去年,我社15,000亩杂交高粱普遍发生棉铃虫。我们应用西维因农药进行了田间防治试验,取得了良好的防治效果。防治试验是在塔山一队,东大甸虫害比较严重,生长一致的“晋杂一号”高粱地上进行的。高粱平均株高198厘米,全部出了穗,青米穗占48%,扬花穗占30%,半扬花穗占22%。 Last year, 15,000 mu hybrid cotton sorghum was commonly reported in our society. We applied the West for pesticide field control trials, and achieved good control effect. Prevention and control test was carried out on the first team of Tashan and the more serious insect pest in Dongdaelang and the consistent growth of “Jinza-1” sorghum. Average sorghum plant height of 198 cm, all out of the ear, ear of young rice accounted for 48%, 30% of the flowering spike, accounting for 22% of the half-flowering spikes.
