李埠区是我县小麦的主产区,常年种植面积25,000亩,由于小麦条锈病的危害,一般年份减产10—20％,严重年份减产40—50％,是小麦生产中需要解决的一个难题。为摸索化学防锈的途径,1983—1984年中国农科院植保所等单位,在李埠区进行了粉锈宁拌种防治条锈病的大面积试验示范,取得了显著效果。现将试验示范结果简结如下。 一、材料与方法
Li Bu District is the main producing area of wheat in our county. The annual perennial acreage is 25,000 mu. Due to the harm of wheat stripe rust, the annual yield is reduced by 10-20% in most years and 40-50% in severe years, which is a problem to be solved in wheat production . To explore the way of chemical rust prevention, 1983-1984 Chinese Academy of Agricultural Sciences Institute of Plant Protection and other units in the Li Buqu conducted a large-scale test and trial of triadimefon seed dressing to control stripe rust, and achieved remarkable results. The demonstration results are summarized below. First, materials and methods
