The management method of pest control cultivation
Cultivation and planting : produced in the south of China. The smiling flowers can be propagated by cutting, high pressure and grafting.
The cutting method should be carried out from the end of July to the beginning of September. It is possible to take a lint of 3 to 8 leaves or a top bud of about 15 cm, and leave the roots at the base of the cuttings. On sandy soil, proper shading and keeping the environment moist, rooting can take place in about 2 to 3 months, and then transplanted in Hunchun; the high-pressure method is most suitable for flowering, that is, between April and May. The best, if the selection of the age of 2 to 3 years of strong branches to carry out the soil pressure, it can take root after 3 to 4 months; less commonly used in the industry, the grafting method should be implemented between May and June, often It is based on magnolia as a rootstock and can grow quickly after it has survived. The roots are thick and fleshy, and the flowers are not resistant to transplantation. If it is necessary to transplant, it is better to carry the soil ball, and the pruning and shaping of the plants are suitable before wintering.
Disease prevention and control: with a smile, warm, humid climate, not suitable for exposure to the sun, not tolerant of severe cold. The plant should be placed in a weak place.
Potted plants should use loose and fertile acidic soil; watering should be carried out by dry-drying method (that is, the principle of “seeing dry, pouring, not pouring, drying and pouringâ€), not too much, so as not to cause rotten root death. . Every spring, you need to change the pots and trim some dense branches to keep the ventilation and light. After the flowers, you should cut the fruits to ensure strong growth and flowering.
It is often caused by scale insects, which can also induce soot disease. The scale insects can be removed with a small brush, or sprayed with a twenty-fifth oil emulsion with 150 times of water: the soot disease can be scrubbed with water or sprayed with water 500-1000 times. The carbendazim aqueous solution is controlled.
Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
