初步分析了恩施烟区青枯病不同发病程度的土壤理化性状与青枯病发病率的关系.结果表明,土壤某些理化指标与青枯病发病程度有密切关系,随着植烟土壤温、湿度和紧实度的增大,发病率增高;随着植烟土壤中速效钾、pH、重碳酸根、硫酸根离子和阳离子交换量的增大,发病率降低.

The relationship between occurrence rate of tobacco bacterial wilt at various severities and soil physical and chemical properties was analyzed to investigate the possible cause of the disease occurrence. The results showed that there were close relationship between soil physical and chemical properties and bacterial wilt. The incidence index increased with increasing soil temperature, humidity and compaction, but decreased with increasing soil available potassium, pH, bicarbonate, sulfate and CEC.
