摘要
以有髯鸢尾品种‘不朽白’为试材,研究不同浓度20%噻森铜悬浊液对有髯鸢尾软腐病发病率及病株再萌发率的影响。结果表明:各处理均降低了‘不朽白’软腐病发病率,并在一定程度上提高了病株的再萌发率;以浓度为750 mg/L的效果最好,比对照发病率降低了43.3%,再萌发率达到了58.33%。
Bearded Iris＇Immortality＇ was used as test material,the effects of different concentrations of 20% Saisentong turbid liquid on incidence rate of bacterial soft rot and germination rate of diseased plants of Bearded Iris ＇Immortality＇.The results showed that 20% Saisentong turbid liquid had obvious control effect against bacterial soft rot,the incidence of Bearded Iris with 750 mg/L was 40%,decreasing 43.3% compared with CK and the germination rate of diseased plants reached to 58.33%.
