三唑酮拌种可以显著地防治多种病害,而起到保产效果,但在不防病或者病害极轻不致于造成产量损失的情况下,拌种对小麦产量有何影响是个必须明确的问题。通过三年的不同地区试验,取得了结果。一、材料与方法供试药剂有南开大学元素所、四川省化工研究所和西德拜耳公司产的三唑酮可湿性粉剂。采用干拌方法,其拌药量(有效成分)为种子重量的0.03%(例外的则有指明)。选择地势平坦,肥力均匀的地块,
Triadimefon seed dressing can significantly prevent and control a variety of diseases, and play a yield-saving effect, but without disease prevention or disease caused by minimal yield loss, the impact of seed dressing on wheat yield is a must be clear problem. After three years of experiments in different regions, the results were obtained. First, the material and methods for testing agents Nankai University Institute of Element, Sichuan Institute of Chemical Technology and West Bayer company triadimefon WP. Using dry mixing method, the amount of its mixture (active ingredient) is 0.03% of the weight of the seeds (exceptions are specified). Select flat, fertile land plots,
