First, due to the wide distribution of tree roots, absorption of water and nutrients in the fibrous roots, therefore, fertilization should be around the root, not too close to the trunk.
Second, the roots of large, widely distributed trees, fertilization should be deep, the scope should be large, such as pine, ginkgo, stinky, Acacia, etc.; root shallow trees should be shallow fertilization, range should be small, such as Fatong, Amorpha fruticosa and so on.
Third, organic fertilizer should be fully fermented and cooked, and avoid using raw manure. Fertilizers must be powdered and should not be applied in blocks.
Fourth, after fertilization (especially topdressing), must be timely and adequate irrigation, so that the fertilizer infiltrated into the soil.
5. Fertilization should be carried out when the weather is fine and the soil is dry. In rainy days, due to the slow absorption of water by roots, not only nutrients are not easily absorbed, but nutrients are also washed away by rain, causing waste.
Sixth, sand and slopes are prone to loss of nutrients, and fertilization should be deeper.
7. Nitrogen fertilizers have a strong mobility in the soil, so the shallow application can penetrate into the root distribution layer and be absorbed by the trees; the mobility of potash fertilizer is poor, and the mobility of phosphate fertilizers is even worse. It is advised to apply them deepest to the root system.
8, base fertilizer due to slower fertilizer effect should be deep, top dressing fertilizer effect is faster, it should be shallow Shi.
Nine, foliar spray must be sprayed when spraying, this is conducive to absorption. Foliar fertilizer should strictly control the spraying concentration so as not to burn the leaves. Spray better on cloudy days or before 10 a.m. and after 4 p.m.
We may usually see monitor devices in private cars, and they are called the car cameras. Today I'd like to introduce you another type of car cameras, the car cameras for vehicles with special purpose such as police cars, school buses, tanker trucks, container truck, Taxies, buses... Generally Speaking, the monitor devices used for these vehicles need to be much more stable so multiple car camers should be combined together to reach that monitor effect, then a monitor system formed, and we call this kind of monitor system the Vehicle Surveillance System(Car Security Camera System).
The Vehicle Surveillance System(Vehicle Security Camera Vehicle Camera Systems)(a three-layer networked comprehensive monitoring system), composed of a vehicle terminal, a transmission network, and a monitoring center, mainly provides the functions such as the vehicle anti-theft, anti-robbery, driving route monitoring, real-time wireless transmission of video images inside and outside the vehicle, rapid response to accidents, call command and so on, so that the problem of dynamic management of existing vehicles can be solved.
So what advantages of the vehicles with Vehicle Surveillance System(Car Surveillance Camera)?
1. Bank Money Transport Trucks, Tanker Trucks, and other Valuables Transport Vehicles: anti-theft and anti-robbery
2. Passenger Vehicles such as Buses, Long-distance Buses... : ticket anti-theft, passenger anti-theft and anti-robbery
3. Ambulances: patient treatment process monitoring and video recording, which can be as the evidence once the medical malpractice dispute happened
4. Police Cars, Fire Trucks: case handling process video recording, which can be as the material and evidence of the investigation after
5. Environmental Monitoring Vehicles: record the environmental pollution scene (which can be as the prosecution evidence) and transmit real-time informations to the Environmental Monitoring Center meanwhile(which can help the Environmental Monitoring Center take effective measures on the pollution source right away)
6. Trains, Steamships... : security monitoring, real-time recording
7. ...
In conclusion, Sanan Technology has been studying the Vehicle Surveillance Systems(Car CCTV Camera) for over 10 years, and the Vehicle Surveillance System has become our key product line gradually. Sanan has accumulated rich experience in various Vehicle Surveillance Systems Solutions and belive us, we are specialized!
