水稻矮缩病和黄矮病(两矮病)预测模式(y=h·d·p·t/x)经1981～19182年多点示范应用结果,能较为准确地测报晚稻矮缩病的株发病率,并能运用预测因子p值指导矮缩病和黄矮病并发流行区的田间防治。
Rice dwarf disease and yellow dwarf disease (dwarf disease) prediction model (y = h · d · p · t / x) by 1981 ~ 19182 more demonstration application results, can be more accurately reported late dwarf strain Incidence, and can use the predictor of p value to guide the dwarf disease and yellow dwarf disease epidemic area of field control.
