The appropriate load is the amount of load that can ensure continuous and high yield of apple trees. It requires fruits, branches and leaves to reach a certain proportion. A large number of practical investigations have proved that the ratio of large fruits and fruits represented by Red Fuji is 4 to 5:1 and the ratio of leaf to fruit is 50 to 60:1. The ratio of medium fruit to fruit is 3:1, and the ratio of fruit to fruit is 30-40:1.
The above are the technical standards for apple blossoms and fruit thinning fruits that reach into the full fruit period. In production, according to tree vigor and cultivation level, Jiaodong growers generally require the production of mu in the range of 2500-5000 kg, and require a relatively large fruit size, generally larger than 200 g for large fruit and 150 g for medium-sized fruit.
According to the above requirements, calculating the number of retained fruit, plus an insurance factor of 10% to 20%, is the amount of fruit left in the actual fruit thinning. If the Red Fuji varieties are to be planned to reach 3,000 kilograms, the calculation method for the actual number of preserved fruits is (30005)+(3000510% to 20%)=16500 to 18,000 (pieces). After determining the amount of fruit left, determine the amount of fruit left in each plant based on the strength of the tree and the size of the canopy.
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.
