棉花根病的接种方法,一般采用拌种、浸种和土壤接种法。这些方法虽然使用方便,但病程较长,发病程度不一致。为适应多种药剂的筛选,缩短发病周期,试用棉芽接种法。经多次试验,棉芽接种法发病率高,接种及感病条件都容易控制,发病周期短(在适温、高湿的条件下,2～3天即可发病),棉苗的发病程度亦较为一致。具体方法:用温汤浸种处理棉籽,沥干后
Cotton root disease inoculation methods, the general use of seed dressing, soaking and soil inoculation method. Although these methods are easy to use, but a longer duration, the incidence is inconsistent. In order to adapt to a variety of pharmaceutical screening, shorten the incidence of cycle, try cotton bud inoculation method. After many tests, cotton bud inoculation method has a high incidence of inoculation and susceptible conditions are easy to control, the incidence of period is short (under the conditions of temperature, high humidity, 2 to 3 days to disease), the incidence of cotton seedlings Also more consistent. Specific methods: seed soaking cotton seed soaking, drained
