葡萄黑痘病(Sphaceloma ampelinum de Bary),对葡萄某些种群中的品种是一种带毁灭性的病害。过去该病在湖南境内的发生场所,发生发展规律,不同品种感染和抗性程度,不同栽培技术措施以及不同防治方法的效果,都缺乏深入的研究。因此省内一些葡萄引种单位,一旦黑痘病发生,就不知所措,有的虽沿用北方的一些防治方法,但未能取得明显的效果。这在一定程度上给发展葡萄生产带来了障碍。本试验就是针对上述情况而设置的。现将研究的初步结果归纳如下。
Sphaceloma ampelinum de Bary is a devastating disease on some of the grapevine species. In the past, the disease occurred in Hunan, place of occurrence, the occurrence of the law of development, different varieties of infection and resistance levels, different cultivation techniques and methods of prevention and treatment of different effects, lack of in-depth research. Therefore, the introduction of some grapes units in the province, once the acne disease occurs, overwhelmed, while some use some of the prevention and control methods in the north, but failed to achieve significant results. To a certain extent, this has brought obstacles to the development of grape production. This test is set for the above situation. The preliminary results of the study are summarized as follows.
