Early summer cabbage cultivation techniques
Second, the early preparation of early Chinese cabbage cultivation, requires early preparations, early plowing, early preparations before sowing. In case of rainy weather, it is not possible to make timely preparations and delay the sowing date. And as far as possible choose the former non-cruciferous crops, good irrigation and drainage of fertile land.
Third, the re-application of base fertilizer early-maturing Chinese cabbage due to very short growth period, coupled with high density, high-yield cultivation must ensure that the soil has sufficient nutrients to meet the growing needs of Chinese cabbage high-yield. Therefore, before the preparation of the soil, the organic manure and urine or compound fertilizer should be applied, and the sorghum should be prepared according to the cultivation habits of various regions.
Fourth, timely sowing timely sowing is one of the key measures for high yield of early maturing Chinese cabbage. According to the local climate conditions in the year, do not blindly sow early, otherwise it will often lead to serious damage caused by disease. For a new early-maturing Chinese cabbage variety, farmers should try a small-scale trial to explore the optimum sowing date and market demand for this early-maturing Chinese cabbage and properly arrange the sowing date to obtain the best benefits.
Fifth, the early set of seedlings as early as ripe Chinese cabbage due to rapid growth, short growth period, it should be early seedlings, early seedlings and reasonable close planting. Qimiao began seedlings after a total of 3 times. When the seedlings grow to 5-6 true leaves, the last time the seedlings are set.
Sixth, fertilizer and water early In order to get cabbage early maturing and high yield, must be fertilizer early, so that the rapid growth of cabbage, sowing one day after the water, to ensure that 2 to 3 days Qimiao. "To achieve three water Qimiao, Liushui Dingmiao." Seedlings in the seedling stage must be watered once in 3 days. Always keep the ground moist and reduce the adverse effects of high temperatures on the seedlings. Seedlings were watered 5-6 days later in the seedlings. Top dressing with quick-effect fertilizer is good, after the seedlings can be applied per acre urea 10-15kg, in order to promote the growth of the outer leaves, in the Chinese cabbage cabbage ball to the core before the re-apply topdressing, acres of urea 250kg, and combined with the prevention and treatment of pests spray Fuer 655 to meet the needs of Baoxin ball, immediately after each fertilizer, watering, in order to promote the absorption of cabbage as soon as possible and high yield.
VII. Pest Control Super-early-maturing Chinese cabbage cultivation is extremely vulnerable to insect pests, especially in the early stage of emergence. If the control is not timely, it is likely that 3-5 days will allow the soil preparation seedlings to be eaten by pests. Therefore, the management requires that every day 5-7 days after the Chinese cabbage seedlings be treated with high efficiency and low residue pesticides. Can choose to respect the head, Wanxi, Sanqing, Datong pass and other prevention and control hanging filarial; prevention of soft rot can use Fengning, new life, etc.; downy mildew can be used to prevent epidemic Po, cream safety, cream urea zinc, the effect is very good.
Eight, timely harvesting and timely harvesting is the key to improving the economic efficiency of early-maturing Chinese cabbage. If the collection is too late and the disease is not controlled in time, it will easily lead to disease and cause a reduction in production. Generally in the ball bag to 7-8 into the beginning of a large number of harvested and listed to ensure high yields.
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.
