稻种子对杀菌剂抑制生长作用的抗性。
The fungicides are widely applied on the management of rice bakanae disease, but rice seed germination and seedling biomass are inhibited by the fungicides. The results of this study indicated that two-phase soaking method, which was based on seed priming, improved the seed germination rate and seedling resistance to the fungicides. Meanwhile, the results revealed the on-farm application potential of the method.
