潜育菌量,是潜育在植株内部尚未表现出来的病菌数量。在冬麦区,秋苗感染较晚的植株,由于温度降低,不适宜锈菌的发展,锈菌往往以菌丝状态较长时间地潜伏在植株内部,成为翌春当地早期流行的主要菌源。所测定地区锈病的种类及数量,可作为预测预报的重要参考。在冬季气温较低而麦叶仍然保持绿 The amount of latent bacteria, is the number of bacteria that have not yet been shown in the plants. In the winter wheat area, late autumn seedlings infected plants, due to lower temperature, unsuitable for the development of rust, rust often mycelium state lurking in the plant for a long time, become the next spring local early epidemic of the main source of bacteria . The type and amount of the detected rust in the area can be used as an important reference for forecasting and forecasting. In winter the temperature is low and the wheat leaves remain green
