Cucumbers do not need to remove roots?
There are two hazards to removing a cucumber if it does not remove the root. First, easy to leave the bacteria, many cucumber plants suffer from root diseases, if the root system is not completely removed, the pathogen will continue to stay in the soil, endanger the next vegetable. Therefore, when the cucumber is pulled out, all the roots must be pulled out. If the soil is dry, you can pour the water before the garden to moisten the soil. If necessary, excavation can be taken to avoid leaving roots in the soil. In addition, before pulling out the garden, it is best to make a mark at the site of the diseased plant. After the garden is pulled out, the sickle should be treated with quicklime or liquid medicine to eliminate the germ. Second, it is easy to leave the root-knot nematode on the roots in the soil, there is a root knot nematode greenhouse, a large number of root-knot nematodes will attach to the roots of cucumber, if the rooting is not complete, will continue to stay in the soil, under the harm茬 vegetables. Therefore, when cucumbers are pulled out, they can use this opportunity to completely bring out root knot nematodes attached to the roots. Therefore, when removing a garden, cucumber must be thoroughly cleaned.
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.
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.

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.
