黄瓜是我区菜篮子里的主要蔬菜,具有分布广、种植面积大、产值高等特点。但是由于黄瓜霜霉病、黄瓜细菌性角斑病和黄瓜炭疽病的危害,严重地影响了黄瓜的产量和质量,是黄瓜生产的重大障碍。所以,必须要抓好以上三种病害的防治。 Cucumbers are the main vegetables in the vegetable basket in our district. They have the characteristics of wide distribution, large planting area and high output value. However, due to cucumber downy mildew, bacterial angular leaf disease cucumber and cucumber anthracnose damage, seriously affecting the cucumber yield and quality, cucumber production is a major obstacle. Therefore, we must do a good job in the prevention and treatment of the above three diseases.
