麦类粘虫预测报,大致经历了50—60年代成虫观测法,70年代起的草把诱卵和成虫观测法相结合的综合预测法以及80年代起使用单一的草把诱卵测报,这三个阶段。从繁到简、从多样到单一,是该项测报技术不断提高和完善的结果。但小草把诱卵测报办法试行十多年来仍有不足之处,尤其是感到草把诱卵的时间经历太长,按现行统一的观测时间,即从二月十日至四月二十日要经历60—70天,把测报人员有限的精力长期束缚在草把诱卵一项工作
The wheat-based armyworm predictor reported roughly experienced adult observations in the 1950s and 1960s, the integrated forecasting method of combining grass and adult observations with grass in the 1970s, and the use of a single grass in the 1980s to report ovulation A stage. From traditional to simple, from variety to single, is the result of continuous improvement and improvement of the technology. However, the grass has still had some deficiencies in the trial implementation of the method of detecting and reporting eggs by more than a decade. In particular, it has felt that the time it takes grass to induce eggs is too long. According to the current uniform observation time from February 10 to April 20 Day to go through 60-70 days, the limited ability of the newspaper reporter limited long-term constraints in the grass to induce a job
