Which kind of grass is good

Because farmers cannot fully understand the quality and use of pasture, introduction of pasture often has some blindness. In order to avoid risks, it is necessary to make some understanding of the various areas suitable for planting pastures and suitable livestock and poultry before introducing pastures, so as to improve the efficiency of planting and breeding operations.
In general, monocotyledons such as ryegrass, Mexican corn, Sudan grass, and imperial bamboo grass have high crude fiber content and are suitable for feeding herbivores such as cattle, sheep, rabbits, geese, and fish. The majority of dicotyledonous forages, such as American corn pods, Rumex, and more tender pine cone herb, are more suitable for feeding pigs, rabbits, chickens, ducks, and fish.
For the purpose of mowing grass, one or two years of grassy wood, red clover, grain pods, etc. can be selected. For the purpose of establishing grazing land, we should choose varieties with perennial and strong regeneration ability, such as perennial ryegrass, alfalfa, and pine cone herb. Perennial and annual pastures cannot be interplanted, otherwise the yield will be affected.
The pine cone herb, because of the bristles on the leaf wall, the palatability of the feeding animals is slightly worse, not as good as that of the grains and Rumex. In fact, the more palatable and highly nutritious pastures are not as good as sweet potato pods. In fact, grain pods have been grown in China for a long time, and Rumex has also been a hybrid model of the sour model (high stem spinach).

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.
