One is the high standard of the planting field. The nursery is generally 10-20 meters long, 1.2 meters wide bed, 0.4 meters wide, 0.2 meters deep ditch around to open a good ditch to prevent drowning bed, causing root dead. For the vegetable field of different vegetable families, the seedling field is selected to apply 200 kg of fully decomposed livestock and human feces per 10 square meters. If chicken, duck and other hot organic fertilizers are used, it must be fully fermented; plant ash 20-30 kg, phosphate fertilizer 3- 5 kg, ternary compound fertilizer 2-3 kg. After the earthworms were evenly plowed, the water was leveled and fully watered and sprayed with a 1:400 solution of 75% chlorothalonil. The second is to achieve "three good and one high" implant. The wintering seedling planting work needs to be done in three ways: that is, plastic greenhouses and small sheds are of good quality in order to facilitate the preservation of the wintering seedlings after the planting; the second is that the weather is good, the planting is sunny, and the cloudy day is the second, and the rainy days are not False planting; Third, the soil is good. In addition to the preparatory work of the planting field in addition to the planting field, the plant can not be watered when it is planted, and the soil is as dry as possible. A height is a high standard of planting, planting and planting, two plants, spacing 6-7 cm, spacing 12-15 cm; plant per plant, plant spacing 10 cm. On the first night, the seedbed was moistened with a 1:400-fold solution of 75% thiophanate-methyl liquid, which was beneficial to lifting. When prospering, plant and pour 20 grams of potion on each side, covering the small arches. The third is to manage the arch membrane. In November, the seedlings were planted on a false basis, and during the seedling period, the greenhouses and small arches were managed according to the weather. The weather was good. During the day, the small arches were covered with the film. At night, the surface of the film was removed and the cover of the house was covered. The weather was not good. During the day and at night, the cover film was used to open the ventilation window at both ends of the arch and in the middle.
What is 4G PTZ WiFi Camera
Camera, also known as computer camera, computer eye and electronic eye, is a video input device, which is widely used in video conference, telemedicine and real-time monitoring. Ordinary people can also talk and communicate with each other through the camera on the network with video and voice. In addition, people can also use it for various popular digital images, video and audio processing.
The 4G intelligent camera, also known as 4G camera and IPC, is mainly used for security video surveillance. Its feature is that the 4G communication module is built into the universal surveillance camera, allowing the camera to be directly connected to the network through the base stations of the three operators, breaking the limitations of the original deployment of network cables or WIFI connection, so as to achieve the purpose of remote monitoring.

At present, the functions of smart cameras mainly include video monitoring, voice dialogue, security alarm and video review.
Video surveillance
Video surveillance is the core and basic function. The current intelligence is that the mainstream resolution of cameras is 1080P HD, which requires a high level of network. Most home cameras transmit data through WiFi, which is convenient to move. Some stores also install such cameras, which are mainly used to monitor the main points such as the cash register. This kind of camera that does not need to move can use the network cable, and the signal will be more stable.
Voice conversation
Most cameras on the market are equipped with the function of voice conversation. Users can directly have voice conversations with their families through the APP. Of course, although many devices on the market support this function, noise elimination, uneven echo and other situations still occur frequently and need to be improved continuously.
Security alarm
The security alarm function is mainly used to record vibration, special noise and other vibrations, and alarm through APP.
Video review
At present, smart cameras on the market all provide the function of video review, but most of them only provide the function of alarm review, that is, the video recorded after the alarm occurs can be reviewed, and the rest of the time can not be viewed, and it is a paid function. Few manufacturers can provide uninterrupted video retrieval function. The reason is simple: the cost of video storage server is too high. Video belongs to large flow files. If you want to achieve uninterrupted recording, storage and review, the cost will be many times or even dozens of times higher.
4G intelligent camera
The deployment of wired network is troublesome or the coverage of WIFI is limited. For example, security monitoring of mature commercial offices or new indoor and outdoor blank areas in residential areas, video monitoring is required for outdoor construction sites, and 4G intelligent cameras are required for the deployment of wired network is troublesome and scattered.
In the middle and late November, it is the best time for the veggies of peppers, eggplants and other vegetables to be planted. The wintering and planting of vegetables—the period of slender seedlings should do the following:
