Onion growth requires higher soil moisture and lower air humidity. Scallion in the germination phase needs more water, to ensure that holding the soil moist, in order to ensure that the seeds germinate and unearthed, the seedling growth in the early stage, see the surface see dry see wet, into the seedlings growth period, should increase the number of watering and watering. After the planting period, the soil moisture was sufficient and the seedlings were quicker, but the soil was too wet to cause rot and yellow leaves and affect the growth. Therefore, it should be based on cultivation and cultivation to promote root growth. During the formation period of light blue, more water is needed to keep the soil moist, so as to improve the quality and yield. Reduce irrigation prior to harvest, prevent love greens, and improve the storage of green onions.

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.
