After the apple bagging season, the rainy season began from June to August. Some fruit farmers heard that “tomorrow has rain†and they did not spray on the same day. This often missed the best period of disease prevention and made it easy to make the disease. Due to the increased humidity caused by the high humidity in the rain, the leaves may be infected with pathogenic bacteria and cause defoliation.
After the apples are bagged, the spray nozzles must be rough, and fine spray nozzles should not be used. When spraying, be careful, branches and leaves must be sprayed.
Before and after wheat harvest is the most critical period to prevent apple brown spot. Bordeaux liquid is a special drug for controlling brown spot in apple. When preparing Bordeaux mixture, high-quality imported copper sulfate should be selected and scientifically prepared. After the apples are bagged, the Bordeaux mixture should be sprayed immediately and must be sprayed before the June 20 rainfall. After spraying the Bordeaux mixture, the dosage per mu shall not be less than 300 kg.
Containerized Oxygen Cylinder Filling System
ETR can combine all parts of the Oxygen Cylinder Filling System into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks, Oxygen Generator and 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. With an oxygen booster, the oxygen pressure can reached to 15Mpa and fill in cylinders.
