摘　　要：为筛选防效优良的微生物应用于作物病害防治中,同时开发一条安全的补硒途径进行富硒农产品的生产,对前期筛选到的防御假单胞菌KBD-3进行了抗病及纳米硒化研究。结果表明,KBD-3菌液对烟草花叶病毒具有较好的钝化效果,抑制率高达95.77%,同时对青枯雷尔氏菌的抑制效果较好,对烟草青枯病的相对防效达70.89%。另外,KBD-3可将亚硒酸钠还原为纳米硒,经纳米硒溶液处理的绿豆芽中硒含量大幅提高。这表明,KBD-3不仅为作物病害防治提供新的微生物资源,还能较好地用于作物的富硒培育。In order to screen the microorganisms with good control effect for crop disease control and develop a safe way of selenium supplementation for the production of selenium-rich agricultural products,the disease resistance and nano-selenization of Pseudomonas protegens KBD-3 were studied.The results showed that the KBD-3 bacterial solution had good inactivation effect on tobacco mosaic virus(TMV),the inhibition rate was 95.77%,and had a good inhibition effect on Ralstonia solanacearum with the relative control effect on tobacco bacterial wilt reaching 70.89%.In addition,KBD-3 could reduce sodium selenite to nano-selenium,and the selenium content of mung bean sprouts treated with nano-selenium solution was greatly increased.These indicated that KBD-3 did not only provide a new microbial resource for crop disease control,but also could be used for selenium-rich cultivation of crops.
