Sexual reproduction and vegetative reproduction are all available (fast growing). The autumn fall is 30-45 centimeters deep. The base fertilizer is 37,500 kilograms per hectare. Seed sowing in April of the next spring, worn out seed coat, or soaked in warm water, sand seeded for two months. In addition, soaking in warm water at 60°C for 4 to 6 hours, remove the seeds and put them on a warm place, cover with a damp cloth, and rinse with water twice a day. Seed sowing in July and August, without germination, can be sowing and sowing, spacing 30 cm to open 1.5 cm furrows, seeds evenly scattered in the ditch, covering 2 to 3 cm soil. Hole sowing: Plant spacing 5 cm, sowing 5 seeds per hole, after covering the soil must pay attention to the close contact of the seeds and soil, dry soil to be watered, with 30 to 37.5 kg of seeds per hectare. Rhizome reproduction: combined with spring and autumn digging kansui, coarse root medicinal, fine roots and stems cut into small pieces of 4-5 cm, with 2 or 3 buds on the top, the first year in the fall of the whole well, Rows of 30 cm open 10 cm deep ditch, 15 cm spacing between the roots flat, cover soil is flat, watering.
Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

Field management before and after the emergence of the soil, keep the soil moist, dry to water, seedlings grow 2 to 3 true leaves according to plant spacing 10 to 12 cm seedlings, no grass in this period. Rhizomes emerge from the earth after the ground is exposed, weeds are removed, grasses are prevented from growing, and crops are interplanted between crops such as grain and grain, and land is used rationally. Before freezing, the topdressing farmyard fertilizer is 2000-2500 kg.
