The crape myrtle is known as a hundred-day red, full house red, and itchy tree. It is a deciduous shrub or small tree of Lysimachia. (1) Sowing and raising seedlings Harvested seeds from November to December and dried. In the next year, sowing in February-March, soaking in warm water of 40-50°C for 2-4 hours, sowing in the bed and furrow of sandy loam seedlings, covering the grass after sowing. Seedlings are shaded after emergence, when seedlings reach seedlings up to 3 cm in length, and leave seedlings at a distance of 10-15 cm. During the June-August period, 2-3 times of fertilizers were harvested, and watering and weeding were performed timely. The seedling height can reach 50-60 centimeters that year, and the north needs wintering. In order to ensure safety, the seedlings should be excavated in the fall to be planted, the nursery should be transplanted in the spring of the following year, and planted in the early spring of the third year. (2) Cutting and seedling raising techniques In the early spring budding one-year-old branch cuttings, cuttings 15 cm long, base step / 3 into the seedbed, pay attention to spray water, the survival rate of up to 90%. After survival, remove and cultivate. In the summer, semi-woody shoot cuttings can also be used in the same year. They need to be fully enclosed in plastic sheds and shaded under shading conditions, or they can be bred under full sunlight using electronic leaf gap spray. Oxygen Cylinder Filling System
ETR Oxygen Cylinder Filling System
By PSA principles, ETR PSA oxygen generators generate 93%±2% purity oxygen gas directly from compressed air. ETR oxygen cylinder
filling plant is consisted of Atlas Copco air compressor, Parker dryer and
filters, air buffer tank, ETR PSA Oxygen Generator, oxygen buffer tank,
oxygen receiver tank, diaphragm oxygen booster, filling station and control
cabinet.
Compressed air is purified through the air dryer and
filters to a certain level for main generator to work with. Air buffer is
incorporated for smooth supply of compressed air thus to reduce fluctuation of
compressed air source. The generator produces oxygen with PSA (pressure swing
adsorption) technology, which is a time proven oxygen generation method. Oxygen
of desired purity at 93%±2% is delivered to oxygen buffer tank for smooth supply
of product gas. Oxygen in buffer tank is maintained at 4bar pressure, then
reach to 150bar to filling cylinders with an oxygen booster.
