宝鸡地区是我省老产烟区,历来种植麦茬烟。1968年以后,烟草花叶病危害严重,造成烤烟低产劣质,影响种植面积和国家烟叶收购计划。因此,防治烟草花叶病已成为急需解决的问题。烟草花叶病还没有可行的防治措施。在生产实践中常看到,同一年份,同一品种在不同地块花叶病的发生危害程度不同。为了寻求防治的有效栽培措施,我们经过广泛调查和观察试验,围绕麦烟套种防治烟草花叶病的效果进行了研究。一、研究方法和结果 Baoji region is the oldest tobacco-growing areas in our province, has always planted wheat stubble smoke. After 1968, tobacco mosaic disease is seriously endangered, resulting in low yield and poor quality of flue-cured tobacco, affecting planted area and the acquisition plan of national tobacco leaves. Therefore, the control of tobacco mosaic disease has become an urgent problem to be solved. Tobacco mosaic disease there is no feasible control measures. In production practice often see that the same year, the same species in different plots Mosaic hazards are different degrees of harm. In order to seek effective cultivation measures for prevention and control, we conducted extensive investigations and observations on the effects of tobacco seed mosaic disease control on tobacco mosaic disease. First, research methods and results
