Reasonably topdressing strawberries into the fruit-picking period usually topdresses for about 20 days, and topdressing can be combined with irrigation. This period is the first harvest of strawberry fruit is basically completed, the second batch of inflorescence is about to appear in stages, should be appropriate fertilizer, fertilizer with quick-acting nitrogen, potassium fertilizer-based compound fertilizer, can be applied 15 kg per acre.
Plant cleaning removes old leaves, diseased leaves, and stolons in time to reduce nutrient consumption and often retains 4 to 5 functional leaves. Appropriate sparse fruiting and thinning, sparse fruiting stems are too short, flowers are small, fruits are not hypertrophy, and fruits have deformed fruit when large.
Temperature and humidity control to catch the fine weather for necessary ventilation and humidity, increase light. In the low temperature season, the temperature in the shed is kept as much as 20°C to 25°C during the day and 5°C at night. Humidity has a great influence on strawberry flowering pollination, high humidity, pollen germination rate is low, often increase the rate of small fruit and malformed fruit, so try to keep the relative humidity within the shed at 50% to 60%. At the same time, bees are added in time to ensure pollination quality. After the spring begins, the temperature gradually rises and the temperature inside the shed warms up. At this time, as the temperature rises, the amount of ventilation is gradually increased to prevent the temperature in the greenhouse from being too high. Otherwise, the strawberries will become smaller and become more acidic.
The Zoom Bullet Camera means that the Zoom Bullet Camera/ Zoom Bullet Network Camera/ Waterproof Zoom Bullet Cameras/ Zoom Bullet Camera CCTV/ Zoom Bullet Surveillance Cameras/Infrared Bullet Zoom Cameras belongs to not only the Zoom Camera but also the Bullet camera. We have introduced the basic features of the Bullet Camera before, so this time let me introduce the maintenance skills of the Bullet Camera(including th Zoom Bullet Camera)for you.
The maintenance skills of the Zoom Bullet Camera
1. The basic conditions to maintain the Zoom Bullet Camera
The basic maintenance conditions required for the normal equipment maintenance of the Zoom Bullet Camera
system are the "four complete". That is, the complete spare parts, complete accessories, complete tools, and
complete instruments.
1) Complete spare parts
Generally speaking, the corresponding spare parts library(which mainly stores some important equipment that is not easy to repair immediately after damage, such as the Bullet Cameras , lenses, monitors, etc.) must be established for the the maintenance of each system. Once these equipment fails, the system may not operate normally and must be replaced in time. Therefore, a certain number of spare parts must be available, and the inventory of the spare parts library must be continuously updated according to the repairability of the equipment and the characteristics of the operating cycle of the equipment.
2) Complete accessories
Accessories are mainly the additional configuration of the various discrete components and modules in the equipment, which are mainly used for equipment maintenance and to prepare more accessories would be better. The commonly used accessories mainly include various integrated circuit chips and circuit discrete components, required by the circuit. Other larger equipment must be equipped with the certain functional modules for the emergency use. In this way, a lot of expenses for updating equipment can be saved with a small investment.
3) complete tools and testing instruments
The Zoom Bullet Camera must be equipped with the common maintenance tools and inspection equipment, such as various pliers, screwdrivers, electric test pens, electric soldering irons, adhesive tape, multimeters, oscilloscopes, etc. If necessary, the user should also make some testing tool such as the simulated load.
2. The specific maintenance skills of the Zoom Bullet Camera
1) Dust and clean the equipment once a quarter to ensure the normal operation of the machine. Meanwhile, check the ventilation, heat dissipation, dust removal, power supply and other facilities of the monitoring room. The outdoor temperature should be -20℃~+60℃, the relative humidity should be 10%~100%; the indoor temperature should be controlled at +5℃~+35℃, and the relative humidity should be controlled at 10%~80%, make the monitoring equipment in a good operating environment.
2) According to the instructions of each part of the Zoom Bullet Camera system, check the technical parameters and the quality of the transmission line of the monitoring system every month, handle the hidden troubles, and assist the monitoring supervisor to set the various data, to ensure the good condition and normal operation of this equipment' each part' functions.
3) Thoroughly inspect the parts of the Zoom Bullet Camera equipment that are prone to aging once a month. Once the aging phenomenon is found, it should be replaced and repaired in time, such as the video head.
4) Maintain the monitoring equipment that works for a long time regularly once a month.
5) Monitor the operation of the Zoom Bullet Camera system and equipment, analyze the operation, find and
troubleshoot in time.
6) Optimize the Zoom Bullet Camera system and equipment regularly every month.
7) Provide the monthly regular information service: for example, on the first working day of each month, last month's repair and maintenance records should be submitted to the person in charge of the monitoring center, in the form of electronic files.
