白叶枯病是水稻的一种主要病害,发病严重时,极大地影响产量。目前国内外还没有一种理想的防治药剂,因此是农抗筛选工作中的重要研究课题。白叶枯病新农抗的筛选,常用的有二类方法:一类是沿用医抗筛选的平板抑菌圈测定法,或稍加某些改变。这种方法虽然简便,但其可靠性,即和田间实际防治效果之间的相关性,以及在农抗初筛工作中的意义,仍存在不同的看法。另一类是植株测定法,即用盆栽稻或试管稻苗接种测定法。盆栽试验和田间测定虽有一定的相关性,但是,需要较长的时间(十多天)和设备较好的温室,对于迅 Bacterial blight is a major disease of rice, when the disease is serious, it will greatly affect the yield. At present, there is not an ideal control agent at home and abroad, so it is an important research topic in agricultural anti-screening work. There are two types of methods commonly used for screening new pests of bacterial leaf blight: one is to follow the antimicrobial assay method of medical anti-screening, or add some slight changes. Although this method is simple, its reliability, that is, the correlation with the actual control effect in the field and the significance in the screening of agricultural anti-screening are still different. The other is the plant assay, which uses potted rice or test tube inoculation assay. Pot experiments and field measurements, although a certain degree of relevance, however, takes a longer time (more than ten days) and equipment better greenhouse, fast
