High-quality fruit tree virus-free cultivation is an agricultural high-tech. Practice has shown that cultivation of virus-free fruit trees can increase yields by more than 30% without increasing input, and can significantly improve the quality of fruit trees.
Virus disease is the enemy of fruit tree production. It weakens the growth of the tree, lowers the yield, and decreases the quality of the fruit until it dies. The virus is mainly transmitted through grafting, pruning, etc., and spreads along with scions and seedlings. Once infected with a viral disease, fruit trees are poisoned all over the body (but there may be no virus at the tips of the stems and roots), and they will suffer for the rest of their lives. In the early stage of infection, the symptoms were not obvious. With the growth and reproduction of fruit trees, the virus accumulated year after year and it was difficult to prevent or control with chemical agents.
The roots of fruitless non-toxic seedlings are well-developed and grow robustly. They have the characteristics of early flowering, early fruiting, fruit smoothness, high yield, stable production, etc. Fruit growers should pay attention to the following points in the cultivation of non-toxic fruit seedlings:
1. There must be certain isolation conditions for the planting sites. For example, planting citrus non-toxic seedlings should be more than 500 meters away from the old orange orchard and nursery. The non-toxic seedlings of deciduous fruit trees should be more than 150 meters away from the old orchard.
2, planting density is less than the density of ordinary seedlings. Such as Joe anvil short-stemmed apple, dwarfing interstock apple, pear non-toxic seedlings, planted with 55-83 per acre is appropriate.
3, the frequency and amount of fertilization less than ordinary seedlings.
4, pruning should be light, especially in the fertile soil cultivated pears, apples and other trees, mainly to take open angle, thinning, twisting tips, continuous picking, short cuts and other pruning measures to control the prosperous, ease the tree potential and promote Flower bud differentiation.

Oxygen Cylinder Filling System

With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%±3% purity oxygen gas from compressed air directly.  ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet. 


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. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
