(1) Selection of varieties with resistance to large spot disease or light leaf spot disease such as Chiza 5, Longza 4, Songza l. (2) Strengthen management of Gaotian. When the autumn leaves turn over, the sick plants are fattened or burned, reducing the source of bacteria. (3) Add compost of organic fertilizer or fermented bacteria to promote the application of active organic (dung) fertilizers for furrows, apply 2500kg per 667m2, and cover soil after the furrows. It can also be sprayed with 800 times of Opal Organic Active Liquid Fertilizer or 500 times of “Easy-Effective†Microorganism Organic Fertilizer. (4) Strengthen agricultural control. Appropriate early sowing, to avoid the peak of disease. Apply base fertilizer and increase phosphorus and potassium fertilizers. We should do a good job of cultivating weeds and soils, remove the bottom 2-3 leaves, reduce the relative humidity in the field, make the plants robust, and increase the resistance to disease. After sorghum harvested, clean the pasture, concentrate the straw, and use the high-temperature fermentation as a compost. Implement rotation. (5) Chemical control. For higher-value breeding materials, 50% carbendazim WP 500-fold or 50% thiophanate-methyl WP 600-fold, 75% chlorothalonil can be sprayed from the end of the heart to the tasselling stage or the early stage of disease. WP 800 times, 25% benzophenone EC 800 times, 40% EKL 800 to 1000 times, agricultural antibiotics 120 200 times, once every 10 days, continuous control 2 or 3 times . Usually before the disease spreads, it can be controlled before and after sorghum tasseling. When the disease rate in the field reaches more than 70% and the diseased leaf rate is about 20%, spraying is started. The types of agents with better control effects are: 50% carbendazim WP, 50% amifenoxone WP or 90% MXC, all added 500 times of water, or 40% of GFMS 800 times. The use of liquid medicine per mu 50 kg to 75 kg, sprayed every 7 days to 10 days, a total of 2 times to 3 times.
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.
How to prevent and cure sorghum
The sorghum spot pathogens overwinter on mycelia. The first infestation and reinfestation of spore germination in the next year may result in heavier damage in July. The year when more than one business is popular is popular, resulting in a large area of ​​sorghum.
