"抑花一号"药剂对木棉飞絮的治理研究
Study on Treatment of Kapok Flying-catkins with"Yihua No.1"
摘要
Abstract
In order to solve the inconvenience caused by the flying-catkins of kapok,different concentrations of"Yihua No.1"were carried out at the final flowering stage of kapok to study its influence on the formation and development of kapok fruit.Results showed that the application of"Yihua No.1"at the last flowering stage of kapok had a very significant effect on promoting abortion and fruit drop of kapok,and the higher the concentration of the drug,the more obvious the effect.A 3-year follow-up investigation showed that after the application of"Yihua No.1",the sample plants appeared different degrees of trunk cracking,secreting gum,abnormal sprouting,dead branches,and weakened tree potential and so on.By the next year,the flower formation was inhibited,and some of them could not even complete flower bud differentiation.The higher the concentration,the more obvious such damage.Considering the effect of"Yihua No.1"and its adverse effects on trees,0.5%concentration with 25 mg/cm,or 1%concentration with 12.5 mg/cm were recommended to use in production.关键词
