在对豆秆黑潜蝇发生规律研究的基础上进行了一组防治试验,从这组试验结果不仅看出不同药剂不同防治方法和时间对大豆的增产作用,而且能通过不同抑制效果,看出大豆茎秆中的虫量与增产率的相关关系,并可求出茎秆中的虫量与大豆增产率的相关回归方程,来分析豆秆黑潜蝇不同发生程度下的损失率。现将试验结果整理如下。
A series of control experiments were conducted on the basis of the study on the law of Occurrence of Stem Black Sootfish. The test results of this group not only showed the increasing effect of different control methods and time on Soybean, but also showed different inhibitory effects Soybean stalks in the amount of insects and the relationship between the rate of increase, and can be calculated stems in the amount of insects and soybean yield-related regression equation to analyze the occurrence of different levels of Stem Black Mlyfogon loss rate. The test results are summarized below.
