1、茉莉酸甲酯协同摩西球囊霉对草莓连作障碍的防控效果齐永志sx®河北阜平县职业技术教育中心河北农业大学植物保护学院摘要:[目的]研宄茉莉酸甲酯与摩西球囊霉对草莓连作障碍的防控效果。[方法]通过小IX:试验测定茉莉酸甲酯蘸根协同接种摩丙球囊霉对红颜和章姬菌根侵染率、牛.长、产量及根病发生的影响。[结果]茉莉酸甲酯蘸根显著提高了摩西球囊霉在根系侵染率。与对照相比,协同处理提高了草莓生物量,红颜和章姬产量分别高达30235.1、31065.1kg/hra2,增产率分别为31.9%和19.3%,果实品质未发生明显变化;收获期协同处理对2种草莓根病防效分别为72.8%和60.8%,
2、但均低于氯化苦处理。[结论]荣莉酸甲酯蘸根协同接种摩丙球囊霉对草莓连作障碍有较好的防控效果。关键词:草莓;摩西球囊霉;茉莉酸中酯;连作障碍;作者简介:曲俊梅(1972一),女,河北阜平人,高级讲师,学士,主耍从事作物栽培学研究。E-mail:qujunmei1972@163.como作者简介:齐永志(1981一),男,河北保定人,硕士生导师,博士,主要从事植病生态学研究。E-mail:qiyongzhi1981@163.com。收稿日期:2017-07-20基金:W家自然科学基金项目(31140064)ControlEffectofMethylJasmonateand
