蔬菜菌核病过去在北京菜田发生较少,主要为害大白菜种株,对产量影响不大。但自保护地大发展以来,为蔬菜菌核病的发生创造了良好的条件,目前茵核病已成为保护地蔬菜的一个重要病害。据我们在北京调查,发生菌核病的蔬菜有黄瓜、番茄、芹菜、芸豆、莴笋、甜椒等。以黄瓜和番茄受害最重。严重田损失可达70%。目前虽发生尚不普遍,但病情仍在发展之中。这种情况呼和浩特已有报导(黄瓜菌核病)。一些保护地发展较早的国家蔬菜菌核病也比我国北方严重。因此我们应当加强蔬菜菌核病的防治,以免造成更大的损失。
Vegetable sclerotinia occurred in the past less vegetable fields in Beijing, the main damage to Chinese cabbage strains, little effect on the yield. However, since the great development of protected areas, it has created good conditions for the occurrence of sclerotinia in vegetables. At present, it has become an important disease of vegetables in protected areas. According to our investigation in Beijing, the occurrence of sclerotinia vegetables cucumber, tomato, celery, kidney beans, lettuce, sweet pepper and so on. To cucumber and tomato victims most. Severe field loss up to 70%. Although the occurrence is not common now, the condition is still under development. Hohhot has been reported in this case (cucumber sclerotinia). Some of the protected areas of the development of earlier national sclerotinia than China’s northern serious. Therefore, we should strengthen the prevention and treatment of sclerotinia in vegetables so as to avoid greater losses.
