Loofah main disease prevention and control points

Anthrax disease occurs from the leaves of the seedling stage, and the lesions are nearly round, dark brown in color and have rosy patterns. The later lesions developed into irregular shapes; the lesions on the petiole were yellow-brown, oval-shaped, and the lesions were sunken.

Brown spot mainly damages the leaves, and the lesions are brown to gray-brown. The lesions are round or irregular. There are sometimes faded green to yellow halos at the edges of the lesions. The lesions are dry at the late stage and easily broken.

Leaf lesions on leaf blades were nearly round brown or dark brown patches. The lesions on the melon strips were round or irregularly shaped lesions with brown edges and grey white areas. The lesions on the stems are elliptic to spindle-shaped, brown on the edges, gray-brown on the middle, and sometimes the lesions overflow with amber-colored transparent gums, and the stems of the stems are dead. The disease can also harm loofah flowers, which can cause the water edge of the loofah flowers to rot. In severe cases, it may flow like pus and sometimes smell. Late dry, dry burnt flowers, petals are not fresh. The onset of young melanocarpus was mostly black rot.

After raining in the rain and snow, the humidity in the shed was high and the three diseases were serious. During the prevention and control, it is necessary to reasonably control the temperature and humidity in the shed, implement rotation for crop rotation, increase application of organic fertilizer and phosphorus and potassium fertilizer, strengthen ventilation, increase translucency between plants, and reduce the application of nitrogen fertilizer.

To prevent anthrax, it can be sprayed with 80% anthrax 800 times or 25% carbonate 500 times; control brown spot can be sprayed with 50% for 600 times, or 47% for Garrett 600 times; Sprinkling can be sprayed with 75% chlorothalonil 500 times solution or 1200 times power or 100 times 100g. At the same time, when these three diseases are controlled, 50% of the protection work can be sprayed with 1200 times liquid and DT600 times liquid together.

Indoor PTZ Camera

What is Indoor PTZ Camera

PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.

PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.
Automatic tracking is divided into three types: one is through embedded video encoder, also known as intelligent visual server; the other is PC software; the other is to directly write the tracking algorithm to DSP chip, and then design the DSP chip as a hardware circuit on the high-speed ball motherboard, and the high-speed ball is directly read. Among the three types, the third type is used most in the current market.
The intelligent vision PTZ automatic tracking and monitoring system consists of an intelligent vision server (responsible for intelligent analysis and command) and a high-speed spherical camera (responsible for tracking targets). The automatic PTZ intelligent tracking function enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically control the PTZ camera to rotate the PTZ in all directions and zoom the lens, and perform visual oriented automatic tracking for the locked moving target, so as to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the security personnel can see the information more clearly, It can also be used for obtaining evidence afterwards. The automatic PTZ tracking module makes up for the narrow field of vision of fixed camera monitoring, which is an essential function of a perfect security monitoring system.
The intelligent vision PTZ automatic tracking and monitoring system has the target analysis function, and is equipped with a high-resolution camera, a large magnification optical zoom lens and a high speed PTZ, which can automatically capture suspicious targets quickly and accurately. By setting the preset position intelligent vision PTZ automatic tracking monitoring system, the preset position scanning, automatic cruise and other functions can be realized, and many special requirements of intelligent monitoring can also be realized. In addition, the intelligent vision PTZ automatic tracking and monitoring system also has the advantages of beautiful appearance and strong concealment, so it is very suitable for public security intelligent monitoring applications in airports, squares, rail transit, villas, government administrative units, military regions, museums and other types of places.

The automatic PTZ tracking and monitoring system integrates optics, electronics, machinery, information processing and network, and is composed of camera, power transmission, motion control device, image analysis, recognition, compression and communication based on high-speed parallel processing. It has the functions of video camera, position control, orientation and lens preset, moving object detection, recognition and tracking, flame and smoke detection and alarm, etc. It can be widely used in buildings, banks, airports, stations, customs, transportation, power, factories and mining enterprises and other security monitoring occasions.
