根据小麦丛矮病传毒媒介昆虫灰飞虱在麦田枯叶下、土缝中和麦根旁栖息越冬的特点,以及小麦返青后灰飞虱复苏活动迁移麦苗上的规律,我们在1976年进行了轧麦除虫防病试验,收到了较好的效果。1977年省有关部门提倡全省试验示范253万亩。为了进一步明确轧麦的治虫防病效果,1977年和1978年我们又进行了试验示范,同样收到了稳定的良好效果。据试验,轧麦的适宜时期在3月上旬左右或日平均气温5—8℃ According to the wheat dwarf virus vector poisoning Laodelphax striatellus in the wheat field under the dead, the soil cracks and winter perch habitat overwintering characteristics, and wheat rejuvenation after the Laodelphax striatellus translocation activity of wheat seedlings on the law, we carried out in 1976 The wheat disease and insect pest control test, received a good result. In 1977, relevant departments of the province advocated experimenting with 2.53 million mu in the province. In order to further clarify the pest control effect of rolling wheat, in 1977 and 1978 we conducted a pilot demonstration, also received a stable and good results. According to the test, the appropriate period of rolling wheat in early March around the average daily temperature of 5-8 ℃
