Cherry radishes are more red and bright in appearance, small and attractive, and the price is much higher than ordinary radishes. Therefore, many radish growers also like this new type of radish. But some farmers asked, cherry radishes are delicious, but are they good to grow? Cherry radish has a short growth period, wide adaptability to the soil, and short fleshy roots, and the soil requirements are not too strict. Therefore, as long as you master the correct planting method, you can grow delicious cherry radishes at home. Cherry radish planting 1. Fertilization as a border First, the land to be planted is deep-turned and leveled. The cherry radish has a short growth period and mainly uses base fertilizer. Generally, 2,000 kg of decomposed farmyard manure is applied per acre to make a high border with a border width of about 1 meter. 2. Sowing Pour water before planting, and spread the seeds on the border surface after the water seeps, and cover the soil with a thickness of 1 cm after planting. If drilled, the seeding depth is 1.5 cm, the drill row spacing is 10 cm, and the plant spacing is 3 cm. Cherry radish planting tips 3. Field management The growth period of cherry radish is short and the management is relatively simple. After the seedlings are completed, the seedlings will be thinned once at the cotyledon stage and 2~3 true leaf stages. The seedlings will be fixed when 4~5 true leaves, and the seedling distance should be 3~4 cm. During the growth period, keep the field moist, not too dry or too wet. Planting in autumn, there are many weeds, weeding should be cultivated to keep the soil loose and prevent soil compaction. 4. Harvest Cherry radishes generally grow for 25-30 days. If the temperature is too low, the growth time will be slightly longer. The fleshy roots are beautiful and bright, and can be harvested when the diameter is about 2 cm. If the harvest is too late, root cracks and chaff cores will appear, resulting in lower quality.
What is Battery Mini Camera
Micro camera is a product of modern high-tech, also known as micro monitor. It has the characteristics of small size, powerful function and good concealment.
Some cameras also use video transmission lines for synchronous power supply without external power lines.

Wireless
Wireless equipment is used stably in domestic wireless environment. The micro wireless surveillance camera has the characteristics of high stability, high speed, long distance and multi-point testing. It can play a huge role in the fields of environment, energy, construction, transportation, medical treatment, industrial machine condition monitoring, etc., especially when the cabling is complex, the cabling cost is high, the long-distance and large-scale transmission of data and the mobility demand is high. Secret Video camera
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.
