Low fruit setting rate and difficult fruit setting are the most prominent problems in vegetable production in summer. There are four main reasons for this. Flower bud differentiation is hindered This is the primary reason why it is difficult to set fruit in summer vegetables. In summer, the temperature is high, and shade nets should be used to cool the seedlings during the nursery period. The temperature should be maintained at 22 to 28°C to prevent the high temperature from inhibiting flower bud differentiation. After two true leaves in the vegetable seedlings were sprayed with potassium dihydrogen phosphate (300 times liquid) and mixed with more than 1.8% of the mixture of sodium nitroprusside (6,000 times liquid), the growth of the seedlings could be adjusted, and the disease resistance of the seedlings could be enhanced. During the nursery period, depending on the plant growth, it is determined whether spraying the mechanoceptin to control the plant leggy and ensure that the flower bud differentiation at the seedling stage can proceed normally. High-temperature summer vegetables are often seen at high temperatures above 35°C. If the temperature is too high, it will reduce the adhesion of pollen and stigma, affect the pollen germination and the pollen tube elongation rate, resulting in poor pollination and fertilization, resulting in a large number of fruit and fruit off, and produce a large number of malformed fruit. Therefore, strengthening the cooling measures and controlling the greenhouse temperature within the range suitable for the growth of vegetables are the key measures to increase the fruit setting rate of vegetables. Overgrowth of nutrients The small temperature difference between day and night, high night temperature, high soil moisture, and excessive use of nitrogen fertilizer all contribute to the excessive growth of nutrient and reproductive growth. Production can be sprayed with suitable concentrations of midgets and naphthalene acetic acid to control and promote vegetative growth to reproductive growth and transformation. Boron deficiency in the soil, coupled with high temperature, will inhibit the absorption of boron by plants, if the boron is not supplemented, flower bud differentiation is hindered and is not conducive to fruit set. Flowering and fruit setting should be sprayed with 600 times borax or 1200 times the speed of boron, to increase the fruit set rate of vegetables.

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.
Professional 4G PTZ WiFi Camera manufacturer is located in China, including Full Color Night Vision Two Camera,Smart Wifi Zoom Cctv ,360 Degree Ip Wireless Camera, etc. 4G PTZ WiFi Camera,Full Color Night Vision Two Camera,Smart Wifi Zoom Cctv ,360 Degree Ip Wireless Camera,PTZ Outdoor Camera Shenzhen Fuvision Electronics Co., Ltd. , https://www.outdoorsolarcameras.com
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.
