Streptomyces is a malignant mushroom produced by edible fungi in summer and autumn, which can cause devastating pollution to edible fungus production. Streptomyces is very viable, has a rapid growth, and has a strong ability to spread. The mushroom field after the outbreak of Streptomyces is generally difficult to use normally. This kind of bacteria rarely occurs at low temperatures (below 20°C). The conditions that occur are high temperature, high humidity (above 95% relative humidity) environment.
The main prevention and control measures are: Cultivation of edible fungi in the summer, cornmeal should be used with caution when preparing cultivation materials, and it is best not to use or use it in small quantities (not more than 1%). High levels of cornmeal can easily attract Cladosporium; Second, when preparing culture materials , Add appropriate amount of "Mushroom Master" brand "Mushroom Dr. First Aid 120" sterilizer, can effectively control the occurrence of Streptomyces, Dr. Mushroom mixing ratio is: Dr. 400g each mushroom can be mixed dry Material 4,000 pounds. Dr. Mushroom's method of adding ingredients in the culture medium is to mix all the raw and auxiliary materials first, and then dip each bag of mushroom with water to about 100 pounds. Sprinkle with a water scoop or spray with a sprayer and mix in the culture medium immediately. , Pack it as soon as possible after bagging, then immediately pot sterilization. Keep in mind that the time from bagging to retort sterilization should not exceed 5 hours (because the broth is supplemented with some bran and other nutrients, it is suitable for the occurrence of all kinds of microorganisms and bacteria at a normal temperature of around 30°C) The packaged bacteria will be immediately heated on the pot to the boiling point with the fire; the third is the germination period, as far as possible to avoid the rainy season or keep the room ventilated, dry, lime and damp the ground. Mushroom room space interval 3-4 days use the "mushroom master" brand chain spore smoked fumigation once, or with "mushroom master" chain contusion watered 100 kg per bottle spacing interval 3 days spray mushroom house; four is like a bottle ( Bags) When the fast-growing white flocculent hyphae or white conidia balls are found in the inner and bottle mouths (bag mouths), they should be picked out in time, and then 30 kilograms of water per bottle of the streptomycin be blended into a liquid, and then The infected bacteria bags will be picked up and put into the drug solution. Scroll and take it out. When developing into an orange balloon, it is difficult to control. Once the bag mouth appears a red or white chain. When the fungus spores can only be soaked with 20 pounds of water sprayed by Somite, it is time-consuming and labor-intensive to handle. Remember: Do not arbitrarily say that the fungal colonies infected with Neurospora are randomly discarded at or near the entrance of the mushroom house to avoid causing new sources of infection. Then the whole mushroom house is sprayed with the “Mushroom Master†brand propidium saccharin as an all-round spray once, and sprayed once every 3-4 days, or sprayed with 60 pounds of water per bottle with Velcro.
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.
