小麦白秆病是青藏高原的一种新病害。小麦感染了这种病,轻的减产2—3成,重的可减产6—7成。被列为我省控制传播的危险性病害之一。由于小麦白秆病主要是通过带病种子传播的,因此,严格检疫制度,是控制蔓延的有效措施。自1976年以来,我们初步摸索出检查种子是否带病以及病菌存在的部位的办法。一、种子解剖镜检:这是基本的俭验方法。根据田间现场观察,染白秆病的植株所 White stalk disease is a new disease in the Tibetan Plateau. Wheat is infected with this disease, light cut 2-3 percent, heavy cut 6-7 percent. Is listed as one of the dangerous diseases in our province to control spread. As wheat stalk disease is spread mainly through diseased seeds, the strict quarantine system is an effective measure to control the spread. Since 1976, we have tentatively explored ways to check whether the seed is diseased and where the germs are present. First, seed dissecting microscopy: This is the basic method of frugality. According to field observations, stained with white stalk plants
