Zhang Zongqin, an associate professor at Northwestern A&F University’s College of Forestry, reminded farmers that the management of grape harvesting aftermath is very important. Management of fertilization and pest control should be done in time to lay a foundation for high production and stable production in the coming year.
Timely clearance of the garden, prevention of disease and insects removal of weeds in the garden, the litter of the orchard and pruned branches and leaves, as well as diseased fruit, diseased ear, diseased leaves and diseased branches that were discarded in the garden after fruit picking, were concentrated in the park. Deeply buried or burned to eliminate the source of pests and diseases. In addition, this year, the grapes were affected by downy mildew, powdery mildew, white rot, and brown spot. Therefore, grape fruits can be sprayed alternately with 50% Ketu WP 500 times, 65% WP WP 500 times, and 70% thiophanate WP 1000 times. Spray once in ten days.
Controlling the leggy branches will consume a large amount of nutrients in the tree body. It should take measures such as topping and wiping off secondary shoots to control its growth, so as to reduce the invalid consumption of nutrients, and promote the growth of the main vines and the retained secondary shoots, and the fullness of the buds. . Can also be sprayed 0.05% than the long-term solution inhibited prosperous, at the same time, should also be reasonable to trim the vines, thick branches to stay, thin branches stay less, over dense branches, thin branches, pests and branches should be removed as soon as possible.
Timely application of post-harvest fertilizer 1 After harvesting grapes, timely spraying foliar fertilizer to restore vigor. Spray a 0.2% urea, 0.1% magnesium sulfate and 0.2% potassium dihydrogen phosphate mixture every 10 days or so. Spray three times. 2 heavy base fertilizer. The basal fertilizer should be re-used before the deciduous leaves of the grapes, soil compost, circling, composting, etc. per acre, human and livestock manure, nitrogen, phosphorus and potassium compound fertilizer, and potassium dihydrogen phosphate.
Timely soil loosening, flood control and drought prevention are the reasons for picking and management. The soil is easy to be practised. Once the fruit is harvested, an cultivator loose soil should be used immediately. Deep plowing soil should be carried out from September to October. Deep plowing can be combined with fertilization. When the rainwater is raining for a long time, it should be drained in time. In case of autumn drought, it should be timely irrigated to maintain the appropriate soil moisture. The autumn orchards are overgrown with weeds and have poor soil permeability. Therefore, timely cultivating and weeding after fruit-picking and deep-turning are beneficial to the loose air, water, fertilizer, and new shoot growth.
Reducing Damage After harvesting some of the growers' grapes, a large number of cut off secondary shoots and old leaves not only affect the ripening of the shoots in the year, but also easily trigger winter buds, seriously affecting the growth and results of the following year's plants. Generally, no picking leaves and less shoots are removed after harvesting. Keep strong foliage. At the same time, mechanical damage to the branches and leaves is prevented during field operations to ensure that the branches are normally mature.
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.
