我县位于鲁西北平原,长期以来,夏播玉米苗期的病虫危害一直较重。为了探索种衣剂在玉米生产上的应用效果,1996年我们设计了种衣剂包衣和呋喃丹播种的比较试验,为在生产上大面积推广利用种衣剂提供了科学依据。 1 材料与方法 1.1 试验材料:供试品种为我公司自产玉米杂交种掖单12号。种衣剂和呋喃丹均为天津市北方种衣剂中试厂提供。试验地前茬作物小麦。土壤肥力中上等,排灌便利。 1.2 试验方法:本试验设3个处理:①天津市种衣剂厂生产 My county is located in the northwestern plain of Shandong Province. For a long time, the pest and disease hazards of summer sowing maize have been heavier. In order to explore the application effect of seed coating agent in corn production, in 1996 we designed a comparative test of seed coating agent and carbofuran sowing, which provided a scientific basis for the popularization and utilization of seed coating agent in production. 1 Materials and Methods 1.1 Test Materials: The test varieties for our company produce hybrid corn Yedan 12. Seed coating agent and carbofuran are tested in northern seed coating plant in Tianjin. Test crop before crop wheat. Top soil fertility, irrigation and drainage facilities. 1.2 Test Methods: The test set 3: ① seed coating plant in Tianjin
