实施以血清跟踪检测病毒为中心，结合杜绝病毒再侵染系列配套技术措施，确保无病毒葡萄母株园发病率在10％以下，经四年跟踪检测GLRV-Ⅲ和GFV均属阴性反应。结果率和结果系数高、果穗和果粒重增加、果穗紧、果粒均匀和成熟一致等，丰产潜力大。 Implementation of serum tracking and detection of viruses as the center, combined with the elimination of virus reinfection series of supporting measures to ensure that the virus-free grape plantation in the incidence of less than 10%, after four years of follow-up test GLRV-Ⅲ and GFV are negative reactions. The result rate and result coefficient are high, the ear and fruit weight are increased, the ear is tight, the fruit is uniform and mature, and the yield potential is high.
