一、关于病名小麦丛蘖病,过去多叫霜霉病,也称黄化萎缩病.人们惯于将霜霉菌引起的植物病害统称霜霉病.其理由一方面是为了统一,更主要的是这类病害多能在叶背病斑组织上产生一薄层霜状霉.尽管有的霉层并非全呈霜状,但总是生有一层深灰或灰紫色的霉.而在小麦上并非如此,到目前为止,除日本外,尚未发现病株上产生霜状霉层的现象,因此在小麦上也叫作“霜霉病” 就很不恰当.若以黄化萎缩病命名,虽是接近了症状的实际,但是不很全面.因为该病主要发生在苗期,同时症状又主要表现为分蘖增多、丛生发黄,故更名为小麦丛蘖病.
First, on the disease name Wheat tiller disease, in the past called downy mildew, also known as yellowing atrophy .People are accustomed to the plant diseases caused by downy mildew collectively known as downy mildew.The reason is on the one hand for the unity, more importantly Such diseases can often produce a thin layer of creamy mildew on the diseased plaque of leaves.Although some mildew layers are not completely creamy, they are always born with a layer of dark gray or gray-purple mildew, but not on wheat So far, except in Japan, no frost-like mold layer has been found on diseased plants, so it is inappropriate to call it “downy mildew” in wheat. Close to the actual symptoms, but not comprehensive, because the disease occurs mainly in seedling stage, while the symptoms are mainly manifested as increased tillers, clusters of yellow, it changed its name to wheat tiller disease.
