Mid-August to mid-September is the peak period of citrus leaf miner.
Control methods
Controlling the shoots by shoots, unifying the shoots The dominant factor affecting the occurrence of leaf miners in summer and autumn is food, which is mainly the young shoots of citrus. Therefore, the fundamental measure to control the source of insects should be to control the shoots and unify the shoots. When the tip is put, it is necessary to keep the whole point of zero, to stay early, and to stay less for the principle of letting go. The criterion for the tipping is that 70% to 80% of the plants in the garden have their shoots removed. When each tree has 70% to 80% of shoots, it is wiped clean at one time and then tipped.
Chemical control can be used as a control index of citrus leaf miner when the damage rate of citrus shoots reaches 20%. Pesticides for controlling citrus leafminer are 98% Bataan WP 1500-2000 times, 20% Diflubenzuron No. 1 suspension 3000-4000 times, 2.5% deltamethrin 3000-4000 times, 2.5% Kung Fu EC 3000 ~ 4000 times liquid and so on. At the same time, the adults of the citrus leaf miner inhabit the grass in the orchard or near the nursery during the day and come out at dusk. Therefore, the prevention and control of leaf miners should always clean the weeds around the orchard or nursery. Spraying should be done at dusk to get a multiplier effect.
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.
