花生花叶病是由病毒引起的一种常见侵染性病害,该病在国外已有很多研究报导。近几年,花生花叶病在我国花生主要产区的辽宁、山东、江苏、河北等地均有大面积发生,其中尤以辽宁省的旅大地区发病较为严重。据调查,发病率低者20％左右,高者80—90％,重者可达100％,发病面积逐年在扩大。一般可导致花生减产20％左右。因此,花生花叶病已成为当前生产急需解决的课题。目前对此病害存有两种不同看法:一种认为是病毒病害;另一种认为是生理病毒。为了弄清花生花叶病的发病原因,我们从1975年以来,对该病进行了一些试验研究工作,本文主要报导我们1975—1977年对本病害的试验研究结果。 Peanut mosaic disease is a common infectious disease caused by the virus, which has been reported in many foreign countries. In recent years, peanut mosaic disease has occurred on a large scale in Liaoning, Shandong, Jiangsu and Hebei, the major peanut producing areas in China. Especially in Liaoning Province, the incidence of Lvda area is more serious. According to the survey, the incidence rate is low about 20%, the highest 80-90%, severe cases up to 100%, the incidence of the area is expanding year by year. Can generally lead to about 20% reduction in peanut production. Therefore, peanut mosaic disease has become an urgent issue to be solved in current production. Currently there are two different views on this disease: one is considered a virus disease; the other is considered a physiological virus. In order to understand the cause of peanut mosaic disease, we have carried out some experimental studies on the disease since 1975. This paper mainly reports the results of our experimental study on this disease from 1975 to 1977.
