First, the breeding method. Leek breeding methods can be divided into two kinds of sexual and asexual reproduction. The former is propagated by seeds, with high propagation coefficient, strong plant viability, long grain distribution, long life, and high yield; the latter is propagated by ramets and can be carried out at any time, but the propagation coefficient is low, viability and delivery power are weak, and the life span is short. ,Low Yield. Sexual reproduction is mainly used in production. Second, seed collection technology. Amaranth is a male and female flower, cross-pollination plants, insects flowers. When collecting seeds, it is required to isolate 1000-2000 meters from other varieties to ensure the purity of seeds. Amaranth is a perennial plant and cannot be seeded in the year of sowing. It blooms only in the following year, and can be seeded every year. The 1-2 year old leeks are in the young stage. After 3 years, they are in the advanced stage. It is advisable to use 3-5 year old plants as the seed collection plants. The seedlings of amaranth flowering and seeding need to consume a lot of nutrients, so a piece of farmland cannot be planted every year. The cultivation and cultivation of leeks can be combined with the production of commercial alfalfa, that is, after the leeks production field reaches a good age, one piece of land will be selected for next year's production. After the plot was selected, the management was strengthened in the first year, and less harvest was required. When harvested, the stubble was 2-3 cm higher than the normal production plot. After fertilization, irrigation and irrigation are needed to promote plant growth and robustness. In late June, the seedlings will be guarded against budding and lodging. In July, the plants were convulsed one after the other to combat the grassland. Plants in the first half of August should be flowered and less watered. The leek flowering period is as long as 50-60 days. Flower buds of full flowering period should be reserved. The flower buds of the initial flowering and final flowering stages should be removed to make the seeds mature basically. In order to prevent the buds from lodging, the two adjacent flower buds can be bundled together or stand. Hua Xie seeds should be top-dressed when grouting, so that the grain is full and full. Before and after the beginning of October, the calyx begins to turn yellow. The color of the pericarp should be observed to collect the seeds in time, and the seeds should be harvested before becoming too thin. If the seeds are late, the pericarp will be cracked and the seeds will fall off. It should be when the pericarp has yellowish green or a few pericarp has cracked. Cut the ball in the early morning. The bulbs are dried and threshed, the seeds are picked out, the debris is removed, the species, date of harvesting, etc. are indicated and stored separately. Every 667 square meters of farmland can receive 50-80 kg seeds. After the mother plants have collected seeds, because they consume a lot of nutrients, the growth is significantly weakened. It is advisable to fertilize and irrigate them to promote their growth. For plots that are not cultivated, young calyx should be picked in time to reduce the consumption of nutrients.
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.
