Pieris rapae and Plutella xylostella are the main pests on cruciferous vegetables. The life cycle of Plutella xylostella is short, and the field generations overlap severely. It has fulminant and often causes serious damage. Combined with the current occurrence analysis, it is expected that the third generation of the diamondback moth will occur moderately to heavier this year, and the second generation of cabbage caterpillars will occur moderately to moderately. Recently, the diamondback moth will enter the peak stage of young larvae, and cabbage worms will enter the peak period of egg hatching. Farmers should promptly use drugs, focusing on the prevention and treatment of leafy vegetable moths that are in the seedling stage or before the balling, indicating the diamondback moth, and also treating cabbage caterpillars. The prevention and treatment of the young instar larvae of Plutella xylostella was carried out in a concentrated manner. After 7-10 days, the insects were treated as insects for one time. Use 8000 international units per mu/mg of Bacillus thuringiensis WP 100 g, or 0.5% emamectin benzoate EC 40 to 50 ml, and add 40 to 50 kg of water for spraying. If you need to treat maggots, add 10% imidacloprid wettable powder 30 grams per acre.
In addition, we must pay attention to the prevention and control of leafy vegetables such as leafy vegetables, legumes and tomato (Liriomyza sativae Blanchard, and pea leafminer). The control of leaf miners should be applied during the spawning period of adult eggs to the initial stage of egg incubation. Each mus of 50% ciprofloxacin can be sprayed with 15 to 20 g of water and 30 to 40 kg of water. To control whitefly, use 25% pymetrozine WP per acre, 20 grams of water plus 40 to 50 kg of spray, which can also treat aphids.
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 a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
