Most of the gray mold bacteria invade from the flower after opening, causing the flower to rot and produce gray mold. Gradually spread to the young melon, the top of the melon strip is chlorotic and watery, softened and atrophied, and finally rotted. Sometimes black sclerotia grows on the melon. The bacteria overwinter on the soil or sick bodies with sclerotia or conidia. In the second year, conidia spread by airflow. It can occur at 4-22 degrees Celsius, but the suitable temperature is 17-20 degrees Celsius, and the relative humidity of the air is more than 93%.
The following measures are mainly taken to prevent gray mold: 1 cultivate disease-free and strong seedlings. First, 2-3 weeks before planting, 40 ml of formalin and 2-4 kg of water per square meter of bed soil were poured on the bed soil, and the film was disinfected for 4-5 days. Second, 65% of the moldy spirit was used before planting. Wet powder (hereinafter referred to as mefen) or 50% procymidone WP (Speed ​​Keling) 1000 times liquid spray seedlings, seedlings transplanted with drugs, high ridge or half-high ridge cultivation, and cover the mulch; Watering should be done on a sunny morning. Spray water on the mold before the water, or spray the shed, so that the temperature is 35-38 degrees Celsius, and the air is drained after 1 hour. 2 Clean the field, promptly remove the flowers, diseased fruits, and diseased leaves in the field, and take them out to be buried or burned outdoors. 3 scientific release, closed in the morning to raise the temperature to 32-40 degrees Celsius, at noon and afternoon, the temperature is reduced to 20-25 degrees Celsius, the humidity is 70%-80%, and the wind is released for 2-3 hours in the evening, then the shed is closed to keep the temperature At 12-13 degrees Celsius. If the outside temperature is above 14 degrees Celsius, it can be dehumidified at night. 4 Chemical control, spray the flowers, young melons and leaves with Methylformin or Suclon 1000 times after 4 days of application. Spray once every 7 days and spray 4-5 times.
Transmission Fitting
Transmission hardware fittings are components used in the construction and maintenance of transmission lines for electricity or telecommunications. These fittings are designed to connect, support, and secure the different parts of the transmission line, ensuring proper functioning and reliability.
Some common types of transmission hardware fittings include:
Suspension Clamps: Used to hang the conductors from the transmission towers, providing support and preventing sagging.
Dead-end Clamps: Used to terminate the conductors at the ends of the transmission line, providing support and preventing them from slipping.
Splice Sleeves: Used to join two conductors together, ensuring a secure and conductive connection.
Insulators: Used to electrically isolate the conductors from the transmission towers, preventing electrical leakage and ensuring proper insulation.
Guy Wire Fittings: Used to secure and stabilize the transmission towers, preventing them from swaying or collapsing.
Connectors: Used to connect different components of the transmission line, such as conductors, insulators, and fittings, ensuring a secure and reliable connection.
