Second, black skin black heart: The main reason for the emergence of radish black skin black heart during planting is that the soil is hard, the air permeability is poor, and the microbial activity caused by the application of unripe manure is strong, resulting in the lack of oxygen in its roots.
Third, the cracking: the main reason for the cracking of the radish root is the uneven water supply during the growth of the fleshy root, caused by the first dry and wet.
IV. Delivery: The main reasons for the delivery of radish are the old seed array, the destruction of radicles, shallow soil layers, soil compaction, and the presence of gravel and tile in the soil. This is caused by inadequate basal fertilization or improper fertilization.
These are the reasons for the poor growth of fleshy roots that may occur during the cultivation of radish. If these phenomena are found, appropriate measures should be taken to ensure high quality and high yields.

4G Mini Camera Structural components
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
Some cameras also use video transmission lines for synchronous power supply without external power lines.
