小麦白秆病是高寒地区小麦上特有的病害,病原属半知菌类(SeLenoPhomΛ·SP)。试验证明:带病种子是主要的初次侵染源,大田发病后,分生孢子随风雨传播,引起再次危害。 1969年以来,我所对白秆病的发生规律及其防治作了一些零星的研究。试验证明:采取种于处理对控制病害传播蔓延有一定效果,但对该病的发生规律,尚不明瞭。为了明确小麦白秆病的发生规律,为病害防治提供理论依据,在前几年研究的基础上,1975
Wheat stalk disease is a peculiar disease on wheat in the alpine region, and the pathogen is SeLenoPhomΛ · SP. Tests show that: diseased seeds is the primary source of primary infection, the onset of the field, the conidia spread with the wind and rain, causing another harm. Since 1969, I made some sporadic studies on the law of occurrence and control of white stalk disease. Experiments show that: to take measures to control the spread of disease has a certain effect, but the incidence of the disease is not clear. In order to clarify the occurrence of wheat white stalk disease, provide a theoretical basis for disease prevention and control, based on a few years ago, 1975
