There are many reasons for fruit cracking. In summary, there are three key factors: nutrient absorption, water management, and peel thickness. Therefore, prevention of fruit cracking needs to start with the following aspects:
Strengthen the management of orchard fertilization: the application of biological stimulants can improve soil fertility and strengthen tree vigor, and compound fertilizer can promote the balanced and coordinated development of fruit flesh and peel. The cell wall density of the peel is high, and the flexibility of the peel is enhanced, which can reduce the occurrence of fruit cracking.
Keep the soil moisture balanced: moisture has a great influence on the growth and development of citrus fruits. It is strictly forbidden to strengthen irrigation after the fruit cracking is not seen. To prevent fruit cracking, the daily water management of the orchard should be strengthened and scientific water use should be implemented. The soil water holding capacity is generally maintained at 60% to 80%.
Strengthen the pruning of the tree body: timely pruning the citrus tree body appropriately. Before heavy rain or flooding, the tree can be treated with root cutting to reduce the probability of fruit cracking.
Citrus fruit cracking generally occurs from August to September. It is the period of citrus fruit expansion. The majority of fruit farmers should prepare for drought in time to reduce the occurrence of fruit cracking. The main methods to prevent citrus fruit cracking in production are:
First, when irrigating after a prolonged drought, the method of "small amount and many times" should be adopted to avoid the occurrence of citrus cracking caused by large irrigation after a prolonged drought.
The second is to do a good job in fruit thinning to ensure normal fruit growth and reduce fruit cracking.
The third is to avoid sunburn and fruit cracking caused by direct sunlight, and keep the fruit with 3~4 leaves.

The Network CCTV Wireless Security Camera
Compared with wired cameras, wireless security cameras are less invasive to your home, so they are easier and faster to set up. No need to drill through walls or ceilings. Wireless cameras are also more flexible than wired systems because they are not as constrained as wired systems.
The biggest disadvantage of a wireless Camera System is that it is completely dependent on the strength of your Wi-Fi connection. Any interruption or weak signal can mean that you may lose connection to the system, resulting in the loss of the film, which can be critical

Working principle of camera
The working principle of the camera is to reflect the light to the sensor, convert the signal captured by the sensor into a digital signal, and finally send it to the computer to display the image. Then the camera can capture the static and dynamic images in the picture.
The sensor of the camera is the most important part. It can capture light and convert it into electrical signals. There are many types of sensors, the most common are CCD and CMOS sensors, which can be used to capture images.
The internal circuit of the camera will convert the signal captured by the sensor into a digital signal and send it to the computer. The computer uses these signals to display images, or it can save images to the hard disk drive.
If the camera is not connected to the network, it will not be able to achieve real-time monitoring, but the camera will still work and save the pictures and videos taken. If we need to view, we can only remove the memory for viewing.
The smart camera can also support remote monitoring. You can remotely view the real-time image of the camera through your mobile phone or computer. Users can view the image of the camera anytime, anywhere, to better protect the security of your home or office.
