Appropriate selection of varieties should follow the principles of cold tolerance, drought tolerance, negative tolerance, trampling resistance, rooting, and ecological compatibility. Such as the white flower clover, hairy scorpion, alfalfa, etc. of the leguminous family; perennial rye, sage, bluegrass, etc.
Grasping the management of green manure is an organic fertilizer, which generally does not require special management, but fertilization and irrigation can greatly increase the yield of green manure. Superphosphate is used as the base fertilizer, applying 5~10 kilograms per acre; one year or two times of topdressing, mainly nitrogen fertilizer, applying 10~20 kilograms of nitrogen fertilizer per acre per year, spraying or foliar spraying.
Timely pressure should be selected to turn over when green manure yield is high and nutrient accumulation is high to improve the fertilizer efficiency of green manure. Generally, the leguminous green manure is in the flowering stage to the flowering stage; the gramineous green manure is in the heading stage; the cruciferous green manure is in the upper flowering stage. After turning over, it should be timely flooded to accelerate decomposition and increase the conversion rate of green manure. Timely castration should be castrated in time according to the growth situation. In the year of planting, it is best not to cut in the first few months. When the roots are stable and about 30 cm high, castration begins. The height after castration is about 10 cm. Different varieties, the number of castrations varies, generally 2 to 3 times of castration throughout the year, the number of castrations with fast growth is high, and vice versa.

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.
