Spring is a crucial period for the growth and development of vegetables in various facilities, and it is also the peak period for various diseases and insect pests. The major diseases and insect pests of vegetable plants in Fengxian County include gray mold, powdery mildew, downy mildew, tomato leaf mold, eggplant early blight, late blight, virus disease, and whiteflies. The prevention and control of diseases and pests adhere to the principle of "prevention-oriented, comprehensive prevention and control." Policy, do a good job of agricultural control and pharmaceutical protection. 1. Agricultural control: Strengthen field management, reasonably regulate temperature and humidity, promptly ventilate and reduce humidity, adopt under-membrane irrigation method to reduce disease occurrence. 2. Physical control: Hang yellow plate to kill whiteflies in the field, the height of seedling is 10-20cm higher than the top of the crop, and the height of adult plants is appropriate to the middle of the vegetable crops. Hang 25cm15cm yellow plates 60-80 blocks per acre. Use from the seedling stage can reduce the insect pest population base number. 3. Chemical control, spray prevention and control in the early stage of pests and diseases. Every 7-10 days, spray the following chemicals 2-3 times continuously. (1) Botrytis cinerea: 0.3% eugenol solution per mu for 100ml, or 300ml CFU/g WP for Harm 100-150g, or 200ml live spores per gram of Trichoderma Wet powder 500 times, or 50% of procymidone wettable powder 2000 times, or 40% of pyrimethanil suspension 500-600 times, or 50% isoprenil wettable powder 1000-1500 times spray. When the tomato is cultivars, adding 0.1% 50% iprodione or procymidone in the liquid can reduce the diseased flowers and fruit. (2) leaf mold: mu with 0.5% berberine aqueous solution 200-250 ml, or 50% isoprenil wettable powder 1000 times, or 10% difenoconazole water dispersible granules 1500 times, or 50 Permethoxil dry suspension agent 3000 times, or 40% fluorosilicone EC 8000-10000 times, or 70% thiophanate-methyl wettable powder 40-50 grams/mu spray. (3) Cucumber downy mildew and late night blight of eggplant vegetables: 500% of 1% ssoxamycin suspension, or 0.3% matrine, 140 g/mu, or 8 billion live spores/ml of spores of lichens Bacillus 130-260ml/mu, or 50% dimethomorph WP 1000 times, or 64% oxalozumason MnZn wettable powder 400 times, or 53% refined metalaxyl MnZn 500 times spray; eg In case of rainy weather, it should not be sprayed. Use 20% chlorothalonil or cymoxanil and its compounded aerosol to fumigate. (4) Early blight: 10% difenoconazole water dispersible granules 1500 times or 50% isoprenil wettable powder 1000-1500 times. (5) Powdery mildew: spraying 2% pyrimidine nucleoside antibacterial agent 200 times at the beginning of the disease, 10% difenoconazole water dispersible granules 1500 times, or 50% thiobacillus dry suspension agent 3000 times or 40% Fluosilazole EC 8000-10000 times. (6) Bemisia tabaci: In the flourishing period of Bemisia tabaci nymphs, 25-gram/liter doxorubicin suspension 50-80 ml/mu, 0.5% matrine 500-800 times, or 25% imidacloprid can be used interchangeably. Wet powder 3000 times, or 25% buprofezin WP 1000 times, or 22% of floxamidine nitrile suspension 15-22 ml/mu, etc., to reduce the damage to greenhouse vegetables, and delay the development of drug resistance . Advocates the use of island hormones (5% amino oligosacin), 6% oligosaccharides, and other plant immune-inducing agents on vegetables to promote the growth of vegetables, improve the quality of vegetables, and enhance the resistance of plants to bacteria, fungi, and viruses. And the ability of pests. Containerized Oxygen Generator
Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and oxygen generator. Even the optional 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.
