First, the symptoms
Symptoms first appear in the upper leaves of the growing point of the plant. During onset, the leaves are distorted and shrunk. The petiole and veins are hardened and easily broken. The buds and young fruit fall off and the growth of the plants stops. This has a great influence on the flowering of the pepper. (Typical characteristics of the disease when it is diagnosed in the field are different from those of viral disease. The distorted and wrinkled leaves have no mosaic or yellowing phenomenon).
Second, the cause
The main reason is caused by the lack of boron in plants. Continuous cropping, greenhouse cultivation of multiple physiological diseases, soil acidification, boron is a large number of loss, or excessive application of lime are likely to cause boron deficiency. The soil is arid, organic fertilizer is used less, and boron deficiency is also likely to occur under high temperature conditions. Excessive application of potash will also inhibit the absorption of boron by plants.
Third, control methods
1. Adding organic fertilizers: In particular, we need to apply more compost to produce more manure. The manure fertilizer contains more boron, and it can fertilize the soil, enhance the ability to retain water and fertility, reduce drought damage, promote root expansion, and promote the absorption of boron by plants. Prevent soil acidification or alkalization.
2. Soil improvement: Once the soil is acidified or alkalized, it needs to be improved. To strengthen management to prevent soil from drought or excessive humidity, otherwise it will affect the absorption of boron in the root system.
3, increase boron fertilizer: When the symptoms of boron deficiency, should be promptly sprayed to the foliage 0.1%? 0.2% borax solution, once every 7? 10 days, continuous spray 2-3 times. Can also be applied per acre borax 0.5 ~ 0.8 kg watering.
The Zoom Dome Camera/ Zoom Dome Security Cameras/ Dome Zoom Camera 1080p/ Zoom Dome CCTV Cameras/ Zoom Dome Camera HD/ Zoom Dome Camera Waterproof belongs to both the Zoom Camera and the Dome Camera. I have introduced the Dome Camera before, this time let me introduce the installation skills and the maintenance skills of the Dome Camera for you.
The installation skills of the Dome Camera
1. Get familiar with the product performance
Having gotten the Dome Camera, engineers and users should be familiar with the technical parameters of the Dome Camera, such as the input voltage, power, functions, etc.
2. Check
Before the installation, the Dome Camera should be tested and adjusted to keep the camera working normally.
3. Installation method
Before the construction, according to the environment, safety, and aesthetics, these installation methods can be adopted, such as the wall mounting or hoisting.
4. Installation angle
The installation angle of the Dome Camera can directly affect the scope of the monitoring image, so the Dome Camera should be installed according to the field requirements. For instance, if the Dome Camera is installed at the place less than 6m to the area entrance, the camera angle should be 30°-60°; if it is installed at the cash register, the camera angle should be at ±15°-20°. In short, the backlighting should be avoided when installing the Dome Camera, so as to meet using requirements.
5. Video interface processing
The video signal output port, power input port, and control signal port of the dome camera are very important. When installing, try to do the waterproof and oxygen-proof dealing with the these ports, to avoid those phenomenon happens in the future, such as being unstable, uncontrolled, or even no image display.
The maintenance skills of the Dome Camera
The Dome Camera generally need to work continously for 24 hours, so well maintain the Dome Camera can extend its using life, and ensure the stability of the camera's image effect. The following points should be paid attention to:
1. Pay attention to the stability of the voltage of the Dome Camera, otherwise, it will affect the image effect and even cause the camera damage;
2. Always check whether the wire is damaged or aging, to avoid the abnormal situations;
3. Avoid the long-time direct sunlight or strong light, to avoid damage to the camera CCD;
4. Clean the Dome Camera frequently, such as the camera shell. Try not to open the case, if you need to open it, power off first. Create the Dome Camera files for the inspection and testing in the future.
All in all, I hope that the introduction about the the installation skills and the maintenance skills of the Dome Camera can help the Dome Camera and Zoom Dome Camera users better use their cameras.
