目前我们对小麦赤霉病的预报主要是依据小麦生育期与气象条件的吻合程度。在正常年份,小麦生育期相对较易根据叶龄余数进行超前预测,而小麦感病期的天气状况的超前预报目前尚不过关,所以目前小麦赤霉病的预报尚有一定困难,预报的准确性还不够理想。近年来,我们运用小麦生育期中已经出现的天气实况,进行小麦赤霉病的分段预报,取得了初步成效。
At present, our forecast of wheat head blight is mainly based on the coincidence of wheat growth period and meteorological conditions. In normal years, the growth period of wheat is relatively easy to predict ahead of time based on the leaf age margin. However, the forecast of the weather conditions in the period of wheat susceptibility is not yet at present. Therefore, the forecast of wheat scab has some difficulties at present, and the forecast is accurate Sex is not good enough In recent years, we have used the live weather in the growing period of wheat to carry out the sub-forecast of wheat scab and achieved initial results.
