The hybrid small cultivars cultivated by Guangdong and Guangxi, suitable for four season cultivation, and resistant to heat and humidity are selected. 1 Seeding 1.1 Seedling tray preparation A 37cm × 25cm × 7cm flat bottom watertight plastic tray is used for seedling cultivation. The seedling tray * is blue or black. 1.2 Nursery substrate preparation Sponge blocks are generally used to raise seedlings. Cut the sponge to 29cm × 20cm × 2.5cm, which is slightly smaller than the size of the seedling tray, and then cut into 2.5cm × 2.5cm small pieces. The “ten†-shaped incision in the middle of the small sponge is about 2/3 of the depth of the sponge. Each sponge grows 96 Strain. 1.3 Seeding Soak the sponge block first, wet the cabbage and cabbage seeds with a small toothpick and stick 2-3 seeds in the cross cut of the sponge block, then add water to the seedling tray with a water depth of about 1 cm. After sowing, stack the seedling trays in a cool and ventilated place, pay attention to maintaining the humidity on the surface of the sponge. If necessary, spray water on the surface of the sponge 1-2 times a day until budding. 1.4 Seedlings and watering nutrient solution About 5 days after sowing, the true leaves of the seedlings showed green time seedlings, and 1-2 seedlings were selected for each sponge block. In order to cultivate strong seedlings, after the true leaves turn green, the water in the seedling tray can be as dry as possible, and the prepared nutrient solution can be sprayed so that the nutrient solution can be dipped on the surface of the sponge block to promote the rapid growth of the root system. 3 days before transplanting seedlings. 2 Colonization 2.1 Preparation before planting Prepare the cultivation bed, check whether the bed trough is leaking, and mix the nutrient solution for the circulating mixing test. 2.2 Colonization When planting, tear the cabbage seedlings and pakchoi seedlings together with the sponge blocks from the seedling tray and insert them into the planting holes. After the planting is completed, spray the sponge blocks with water once, and then adjust the automatic liquid supply timer to start the nutrient solution. Automatic cycling. In order to ensure the whole seedlings, waterbed vegetable seedlings should be sprayed with water 2-3 times a day after 2-3 days after planting, and the water spraying should be stopped after the root system reaches the nutrient solution.

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.
