研究提出了一种新的高粱蚜测报办法。把一年内麦蚜和高粱蚜发生程度的和定为6级,得出麦蚜发生级别后,被6减去,所得差数就是当年高粱蚜的发生级别。经三年验证,这种方法的测报准确性较高,而且可比常规测报法提前发出测报一个月左右。 The study proposed a new measurement method of sorghum aphid. The level of occurrence of wheat aphid and sorghum aphid within one year was defined as level 6, and after the level of occurrence of wheat aphid was deducted by 6, the difference was the occurrence level of sorghum aphid in that year. After three years of verification, this method of reporting accuracy is higher, and can be sent ahead of schedule than the conventional method of measuring a month or so.
