采用麦蚜指数调查法进行田间穗蚜计数，所用时间较实际逐个计数明显缩短。本试验平均百穗缩短调查时间１２９２ｍｉｎ，利用方程Ｙ＝－６２５＋４６２Ｘ，推算出的蚜量，误差不超过１头／穗 Wheat aphid index survey method for the field spikes aphid count, the use of time than the actual count by one significantly reduced. In this experiment, the average ear length reduced the survey time 1292min. Using the equation Y = -625 + 462X, the calculated aphid amount did not exceed 1 head per ear
