At present, the jujube tree gradually sprouts fruit branches, draws flower buds, and produces flowering results. As the jujube tree has many branches and a large amount of buds, it needs to consume a large amount of nutrients. When the young fruit is grown after the flower is cut, the tree vigor is very weak, which is not conducive to stabilizing the fruits, and must be applied in time to stabilize the fruit. . The main fast-acting instant nitrogen and potassium fertilizers are the main components. For trees over three years of age, 0.75-1 kilograms of urea and 0.5-0.75 kilograms of potassium sulfate are applied to each tree. After the rain, they are evenly spread on topsoil beneath the canopy, or against fresh water or marsh. After 80-100 times of decomposed human or animal manure water or mash, evenly applied to the top soil under the canopy, it is better to completely penetrate the soil into the soil.
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.

Fuvision's autonomous automatic PTZ intelligent tracking enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically controls the PTZ Camera to rotate the PTZ in all directions and zoom the lens. It also conducts visual oriented automatic tracking for the locked moving target to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the guards 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.
