| 摘 要： | 通过人工接种筛选抗病品种资源,研究播期、种植密度对病害发生的影响,明确玉米镰孢菌穗腐病发生与品种资源、播期、种植密度的关系,分析棘孢木霉菌颗粒剂(TCF)和XDS种衣剂(40%毒死蜱乳油、20%辛硫磷和10%井岗霉素混剂)对玉米穗腐病的防效。结果表明,32个自交系中有6个抗病自交系,延迟播种玉米镰孢菌穗腐病发生严重,播种密度对病害发生程度无显著影响。人工接种条件下,TCF颗粒剂穴施、XDS种衣剂拌种2个处理表现为百粒重增加、秃尖长度降低,TCF颗粒剂穴施处理的防效最高,为48.69%。

| Abstract: | To identify varieties resource and explicit effect of sowing date, plant density to occurrence of maize ear rot, control efficiencies of TCF granules and XDS seed coating agent against maize ear rot, the pot and field experiments by artificial inoculation with Fusarium verticillioides and F. graminearum were conducted. The results showed that 6 of 32 inbred lines were resistant to maize ear rot, occurrence degree of maize ear rot was serious at late sowing date, no obvious variation at plant density. hundred grain weight increasing and bald grain long decreasing at TCF granule and XDS seed coating agen. 48.69% control efficiency was able to achieve by TCF granule, |
