Due to the high humidity and high temperature in the greenhouse, the disease is widespread and heavy. Therefore, controlling the disease is the key to the success or failure of greenhouse vegetables. The main diseases of vegetables in greenhouses vary according to cultivated varieties and management conditions. The main diseases include disease, anthrax, powdery mildew, soft rot and downy mildew. With the gradual harvest of vegetables, the number of vegetables in the greenhouse will gradually increase, then gray mold, anthrax, and blight will occur. Greenhouse disease prevention and control should be strictly controlled, especially in the seedling stage, flowering period to adopt conservative prevention and control, prevention-based strategy, every 7 to 10 days to prevent and cure, found diseased branches, diseased leaves must be timely picking burned, such as the incidence of heavy, humidity in the greenhouse Should be changed to smoke agent control.
The disease can be 86.2% cuprous oxide water dispersible granules or 20% thiazole copper suspension; powdery mildew can be used 15% triadimefon wettable powder; gray mold can be used 50% procymidone wettable powder; anthrax can be used 50% Forford zinc WP or chlorothalonil.
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.
