摘要
通过2011年的小区试验表明,在移栽期和中耕期施用植物有机诱导抗病剂"多肽保",可以促进大田烟株生长整齐、发育良好,对烟草赤星病的防效达到71.23%～78.83%,单位面积内产量增加7.97%～15.97%,产值增加11.00%～20.77%,为防治烟草赤星病提供了一条新途径.
The district tests in the year 2011 showed that the application of plant organic induced resistant agent of ＂polypeptide-product＂ during transplanting and cultivating period can not only promote the growth and development of tobacco plants, but also achieve the control effects to 71.23%--78.83% on tobacco Alternaria alternata. The production per unit area increased 7.97%--15.97%, and the output value increased 11.00% --20. 77%. The usage of ＂polypeptide-product＂ provides a new way of prevent and control the tobacco brown spot disease by application of biotechnology on tobacco industry.
