一、选用良种芝麻生产应选用高产优质、抗逆性强、籽粒纯白的豫芝8号、豫芝10号等品种。为了克服芝麻连作出现的产量低、病虫害严重等现象,经反复试验示范,同一块地上,上年种植豫芝8号,下年种植豫芝10号比仍种豫芝8号增产10.8%,发病率降低13.6%,因此应大力提倡上下年间良种调换。二、轮作换茬芝麻连作,会使病害加重,据试验示范,连作一年,大田发病率达 First, the selection of elite sesame production should use high yield and quality, strong resistance, pure white grain Yuzhi 8, Yuzhi No. 10 and other varieties. In order to overcome the sesame crop production appears low, severe pests and other phenomena, after repeated tests and demonstrations, the same piece of ground, the previous year planting Yuzhi No. 8, the next planting Yuzhi No. 10 than Yuzhi 8 yield 10.8% increase in incidence The rate of reduction of 13.6%, it should vigorously promote the next year, good seed exchange. Second, the rotation cropping sesame continuous cropping, will make the disease worse, according to test demonstration, even for a year, the incidence of field up to
