What if watermelon is harmed by corn herbicide?

When the stems and leaves of watermelons are sprayed with herbicides by the nearby corn fields, the impact of fog droplets that have drifted over from the wind causes phytotoxicity to occur every year. Light growth spots are damaged and curled. In severe cases, whole plants die. It is still difficult to avoid the current situation of farmers in small areas. Therefore, first of all, we must do a good job of prevention. We can spray the solution to the watermelons several days before we start spraying herbicides in nearby corn fields. We spray them again after spraying on corn fields. If there is no solution to the problem, it may also be sprayed with chlorophyllin, tianfengsu and other foliage fertilizers to relieve or reduce the harm of herbicides. When conditions permit, a paper cap can be placed on each melon (female flower), which can prevent rain from washing off pollen after artificial pollination, and can also reduce the harm caused by the herbicide droplets on melon. The land that had been planted with watermelons in the previous year could be exchanged for the location in the next year. It is better to use grafting to prevent soil-borne diseases such as blight. Before guagua colonization, spraying carbendazim and other fungicides on the melon borer to disinfect the soil. When the melon begins to sit melon or when wilt occurs, bactericide such as carbendazim can be used to prevent soil-borne diseases such as blight.

Access Control System

Access Control System is in the field of intelligent building, meaning Access Control System, referred to as ACS. Refers to the forbidden authority of the "door", is the guard against the "door". The "door" here, broadly speaking, includes all kinds of channels that can pass, including the door for people to pass, the door for vehicles to pass and so on. Therefore, access control includes the vehicle access control. In the application of garage management, vehicle access control is an important means of vehicle management, not for the purpose of charging parking fees, mainly to manage the access of vehicles.
Entrance and exit access control security management system is a new modern security management system, it sets microcomputer automatic identification technology and modern security management measures as a whole, it involves electronics, machinery, optics, computer technology, communication technology, biotechnology and many other new technology. It is an effective measure to solve the important department entrance and exit to realize security prevention management. Applicable to all kinds of confidential departments, such as banks, hotels, garage management, machine room, armory, confidential room, office, intelligent community, factories and so on.
Access control system has gone beyond the simple door and key management, it has gradually developed into a complete access management system. It plays a larger role in the work environment safety, personnel attendance management and other administrative management.
