枸杞子(Lycium barbarum L.)是我国名贵中药材之一,原产于宁夏、甘肃一带,河北、山东、河南等地引种试种成功,并大量生产。但由于枸杞黑果病的发生,近年来在新产区造成常年减产达50％左右,最高达80％以上。因此防治该病的发生蔓延成为枸杞子生产中的重要课题。 Lycium barbarum L. is one of the precious Chinese medicinal materials in our country. It was native to Ningxia and Gansu Provinces. It was successfully introduced and mass-produced in Hebei, Shandong and Henan. However, due to the occurrence of Lycium berry disease, perennial production in the newly-produced areas has been reduced by about 50% in recent years, up to 80% or more. Therefore, prevention and treatment of the spread of the disease has become an important issue in the production of medlar.
