| 摘 要： | 昌黎鳳凰山一带葡萄栽培历史已有250年左右。近年来由于黑痘病害的流行,产量降低一半。过去虽曾以波尔多液进行防治,但因未能掌握当地該病发生的規律,故末获得預期的效果。本文为作者在1955年及1956年在昌黎县十里鋪乡对該病研究的初步报告。

| Abstract: | Anthracnose of Grape (Elsinöe ampelina (De Bary) Shear) in Changli district has caused heavy losses in recent years.
Field observations in 1955 and 1956 demonstrated that hibernating mycelium in fallen leaves,dead vines on the ground and lesions on shoots begin to sporulate in the middle of May when the conditions are favorable.In the past two years,new infections usually started in early June when the vine began to bloom.A climax of infection is reached in late June to July.The spread of the disease became slower from mid August on and stopped entirely in mid October. |
