Q: Black spots appear on the tomatoes and the low spikes are severe.
A: This is the performance of tomato ulcer disease in fruit, also known as tomato fruit bacterial spot disease.
Cause: With ulcer disease
Solution: Tomato canker is one of the most important dangerous diseases of tomatoes and must be highly valued. It is necessary to start preventive work well from the seedling stage. In the fruit growing period, if the disease is found, it is necessary to promptly conduct drug control. The emergency treatment measures are as follows:
1. Drug Irrigation: Irrigation with Hypertonic Copper + Chloramphenicol
2, foliar spray: use "Kang Fat + see killing + red full garden" spray, 3-5 days again, even spray 3 times.
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.
