春耕播种工作已基本结束,除虫保苗即成为当前农业生产上的主要任务之一。据运城、闻喜、稷山等县检查,4月中旬棉苗刚出土,棉蚜即侵入为害,截至5月上旬寄生株率已达10—15%,每株平均有蚜虫十个,最多的一株达五十个。棉苗病害亦很严重,据运城附近检查,一般发病率均在80%左右,死苗率为12.6%,严重的死苗率竟达70%。临汾地区棉田,地老虎为害严重,棉曲平均被害为20.4%,有的达43%,造成严重的缺苗断垄。汾阳贾家庄等地亦发现破地老虎为害玉米幼苗。晋北、晋东南部分地区发现东方金龟子为害秋禾幼苗等情况。根据我省植物检疫保护站研究分析,去冬今春气温较高,各种病虫越冬死亡较少,发生为害时期要比往年提早,各种病虫害都有大发生的可能,这对秋作物幼苗的生长,将是很大的威胁。为了保证今年农业生产的更大丰收,各地对这一情况必须有
Spring planting has basically ended the sowing, pest control seedlings that have become one of the main tasks of agricultural production. According to Yuncheng, Wenxi, Jishan and other counties in mid-April cotton seedlings just unearthed cotton aphids that invaded the damage, as of early May parasitic plant rate has reached 10-15% per plant average of 10 aphids, the most A strain of fifty. Cotton seedlings disease is also very serious, according to the inspection near Yuncheng, the general incidence of about 80%, dead seedlings rate was 12.6%, severe death rate as high as 70%. Linfen area of cotton fields, to severely damage the tiger, cotton average damage was 20.4%, and some 43%, resulting in serious lack of seedlings off ridge. Fenyang Jiajiazhuang and other places also found broken tiger damage corn seedlings. Jinbei, southeastern part of the eastern part of the discovery of oriental chafer damage autumn seedlings and so on. According to the research and analysis of the plant quarantine and protection station in our province, the temperatures are higher in winter and spring than in winter, all kinds of pests and diseases have fewer deaths in wintering, the damage period is earlier than previous years, and all kinds of pests and diseases are likely to occur. Growth, will be a big threat. In order to ensure a greater harvest of agricultural production this year, all over the world must have this situation
