【摘要】 防治水稻苗期恶苗病、立枯病和杂草是目前水稻有机栽培急需解决的关键技术。利用物理方法(温汤处理)和微生物技术(有机育苗生物调理剂)进行防治苗期恶苗病、立枯病和杂草控制试验,并研发了有机育苗生物调理剂。研究结果表明,温汤处理采用58℃温度处理15 min或60℃温度处理10 min,能够有效控制恶苗病和立枯病的发生;有机育苗生物调理剂具有杀灭病原菌、抑制立枯病及杂草发生,并提高秧苗素质等功能。

【Abstract】 Control of bakanae,damping-off diseases and weed at seedling stage are the key techniques of organic rice cultivation in the present.The experiment was conducted to prevent bakanae,damping-off diseases and weed through physical and micro-techniques and the bio-adjustor for organic seedling nurturing was developed.The results showed that when the seeds were treated with 58℃water in 15 min or 60℃water in 10 min,the bakanae and damping-off diseases could be controlled effectively.The bio-adjustor for organic seedling nurturing had the effect of removing pathogens and preventing the damping-off disease and weed,as well as improving the seedling quality.
