摘要
水稻苗期恶苗病和立枯病是目前水稻有机栽培急需解决的苗期两大病害,目前国内还没有有效可行的解决办法,有关研究文献也很少。本研究在不使用农药、化肥及育苗调理剂条件下,利用物理方法(温汤处理)和有效微生物制剂(EM)进行防治苗期立枯病和恶苗病的试验。研究结果表明:①从种子发芽率、防治立枯病和恶苗病等因素综合考虑,采用温汤56℃处理10～15 min,58℃处理10 min较安全,即不影响发芽率又能达到防病效果;②EM活性液50～150倍液和EM稀释液500倍液具有促进秧苗的生长发育和防治立枯病的作用。
Rice bakanae disease and rice seeding blight are major diseases to be solved urgently under organic culture. At present there is no effective method to control these diseases in china. There are less related research references. Under no pesticide, chemical fertilizer and nursery soil conditioner, the experiment was conducted by using physical method （hot water treatment） and EM. The results showed that it was safe for seeds treatment with 56℃ hot water for 10-15 minutes or 58℃ hot water for 10 minutes. This treatment had not affected germination and had effect on controlling of diseases. EM activated solution 50-150X and EM solution 500X have effect on increasing seedling growth and controlling of seedling blight.
