病虫测报是对未来事件做出估计。我们很难预测事件发生在时间、空间某一确定性的点,但我们有可能预测事件发生的范围,预报事件发生的各种可能性。我们把失误的原因归为以下几点:1.气象部门的预报不准确,使得我们的测报出现偏差。2.病虫发生的实地监测不准确,对情况了解不明。3.测报方法不妥。一般情况下,气象预报的预报时间同准确性呈反比,特别是对于中、长期预报,一般只能做出范围或幅度估计。这一可能性到
Pest forecasting is to make an estimate of future events. It is difficult to predict the event happens at a certain point in time and space, but it is possible to predict the scope of the event and predict the possibilities of the event. We put the reasons for the mistakes are as follows: 1. Meteorological forecast is not accurate, making our measurement deviation. 2. Field monitoring of pests and diseases is not accurate, the situation is unknown. 3. Report inappropriate method. In general, the forecast time of the weather forecast is inversely proportional to the accuracy, especially for mid- and long-term forecasts. Generally, only the range or the range estimate can be made. This possibility to
