预测预报是防治病虫的耳目,只有全面了解虫情,预先掌握害虫的动向,才能做到防治主动、及时,才能打得准、打得狠。但实践证明,要使测报工作及时准确,必须依靠广大群众。因而测报方法必须简便,易被群众掌握。为此,我们近年来根据油松毛虫在黄龙林区的发生规律,采用图式法,开展了油松毛虫的测报工作。初步证明这种方法简单适用,在生产上起到了一定的作用。现将具体方法介绍于后。
Prediction is the prevention and control of pests and diseases of the eyes and ears, only a comprehensive understanding of insects, pre-grasp the movements of pests in order to achieve prevention and control initiative, timely, to play accurate, playing ruthless. However, practice has proved that in order to make timely and accurate reporting, we must rely on the masses. Therefore, the reporting method must be simple and easy to grasp by the masses. To this end, in recent years, according to the occurrence of pine caterpillars in the Huanglong forest area, we adopt the schema method to carry out the measurement of the oil caterpillar. Preliminary proof of this method is simple and applicable, has played a certain role in the production. The specific method is introduced later.
