Upon inquiry, it was learned that the farmer had applied a large amount of uncomminuted pig manure to the ground. Due to the high temperature in the shed, the secondary decomposation of pig manure occurs, and the air nitrogen content increases, causing burning of seedlings and chlorosis of the bottom leaves of the eggplant plants. It is recommended to strengthen management, pay attention to the temperature of the greenhouse, strengthen ventilation, and the temperature difference between day and night should not be too large. If there is an epidemic disease, carbendazim can be used for control.
The 300mm LED traffic signal light refers to a signal Traffic Light with a light-emitting scale of 0. The light source is LED. 300mmLED, traffic signal lights have two units as a group of LED traffic lights, including red and green static combination, red and green dynamic bold countdown non-motorized combination, red, yellow and green non-motorized combination, red and yellow two green arrow combination, etc., traffic LED pedestrian signal lights, this It is a 300mm red and green pedestrian pattern signal light, using LLED lamp beads, and the shell can be made of aluminum or industrial plastic. It can be configured according to the actual traffic environment requirements. It is usually used for pedestrian crossings and pedestrian signal light poles, pedestrian signal light control mechanisms, and adult pedestrian signal light systems. The dynamic pattern shows the humanization of this traffic light, and it is also the signal light of the new urban image.
Traffic LED pedestrian signal light, this is a 300mm same color pedestrian countdown pattern signal light, red and green alternately displayed, using LED lamp beads, the shell can be made of aluminum or industrial plastic, configured according to the actual traffic environment requirements, usually used for crosswalks and pedestrian signal light poles , Pedestrian signal light control mechanism Adult pedestrian signal light system, dynamic pattern, more humanization of this kind of traffic light, it is also a new type of city image signal light, compared with the above-the model is more effective, can inform the time, more suitable for busy people flow Intersection.
