Many vegetable farmers in Shijiazhuang, Shouguang City, Shouguang City, mainly use cucumber as a bitter gourd. At present, most of the cucumbers are in the late stage of growth. The next management focus will be transferred to bitter gourd. The reporter found that after visiting several greenhouses, As the late cucumber management is relaxed, the occurrence of diseases is more. Therefore, the management of the greenhouses in the same room where the two crops are located should be strengthened to prevent the spread of diseases. It is mainly prepared from the following two aspects.
First, cucumber management.
The growth of plants at the end of the cucumber's growth is weakened, and the disease resistance is reduced. Therefore, it will be more prone to diseases than usual. At the same time, after the benefit of the cucumber at the end of growth, the vegetable growers will relax the management, and the resistance of the plants themselves will be reduced. After the management, many diseases will occur, such as cucumber anthracnose, powdery mildew, etc. If they are not prevented, it will be difficult to treat them after they occur. The bacteria in the shed will infect the bitter gourd. Therefore, the late management of cucumber Can not relax, we must promptly prevent the occurrence of disease.
However, the current weather is uncertain, diseases will inevitably occur in the shed, and the prevention and treatment of such diseases should be carried out as soon as possible to prevent transmission to bitter gourd. After the cucumber is pulled out of the garden, the diseased plants are promptly brought out of the shed and subjected to greenhouse disinfection. For example, the chlorothalonil and the smoke agent can be used for the treatment of the shed and the pathogen spores in the shed can be killed.
Second, bitter gourd management.
Now the bitter gourd has just been brought up. It is in the growth stage. The growth is weak. If the growth environment is not suitable or there are more pathogenic bacteria in the shed, it will be easy to infect the disease. Therefore, the current bitter gourd should be timely prevented from occurring in the management process. Requires timely spraying of chlorothalonil, carbendazim and other protective bactericides, among which spot disease is a disease that is more prone to bitter gourd. Such diseases use thiazole zinc, Xiangnong 5, and other control effects.
